Title: Improvements in and relating to automatic programming control
IPC: G05B19/421
Filed: 1956-12-20
Abstract: 814,425. Automatic amplitude control systems. GENERAL ELECTRIC CO. Dec. 20. 1956 [Dec. 28, 1955], No. 38873/56. Class 38 (4). [Also in Groups XXXVIII and XL (c)] An oscillator comprises amplifiers 13, 15, adjustable phase shifters 14, 17 and a phase inverter 16 connected in series, with a feedback loop including a resistor 19, the overall phase shift being 720 degrees at the oscillating frequency. The outputs from amplifiers 13, 15, which are in quadrature, are fed via power amplifiers 20, 21 to a Scott-connected transformer arrangement to give a 3-phase output, the magnitudes of the two-phase voltage input to the Scott transformers 24, 25 being automatically maintained in the correct values by feeding them into rectifiers 33, 35 where they are individually compared with reference voltages derived from potentiometers 34, 35a to control the bias for the amplifiers 13, 15. The phase angles of the two-phase voltage input to the Scott transformers are automatically maintained in quadrature by feeding them into a phase discriminator 31 producing a push-pull D.C. output voltage proportional to divergence from the 90-degree relationship, to adjust the phase shift in apparatus 14, 17 without affecting their quadrature relationship. The oscillator output is fed via an amplifier 45 to be recorded on a magnetic tape 44. During playback the pulses derived from the recorded signal are amplified at 52 and reshaped at 53 to be fed as a sine wave to the input of the oscillator first amplifier 13, to lock the oscillator to the recorded frequency. The two signals are brought into phase synchronism by comparing the output from 52 with the output from power amplifier 20 in a phase discriminator 49, any difference in phase producing a D.C. voltage which is used to modify the bias of phase shifters 14, 17 until the two signals are in phase. A further bias control is derived directly from the frequency of the recorded signal in a frequency discriminator 50. Specification 671,136, [Group XXXVIII], is referred to.

Title: Improvements in or relating to suspension filing devices
IPC: B42F15/00
Filed: 1958-12-04
Abstract: 939,676. Filing papers; index tabs. W. C. MARKHAM. Dec. 3, 1959 [Dec. 4, 1958; Oct. 7, 1959], Nos. 39193/58 and 34017/59. Classes 16 and 146 (1). A suspension bar for document files having a pair of flexible filing prongs 15 is shaped as shown in Fig. 1. To fit the bar to the file, the prongs are unclamped from clamping plate 17 and the file of documents is opened out. The prongs are flexed towards each other in the middle of the pile of documents and slid into the respective slots 2 and to the inner ends of them. The file is then reclamped. Thus the bar can be applied without unfiling the papers and, due to the slots being cranked in opposite directions, the bar cannot fall out by gravity. The slots may extend towards each other instead of away from each other. To suit papers of different distances between filing holes, the bar may have more than two slots. As shown in Fig. 1, the bar has one end hooked for single point suspension from a rail. As shown in Fig. 3, both ends are hooked for mounting between two rails in horizontal or inclined position, in which case one rail can be rotated about its axis and locked in position to prevent removal of the bar. As shown in Fig. 11, index tabs 34 and spacers 36 may be clipped to the rail, the former having cut-outs 35 to locate the ends of the suspension bars. An equivalent to the bar can be formed from bent wire (Fig. 2A, not shown). The first Provisional Specification discloses bars having apertures instead of edge slots for the prongs.

Title: Control of absorption refrigeration systems
IPC: F25B49/04
Filed: 1968-08-19
Abstract: 1,223,718. Refrigerating. CARRIER CORP. 19 Aug., 1968 [13 Nov., 1967], No. 39605/68. Heading F4H. In a continuous absorption system having a generator 12, condenser 13, evaporator 11 and absorber 10, a strong solution by-pass 80 is provided to enable the quantity of strong solution contacting a cooling heat exchanger 30 to be reduced in circumstances in which the absorber is in danger of reducing the level of refrigerant in an evaporator sump 23 to a point at which the refrigerant pump 25 might become starved. Excessive absorber capacity results in over absorption of refrigerant which in turn increases the level of solution in the absorber sump 33, and, as illustrated, a valve in the by-pass 80 is controlled according to the level of solution in the absorber sump so that the by-pass flow is increased and the absorber capacity decreased by the increase of solution level above a given level. A generator heating medium valve 60 is controlled according to the output temperature sensed at 61, and the degree to which the valve 60 may be opened by such control is limited when the temperature of incoming absorber coolant sensed at 65 falls below a given level. A weak solution valve 70 is electrically, pneumatically or mechanically linked to the valve 60 so that when the valve 60 reduces the generator capacity the valve 70 reduces the supply of solution to the generator and vice versa. In an alternative arrangement, the valve 70 may be response to the temperature sensed at 61, in which case the valve 60 is linked to follow the valve 70. When the by-pass valve 81 operates to decrease absorber capacity, evaporation in the evaporator 11 will decrease so that the temperature sensed at 61 will rise and the generator capacity will be increased. As a result, refrigerant will be supplied to the evaporator at an increased rate as a further guard against starvation of the pump 25. If there is an excessive accumulation of refrigerant in the evaporator sump 23, a float 57 opens a valve 56 to pass refrigerant to the weak solution pump 35 to prevent over concentration of absorbent solution.

Filed: 1975-10-03
Abstract: 1497097 Optical projectors S BESANCENOT 3 Oct 1975 [4 Oct 1974] 40657/75 Heading G2J As shown in Fig.2, a part 1 is pivotally mounted about an axis 2 on the pusher of a magazine slide projector. When the part 1 is in the position shown on the right, an arcuate part 3 thereof is turned to the right ready to contact a slide in the projection position. When the pusher is moved to the left, the extension 3 moves the slide back into the magazine. At the same time, a finger 5 on the body 4 of the part 1 runs in a cam groove 6 and rocks the part 1 about the axis 2 in an anti-clockwise direction as shown in the left-hand side of the figure. This ensures that the slide is pushed into the magazine before the end of the movement of the pusher. Continued movement of the pusher, and the action of the cam groove 6, causes the extension 3 to retract from the magazine before the magazine steps forward at the end of the pusher movement. A shutter 11, Fig.3, is in the closed position shown when the slide is out of the projection position. When the pusher moves to the right, a flange 22 on the pusher slides over a flange 21 on a lever 16 pivoted at 17 to the body 18 of the projector. When the slide contacts a stud 24 on the lever 16, the lever is pivoted clockwise and releases a pin 20 on the shutter 11, which moves clockwise to its open position under action of a spring 15. When the pusher is operated to return the slide to the magazine, the flange 22 engages the flange 21 to return the shutter 11 to its closed position.

Abstract: 877,059. Programme-control of machine tools. GOLDMANN, B. M. G. March 9, 1960 [Dec. 17, 1958], No. 40716/58. Addition to 778,060. Class 83 (3). A machine comprises at least one movable part, means for driving that part in two directions, pneumatic pick-up means, and means for driving a record tape E past the pick-up means, the pick-up means comprising two pairs of pick-ups, one of each pair (o) being arranged to cause the movable part driving means to move the movable part in one direction a unit amount for each unit of data on one track of the record tape which during operation registers with that pick-up, and the other of each pair (g) providing a secondary control of such movements by use of a second track. The tape has a track passing under the cowling g and the greater the number of holes under the cowling, the lower is the pressure in a line leading to a valve k<SP>1</SP>, causing the valve to rise. As the valve rises, a tapered portion thereon increases the air supply to the motor L. The jet o registers with the second track and whenever a hole passes the jet, the pressure-drop in a line p permits a spring z to move a valve q causing the valve k<SP>1</SP> to be raised. To avoid cumulative errors, a cam w, rotated by the motor L as it rotates the leadscrew n<SP>11</SP>, co-operates with a jet v<SP>1</SP> to regulate the speed of the motor. The number of holes in the track under the cowling is greater than, but proportional to, the number of holes on the other track. A track on the main tape controls a ratchet-mechanism to advance an additional tape to control additional functions such as speed-changing and indexing. The additional tape may be replaced by a disc. In a modification, the valve k<SP>1</SP> controls an hydraulic or D.C. motor.

Filed: 1965-09-24
Abstract: 1352118 Tail assemblies DYNAMIT NOBEL AG 24 Sept 1965 [28 Sept 1964] 40870/65 Heading F3A A tail assembly for a rocket having a central nozzle consists of an empennage comprising erectable fins and a cowling for the empennage, the empennage and the cowling being movable with respect to one another between a first position in which the fins are in a non-erected condition and second position in which the fins are in an erected condition and protrude through openings in the cowling, whereby when the empennage and the cowling are in said second position the cowling covers that part of the empennage between the roots of the erected fins. The cowling may be constructed as a one-part sleeve coaxial with the tail assembly and having slots for the passage of the fins. The sleeve is rotatable between two end positions, one of which is determined by the outer ends of the inwardly hinged fins and the other by the inner ends of the erected fins. Rotation of the sleeve is caused by the provision of one or more springs connected between the nozzle and the sleeve, advantageously by a helical spring wound in one or more convolutions around the nozzle. The pivot shafts of the fins may be so arranged in  relation to the sleeve diameter and the fin bushes so constructed that the latter end flush with the external surface of the sleeve when the fins are erected. Those regions of the sleeve which limit the slots on their sides adjacent the fin bushes when the fins are erected may be constructed as inwardly curved, resilient marginal strips which are applied flush with the external surfaces of the sleeve against the fin bushes. In other embodiments, the rotation of the sleeve is either effected, or else assisted, by the provision on the rearward end of the sleeve of rotation-generating blades which project into internal cross-section of the nozzle. In a further embodiment, the empennage is rotatable with respect to the cowling about the tail assembly axis. Alternatively, the sleeve is constructed as a slide bushing with rearwardly open slots for the passage of the fins and mounted on the rocket casing for axial displacement between forward and rearward end positions. Where provision is made for the locking of the sleeve in its forward end position only to be released when the fins are fully erected, the width of the slots can conform very accurately with the fin thickness. The sleeve is displaced into its rearward end position by means of one or more springs. Alternatively, the sleeve is constructed as resilient segments, equal in number to the number of fins and of cylindrical curvature, being fixed on the nozzle and extending between the fins and the nozzle. With the erection of the fins, the spring segments are displaced so as to cover the interstices between the fins, the displacement being limited by stops formed on the fin bushes.

In a diversity receiver for radio telegraphy, at least two aerials 1, 1<SP>1</SP> are connected to respective amplifiers 2, 2<SP>1</SP>, the gain of each being regulated in accordance with their combined A.G.C. voltages; and the output of each amplifier is fed through a respective limiter and a filter 3, 3<SP>1</SP>, tuned to a harmonic of the amplifier output, to an evaluating device 5, 5<SP>1</SP>. Each limiter 3, 3<SP>1</SP> comprises oppositely connected rectifiers adjustably biased to a predetermined threshold value, and the ninth harmonic of the amplifier output is passed by a filter to a modulator 4, 4<SP>1</SP> where it is converted to a lower frequency and then fed to a discriminator 5, 5<SP>1</SP>. If the combined signal plus noise output from any amplifier is less than the threshold value of its associated limiter, no harmonics will be selected from that amplifier. In another embodiment, Fig. 3 (not shown), the modulator outputs are combined and fed to a common evaluating device; each modulator being fed from respective oscillators one of which is frequency controlled by a phase comparison device to ensure that the modulation outputs have the same frequency and phase.
