Title: Improvements in or relating to calcium sulphate plaster mixes and to methods of applying the same
IPC: C04B28/16
Filed: 1931-02-04
Abstract: A method of plastering, particularly advantageous in the production of smooth surfaces, consists in spraying a calcium sulphate mix of the accelerated anhydrite type.  This type comprises anhydrous calcium sulphate such as natural or burnt anhydrite or hard burnt gypsum, treated with accelerators such as described in Specifications 236,695 and 317,672, [both in Class 22, Cements &c.].  They may further contain hydrated lime, Portland cement or the like and fillers, pigments, resins or fine pumice.  Preferably the mix is ground to pass at least a 70-80 mesh sieve, it being especially desirable to pass a 200 mesh sieve.  The same production of smooth surfaces may, however, be obtained by incorporating a proportion, e.g. 50 per cent, of a coarse material such as sand, pumice, barytes or cork.

Title: Improvements in radio-telegraphy
IPC: H04L27/10
Filed: 1946-02-05
Abstract: 611,626. Frequency Modulation; automatic tuning correction. BICKLEY, H. D., and COOK, A. Feb. 5, 1946, No. 3600. [Class 40 (v)] In a frequency-shift radio telegraphy system, a superheterodyne receiver is used and the two or more intermediate frequencies are brought to the same frequency by a further heterodyniiig, and are jointly used for automatic correction of the receiver tuning which correction is thus rendered continuous. The received fre-. quencies are heterodyned at a mixer 1 by a local source 13 and the reduced frequencies f1, f2 are passed by a filter 2 to a limiter 3. One frequency, f1, is selected by a filter 4 and passes to the signal converter 6 to register spacing signals. The limiter output also passes to a heterodyne mixer 14 to which the local source 15 supplies a frequency f2-f1. From the output a filter 4a selects the frequency f<1> and feeds it to the signal converter 6 to register marking signals. For the purpose of tuning correction, the output of the limiter 3 is passed to a filter 17 which rejects f2 but passes frequencies around f1 to an amplifier 16, discriminator 9, detector 10 and circuit 11 of short time-constant, to a device 12 for correcting the frequency of the local oscillator 13 during spacing signals. For correcting the frequency during marking signals, frequencies around f1 are selected by a filter 17a from the output of mixer 14, and are fed through an amplifier 16a to the same discriminator 9. Specification 558,260 is referred to.

Title: An exposure device for cameras
Inventor: STREHLE HORSTE
IPC: G03B9/34
Filed: 1963-01-29
Abstract: 990,942. Camera exposure control. PENTAGON DRESDEN KAMERA-UND KINOWERKE VEB. Jan. 29, 1963, No. 3606/63. Heading G2A. In a camera shutter comprising two blinds which run down one after the other, the release mechanism has two cams in fixed relation to each other, the first releasing one blind and the second the other, the exposure-regulating means comprising two escapement levers, either of which, according to the exposure time selected, retards the release of the second blind. In the form shown, the two time-setting discs 2, 3 have mounted beneath them corresponding cams 4, 5, against the edges of which bear respective levers 12, 7. Lever 7, biased by spring 6, has a toothed segment 8 engaging a gear train 10 having an anchor 9. Lever 12, biased by spring 11, has a movable weight 30 fixed to an arm 28. The release member 16 is wound and tenssioned by means not shown, and held against running down by a nose part 17 which latches behind a hooked lever 18. This 'set' position is shown in Fig. 1. The member 16 has an opening 13 into which extends part of either lever 7 or lever 12, according to the setting of the time discs 2, 3; in Fig. 1 it is part of lever 7 which enters into opening 13. Spring-biased into contact with member 16 are two levers 26, 27, which respectively control the release of the two shutter blinds. These are actuated one after the other by two cams 22, 23 fixed to member 16. When the release knob 20 is pressed, lever 18 is disengaged from nose 17, allowing member 16 to run down (anticlockwise). Cam 22 strikes lever 26, so releasing the first shutter blind. After this action, the edge of opening 13 makes contact with the end of lever 7 and begins to turn it clockwise on its pivot, so that its end is being pushed out of the opening 13 (Fig. 2, not shown). During this period the run-down is being retarded by the action of the gear train 10, with which lever 7 engages. After lever 7 has been moved completely out of opening 13 (Fig. 3, not shown) the second cam 23 strikes lever 27 to release the second shutter blind to terminate the exposure. The same manner of operation occurs if the other lever 12 extends into opening 13, except that since this is not engaged with a gear train, it has a slidable weight 30 which acts as an escapement force.

Title: Arrangement for the transmission of call and selector impulses over telephone lines
IPC: H04Q1/48
Filed: 1932-02-08
Abstract: 396,719. Automatic exchange systems TELEFONAKTIEBOLAGET L. M. ERICS. SON, 33, Kungsgatan, Stockholm. Feb.. 8, 1932, No. 3698. Convention date, Feb. 11, 1931. [Class 40 (iv).] In the impulsing arrangement shown ir Fig. 1, in which the impulse sender 1 control: a relay 2 to produce current reversals which are applied to the line L through a transformer T, two preliminary impulses are gener. ated due to the initial closure of the primary circuit and of the circuit of relay 2, and a final impulse is generated on release. In some case; these impulses may be utilized, but where it is desirable to prevent application of any of them to the line, a relay 9 is provided to short-circuit the secondary circuit of the transformer T for suitable periods. A more specific embodiment of the invention is shown in Fig. 3. When the calling loop is closed, polarized relay PR2 energizes, followed by relays TR2, SR. Relay RU operates in parallel with relay GY3 and transmits a calling impulse through the transformers T1, T2, while relay VR2 pulls up slowly and opens the circuit of relays RU, GY3. Relay GY3 relapses more quickly than relay RU, and thus relays GY1, GY2 operate for a short period and short-circuit the windings of the transformers T1, T2. Impulses are repeated by relays PR2, IR2, SR as reversals in the primary circuit of the transformers T1, T2, relays VR2, RU, GY3, GY5 being maintained during each train, the last relay serving to improve the impulse circuit. An extra impulse generated at the end of each train is absorbed due to the momentary operation of relays GY1, GY2 as described above. When the called subscriber replies, an incoming impulse operates relay PR1 which connects up relays IR1, VR1, GY4, thus removing a short-circuit from the secondary windings of the transformers T3, T4 and completing a lowresistance talking circuit.

Title: Improvements in and relating to machines for winding cones of yarn
IPC: B65H54/10
Filed: 1937-02-09
Abstract: 490,363. Winding yarns. SCRAGG, E. R., SCRAGG, T. W., and DAVENPORT, A. Feb. 9, 1937, No. 3783. [Class 120 (ii)] A machine for winding yarn on to a cone 10 has the winding spiral shaft 9 set at an angle to a hollow shaft 6 carrying a cone 8 having a frictional ring 8a engaging a cone 12 on the shaft 9, and the cone 8 is driven and slidable along a bar 5 carrying the shaft 10 so that, at the start of winding, the ring 8a engages the base of the cone 12 so as to give a slow start and then automatically moves along the cone 12 to give a gradual speeding up of the winding spindle and thereafter being gradually moved back to the base of the cone 12 so as to reduce the speed of the winding spindle as the package wound on the cone 10 increases in diameter and to give a slow finishing speed. The shaft 6 carries a wide driving pulley 7 and the winding spindle 9 is geared to the shaft 21 carrying a cam 20 for traversing the yarn guide 15 which is mounted in a slotted rod 18 carried by counterweighted arms 17 oscillatable on the shaft 21. The rod 18 carries an arm 19 having a ball 20 engaging the cone 8 and after the ring 8a has moved to the small end of the cone 12 to drive the spindle 9 at its maximum speed, the movement of the thread guide away from the spindle 9, as winding proceeds, moves the rod 18 and arm 19 and so pushes the cone 8 back along the bar 5 to reduce gradually the speed of the spindle 9. The bar 5 is carried by a support 5a pivoted on a rod 5b and having a projecting arm 5c which is disposed adjacent an arm 35 on a rod 31 which can be moved by a handle 32 against the action of a spring 33 surrounding the rod so that a hook 30 on the rod engages a hook 29 on a curved arm 22 pivoted in the machine frame and carrying a pivoted yam guide 13. The yarn guide 13 carries an arm 23 which, if the yarn breaks, moves into the path of a toothed wheel 24 on the shaft 21 and is moved thereby to lift the arm 22 and disengage the hook 29 from the hook 30 ; the spring 33 then rotates the rod 31 to move a brake shoe 34 thereon into contact with a brake drum 12a on the spindle 9 and the arm 35 into contact with the arm 5c so as to tilt the support 5a and move the cone 8 out of engagement with the cone 12. The slide carrying the thread guide 15 has an arm 26 pivoted thereto and held in engagement with the underside of the arm 22 by a spring 27 pressing against a thumb release piece 28 so that as the thread guide moves outwards, the counterweight 17a cannot move it back towards the winding spindle until the piece 28 is released.

Abstract: 1,084,952. Regulating fluid flow. PYE Ltd. Jan.20, 1965 [Jan. 31, 1964], No.4100/64. Heading G3H. [Also in Division F2] The pressure of gas flowing to a chromatographic column is adjusted by a pressure regulator PR, Fig. 1, and the desired flow-rate is set by a dial D which adjusts a cam C connected to a variable restriction V. Upon closing a switch S an electric motor M is energized to rotate the cam C through gearing GB; when the maximum flow-rate is attained a stop X opens a microswitch MS to de-energize the motor so providing a constant flow-rate. If the stop X is positioned clear of the micro-switch or a further stop is provided, a cyclic change of flow-rate results. A pressure controller DP is disposed downstream of the restriction. The restriction may take the form of a piston 2 Fig. 3 (not shown), with a tapered flat F and restricted inlet and outlet ducts Dl, D2; a third duct D3 is provided so that a constant-pressure gas urges a piston roller 3 against the cam C, Fig. 1. Another form of restriction, is comprised by a cylindrical rod 7 Fig. 4 (not shown), with a flat F coacting with a duct D2, the rod depending from a carrier 8 the rod end of which has a sealing ring 11 to fully close-off the duct D2. The carrier 8 is coupled to a piston 2 through a ball 13 and a loading spring 10. The device may be used to control flow to a chromatographic column in which the carrier is a liquid; in this case the restriction has one inlet sequentially connected to each one of a series of outlets of gradually varying flow-resistance.
