Patent GB-815942-A (GB)
Title: Tank construction
Inventor: DOBELL CURZON
IPC: E04H7/20
Filed: 1957-01-24
Abstract: 815,942. Tanks. PRELOAD CO. Inc. Jan. 24, 1957, No. 2638/57. Class 69 (1). A concrete structure 20 for containing fluids comprises a base 22, an endless prestressed side wall 24 mounted thereon but spaced from the base by a resilient pad 32 of width less than the width of the side wall to permit relative movement between the side wall and the base. A dome 26 may be mounted on the side wall similarly separated therefrom by an elastic pad 32a. In constructing the tank an endless connector 30 is inserted in the base 22 before the concrete sets. A rubber pad 32 is then laid in place and a level base of clay 38, 40 (Fig. 2) is built up on each side of the pad 32 to provide a level bottom surface edge for the side wall. The clay 38, 40 is covered with a paper separator 42. The walls 24 are formed by pouring concrete into a shuttering 44, the upper end of the endless connector being attached by wire 46 to a ring 48 at intervals. The endless connector 30 is made of rubber and prevents fluid leakage from the structure. The rubber pads may be continuous or formed of small intermittent pads. The pad 32 is as narrow as possible consistent with supporting the superimposed load. After the concrete of the wall has set the clay sections 38, 40 are flushed out and the wall is then prestressed by means of wires 36 received in recesses 34 in the walls 24. In a modification shown in Fig. 4, the base is provided with an elevated peripheral step 50 and the side wall is formed with a protrusion 52 which overlaps the step 50 to provide a key which will ensure that the tank stays on its base during earthquakes or other shocks. A copper water stop may be substituted for the resilient water stops 30, 130. The dome 26 is mounted on the side wall 24, in a similar manner to the mounting of the side walls on the base, an endless connector 30a and pad 32a being used. As shown in Fig. 6, bolts 64 are set in the side walls. Bonding of the bolts to the concrete is prevented by coating the bolts with a heavy bituminous cover and then further covering them with a pipe sleeve 66 the inside of which has also been coated with a bituminous cover.

Title: Improvements relating to slicing machines
IPC: B26D7/01
Filed: 1935-01-26
Abstract: 449,696. Slicing-machines. BERKEL & PARNALL'S SLICING MACHINE MANUFACTURING CO., Ltd., Aden Road, Ponders End, Middlesex.-(Maatschappij van Berkel's Patent Naamlooze Vennootschap ; 33, Boezemsingel, Rotterdam, Holland) Jan. 26, 1935, Nos. 2656 and 10715. [Class 28 ii)] In a slicing-machine, the substance is slid towards the cutting plane, over a support 22, Fig. 1, and is positioned between a fixed side wall 23 and a laterally adjustable member 24 which is supported by an arm 26 which extends above and across the substance. The member 24 is prevented from pivoting about the arm 26 by an auxiliary parallel arm which is engaged by a fork on the sleeve 35, the main arm 26 and the auxiliary arm being joined by a bridge 40. The member 24 is releasably clutched to the arm 26 by a tilting ring 37. The arm 25, carrying the main and auxiliary arms, is pivotally mounted on a shaft 28, screw-means operated by a handwheel 32 being provided to lock the arm 25 in any desired angular position. The member 24 may be pivoted to the sleeve 35 and pressed towards the wall 23 by a spring. In the modification shown in plan in Fig. 7, the main and auxiliary arms 61, 62 are tubular and are clamped between top and bottom parts of a casing 64 which is secured to an arm corresponding with the arm 25, Fig. 1, by a screw 67. Screws 66 secure the casing parts together. A pulley is arranged within the casing 64, journalled on the screw 67, and a coil spring 74 passes around the pulley, into the tubes 61, 62, one end of the spring being anchored at 73 whilst the other end is attached to a pin 75 on the sleeve 70 which carries the member corresponding with the member 24, Fig. 1. The pin 75 slides in a longitudinal slot in the tube 61. A latch 76 under the action of a spring 78, engages a pin 80 on the bridge piece 72, when the retention of the member 24 in a retracted position is desired. When the latch is released, the member 24 moves against the substance and is pressed resiliently against it during the feed. The arms 61, 62 are swung about the pivot 67 to an inoperative position when the substance is to be handled. The spring 74 may be replaced by a volute or flat spiral spring, the inner end of which is anchored to the pivot bolt 67 and the free end to the pin 75.

Title: Improvements in driving means for motorised cycles
IPC: F16H61/662
Filed: 1958-01-27
Abstract: 847,415. Expanding wheel and change-speed chain gearing. UHER, E. Jan. 27, 1958 [Feb. 2, 1957], No. 2668/58. Addition to 830,275. Class 80 (2). [Also in Group XXXI] An improvement in or modification of the invention of the parent Specification consists in providing a V-belt gear for the automatic change of transmission, which gear comprises a V-belt driving-pulley 4, 6 and a V-belt driven pulley 20, 22 in which the axially-displaceable half-pulleys are loaded in the direction of their approach by springs 10, 23, respectively, the spring 23 being the stronger, a centrifugal weight arrangement 8 which counteracts the spring loading being provided on the driven pulley. As soon as the driving pulleys are set in motion at a higher speed, the pivotallymounted weights 8 are swung outwardly under the action of centrifugal force, projections 9 from the weights displace the half-pulley 22 axially against the action of the spring 23 and away from the other half-pulley 20 so that the V-belt is caused to run on a smaller radius by the action of the spring 10 between the driven pulley halves and correspondingly on a larger radius between the driving pulley halves, the reduction ratio thus being reduced in proportion to the speed.

Abstract: 583,893. Lathe drivers ; chucks. AKT.-GES. DER EISEN -UND STAHLWERKE VORM. G. FISCHER. Feb. 14, 1944,. No. 2731. Convention date, Feb. 15, 1943. [Class 83 (iii)] A lathe driver comprises three cam members 8 rotatably mounted on pins 7 carried by a ring 5 floatingly mounted in a recess in a ring 2 secured to the spindle (not shown) and to a casing 19 and having upstanding pins 3 engaging in slots 10 in the members 8, the centres of gravity 11 of the members 8 being so positioned that on rotation of the driver, centrifugal force imparts to the ring 5 a rotational component opposite to the direction of rotation of the housing, thereby causing the jaw portions 9 of the members 8 to grip the work 12. The ring 5 is retained against axial movement by guide discs 6 and against too great a rotational movement relatively to the housing by lugs 13. Centring pins 14 loaded by springs 15 act on the periphery of the ring 5, or alternatively may act on a ring forming the outer race for balls running in a groove in the periphery of the ring 5. A spiral spring 20 may be secured between the ring 5 and the casing 19 so as to assist the closing of the jaws. Alternatively, if the driver is to be rotated at a high speed, the spring may be arranged so that when at rest it acts to open the jaws, its action being counteracted by centrifugal force when the housing is being driven.

Filed: 1956-01-27
Abstract: 799,359. Washing machines. HORSCROFT PROPRIETARY, Ltd., L. Jan. 30, 1957 [Jan. 27, 1956], No. 2776/56. Class 138 (2). A timing device for controlling the operation of a washing or dry-cleaning machine consists of a pendulum 3 which is pivoted at 4, disposed in the path of a striker 8 on a reversible final drive gear wheel 9 the direction of rotation of which is automatically reversed at appropriate periods according to a predetermined sequence, a pawl 5 attached to the pendulum slightly above its pivot point, which engages with ratchet wheel 6 mounted on shaft 7 carrying cams 7a for operating switches or valves, and two spring- loaded balls 10 arranged on either side of the pendulum to prevent its swinging past its dead centre position until forced to do so by the action of striker 8. When the gear wheel 9 rotates in an anticlockwise direction, the pendulum assumes the left-hand position shown in broken lines and the pawl moves idly over the teeth on ratchet wheel 6; the pendulum then returns to the position to the left of the dead centre position. When the motion of gear wheel 9 is reversed, the pendulum is forced past the spring-loaded balls 10 and assumes the righthand position shown in broken lines and in doing so causes the pawl 5 to move ratchet wheel 6 through an arc corresponding to one tooth after which the pawl idles until the direction of rotation of gear wheel 9 is reversed again. The lower end 14 of pendulum 3 can slide upwards in lugs 15 to prevent a longitudinal thrust from being exerted on the pendulum by striker 8.

IPC: H02K17/38
Filed: 1928-01-31
Abstract: 285,056. Siemens - Schuckertwerke Akt.-Ges., (Assignees of Siemens-Schuckertwerke Ges.). Feb. 10, 1927, [Convention date]. Alternating - current induction machines.- In an arrangement for driving a reciprocating machine, such as a pump or compressor, by a synchronous motor the motor is cascaded, with a commutator machine excited in known manner as described, for example, in Specification 283,957 so that it introduces into the secondary side of the motor two voltages, one of which is proportional and opposed to the slip of the motor and cancels its secondary voltage, while the second is independent of the slip and generates the loading current in the secondary of the motor. In the arrangement shown, the synchronous motor 1, which drives a compressor 3, is cascaded with a commutator machine 2 rotor-excited bv two voltages, one from a line transformer 14 and one from a commutator stator-fed shunt machine 12 mechanically coupled to the motor 1. The first component is constant and the second is zero at synchronism and increases in proportion to the slip, the result being that the current in the rotor of the motor 1 is independent of slip and a constant output from the motor is obtained without the transmission of power fluctuations to the supply mains. By regulating the transformer 14, the output of the motor 1 may be adjusted to the demand of the compressor.

Title: Production of artificial speech
IPC: G10L25/00
Filed: 1941-03-07
Abstract: 543,239. Producing artificial speech. STANDARD TELEPHONES & CABLES, Ltd. March 7, 1941, No. 3108. Convention date, March 16, 1940. [Class 40 (iv] Artificial speech is produced from a loudspeaker 19 with the aid of a key II which connects up a noisesource or a relaxation oscillator according as an unvoiced or a voiced sound is to be reproduced, a key I which controls the fundamental frequency of the relaxation oscillator, keys III, IV which control the tuning of two circuits which correspond to the two resonant chambers into which the mouth cavity is divided by the tongue and a key V by which a sudden drop in the output can be produced to give the effect of a stop-consonant. The tuned circuits may be controlled by varying a direct current through the inductances, by adjusting the tapping point on the inductance or by connecting up alternative condensers. In a modification, Fig. 2 (not shown), the keys III and IV are coupled together and the functions of the keys I, II are performed by a single key. The key V is omitted since it is possible to produce its effect by suitable manipulation of the single key. In a further modification, Fig. 3, the stop-consonant effect is produced by a key V<SP>1</SP> which connects up in turn the normal output from the variably tuned circuits, the output of a fixed tuned circuit 45 fed by the relaxation oscillator, the output of the variably tuned circuits modified by passage through an additional fixed tuned circuit 46 and the output of a fixed tuned circuit 47 fed from the noise source. If fully depressed, the key contact returns to normal by an alternative path in which it connects up the normal output. In another modification, Fig. 4 (not shown), separate tunable circuits are provided for the voiced and unvoiced sounds. Specification 466,327 is referred to.

Abstract: 117,804. Stewart - Warner Speedo - meter Co., (Assignees of Duffy, T. I.). June 19, 1917, [Convention date]. Electric - l a m p lanterns.-In a lantern, a lamp socket is adjustable with reference to a reflector or the like by means of a cam bearing on the socket and spring conductors pressing the lamp in the opposite direction. As shown, the bayonet - slotted socket 13 slides in a non-conducting sleeve 6. Contact springs 19 attached by screws 25 to the outside of the sleeve pass through slots in the sleeve and socket into engagement with the lamp-cap. A lug 14 on the socket slides in a guide-groove in the sleeve, and a tongue near the other end of the socket rests against a cam surface struck up around the inner edge of a flat ring 20. A notch in the ring allows it to pass over the tongue in assembling, subsequent rotation of the ring being restricted by curved slots 22 and screws which serve to secure the ring after adjustment. These screws enter a flange at the back of the sleeve 6. Between the flange and three ribs on the outside of the sleeve is mounted a flat switch ring 31 provided with a handle 34 and a tongue 29 for engagement with one of the contact springs 19 or in a recess in the sleeve in the " off " position. One of the wires is attached to the tongue, and the other is held by the screw 25 which secures one contact spring 19. Notches allow the ring to pass over the ribs in assembling, while a slot through which the handle passes out of the casing prevents subsequent removal of the ring. The inner edge of the reflector is corrugated and is gripped by a flange on a ring 8 having lugs secured to the ribs on the insulating-sleeve.
