Title: Improvements in or relating to Winding Machines particularly for the Stator of Electrical Machines
Inventor: DANIEL HARRY
IPC: H02K15/085
Filed: 1967-10-05
Abstract: 1,159,286. Winding stator coils. ELEKTROMAT VEB. 5 Oct., 1967, No. 45525/67. Heading B3A. Stator winding machine has a device for keeping constant the wire being wound, comprising a bell-crank lever controlled by a camplate and having a first roller associated therewith, a second roller carried by a fixed part of the machine, the wire being tensioned by alteration of the distance between the rollers, characterized in that the bell-crank lever is hinged to a winding member by its pivot point and that the lever is guided, by the arm opposite to the first roller, along a fixed curved track, which rotates the lever during reciprocation of the winding member and maintains constant tension in the winding material. An arm 4, on which the winding head (not shown) is mounted, is guided by rollers 3 between the sides 2, 2<SP>1</SP> of a track and is reciprocated by an oscillating lever 6 which is connected to the arm 4 by a pivoted link 5. Secured to the end of the arm 4 is a bracket 7 in which a bell-crank lever 9 is pivotally mounted at 8. A follower roller 13 is mounted at the end of one arm of the bell-crank and runs on a cam formed by the edges of plates 14, 14<SP>1</SP>. The plates are secured to the device by bolts 15 which pass through slotted holes 16, so that the effective shape of the cam can be altered by drawing apart the plates 14, 14<SP>1</SP> and filling any gap between them by an insert (not shown). Wire to be wound on to a stator is drawn from a supply spool, over a brake, through an aperture 17 in the frame and then led over a guide roller 12, a roller 11 mounted on the oscillating lever 6, over a roller mounted on the other arm of the bell-crank lever 9 and then passes to the winding head. The shape of the cam-plates 14, 14<SP>1</SP> is such that as the tension in the wire tends to vary, due to the reciprocating movement of the winding head, the bell-crank lever 9 is oscillated about its pivot 8 and maintains the tension constant.

Title: Radiation Energy Measurement.
Inventor: SCOTT BRIAN FREDERICK
IPC: G01K17/00
Filed: 1966-10-14
Abstract: 1,167,877. Measuring a pulse of radiation. NATIONAL RESEARCH DEVELOPMENT CORP. Sept.28, 1967 [Oct.14, 1966], No.46156/66. Heading G1A. [Also in Division C7] A cone calorimeter for measuring the energy of a pulse of radiation has an angle and an internal reflecting surface such that multiple reflection of such radiation produces a substantially uniform radiation density in the region of the cone tip, and a temperature sensing element is secured to the exterior of the tip of the cone. The cone is made to be of low thermal capacity and high thermal diffusivity and measurement of the temperature rise of the tip provides an indication of the energy of an axially applied pulse. A total cone angle of 30 degrees and a reflectivity of 65% which is said to give a 90% absorption are exemplified, the angle always being such as to cause a parallel beam to leave the device when a parallel beam is axially applied. Electrode arrangements and solutions for manufacturing by electro-deposition a nickel-copper-nickel cone are described, and a copper-constantan thermo-couple, or a thermistor, is suggested for temperature sensing. The device is described for measuring the energy of a laser pulse, the cone being mounted in a block of aluminium, having a cone-shaped cavity, by a plastic bush. The energy is ascertained by multiplying the tip temperature rise by a calibration factor experimentally obtained by applying a plurality of temperature sensors to a number of points axially along and around the cone. An alternative platinumsilver cone is suggested.
