Title: Control for tape drive of automatic threading recorder/reproducer
IPC: G11B15/50
Filed: 1963-07-02
Abstract: To prevent a solenoid 24 from engaging a pinchroller 19 with a magnetic or other tape 10, until the ears 7 on the slotted-cheek take - up spool 2 have caught the mouse 12 on the leading end of the tape and fed it to the reel hub, a delay means holds off the solenoid 24. In Fig. 1, a tape-foil 33 bridges contacts 32 after sufficient tape advancement to energize the solenoid 24, which is then held by lock-in contents 31, a START means 21 for the take-up reel drive preparing the solenoid circuit through contacts 29. In Figs. 2 and 3 (not shown), a transparent leader tape and photo-electric sensing means act when the start of an opaque magnetic tape reaches the sensing point. In Fig. 4, the reel-drive is engaged by a solenoid 67, controlled from 68, which makes available a supply by the reel-ears 7 contacting contacts 66 to energize a suitably slow-tooperate solenoid 64 engaging the pinch roller. A pause control arrangement (Fig. 3, not shown), is arranged to apply brakes and release the pinch-roller solenoid only after the threading leader has passed the sensing point, and a flip-flop circuit, associated with the photo-electric circuit and the RECORD button ensures that recording can not be attempted on the leader, by halting the tape automatically some 10 cms. clear of it.

Title: Electrical Generator.
IPC: G21H1/10
Filed: 1967-05-10
Abstract: A power source designed for use in a heart pacer consists of a radio-active heat source around which a plurality of pairs of thermocouple wires are wound in layers, each pair having a hot junction in contact with the source and a cold junction remote from the source. To confine the generated heat to the hot junctions, a suitable reflector of heat is incorporated in the layers. The assembly is mounted in an evacuated enclosure and the heat reflector is preferably of a substance which serves to getter the vacuum, as described and claimed in Specification 1,179,955. The heat source, Figs. 1 and 2, consists of three rods 29 of Pu contained in separate tubular compartments 25 of a fuel cell body 35. This body is supported by tensioned wires 63-67, Fig. 2, of which there are three at each end of the body, and each wire passes from the body over a peg 59 or 61 to a spring clip 71 or 73 which is attached to a bracket 51 on the wall of the housing 83 enclosing the heat source. The thermocouples consist of pairs of wires 91, 93, Fig. 8, made of specified Cu-Ni and Cu-Ni- Mn alloys which are interwoven with quartz threads 103, 105 and covered with fabric 107, 109 to form a cloth in which the wires form either the warp or the woof. The couples are connected in parallel redundant pairs, the pairs being connected in series with all the hot junctions on the heat source and are wound in a spiral about it with the cold junction ends of the couples connected to a terminal on the wall of the easing 83. The generally frusto-conical spaces bounded by the ends of the heat source, the support wires 63-67, and the brackets 51 are filled with a material 171, e.g. Ti-Zr foil, which reflects heat back to the source and is also a vacuum gettering material. Like thermallyreflecting vacuum gettering material is also incorporated in the layers of thermocouple cloth by attaching a Ti-Zr foil 95, Fig. 8, to the fabric 107. The casing 83 is made in two parts 18, 20 which are electron beam welded under high vacuum. One of the parts, 18, carries the pulser 203-e.g. a solid state multi-vibrator circuitwhich is powered by the thermo-generator to provide an output suitable for use of the device as a human or animal heart pacer. The exterior of the casing consists of materials (e.g. titanium, moulded plastic) not incompatible with implantation of the device in a living creature.

Patent ES-349324-A1 (ES)
Title: Improvements in or relating to control systems for railway trains
IPC: B60L3/00
Filed: 1968-01-15
Abstract: In an arrangement for selectively actuating means on a train, e.g. for actuating couplers between vehicles, slave means are provided on each vehicle which are energized to uncouple the vehicle in response to signals from a master unit. The arrangement may also be used to return information from the slave means to the master unit. As described, the master unit is mounted on the leading vehicle of the train and is connected to each slave unit via five leads connected via the coupler units. Where the master unit is not on the train, the signals to the slave units may be by radio. The five leads include a pair of power lines 23 an address line 20 which in each vehicle is connected in series with a pair of bi-stable units 25, one associated with the front and the other with the rear coupler an order line 19 for passing frequency multiplexed signals to all the vehicles and a reply line 21 including time delays 33 for passing information from the slaves to the master unit. The series connected bi-stable circuits 25 form a shift register so that a particular circuit 25 can be energizzd by applying a pulse to the address line and the correct number of shift pulses via order line 19. The shift pulses are frequency coded, detected in the first filter and detector unit 36 and trigger a pulse generator 37 which supplies the shift pulses to the bi-stable circuits. The energized bi-stable picks up an associated relay which energizes the slave apparatus so that an uncouple signal, frequency coded and sent via the order line, is detected and operates the uncouple circuit 7 via a contact 40. In response to a further signal of different frequency an encoder 32 at the slave station is energized to send information from source 28 back to the master unit. Where information, e.g. vehicle number is required from each vehicle in the train all the bi-stables are energized then in response to the further signal each vehicle transmits the required information at the same time, the time delays 33 ensuring that the signals are received in sequence at the master unit. The head 4 of coupler 2 mounts a pivoted hook 5 normally spring held in the coupling position from which it can be released by an unlocking cam 10 connected via a shaft 9 to a lever 8 operated by an air cylinder unit 7. In emergency the lever can be operated by hand. The head also carries air and electrical couplers 6 and 3.

Title: Balanced valve with pressure sensing means
IPC: F16K39/02
Filed: 1977-05-13
Abstract: An improved balanced valve includes a radial arrray of pressure sensing passages in the main disc which extend from the axial opening to a peripheral region of the disc below the seating surface of the disc such that when fluid flow reverses, as when there is a rupture of the first flow passage, an upward force is generated on the main disc just prior to closure which tends to resist the closing force on the valve, the pressure sensing passages allowing a higher fluid pressure to be communicated to the region above the main valve disc assembly to effectively oppose this resistance to closure.
