Title: Video response testing apparatus
Inventor: SHRECK PETER KURT
IPC: G06F3/0354
Filed: 1983-07-12
Abstract: Apparatus for testing the response of a viewer to questions or problems displayed on a video screen comprises apparatus to modulate the video signal to display coded patches on the screen. The patches are digitally coded by raising and lowering the luminance signal of the video (Fig. 4) without destroying spacial variations of the signal in the patch. The coding is detected by a probe having a light guide pointer conducting light from the video screen to a photo-detector in the casing of the probe. The coded luminance variations are read by the probe and produce response indications such as sound or light signals which qualify the response. The apparatus is useful as a teaching aid. <IMAGE>

Title: Variable speed replay of digital audio with constant output sampling rate
Inventor: MCNALLY GUY WILLIAM WHITSEY
IPC: G11B27/00
Filed: 1985-08-23
Abstract: The apparatus comprises a manually operably device (16, 50) producing pulses PP which directly or after integration, determine the rate of replay (f<sub>v</sub>) of the digital audio. These pulses are counted by a counter (70). Each pulse corresponds to 1.5/500 s audio. The counter (70) is reset at the rate f<sub>s</sub>/2048 where f<sub>s </sub>is the constant output sampling rate and its contents are held in a latch (72) whose contents are inversely proportional to the replay sampling period. Adders (74, 76) add the contents of the counter (70) into overflowing accumulators (78) and (80) clocked at the 48KHz fixed sampling rate f<sub>s</sub> and 128 times this rate respectively. The number (SPR) of the first accumulator (78) represents the sample displacement (d) while the MSB of the second accumulator (80) provides the replay clock f<sub>v</sub>. The sample displacement (d) represents the displacement between an output sample and an input sample and controls a two stage interpolation by way of a finite impulse response filter and a linear interpolating filter.

Title: Electrical outlet accessories with incorporated automatic circuit breaker
Inventor: CLIVES STANLEY WILLIAM
IPC: H01R13/713
Filed: 1986-01-13
Abstract: A mains electrical outlet accessory incorporating automatic circuit protection provisions has contacts which are opened by fault detection provisions. In order to employ automatic circuit protection provisions in a mains electrical outlet accessory of a resettable type, the present invention provides contacts which are of materials capable of withstanding much heavier currents, at least on a transient basis, for multiples of the normal fuse disintegration times, to allow the aforesaid contacts to be automatically opened without disintegration or welding together. Such contacts utilise a high conductivity material such as silver intimately associated with other materials having a much higher resistance to physical disintegration and/or welding together, such as tungsten, titanium oxide and molybdenum. It is also proposed to use contacts of the aforesaid materials and properties in other switched mains electrical accessories intended for use with any circuit incorporating automatic circuit protection provisions of a resettable type having the aforesaid contacts. <IMAGE>

Title: Method of and apparatus for pressure bonding two bodies together
Inventor: FOX ALAN JOHN
IPC: B23K20/02
Filed: 1986-04-25
Abstract: Method of an apparatus for pressure bonding two bodies 2, 4 together, in which method a layer of a malleable metal is evaporated onto each of the bonding surfaces which are substantially flat. When the total thickness of bonding metal between the bodies must be small, for example, less than 1 micrometre when bonding a block of an acoustic medium to a piezoelectric element in order that the acoustic losses in the bond material should be acceptable, the surfaces of the bond material must be quite clean when the bond is established. The layers of the malleable metal are produced from an evaporation source 20, 21, 22 which is situated below both the bonding surfaces in order to mitigate deposition of spits on the bonding surfaces. The pressure bond between the two bodies is established inside the evaporation chamber 19 without exposing the bonding surfaces of the malleable metal to the ambient atmosphere. This is achieved by employing a jig formed in two parts 1, 3 linked by articulated links 5. Both parts holding the respective bodies, are initially suspended over the evaporation source (Figure 1), then, before pressing, one part 3 is pushed off the carrier rod 12 by a lever 14 and falls into position (Figure 4) below the first part 1. <IMAGE>

Title: Lock and release device for couplings
Inventor: HATTON CHARLES HENRY
IPC: E21B17/043
Filed: 1986-06-06
Abstract: A lock and release device 10 for use in an assembly 24 of components 26, 28, 30 coupled together by screwthreads has two members in the form of discs 12. Each disc 12 has a plurality of helical cam surfaces 16 which are complementary to and cooperate with the corresponding surfaces 16 on the other disc 16. The helix angle of the surfaces 16 is greater than the helix angle of the threads of the assembly 24. Relative rotation of the discs 12, for example caused by frictional engagement with the ends of the shafts 26, 28 of the assembly 24 as torque is applied to tighten or loosen the assembly 24, causes the device 10 to increase or decrease in thickness thereby to lock or release the assembly 24. <IMAGE>

Patent GB-2181251-A (GB)
Title: Movement transducer
Inventor: VERE DUNCAN WRIGHT
IPC: A61B5/113
Filed: 1986-09-18
Abstract: Respiration or pulse monitors must be able to detect the very small movements which occur in the chest wall while a person sleeps. The invention provides a movement transducer having a resilient housing 11 containing a coil 10 and permanent magnets 14 mounted for rotation. In use the housing is taped to the body and a tape 15 attached to the magnets 14 is pulled through a slot 16 and attached to the body at some distance from the housing 11. Small surface movements due to respiration in the extended measurement base formed by the tape 15 cause the magnets 14 to rotate and induce an e.m.f. in the coil 10. Respiration can therefore be monitored by monitoring this e.m.f. The tape may be replaced by a rod. The arrangement may also be used to monitor flexible pressure vessels and to provide an alarm. <IMAGE>

Title: Segmented tape format video tape system
Inventor: REITMEIER GLENN ARTHUR
IPC: H04N9/804
Filed: 1987-01-14
Abstract: A hierarchy of video standards is provided in a recording format for video record and replay systems to achieve performance flexibility, such as in regard to television studio and portable recording equipment. This recording format divides the tape into a plurality (6, 7) of longitudinal segments with each segment being assigned to tracks in which full raster information (Y, I, Q) is recorded at a fractional resolution equal to the quotient of one divided by the number of the plurality of longitudinal tape segments. For example, pixels of the respective raster scan lines may be distributed across the segments; odd number raster scan lines may be in one segment, even number lines in the other; or odd and even fields may be in respective segments; thereby allowing full or half resolution. Recording formats are illustrated (Fig 1, 5, 7c, 8c, 11), as are head arrangements (Figs. 3, 6, 7B, 8B). Record/replay arrangements are detailed (Figs. 9, 10, 12). <IMAGE>

Title: Pressurised metering dispenser; manual actuator; sampling
Inventor: WESTON TERENCE EDWARD
IPC: B01L99/00
Filed: 1987-03-06
Abstract: A pressurised metering dispenser comprises a main reservoir (3), a liquid metering chamber (19) and a gas chamber (7). Valve means isolate the reservoir and the gas chamber from an outlet nozzle (27) at the end of a central passage (9), the inboard end of which is above the level of liquid in the reservoir (7) when the dispenser is held nozzle-down. A gas holding chamber (21) communicates with the gas chamber (7) and the liquid metering chamber (19) with the reservoir (3) in a normal state, and actuation is achieved by upward displacement of the nozzle (27) and valve member (23) to isolate liquid and gas holding chambers (21) and (19) from their supplies and finally cause the chamber (21) to communicate with the chamber (19) via passage (25) to cause the liquid to be expelled through the nozzle under gas pressure. A holder for such a dispenser includes a manual actuating lever and counter to indicate the number of actuations. A modified sampling dispenser includes a sleeve which is resiliently displaceable relative to the lower end of a nozzle and indicates an extension of known internal volume into which liquid can be drawn by upward displacement, for mixing with reagent subsequently ejected through the nozzle on actuation of the dispenser. <IMAGE>
