Title: Semiconductor Transducer
IPC: H01L29/84
Filed: 1968-12-12
Abstract: 1,197,540. Semi-conductor devices. MATSUSHITA ELECTRIC INDUSTRIAL CO. 12 Dec., 1968 [27 Dec., 1967 (3)], No. 59211/68. Heading H1K. A semi-conductor mechano-electrical transducer has at least one metal electrode 3 in non-ohmic contact with a semi-conductor region 2 of one conductivity type in, and forming a PN junction J 1  with a semi-conductor body 1 of the other conductivity type, and at least one further metal electrode 4 in ohmic contact with the semi-conductor body 1 such that when stress is applied to a rectifying metal electrode a variation in electrical resistance is produced between a rectifying electrode and an ohmic electrode. The semi-conductor material may be silicon, germanium, gallium arsenide, gallium phosphate, indium arsenide, indium antimonide, or silicon carbide, doped with boron and phosphorus. The rectifying contact is made of indium, silver, gold, platinum, tungsten, molybdenum, antimony, zinc, lead, tin, vanadium, rhodium or copper. In an alternative embodiment, Fig. 4 (not shown), a region (7) is formed in the semi-conductor body, of the same conductivity type but higher impurity concentration than the body, surrounding the periphery of the region (2) of opposite conductivity type. In a further embodiment an ohmic contact can be made to the semi-conductor region 2 at a distance from rectifying contact 3 so that voltages can be applied to the region to vary the energy band structure and increase the sensitivity.

Title: Vehicle lighting systems
IPC: B60Q1/26
Filed: 1972-12-23
Abstract: 1450769 Road-vehicle signalling circuits LUCAS ELECTRICAL Ltd 12 Oct 1973 [23 Dec 1972] 59585/72 Heading G4Q In a vehicle lighting system including a dimming resistor 19 in series with a stop lamp 21 a further resistor 18 is included, and transistor means sensitive to the potential across the further resistor short-circuits the dimming resistor until the stop lamp is hot; thus delay in stop lamp illumination, due to the dimming resistor, is avoided. In one embodiment transistor 41 is turned on when stop lamp switch 17 closes and thereby short-circuits resistors 18, 19; as stop lamps 21, 22 heat up the potential across resistor 18 falls and the transistor turns off. In a modification a further transistor (42 Fig. 2, not shown) is turned on when transistor 41 turns on, to short-circuit resistor 19. The circuit includes a flasher 23 and associated direction-indicator lamps 25, 26, 27, 28; a resistor 39 to ensure constant flashing rate whether or not dimming resistors 29, 31 are in circuit; and a relay coil 34, energizes when vehicle lighting switch 12 is closed, for operating contacts 36, 37, 38.

Title: Cashing machine
Inventor: ZSCHAECK HERBERT KARL
IPC: F16F1/48
Filed: 1970-12-21
Abstract: 1,259,730. Cashing machines. H. K. ZSCHAECK. 21 Dec., 1970 [24 Dec., 1969], No. 60602/70. Addition to 1,222,220. Heading G4T. A cashing machine comprises an adding device for the summation of individual data, and a coin dispenser operated by a further device which has a keyboard. In one embodiment, the further device (13) (Fig. 1, not shown) comprises a three-decade keyboard, which may be illuminated, in which each key operates to close and lock two pairs of electric contacts a, b connected to coin ejection mechanisms 240-270 through a D.C. source 40 and control keys 20, 21 which select the mode of operation. One decade only is shown. In a first mode of operation, when an amount of money tendered by a customer is a fixed programmed amount (or a multiple thereof) the cashier keys into the keyboard (19) (Fig. 1, not shown) the total to be paid as printed on the cash register check and closes key 21. The keydesk operates the coin dispenser (11) to eject the difference between the total and the fixed preset amount. The fixed amount is set by the direct connections between the keys: 191b to 199a, 192b to 198a &c. for the single decade shown and for a preset amount of 10 units. Each contact pair 191b-199b is connected to the D.C. source 40 and electromagnetic coin ejectors 240-270 upon closure of key 21, thus effecting a subtraction between the amount keyed in and the preset amount. In the second mode of operation, when the amount of cash tendered is not an integral multiple of the fixed amount, the keydesk serves merely to directly select the change to be dispensed. The change amount is mentally calculated by the cashier, keyed into the keyboard and then the control key 20 is closed, connecting contact pairs 191a-199a to the source 40 and coin ejectors 240-270, in this case no subtraction occurring. After closure of either key 20, 21 the keys 191a, 191b-199a, 199b are unlocked after a time delay to ensure reliable response of the coin ejector mechanism. In both modes of operation it may be necessary for the cashier to surrender banknotes to complete the change. The coin dispenser (11) (Fig. 1, not shown) comprises a row of coin collecting tubes (24-35), some of which eject a single coin and some two or more coins in a single operation, and a coin sorter (23). The adding cash register (10) has a keyboard (14), adding-in key (15), totalizer key (18), indicator window (16) and printed check port (17).

In a one-way clutch wherein caged balls or rollers 3 wedge between a cylindrical race 1 and a thin walled wedge shaped element 6 adjacent another cylindrical race 2, springs 7 bias the element 6 into engagement with the balls or rollers 3. The wedging balls or rollers 3 alternate with bearing balls or rollers 4 carried by a common cage 5. As shown individual springs 7 carried by the cage 5 act on the elements 6 but in Figs. 3 and 4 (not shown) all the elements 6 are acted upon by a single annular spring element. As shown the elements 6 act between the balls or rollers 3 and the outer race 2 but the elements 6 may act between the balls or rollers 3 and the inner race 1.

Abstract: 1,207,550. Mixing apparatus. L. H. BOWLES. 30 Dec., 1968 [16 Jan., 1968], No. 61654/68. Heading B1C. Mixing apparatus suitable for mixing a particulate chlorinating agent with water comprises a hopper 22 and feed screw 24 for feeding the chlorinating agent into a chamber 14 through which water is passed with a swirling motion to prevent the chlorinating agent from settling in the chamber. The swirling motion is caused by introducing the water into the chamber at a sufficiently high pressure through pipe 19, optionally fitted with a nozzle. A baffle 74 is placed within the chamber to prevent repeated circulation of the liquid therein and to direct it to the outlet 68 of the chamber. The amount of chlorinating agent added may be regulated by means of a timer 28 and the level of liquid in the chamber may be controlled by means of a float valve.

Abstract: A package comprises an article between two packaging components (10, 12) sealed together around the article. One component (12) is a sheet of fibrous board or a laminate. The other component (10) may be a moulded thermoplastic shell. The surface of the sheet (12) to which the shell (10) is sealed has a pair of cuts (16, 18) extending part-way through the sheet on opposite sides of the seal.

Title: Energy regulator
IPC: H01H37/00
Filed: 1978-06-30
Abstract: An energy regulator includes a heater 8 which is energised only when the contacts 11, 12 for controlling energisation of an electrical load L, e.g. a cooker hot plate, are open. When the heater 8 is energised it deflects a bimetallic actuator to cause the local contacts 11, 12 to close and contacts 14, 15 controlling energisation of the heater 8 to open. Should the heater 8 fail, the hot plate will not be connected to the power supply 5 thereby avoiding the risk of damage and fire. <IMAGE>

Title: Ultrasonic Scanner
IPC: G01N29/28
Filed: 1978-09-07
Abstract: An ultrasonic scanner in which one or more ultrasonic transducers 32a traverse an arcuate path with respect to a reflector 54 which converges ultrasonic waves at a point a preselected distance in front of the reflector. In general, the ultrasonic waves are converged at a point outside the scanner and inside an object to be examined to produce a sector scan in the object having its center at the convergence point. In one embodiment the reflector only partially reflects the ultrasonic waves and an additional stationary transducer is provided which is positioned to produce ultrasonic waves which radiate through the reflector and coincide with one of the lines of the sector scan, thus permitting simultaneous M-mode or pulse Doppler echo information to be obtained in perfect registration with the sector scan lines. Attenuation and anti-reflection means are provided to suppress echo artifacts. <IMAGE>
