Patent GB-990126-A (GB)
Title: Prosthetic parts and method of making same
IPC: A61F2/30
Filed: 1962-10-15
Abstract: Artificial bone, especially for use in a hip joint prosthesis, comprises an inert ceramic body.  This is preferably porous, the pores being continuous and communicating and the pores are preferably filled with a synthetic resin to give increased flexural strength to the structure.  A suitable ceramic material is made from alumina, silica and magnesium and/or calcium carbonates.  This is shaped and pre-fired at between 1600 DEG  and p  2000 DEG  F. to decompose the carbonates and give a porous, open cell structure.  It is relatively soft and may be readily worked by ordinary tools to the desired dimensions, after which it is finally fired at between 2300 DEG  and 2700 DEG  F.  Introduction of the synthetic resin, which is preferably an epoxy or polyurethane resin, is carried out in a closed chamber by initial evacuation followed by impregnation with the resin under pressure.  To assist fixation of the prosthesis by bone or tissue growth it is preferred to have the superficial pores of the shank free from resin and this may be achieved by dipping it in a solvent, such as methylene dichloride, or by initially filling them with wax which is subsequently removed.  Two forms of hip prosthesis are described, one of which is made solid from porous, ceramic material while the other has a tapering hole throughout the length of its shank so that the finished product has a core of synthetic resin.

Patent GB-1143358-A (GB)
Title: Improvements in information processing systems
IPC: G06F9/48
Filed: 1966-10-21
Abstract: 1,143,358. Hybrid computers. ADAGE Inc. 21 Oct., 1966 [22 Oct., 1965], No. 39567/67. Divided out of 1,143,356. Heading G4A. A digital computer including an instruction register and means for executing instructions stored in the register, provides service to an array of external devices in response to service requests from said devices and in accordance with predetermined priority assignments, the requested service being defined by an external instruction provided by an external instruction source associated with each external device. Each external device has an associated priority channel PR0-PR4, PR0 being of highest priority. When an external device requires servicing its request signal such as RQS1 enables gate 445 so that when the computer is ready to step to the next instruction, R1F is set by #SAR. The setting of one or more request storage flip-flops such as RIF causes generation of an interrupt necessary signal INN which in turn generates the command "fetch priority instruction" FPI. The signal FPI forces the computer to select the external instruction source corresponding to the set request storage flipflop of highest priority and to transfer the instruction word from the external source to the instruction register via a memory input/output register. The corresponding service storage flip-flop PS0F-PS4F is set, indicating that service has been initiated, and the highest priority flip-flop R0F-R4F which was set, is now reset. When the external instruction has been executed, the set flip-flop PS is reset, and the stored programme is resumed, provided no further requests for service are extant. The external devices may be imput/output devices. The generation of an unassigned special instruction code may be used to produce a service request from the highest priority external device and the external instruction gated out of the corresponding external source may cause the computer to execute an error sub-routine. The disclosure is identical with that of Specification 1,143,356.

Abstract: 1,215,009. Automatic intruder alarms. J. DAICH and M. N. KEENE. 26 March, 1968 [1 Sept., 1967], No. 40123/67. Heading G4N. [Also in Division H3] A remote warning alarm device for a vehicle or premises comprises an R.F. transmitter 1 and a portable receiver 5 having a plug-and-socket connection means 6, 7, the arrangement being such that when the receiver is connected to the transmitter by the connection means the transmitter and receiver are maintained in a switched off condition, but when the receiver is disconnected from the transmitter the transmitter is maintained in a standby condition in which actuation of one of the trip means 3 causes transmission of an alarm signal to set off the alarm 8. The plug-and-socket connection has an individually coded pin arrangement. Fig. 2 shows a transmitter circuit suitable for use in a vehicle. When the receiver is plugged in, terminals V and O are connected and relay RL1 is energized and holds switch S open. When the receiver is disconnected, switch S closes and a relay RL2 is energized, breaking the ignition and starter solenoid circuits in the vehicle. After a time delay (to allow the driver to leave the vehicle and shut the door) determined by R 2  and C 1 , a silicon controlled rectifier SCR1 is triggered to energize the R.F. transmitter (shown to the right of line I-I<SP>1</SP>). Subsequently, if one of the trips 3 (which may be associated with the doors, windows, bonnet, boot, petrol tank cap, and ignition and lighting systems) is actuated, a negative voltage appears at terminal N or a positive voltage at terminal P so that transistor T becomes conductive and triggers a second silicon controlled rectifier SCR2 to energize a multivibrator T 5 , T 6  which turns the R.F. transmitter on and off, thus modulating the transmitted R.F. signal. Also, after a time delay determined by R 8  and C 4 , a third silicon controlled rectifier SCR 3  is triggered to energize a relay RL 3  to set off an alarm 4 on the vehicle. The transmitter 1 may have a metal casing held at a high voltage with respect to the vehicle chassis when in the stand-by condition. If the transmitter is damaged, absence of the steady R.F. signal at the receiver will signify an alarm. Operation of the starter solenoid may be initiated automatically when the receiver is plugged in.
