Patent GB-698533-A (GB)
Title: Improvements in or relating to radar and other systems employing cathode ray tubes
Inventor: SHIPWAY ROGER PROWSE
IPC: H04N3/26
Filed: 1951-11-16
Abstract: 698,533. Cathode-ray tube circuits. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. July 23, 1952 [Nov. 16, 1951], No. 26991/51. Class 37. [Also in Group XL (c)] In order to prevent damage to the screen of a radar P.P.I. cathode-ray tube when the rate of aerial rotation falls below a predetermined value, means are provided for automatically reducing the intensity of the cathode-ray beam. The invention is described as applied to a system in which a Selsyn transmitter ganged to the aerial is coupled to a Selsyn receiver S1-S3 controlling the angular position of the timebase. As shown, one stator S2 is coupled to an infinite impedance detector V8 giving a unidirectional voltage output varying at twice the Selsyn rotation rate and the A.C. component thereof is detected by diode 17 giving a negative D.C. voltage which is applied to valve 21 with a relay coil 22 in the anode circuit, the system being such that for normal aerial rotation speeds V21 is biased off but at low speeds it becomes conductive thereby energizing relay coil 22 to operate contacts which reduce the beam intensity by controlling (1) the bias on the grid of the cathode-ray tube, (2) the amplitude of the video signal or (3) the bias on the video amplifier or by changing a load resistance. In a modification, Fig. 3 (not shown), the cathode of diode 17 and the lower end of its load resistance 13 are connected to a point of low positive potential, e.g. 7v, thereby permitting large values for filter components 15, 16 in the grid circuit of V21.

Patent GB-913176-A (GB)
Title: Improvements in and relating to evaporation
IPC: B01D1/10
Filed: 1960-08-04
Abstract: <PICT:0913176/III/1> Aqueous solutions of organic solids, such as whey, are concentrated by passing the solution through an inverted U-tube heated in a steam-chamber 1, one upright portion 2 of the tube being connected to the feed-container 13, the rate at which heat is supplied to the solution and the length and diameter of the upright portion of the tube being such that the solution boils and is raised to the top and through the horizontal portion 3 of the tube by the lifting-action of the steam evolved from the solution. The concentration is completed in the downwardly-extending portion 4 of the tube; and the mixture of concentrated solution and steam enters separator 6, from which the concentrated liquid is withdrawn by pump 8.  It is possible to further concentrate whey containing 55% by weight of dry substance to produce a bright yellow liquid containing 85% by weight of dry substance.  This yellow liquid subsequently solidifies to a solid mass.  The U-tube may be made of glass, and observation windows may be provided in the steam-chamber.  The steam leaving the separator is condensed in condenser 10.

Title: Improvements in or relating to high speed electric circuit breakers
IPC: H01H71/68
Filed: 1936-10-08
Abstract: 482,752. Automatic circuit-breakers. WHIPP & BOURNE, Ltd., and WHIPP, F. Oct. 8, 1936, No. 27291. [Class 38 (v)] A high-speed circuit-breaker comprises a pair of contacts 10, 11 which, on movement of the handle 20 or operation of the closing solenoid 21, are relatively displaced towards each other by an amount insufficient to close the circuit until a detent 16 becomes operative to maintain the contact 10 in its closed position, the closure of the circuit being completed under the control of a spring 34 during the return movement of the handle or on de-energization of the solenoid. The contact 10 is carried on one arm of a bellcrank lever 13 pivoted at 14 and is moved to its closed position by means of toggle levers 23, 22, one of which is pivoted at 27 while the other carries a roller 31 adapted to engage a shoulder 32 on the bell-crank lever 13. The upper toggle lever 22 is connected by a link 24 to a bell-crank lever 25 pivoted at 48, the two bellcrank levers being connected together by the spring 34. The bell-crank lever 25 is connected by a link 26 to an arm 18 carrying the contact 11. When the handle or solenoid 21 are operated in the closing direction, the bellcrank lever 13 is moved by the roller 31 until the detent 16 passes beneath a pin 47 on one arm of the bell-crank lever 13 ; during this movement the link 24 engages a shoulder 49 on the bell-crank lever 25 and rotates this in a counterclockwise direction, so that the contact 11 moves away from the contact 10. On reverse operation of the handle or solenoid, the bell-crank lever 13 is held by the detent, and the spring 34 rotates the bell-crank lever 25 in a clockwise direction and causes the collapse of the toggle 22, 23, and simultaneously moves the contact 11 into engagement with the contact 10. The detent 16 is tripped on overload by a rod 38 connected to the core of an overload coil 37. A magnetic blow-out coil 44 with polepieces 46 and an arc-shoot 40 is provided. The core of the coil 44 may be arranged to attract the contact 11 and open the circuit more quickly than the overload coil 37 can operate, on heavy overloads.

Title: Improvements in or relating to the formation of loops of string
IPC: B31D1/02

Abstract: 452,687. String - tagging machines. DENNISON - VICTOR CO., Ltd., Minerva Road, Park Royal, London.-(Dennison Manufacturing Co.; Howard Street, Framingham, Massachusetts, U.S.A.) Oct. 4, 1935, No. 27448. [Class 43] [See also Group XV] A machine for making loops of string having their ends secured by a metal tube, the strings being, if desired, threaded through labels, consists of means for feeding the string from a supply, forming loops therein, and laying the ends of the loops in a channel formed from a metal strip fed to the machine, the channel being subsequently closed to grip the string ; when labels are applied, the latter are fed singly from a stack through which the string is initially threaded, each separated label lying in the bight of the loop. Fig. 9 shows the stack of labels contained in a magazine M, the string C passing through holes therein from a supply reel. A reciprocating slide S pushes the labels singly to the position T<1> and a reciprocating loop former L carries the string to lie in the recess 11, Fig. 13, in the die I<1>. The strip W is fed by ratchet-operated feeding wheels R, R<1>, the latter being carried in a spring- influenced eccentric bearing, and is initially bent to channel form by dies D, D<1>, Fig. 10. The dies D, I<1> are carried by a reciprocating head 5 and effect the bending of the strip to channel form and the clinching of the channel round the string in stages. The strip may be severed by a knife K and the loops hang between guiding members G. When labels are not attached, the magazine is dispensed with and the loops are formed by hook members on the slide S.

Abstract: 505,891. Grinding; milling. ROWLAND & CO., Ltd., F. E., and TAYLOR, H. Oct. '13,1937, No. 27773. [Class 60] [Also in Group XXII] A grinding, polishing, milling, or other machine comprises a bed 1 upon which are slidably mounted two headstocks 4, 5 acted upon by weights 23, each headstock being adjustable by rack and worm gearing 6 .. 9 operated by a hand wheel 10. Slidably mounted on each headstock is a housing 11 in which is mounted, in ball bearings 12, a spindle 13 carrying a grinding-wheel or other tool 14, each spindle being belt driven from a pulley 16 on the respective end of a main shaft 2. Each housing has thereon a lug 11a in which is pivoted a lever 17 adjustably carrying a weight 18 and having an arm bearing against the respective headstock, the housing thus being urged outwards to hold a projection 20 thereon against the upper end of a lever 19 pivoted to the headstock. The other end of each lever rests on an elongated eccentric 21 on a shaft 22, the two shafts 22 being aligned and each carrying a sprocket 26 to which one end of a chain 27 is connected, the other ends of the respective'chains being secured to a lever 28 pivotally connected at its centre to a treadle 29. Depression of the treadle thus moves the housings 11, the movement being independent of the adjustment of the headstocks, and the lever arrangement 28 ensuring that if one wheel 14 contacts with the work, which is mounted by a vice &c. between the wheels, before the other wheel, this latter will move more rapidly to grinding position. Stops 32 on the headstocks are adjusted so that the required movement of the wheels &c. 14 has taken place when the stops are engaged by brackets 33 on the housings 11. One only of the headstocks may be adjustable, the chain and lever device 27, 28 may be replaced by differential gearing, and the levers 19 and eccentrics 21 may be replaced by rotary mechanism; more than two wheels &c. 14 may be employed. According to the Provisional Specification, the headstocks may be integral with, or permanently attached to the bed.
