A thermoelectric generator for supplying current to a super-conductive circuit consists of one or more plates A arranged in a vacuum vessel with one edge soldered to a metal block B provided with ribs G about which a heater coil D is disposed and the other edge soldered to a metal block C provided with ribs E immersed in liquid helium outside the vacuum vessel, the temperature differential between the two blocks (6 K. in the embodiment) giving rise to a net thermoelectric voltage. The plates which are annealed before assembly are preferably of gold or copper doped with specified amounts of iron and the blocks of extremely pure copper, and lead tin solder which is superconducting at 4K. is used for the joints. The blocks are connected - into circuit by superconducting strips H.T of corrosion resistant V 2 A steel coated with niobium-tin or niobium zirconium alloy and tinned to facilitate soldering to the blocks. The strips are soldered directly into the walls of the vacuum vessel.

Abstract: 1,251,005. Bumpers. FORD MOTOR CO. Ltd. 11 May, 1970 [26 June, 1969], No. 22626/70. Heading B7J. [Also in Division F2] An energy absorbing bumper assembly 18 for shielding a motor vehicle includes an elongated elastomeric member 22 of arcuate cross-section which is secured to a structural member 20, which may form part of the vehicle, and which has an outer convex surface 24 and an inner concave surface 26 with which the member 20 co-operates to define a cavity 28, and resiliently deformable grid-shaped web means 42 extending from the inner concave surface 26 into the cavity and co-operating with the surface 26 to define a plurality of cells opening into the cavity 28. When the assembly receives an impact there is a first deformation, Fig. 4, which deforms the elastomeric member and brings the ends of the web means into contact with the structural member 20. Thereafter the web means 42 is deformed, Fig. 5. When undeformed, the ends of the web means form a concave profile 44. The elastomeric member 22 has beads 30, 32 integrally formed with the longitudinal edges of the member and secured to the structure by clamp means 34, 36. A flexible shield element 40 is integrally formed with the elastomeric member 22 to overlie the bead 30 and damp means 34 and thus hide them from view.

A fan impeller has adjustable blades 58 which assume the closed position shown when the impeller is stationary. However, when the impeller is rotated the blades are moved into their operative open positions by a pair of centrifugal weights 74 which move radially-outwardly about pivot pins 70 to partially rotate a control member 68 through pin-and-slot connections 76, 78 and thereby move the blades through arms 66. The degree of opening of the blades can be controlled by adjustable abutments 86 for the weights 74. Compression springs 82 bias the weights into their radially inner positions. The blades may instead be adjusted by an axially-movable control member. The impeller may be rotated in the reverse direction to reverse the flow therethrough. If, however, the impeller is to be rotated in one direction only the blade pivot shafts 60 may be offset from the control axes of the blades.

Abstract: 1,265,721. Thyristor circuits. WESTING- HOUSE BRAKE & SIGNAL CO. Ltd. 3 Dec., 1969 [22 Jan., 1969], No. 3499/69. Heading H2F. In a circuit for commutating a main thyristor (not shown) by means of a capacitor 5 discharged into the main thyristor via a commutating thyristor 7, means are provided to inhibit turning on of the commutating thyristor 7 when the commutating capacitor 5 is insufficiently charged. As described, capacitor 13 is charged during positive half cycles of supply 12. At a time determined by circuit 11, transistor 10 is turned on, discharging capacitor 13 through transformer 9 so as to turn on the commutating thyristor 7. The discharge current of the commutating capacitor 5 is monitored by current transformer 17 and, after a delay of 10 microseconds, turns on a further thyristor 16 which holds capacitor 13 discharged until the next positive half cycle from source 12. Thyristor 16 prevents commutating thyristor 7 being re-triggered in the event of it being prematurely triggered by spurious pulses.

Abstract: 1303270 Digital transmission; multiplexing systems STANDARD TELEPHONES & CABLES Ltd 25 Aug 1971 [2 Sept 1970] 41988/70 Heading H4P A multiplex digital data switching centre for multiple mixed channels operating at different speeds in which storage areas are grouped within a single store with suitable access means comprises a plurality of channels operating at each speed, the centre having a plurality of data storage devices one for each channel with all the devices associated with each speed being grouped together. The incoming characters are scanned and a means for associating the scanning time of each character with a corresponding channel address in the storage devices is provided together with means for transferring the characters to the devices associated with the addresses. In a preferred embodiment the centre has a plurality of counters one for each speed which are incremented when a character at appropriate speed is scanned, the means for transferring being operated to transfer characters to the appropriate storage devices which are indicated by the counter content. Incoming channels may be bit or envelope interleaved. Assuming that a system is based on a number of basic 12 Kb/s channels in the 12 Kb/s frame with 10 bit envelope interleaving, the scan time is 20À8 Ás per envelope. The address corresponding to an incoming channel is derived by adding the base address indicating the start of a storage area corresponding to the particular channel x, y or z to the frame base address n.2<SP>M</SP> where n is a number of 12 Kb/s unirate multiplexed channels and M is a number of binary digits in the address specifying the channel within a frame, plus the address of the information channel within its own 12 Kb/s frame (m). A table giving the channel rates and corresponding forms of addresses is given in a Specification. The frame base address can be made available by permanently storing the address and extracting it concurrently with the transfer of characters on the corresponding 12 Kb/s channel. The address has the form n.2<SP>M</SP> so it is only necessary to store n providing other means available for defining the channel rate. Alternatively each channel is scanned and accessed once in each major period with the order of access within a major scan constant. With a bit interleaving the method is identical. Incoming frames may be completely aligned with outgoing frames or completely aligned with each other but not the outgoing frames. Since we have a phase difference this requires a buffer storage of say four envelopes which if set at a determined figure so that the positional change is known, a common frame address counter can be used but the delay factor slightly complicates the address formation.
