Title: Apparatus for registering the area of hides or pieces of leather
IPC: C14B1/00
Filed: 1960-12-01
Abstract: 902,323. Area registering apparatus. STROJOSVIT, NARODNI PODNIK. Dec. 1, 1960 [Jan. 18, 1960], No. 41433/60. Class 106 (1). In apparatus for registering the areas of pieces of leather, decimal digits corresponding to the area are automatically stamped on to the leather and entered by electromagnetic means into a mechanical adding machine. A piece of leather 5 is gauged by a mechanical gauging machine 2, of the pin or roller type for measuring areas, and the deflection of an integrating lever mechanism 1 is converted into the angular deflection of a pointer. This is sensed by a numerical feeler 3, e.g. an electric contact pick up, transformed by electrical means to a decimal digit value and transferred to the input of an electromagnetically operated mechanical adding machine 6 so that the sum total of the measured areas is indicated on paper tape. Simultaneously, the digit value is transferred to a stamping device 4 in which digit wheels 7 are set, e.g. by means of electromagnetically operated ratchet wheels and pawls, and the indication of the area is recorded on the leather.

Title: Apparatus for intermittent film transport
IPC: G03B1/18
Filed: 1963-10-24
Abstract: 986,446. Cine film transport apparatus. FERNSEH G.m.b.H. Oct. 24, 1963 [Oct. 24, 1962], No. 41990/63. Heading G2E. An apparatus for transmitting television pictures at 60 frames per second from a cine film running at 24 frames per second comprises a film transport component such as a claw 23, which is driven by a double crank arranged between two transformation gears of the transformation ratio u and 1/u. The distance between the bearings 6 and 8 of the two cranks and the phase relation of the driven shaft 2 is chosen such that the driven shaft is turned by an angle at 180 degrees, when the driving shaft 1 is alternately turned by an angle at 180. u. m/n degrees and 180. u. n-m/n degrees respectively, where m and n are integers other than 1. By this means the shaft 2 which drives the claw 23, has a periodically varying angular speed derived from the constant angular speed at driving shaft 1, and for 60 frames per second transmission, the film successively is halted at the projection gate 27 for alternate periods at 1/30 second and 1/20 second. In the gear shown in Fig. 1, toothed wheels 3,5,10 and 11 are shown, wheels 5 and 10 on shafts 4, 9 are interconnected by crank 7, the displacement of the shafts resulting in the above periodic variation in the angular speed of shaft 2. An extension of shaft 1 drives the sprocket drum 30 at constant speed, while claw 23 is driven by shaft 2 through gears 46, 47 and the eccentric 43 on shaft 42. The claw works with a clamping check 24 and clamping gate 25 and air pressure difference 26 applied to the film below gate 25. The pneumatic film transport system is described in Specification 863,082. In the present apparatus each film picture is scanned alternately twice or three times by the raster 56 of costant frequency on the screen of cathode ray tube 55, and light from this screen, modulates by the film is focused on photo-cell 58 to produce electric signals for transmission. It is not necessary for the take-up sprocket 30 to be driven at constant speed when the film is out to be transported through a sound head after the gate 27.

Abstract: 1,221,576. Drum dryers. CONTROLS CO. OF AMERICA. 9 Sept., 1968 [22 Sept., 1967], No. 42752/68. Heading F4G. [Also in Division H2] In a dryer, the dryer drum motor M, the heater, and a moisture sensing circuit are controlled by switches 52, 53 and 54 which are controlled by cams 10 rotated by timing motor 12. To start, timing motor 12 and cams 10 are rotated by hand by means of a knob to close switches 52, 53 and 54. When the appropriate degree of dryness is reached, timing motor 12 is energized by the moisture sensing circuit and static cams 10 to open switches 52, 53 and 54. Timing motor 12 only rotates if an alternating current is applied to it. In the sensing circuit, the positive half-cycle of the A.C. waveform is blocked by silicon controlled rectifier SCR being non-conductive but the negative half-cycle of the waveform is passed by diode D3. A current flows through resistor R1, diode D1, resistor R3 and rotary switch 51 to -a' moisture sensing ring 14 inside the dryer drum, then through the moist cloths to earthed ring 16. The magnitude of the current flow will depend upon the moisture content of the clothes. The voltage at junction 18 will also appear at junction 20 and be applied across a neon bulb N1. When the voltage across the neon bulb reaches the firing point of the neon bulb it becomes conductive to supply a pulse through resistor R5 to gate 22 of silicon controlled rectifier SCR which is rendered conductive Therefore both half cycles of the A C waveform can flow 'through timing motor 12 which begins to rotate. During positive 'half-cycles capacitor C1 is charged and during negative half-cycles capacitor C1 discharges through SCR to keep it conductive even though neon N1 may'have extinguished.

Abstract: 1,201,056. Time control of electric circuits. TEXAS INSTRUMENTS Inc. Sept.22, 1967 [Jan.9, 1967], No.43262/67. Heading G3T. Also in Division H1] Timing apparatus particularly for a programme control of electric circuitry comprises pairs of thermistors 11, 12, 13, &c., connected to power supply lines L 1 , L 2  the thermistors of each pair being electrically connected to one another and being of opposite temperature co-efficients, and the thermistors are so arranged that heat generated in a thermistor of one temperature co-efficient in a pair, e.g. the thermistor P11, is transferred to a thermistor of the opposite temperature co-efficient in an adjacent pair, e.g. to the thermistor N12. Before commencement of the programme cycle the thermistors are in a cool stable state, but on closing a switch PB1 a thermistor PT1 is energized to heat a thermistor N11 having a negative temperature co-efficient and connected in series with a thermistor P11 having a positive temperature co-efficient. Heating of the thermistor N11 causes an increase of current therethrough and a higher voltage to be applied to the thermistor P11 so that the latter self heats, and also heats the thermistor N12 of the adjacent pair. The latter then self heats and returns heat to the thermistor P11 to produce a steep rise in its resistance. The current through the pair P11, N11 is thus reduced so that they return to their stable cool condition. Subsequent pairs P12-N12, P13-N13, &c., become activated in a similar manner so that lamps such as 21, 23, 25 connected to various pairs become energized at different times, either to indicate the condition of the system or to operate photosensitive devices for the programme control of electric circuitry. Additionally a thermistor or thermistors, such as the thermistor TH1, may be provided to sense the heat dissipated from any of the thermistors in the pairs and effect various programming operations. The programming sequence may be made repetitive by closing a switch SW1 to connect in series with the thermistor P11 and a thermistor N11A heated by the thermistor P18 of the final pair. In an alternative system the thermistors are so arranged that each two thermistors between which heat is to be transferred are mounted on a common support. In a further system the thermistors of each pair are electrically connected in parallel.
