Title: Frame member of a door or a window to which is attached a further component
IPC: E05D5/02
Filed: 1974-06-14
Abstract: 1465294 Fastening W FRACH and B JANKE 14 June 1974 [18 June 1973 3 May 1974] 26592/74 Heading E2B An assembly comprises a frame member 1, Fig. 1, of a door or a window to which is attached a component 2, the frame member or the component being provided with an aperture receiving a fastener 105 and the component or the frame member being provided with a channel 3. The latter has an opening 6 which is more narrow than the width of the channel, the channel receiving a clamping member 104 which is less wide than the width of the opening 6 and which is longer than the width of the opening 6 and smaller than the width of the channel 3. The fastener 105 engages the clamping member 104 in such a way that rotation of the clamping member 104 by the fastener 105 can be effected between a released position, where the clamping member can be withdrawn through the opening 6, and a locked position, where the clamping member 104 is retained in the channel 3 to secure the component 2 to the frame member 1. In an embodiment the fastener 105, Fig. 3, has a screw-threaded portion 118 and the clamping member 104 has a screw-threaded bore 115 and a way of ensuring that the clamping member can be rotated by the fastener consists of deforming the screw-threaded bore at 117. The clamping member 104 and a modified clamping member 204, Fig. 4, are each provided with two diagonally opposite corners which are rounded and with ramps 11, 12. Each of the latter begins at a rounded corner and rises towards the non-rounded corner. The clamping member 204, Fig. 5, has an un-threaded portion 216 in its bore which facilitates gripping with the fastener. In another embodiment the fastener 5, Fig. 13, is provided with ribs 18 which are received in grooves 16 formed in a clamping member 4, Fig. 10.

Abstract: 1,167,234. Speed control of D.C. motors. AMPEX ELECTRONICS Ltd., and A. M. HEASLETT. 12 June, 1968 [12 June, 1967], No. 27071/67. Heading H2J. [Also in Division G3] Pulses, the repetition rate of which is dependent upon the speed of a motor 10, are arranged to switch off the supply to the motor, the supply being restored a predetermined interval after receipt of each pulse. The motor 10 is fed from an amplifier 40 controlled by a bi-stable circuit which in one state only allows the motor to be energized. The motor drives a tone wheel 11 whose pick-up coil 12 feeds an amplifier 13, the output of which is squared and then differentiated to provide pulses. The latter are applied to a bi-stable circuit, the transistors 19, 22 of which are both normally non-conducting. The arrival of a pulse renders the bi-stable conducting thus applying voltage to a timing circuit 27, 28 in the collector circuit of transistor 22. When the capacitor 27 has charged to a voltage set by potentiometer 23 a transistor 35 is rendered conducting, causing a sharp pulse to appear at the collector of a transistor 33; this is applied to both a transistor 34, which resets the bi-stable, and another transistor 32, which discharges the capacitor 27 ready for the next cycle. The setting of potentiometer 23 determines the running speed of motor 10 which may, for instance, drive a tape transport system.

Title: Improvements in fractional distillation
IPC: B01D3/42
Filed: 1939-10-06
Abstract: 533,098. Fractional distillation; servomotors. FOSTER WHEELER, Ltd. (Foster Wheeler Corporation). Oct. 6, 1939, No. 27349. Addition to 461,405. [Class 32] [Also in Group XXIX] In the invention of the parent Specification, wherein the quantity of each side-stream withdrawn from a still for fractionating composite liquids such as hydrocarbon oils is automatically maintained as a definite percentage of the charge, irrespective of variations in the quantity or temperature of the charge or quantity of steam used, the ratio flow controllers 40, 48, 51 are constructed as shown in Fig. 2. Pressure difference in the lines 35, 36 is transmitted to the mercury chamber 41, and pressure difference in the lines 44, 45 is transmitted to the mercury chamber 42, thus actuating the floats 57, 58. As the float 57 rises, in response to an increase of flow of charge in the line 14, the pivoted air nozzle 54 moves to the right, and as the float 58 rises, in response to an increase of flow in the sidestream line 21, the flapper 55 moves to the right. Air is supplied at a constant rate through the line 38 and passes through a valve-controlled device 66 into lines 62, 63 and 64, so that when allowed to escape at a constant rate through the nozzle 54, by reason of constant flow of change in the line 14, it maintains a definite pressure in the closed diaphragm 60, and a constant flow in the line 21. If the flow in the line 21 increases, the flapper 55 moves away from the nozzle 54, allowing air to escape more readily therefrom, pressure in the diaphragm 60 decreases, the valve 61 is thereby moved to the left, air is admitted into the line 46, and the diaphragm-controlled valve 47 tends to close, resulting in a decreased flow in the sidestream line 21. If the sidestream flow should, for any reason, decrease, the flapper 55 moves towards the nozzle 54, increasing the pressure in the lines 64, 63 and diaphragm 60, thus moving the valve 61 to the right, reducing pressure in the line 46, and allowing an increase in the flow of the sidestream. The flow controller 31 is manually set to obtain a constant flow through the line 14, though if, for any reason, the flow in the line 14 should vary, the ratio flow controllers 40, 48, 51 cause the flow in the sidestream lines 21, 22, 23 to vary proportionately.

Abstract: 1,057,156. Data transmission. COMPAGNIE FRANCAISE THOMSON-HOUSTON. July 2, 1964 [July 2, 1963], No. 27452/64. Heading H4P. In a frequency-shift data transmission system in which the bits have equal length and comprise whole numbers of half cycles, the significance of each received bit is determined by counting the number of zero crossings and, further, any zero crossings occurring other than within Œ #t of the expected positions are judged to be error signals. In the embodiment described three half cycles in a bit period correspond to a bit of one significance and two to a bit of the other significance. #t is chosen as 1/12 of a bit period. A negative pulse, produced at each zero crossing, feeds a cascade arrangement of flip-flops having astable times successively of 3#t, 2#t and 2#t. The flip-flops control separate gates so that the next occurring transition pulse passes to one lead if it occurs from 0-3#< (indicating an error), to another if from 3#t to 5#t (indicating a 0 bit) and to a third if from 5#t to 7#t (indicating a 1 bit). These leads feed, respectively, an error indicator, a scale of three counter, and a scale of two counter. When either counter is full it passes a pulse representing a 1 or a 0 to the output of the apparatus. However, if one counter is not at zero, a pulse occurring on the input to the other counter will cause an error to be indicated and the counters to be reset to zero.
