Abstract: 1278510 Thermoelectric devices HEWLETTPACKARD CO 16 Dec 1969 [16 Dec 1968] 61200/69 Heading H1K A signal energy sensor comprises a plurality of thermocouples arranged with their cold junctions in a better thermally conductive relationship to a base than are the hot junctions, and resistive heating elements coupled to the hot junctions so that they are heated by electric signals applied to the heating elements. As shown, Fig. 2, an Al foil 53 is coated with a layer 55 of insulating material such as Al 2 O 3  or SiO 2  and slots 57 are etched in the foil to form a substrate with areas having different thermal capacities. A plurality of layers 56 of Bi are vapour deposited and are connected by vapour depositing a plurality of overlapping layers 58 of Sb to form cold junctions 62 above the remaining parts of the Al foil and hot junctions 60 above the slots in the foil. A layer 61 of SiO is deposited over the hot junctions or over the whole surface and a Ni-Cr resistive heating strip 64 is arranged on the hot junctions. The thermoelectric strips may form a pair of meandering tracks on a single base, each array being provided with its own heating strips, Fig. 1 (not shown). The Al may be removed from the edge of the base. The thermoelectric strips may also be of Si and Ge or of Fe and constantan.

Title: Phosphorus Acid Dyestuff Compositions Containing Polymeric Stabilizers
IPC: C09B69/00
Filed: 1978-08-30
Abstract: A composition comprising an aqueous solution of a dyestuff bearing at least one phosphorus acid group and a polymeric material, such that the tendency of the composition to deposit solid is reduced compared with a similar aqueous solution without polymeric material and such that the composition may be handled conveniently, e.g. poured easily from containers at ambient temperatures.

Title: Ring laser gyroscopes
IPC: H01S3/083
Filed: 1979-04-20
Abstract: A ring laser gyroscope has one or more weaker secondary laser modes, operating slightly above the laser threshold, coupling with stronger primary counterpropagating laser modes to produce a dithering effect which reduces or eliminates lock-in between the primary modes. Cavity length control circuitry 32 may be provided to detune the cavity length to allow two secondary opposing modes (40, 42) to be generated Figure 3 (not shown). Alternatively, an external laser beam source (74) may generate the secondary waves Figures (not shown). Finally, part of one of the primary waves may leave the ring laser path through a partially reflective mirror and be acted upon by an oscillating mirror (94) which doppler- shifts the frequency. This mode is reintroduced into the ring laser path to couple with the primary mode Figure 6 (not shown). <IMAGE>

Title: Improvements in or relating to tape recording and playback systems
IPC: H03G3/34
Filed: 1979-06-29
Abstract: A magnetic tape recording and playback system 10 is disclosed in which the message recorded on the tape is in the form of spaced signal bursts of predetermined frequency and the playback system 12 delivers the recorded message to a gate 20 the output of which is fed to an output stage 24 and the gate is controlled by a comparator 21 having one input predetermined and the other input derived from the message recorded on the tape by means of a level detector 22. The gate 20 is opened only when the detected level of the message exceeds the level of the predetermined input to the comparator 21 and this eliminates unwanted audio echo signals. The reference input to the comparator may be adjustable. In the recording circuit 11, a signal from a source 17 is periodically passed through a gate 15 to a recording stage 18, the gate 15 being controlled by an adjustable- period integrated circuit timer 16. The gates 15 and 20 may be F.E.T.'s and the stages 18 and 24 may be operational amplifiers. <IMAGE>

Title: Bolt mechanism
IPC: E05B59/00
Filed: 1979-09-12
Abstract: A primable lock for use, for example, for securing railway car sleeping bunks comprises a bolt housing 1 which contains two outwardly biased bolts 3, 4 and a priming mechanism including a cam 8. The cam 8 is accessible by e.g. a square key, from outside the housing to turn it to the position shown in which it maintains the first bolt 3 in its retracted position, but releases the first bolt when the second bolt 4 is urged into the housing and contacts the cam, thus allowing both bolts 3 and 4 to move outwardly. The lock is intended for use with a striking plate which has a recess able to accommodate both bolts so as to hold the bolts securely in the recess when the bolt 3 is released, the recess having an inclined exit groove such that, when the first bolt 3 is held in its retracted position, second bolt 4 may be urged along the exit groove and up the incline thus releasing the first bolt 3 as the second bolt 4 is urged into the housing by the incline. <IMAGE>
