A Selection of Equipment of Use in the Production and Maintenance of Aircraft, Missiles, Space Vehicles and Components. Thomson Industries, Inc. has developed a new product. This product is the T/C Mill‐Drill Table and has applications in small, medium and large plants engaged in drilling, milling, and similar operations.

To identify the papers, and publishing journals, describing psychiatry, surgery and paediatrics research funded by the National Health Service (NHS) in the UK. To make comparisons with non‐NHS research and examine the journal impact factors, and importance to clinicians, of journals publishing the most NHS research. To consider the implications, including those for research assessment.

Existing databases were examined: the research outputs database (ROD), which contains information on UK biomedical papers; NHS ROD, which contains details of papers on ROD funded by the NHS; lists of journal impact factors. These were combined with selective findings from surveys conducted to identify journals read and viewed as important for clinical practice by psychiatrists, surgeons and paediatricians.

In each specialty many papers publish NHS‐funded research and they out‐number the non‐NHS papers in the ROD. They appear in a wide range of journals but in each specialty one journal is clearly the most used. The impact factors of journals publishing the most NHS research vary considerably. In each specialty the journal containing most NHS publications is widely perceived to be important by clinicians.

Much NHS‐funded research is also funded by other bodies. Clinician survey response rates were between 38 per cent and 47 per cent. The analysis could be extended to other specialties.

Papers published in the few journals in each specialty that are viewed as important by clinicians could be given additional credit in assessments.

This paper describes outputs from NHS research and shows how assessment could be extended.

Reed buys MDC and maps out European plans … European expansion is a key element in the acquisition of Mead Data Central by Reed Elsevier, according to MDC's President, Rod Everhart. A name change is also in the works, as is the loading of Reed Elsevier databases.

In an aircraft in which the wings 10 can be moved from a spread position, tig. 1, to a swept‐back position, fig. 2, the spars 11 extend into the fuselage and are hinged together at 12, movement of the wings being effected by a hydraulic jack 14, 15 connected to links 13 whose ends are respectively connected to the spars and a fixed pivot 131.The fore‐and‐aft movement of the wings consequent upon their angular adjustment ensures that the longitudinal trim of the machine remains substantially constant. To prevent fouling of the leading edge root portions of the wings when the latter are spread, these portions are formed as separate members 16 pivoted to the main wing sections at 17, their displacement being effected by links 18 whose rear ends are connected to fixed pivots 19 or, alternatively, against the action of springs 20 when they engage fixed abutments 21. The wing loads are transmitted to the fuselage by vertical rods 23 secured to the fuselage, their upper and lower ends engaging curved slots 22 in the wings, or by the reverse arrangement in which vertical rods 37 are secured to the wings and engage slots 36 in the fuselage.

GENERALLY speaking, the demand for thermo‐electric pyrometer equipment is such that individual calibration of each instrument and its couple is possible. For the measurement of aircraft temperatures thermo‐electric pyrometers are employed but the following conditions render individual calibration impracticable:

How does the top man forget office problems in his leisure time? This month, John Lawless talks to Lord Thomson, who, among other things finds pure enjoyment in reading balance sheets. Picture: John Benton‐Harris
