Title: Improvements in and relating to fashioning plastic foam
IPC: B29C44/56
Filed: 1960-05-26
Abstract: A piece of soft, resilient, plastic foam, e.g. polyvinyl chloride, polyester, polyurethane or isocyanate foam is temporarily made rigid by saturating with a liquid, e.g. water, and freezing the liquid, shaped while rigid, and then restored to its original soft and resilient condition.  The rigid foam thus produced can be cut, carved, or otherwise shaped in the same way as a piece of wood or other object of rigid material, after which the frozen liquid is thawed.  The method is of particular use in the manufacture of surgical pads, finger or toe caps of tubular form and bunion or enlarged joint pads.  Partial or full insoles can be cut for use with foot appliances.  In the embodiment described, a piece of the rigid foam is turned in to cylindrical form and then drilled lengthwise from one end, almost to the other end, thus making a finger or toe cap.

Title: Improvements in and relating to transformer on-load tap changing means
Inventor: WILLIAMS EDWARD
IPC: B60L9/26
Filed: 1956-06-19
Abstract: 853,021. Control of motors. ENGLISH ELECTRIC CO. Ltd. June 14, 1957 [June 19, 1956], No. 18953/56. Class 38 (3). [Also in Group XXXV] An on-load tap changing arrangement for a transformer secondary winding 10b which has tappings A, B, C, D, comprises a centre-tapped auto-transformer 15 whose ends are connected to on-load switches 16, 19 the other sides of which are bridged by an off-load switch 22 and each connected to a group of off-load switches connected to the secondary tappings. The switch 16 is connected to even-numbered switches 17, 18, and the switch 19 to oddnumbered switches 20, 21. The output voltage is derived between one side of the secondary winding and the centre tap 15a and is utilized to drive a traction motor 14 which may be for A.C. or, if a rectifier 23 is introduced, for D.C. In a modification the arrangement shown forms one half of an arrangement based on a centretapped secondary winding to provide full-wave rectified D.C. The switches are operated by a controller movable to various notches, the onload switches being of the pneumaticallyoperated or electro-pneumatically-operated type and actuable by cam gear coupled to the controller. In operation in the "off" position switches 16 and 19 are open. Movement of the controller to the first notch closes switches 20, 22, 16 and 19 deriving the voltage of point A. Movement to notch 2 opens switch 16 and switch 22 closes switch 17 and recloses 16 deriving a voltage midway between A and B. Movement to the next notch first opens 19, then 20 and closes 22 before reclosing 19, deriving the voltage of B. The switching movement to the next notch opens 19 and 22 and closes 21 before reclosing 19 and the switching procedure is continuable to give 7 different voltages from the four tappings. Hence the switch 16 or 19 is opened temporarily whilst one of its group of off-load switches and the switch 22 are operated to change a tapping.

Abstract: 1299911 Dental handpieces CKD PRAHA OBOROVY PODNIK 21 April 1970 [21 April 1969] 18954/70 Heading A5R [Also in Division F1] A dental handpiece, the torque of which increases with loading, comprises a reaction type gas turbine with a rotor 4 fitted with tangential nozzles 8 and supported in gas lubricated bearings. It is characterised by a circular gap 5 between adjacent surfaces 3 and 14a of the rotor and stator the centre part of said gap communicating with the gas input 2 and the periphery communicating with the gas exhaust 6. Compressed gas enters through the input 2 into the gap 3 and, if the tool is not yet in place in the collet 12, the gas is simply discharged. After the shank of the tool is put into the collet 12 the gas flows through the distribution holes 10, into the ring-shaped cavity 11, through the tangential nozzles 8 out through the exhaust channel 6 and through the gap 5 between bearing surfaces 3 and 14a. When the tool is loaded, the rotor 4 is axially displaced so as to diminish the clearance 5. Due to this the proportion of gas flowing into the ring-shaped cavity 11 is increased and the torque of the turbine is increased. At the same time the pressure within the clearance increases and the bearing capacity of the turbine is enhanced.
