Title: Method and apparatus for reproducing copies
IPC: B41M5/398
Filed: 1963-01-07
Abstract: 979, 740. Thermographic printing. W. ZINDLER, [trading as LUMOPRINT ZINDLER KOMM.- GES.]. Jan. 7, 1963 [Jan. 27, 1962] ,No. 631/63. Heading G2C. A method of reproducing matter on copy material by means of radiation utilizes a coating on the copy material that melts at high temperature, the coating being selectively melted due to radiation when superimposed on an original to be copied, the melted coating being fixed by the application of colouring matter to produce a contact between the melted and unmelted portions. As shown a coated copy sheet is placed on a table 23 of a copying apparatus and an original is superimposed thereon, the two sheets then being fed through a slot 24 to a rotating cylinder. The cylinder 19 carries clamping hooks 43 which, upon engagement with a circumferential member 29, close to the 43<1> position to grip the two sheets. The two sheets are fed past infra-red radiators 42 in a chamber 38 and then past a roller 65 which applies colouring matter from a trough 63 to the melted areas of the copy sheet. Alternatively, powder 70 Fig. 4 (not shown) is supplied from a hopper 71 by a roller 69 rotating at high speed. The sheets are removed from the cylinder 19 by the hooks moving to the 43" position Fig. 3, (not shown) and are directed out of a slot 23. The copy sheet may be coated with wax e.g., paraffin wax ceris in wax or resins such as colophony, hydrated colophony, colophony ester and polyterfene. Other coatings may be polyamides, polymers of acrylic acids, ethyl, acrylate, butyl methacrylate, butyl acrylate, polystyrene, and polytetrafluorethylene. In a modification the pigment and coating may be applied simultaneously to the support sheet after heating.
Patent GB-718484-A (GB)
Abstract: 718,484. Gyroscopic apparatus. BENDIX AVIATION CORPORATION. Nov. 28, 1952 [Dec. 4, 1951], No. 30270/52. Class 97(3) A directional gyroscope comprises an indicator having a shaft driven by the gimbal of the gyroscope, a dial rotatable with respect to the shaft, a pointer adapted to be connected to the shaft by a clutch including a magnet, and manually operable means including a shifting fork or the like, for separating the pointer from the magnet to disengage the pointer from the shaft and for then rotating the pointer and dial bodily together with. respect to the shaft. Additional manually operable means may be provided to rotate the pointer alone relatively to the shaft. In the form shown, the indicator of a directional gyroscope whose rotor axis is maintained horizontal by a torque motor controlled by a pendulum actuated switch com, prises a pointer 15 movable over a dial 31 and observable through a window. The pointer is attached to a hub 17 of magnetically permeable material rotatably mounted on a. shaft 21 geared at 27 to the outer gimbal 29 of the gyroscope and is normally clutched to the shaft by a magnet 25 rotatable with the shaft and contacting the hub. In order to follow a set course when the pointer is in a predetermined position and the craft mounting the gyroscope is on course, there is provision for rotating the pointer and dial together relatively to the gyroscope. To this end there is provided a knob 65 connected by bellows to a shaft 67 rotatably and axially adjustable in a web 41 and having a spring loaded detent for maintaining it in adjusted position. This shaft carries a gear 69 engaged by a fork 77 which is pivoted at 91 in the web and through which passes a rod 73 carrying gears 71, 75 and a spring 89; gear 75 meshes with a gear 55 which is axially movable on and rotatable about shaft 21 and has a clutch face 59 for co-operation with a clutch face 60 on the hub 17 of the pointer. Thus, when knob 65 is depressed, fork 77 pivots into engagement with gear 75 so that the latter is moved to engage the clutch 59, 60 for driving the pointer 15 and also moves axially a sleeve 83, rotatable with the gear 55 and carried on a flange thereof, to engage a clutch for driving the dial 31, so that subsequent rotation of the depressed knob causes simultaneous rotation of the dial and pointer. In order to correct the pointer reading a similar mechanism is provided for rotating the pointer alone, Fig. 4 (not shown).

Title: Electronically controlled system to select automobile turning direction indicators with self cancellation
IPC: B60Q1/40
Filed: 1979-08-13
Abstract: Turning indicators in general use on most vehicles are mechanical, and have a tendency to fail, causing expensive repairs. This system is reliable due to a minimum of mechanical parts subject to wear and tear, and allows much freedom of location for easy access and convenience of operation. The system makes use of solid state thyristors (SCR-s), a segmented wheel switch, with or without a reduction gear, or a lineal switch and a switch for selecting the required direction. The system can operate through a normal flashing unit directly from the SCR-s provided a 'keep alive' resistor is inserted in parallel to the flasher. <IMAGE>
Patent GB-2036339-A (GB)
Title: Measuring dew point
IPC: G01N25/68
Filed: 1979-11-21
Abstract: Apparatus for measuring dew point is arranged to carry out a method in which there is repeatedly performed a measuring cycle in which a polished body 10 on which dew can form is cooled gradually by Peltier effect means 11 until the formation of dew thereon is detected by a photocell or the like 16, the temperature at which dew forms on the body being detected by a thermocouple device 128 recorded in the apparatus, and the temperature of the body being subsequently allowed to rise prior to cooling again in the next succeeding cycle. The temperature of the body is monitored continuously and the rate of cooling of the body in each cycle is controlled in dependence upon the difference between the instantaneous temperature of said body and the dew point temperature measured in a preceding cycle and recorded in the apparatus, in such a way that the rate of cooling is lower for at least a range of temperatures closer to said dew point temperature recorded in said previous cycle than for instantaneous temperatures of said body further from said dew point temperature recorded in said previous cycle. Thus, it is possible to combine the advantages of a rapid cooling rate, affording a high sampling frequency, and of a slow cooling rate, affording good accuracy. <IMAGE>

Abstract: A method of extracting and concentrating small quantities of precious metals such as gold, silver and platinum contained in high sulphur content base metal sulphide ore residues comprises mixing the ore residue with extra copper or other suitable base metal, e.g. by pelletising with powdered copper, smelting and casting the mixture to form a two phase block having an upper lighter layer rich in sulphur and a lower denser metal layer rich in the precious metals and then treating the lower layer for the recovery of a concentrate containing the precious metals. If the correct amount of copper or other base metal be added a relatively small lower layer is formed so that the precious metals are not too dispersed and a sharp line of demarcation if formed between the two layers. <IMAGE>

Title: Security arrangements in data transfer equipment
IPC: G07F7/10
Filed: 1980-09-05
Abstract: The equipment comprises a control station, e.g. telephone booth equipment, and a portable data carrier, e.g. a pay token, the data in which is altered by interaction with the control station, for example to reduce a stored money value by the cost of a telephone call which has been made. A security check operates by means of a reference signal and a test signal held in the storage station, the reference signal selecting a corresponding test signal in the control station for comparison with that of the dens storage station. When bistable DB36 presents a R(right) output, a valid test signal is sent to the storage station from one of register S21 to S24 selected in accordance with the reference signal entered in shift register S20 which selects one of the bistables DB21 to DB28. When DB36 presents a W(rong) output, an invalid test signal is supplied by register S29. DB36 switches once for each transaction and therefore present W and R outputs in unpredictable sequence. The responses of the storage station to both valid and invalid signals must be correct before data alteration is permitted. The registers S21 to S28 allow replacement of the test signal and reference signal held in the memory of the storage station. The registers available for this can be selected by signals on a' to h'. New test signals can be entered on lines 1 to 8 so that some test signals are available only for checking and not for re-use and others are no longer available (out of date pay token). <IMAGE>
