Title: Automatic searching system
IPC: G06K17/00
Filed: 1971-08-26
Abstract: 1365701 Statistical apparatus etc.; selective signalling EASTMAN KODAK CO 26 Aug 1971 [3 Sept 1970] 40120/71 Headings G4M and G4H A microfilm strip 10 has frames 12 besides each of which is an optical mark 22. The strip carries a magnetic stripe 20 which typically stores a computer program between lines 1, 2, data between 2, 3 descriptive of documents recorded on the strip, data descriptive of and providing an address for the frames on the strip between lines 3, 4 and after line 4 frame-related or other data. To search the strip data descriptive of the reel and of the document on the reel is entered by a keyboard 36 into registers 26, 28, 30, 32, 34, switch 38 is operated and motor 18 is run at a low tape reading speed. The program is read and applied to system control and clock 50 and to register 52 the output of which is disabled until a specified word is read and compared with a word in a register coincidence circuit 54. Gates 55 are set to be opened by a clock pulse train and words read are fed to circuits 58, 60, 62, 64, 66 to be compared with words in registers 26-34. On coincidence with the two words in registers 26, 28 indicating the correct reel AND circuit 68 is enabled to inhibit gate 70 and cause the motor 18 to continue to run at low speed. If a wrong reel were chosen the motor would be stopped. The strip is driven until three successive descriptor words are successfully compared with the words in registers 30-34 and the address following the words is read into a buffer register 78 via gates 76 enabled by AND gates 72, 74. While the motor is being driven the number of marks 22 is counted on counter 82 and the digital difference between the actual and required counts is converted to analogue form in D.A. converter 86 which resets flip-flop 42 to run the motor at high speed in either a forward or reverse direction. The actual count is fed to a comparator 84 during high speed running and a zero volts detector 92 fed by the converter stops the motor drive at the required address or can detect an approaching zero voltage to switch to a low speed to facilitate zeroing. To reduce the possibility of errors in the frame address count, beside each frame may be an n bit binary number, e.g. 4 bits which is optically read and fed to the last n bits of the counter (Fig. 3, not shown).

Abstract: 1368186 Refrigerating; defrosting SARLAB AG 31 Aug 1972 [3 Sept 1971] 40405/72 Heading F4H In an inert gas absorption refrigerating apparatus, the high temperature part 29 of the evaporator is defrosted by hot refrigerant condensate flowing from the condenser 25 through a conduit 26 into heat exchange with the evaporator when the circulation of gas in the gas circulation system is blocked by the liquid refrigerant which is continuously collected in the bend of a U-pipe 36, which is termed the third level, until a first level is established at the lower end 41 of a conduit 33 in the evaporator to prevent gas flow therethrough and the pipe 36 is periodically emptied by syphonic action when the liquid level rises to a second level above the highest point 44 of a siphon 43. As shown, gas weak in refrigerant, is prevented from flowing into the lower end 41 of the conduit 33 whence in normal flow it is conducted into contact with refrigerant condensate at the upper end 27 of the evaporator. The siphon is connected to the absorber vessel 21 and the U-pipe is connected by one leg 40 to the vapour space of theboiler 15. In a modification, Fig. 2, the U-pipe is situated between the evaporator and absorber vessel in a conduit for rich gas in the gas circulation system, the liquid seal being formed at a first level which is above the upper wall of the bend of a U-tube.

Patent GB-1567761-A (GB)
Title: Radioreceiver switching
IPC: G08G1/09
Filed: 1976-10-01
Abstract: The circuit arrangement (7) is installed in a VHF receiver. The input of the circuit arrangement is connected to the output of the frequency demodulator (4) of the VHF receiver. The auxiliary carrier frequency is filtered out by means of a filter (10, 12). A first signal dependent on the auxiliary carrier amplitude is generated with a diode (14) and a transistor (17), and a second signal dependent on the modulation of the auxiliary carrier is generated with an amplitude demodulator (21, 22, 23). These two signals control a threshold value switch (30) if the amplitude of the auxiliary carrier and the amplitude of the characteristic range frequency in each case exceed a specific value. On receiving a traffic broadcast transmitter, the circuit arrangement initiates a switching operation which indicates to the user that his receiver is tuned to a traffic broadcast transmitter. <IMAGE>

Abstract: 862,943. Tensioning binding straps. POWER STRAPPING SYSTEMS Ltd. Dec. 15, 1959 [Dec. 23, 1958], No. 41416/58. Class 45. A lever operated tensioning tool for flat strip bale ties is characterised in that the drive from the lever 41 to the tensioning capstan 34 is through a two speed gear. The tool also incorporates a spring gripper 18 and a guillotine blade 26 operated by a handle 30. The tool comprises a casing 12, 13, 14 containing a driving shaft 32 and a driven shaft 33 which carries the capstan 34, a wheel 37 and a gear 39. Solid with the driving shaft 32 is a pinion 36, which meshes with the wheel 37, and free on the shaft 32 is a gear 38 which meshes with the gear 39. Integral with the gear 38 is a sleeve 40 on which the lever 41 runs loosely. On one side of the lever is a rocket wheel 43, which is secured to the gear 38, and on the other side is a ratchet wheel 44 which is keyed to the shaft 32. The pawls 45 and 47 for the ratchet wheels are each mounted on a pivot on the side of the lever. At the top of the lever is a push button 51 which is connected through a rod 52 and a resilient coupling 59, 60, 61 to a transverse pin 49 which at one end engages a notch in the tail of pawl 45 and at the ther end engages pawl 47 at a point between the tooth and the pivot of that pawl. When the button is depressed, the pawl 45 is disengaged from the ratchet wheel 44 and the motion of the lever is transmitted through the ratchet wheel 43 to the gear 38 and hence to the capstan. The low speed ratio is engaged by releasing the button so that the pawl 47 is disengaged and the drive is through ratchet wheel 44, to the pinion 36 and the wheel 37.

Abstract: 1,162,986. Removing particles from gases. GENERAL ELECTRIC CO. 20 Sept., 1966 [23 Oct., 1965], No. 42022/66. Heading B1R. In a method of removing particles from a gas, a condensable vapour, e.g. steam, is added to the particle-laden gas and subsequently condensed and condensed droplets containing particles are removed from the gas, the amount of condensable vapour added to the gas being controlled by the difference in temperature between the particle-laden gas and the mixture of such gas and the condensable vapour. The condensable vapour may be injected into the particle-Laden gas or the particle-laden gas may be bubbled through a body of a vaporisable liquid maintained on a bubble tray having means to heat the liquid. The condensable-vapour may be condensed by contacting the mixture of gas and vapour with tubular cooling elements and the condensed droplets removed by filtration. Alternatively the gas and vapour may be passed through a body of liquid maintained on a bubble-tray having means to cool the liquid. The removal of the particles from the gas may take place in a number of superposed stages.

In the embodiment shown, one half of a metal strip 5 is corrugated by successive roll pairs 9a, 10; 12, 13;, 14, 15; 16, 17. An edge flange 19 is formed by rolls 32, 33, a central U-section seam element 18 by roll pairs 23, 24 and 28, 29 and an edge U-section seam element 20 by rolls 34, 35. The strip is then coiled by roll sets 41, 42 (not shown) 43, 44 into overlapping helical convolutions so that flange 19 is received into element 18, and the latter into element 20 to form a seam locked by pinch rolls 66, 67, to produce a tube having an inner plain wall 8 spaced from the corrugations of outer wall 7. The lower roll sets 41, 42, 44 consist of individual rolls shaped to accommodate the adjacent part of the strip, and the upper roll set 43 of two rolls 55, 56. All coiling rolls are adjustable about axes perpendicular to the plane of the advancing strip. In a modification insulating material is laid between seam elements 18 and 20 so as to lie between the walls of the finished tube. In another embodiment, louvres are formed in the part of the strip which will become the inner wall, so that air may be blown into the centre of the tube from between the walls, Figs. 15 and 16 (not shown), to facilitate transport of particulate material in an air stream. Either or both walls may be smooth, corrugated, or provided with openings, and the seam may be welded.
