Title: Improvements in and relating to means for producing rotary motion of a member about an axis of rotation
Inventor: YOUNG REGINALD
IPC: F16H29/02
Filed: 1958-10-16
Abstract: 899,491. Screwing-up and unscrewing nuts. GENERAL ELECTRIC CO. Ltd. Oct. 13, 1959 [Oct. 16, 1958], No. 33063/58. Class 83 (3). [Also in Group XXIV] A screwing-up device particularly for use with the nuclear reactor controlrod servicing vessel as described in Specification 844,765, comprises a lever. 14 which is oscillated about an axis 6 parallel to the axis of rotation of the member 10 to be screwed up, the lever having pawls 22, 23 pivotally attached thereto which convert the oscillating movements of the lever into rotary movement of the member. The device is secured to a branch 2 of the servicing vessel, and comprises a plate 3 through which extends a bush 5 sealed against gas-pressure in the vessel by a bellows 12, and carrying the pivot 6 for the lever 14. A fork 15 on the lever engages an eccentric 9 on a shaft driven by an electric motor 42 through reduction gearing 44 and a clutch 45, and the other end of the lever carries two pawls 22, 23, either of which may be held in engagement with the cap 10 of the vessel by fluid-pressureoperated pistons 31, the cap being rotated as the lever 14 is oscillated. Rockers 35 are connected to piston-rods 30, and operate microswitches 38, 39, 41, 42, which indicate the position of the pawls. In operation, the servicing- vessel is lowered into position above a controlrod and sealed thereon, the pawls 22, 23 being in their inoperative positions. The vessel is pressurized, and pressure-fluid is supplied to one of the cylinders 32, thus moving piston 31 and spring-urged plunger 26 to the left and engaging pawl 23 with the cap 10. The rocker 35 actuates micro-switch 41 which indicates to the remote operating-position that this pawl is engaged. The lever 14 is now oscillated and the cap 10 is unscrewed, by rotating the eccentric 9, the pawl ratcheting over the serrations on the cap during each oscillation. When the cap is unscrewed, the pressure in cylinder 32 is relieved and the spring 34 moves the pawl 23 to the inoperative position, the rocker 35 then actuating the switch 42. The pawl 22 is used in a similar manner for screwing-up the cap 10. The drive from the motor 42 includes a limitswitch for limiting the torque supplied when screwing-up but allowing full motor-torque to be used when unscrewing. The pawls may have a series of teeth which engage roughened edges on the cap 10.

Title: Improvements in or relating to devices for measuring the rate of motion of a fluid
Inventor: JACOBSON MOSES GAMZU
IPC: G01F1/68
Filed: 1954-11-16
Abstract: 769,465. Electric indicating systems. MINE SAFETY APPLIANCES CO. Nov. 16, 1954, No. 33139/54. Class 40 (1). In a fluid-flow measuring device, a heated negative temperature coefficient resistor connected in a bridge circuit, is disposed in the fluid so that the temperature varies with the flow. The resistor energizing current thus increases with the fluid flow and compensates in part for the loss of overall sensitivity at higher-flow rates. Electrical means to increase the power source to the bridge are also used to compensate for this fall in sensitivity. As shown, Fig. 3, a portion of the fluid flow from a pipe 101 to 109 is diverted by a valve 1021 past the flow-measuring resistor 4 and various compensating resistors 31-34, 70, 71 disposed in a chamber 104, through an orifice 105 to the outflow pipe 109. The resistor 4 and a resistor 1 form two series connected arms of a bridge fed from a battery 60, the remaining bridge arms being formed by the series connected compensating resistors 31-34 and resistors 20, 21, 22 of substantially zero temperature coefficient. The bridge is balanced at zero flow by resistor 22, any fluid flow then reducing the temperature of the heated resistor 4 to upset the bridge balance, the flow being indicated on the meter 50. Resistor 1 compensates for ambient temperature changes and voltage drifts. The resistors 31-34 which are similar to resistor 4 are arranged near the walls inthe chamber 104 where the fluid velocity is much less than in the pipe 103, so as to be substantially unresponsive to fluid flow, and compensate for variations in the temperature of the fluid. A further negative-temperature - coefficient resistor 70 is disposed in the chamber 104 to respond to the fluid flow and is series connected with a resistor 72 across the bridge supply voltage which is measured at 65. A positive temperature coefficient resistor 71 is also disposed in the chamber and connected in series with the battery supply. These resistors 70, 71 both function to increase the voltage supply across the bridge as the fluid flow increases thereby compensating for the decrease in sensivity of the measuring resistor at higher flow rates. For slow rates of fluid-flow the measuring resistor may be located in the main flow but for higher rates it is essential to use the venturi arrangement of Fig. 3. The range of the instrument may also be increased by connecting the battery to the bridge through an amplifier, Fig. 4 (not shown), the amplification factor, varied in accordance with fluid flow by a vane deflected by the flow, varying a capacitor in the amplifier control circuit. The Specification discusses the ratio between surface area and volume of the measuring resistor for optimum response.

Title: Improvements relating to foul detectors for use in bowling alleys
IPC: A63D1/06
Filed: 1962-08-29
Abstract: A photo-electric foul detector for use in a bowling alley comprises a light-sensitive resistor mounted at the bowling end of the alley and illuminated by a beam of light projected across the alley, above the foul line.  The resistor is arranged in series with a relay, and when the beam of light is broken, the relay is de-energized and closes two switches, thereby operating a lamp and an audible signal, and simultaneously energizes a time switch which prolongs the illumination of the lamp after the relay has been re-energized.  A capacitor in parallel with the relay serves to delay de-energization of the latter upon interruption of the light beam and thereby prevents operation of the foul-detector during passage of the ball past the beam.

Title: Improvements in and relating to electrically operated clocks
IPC: G04C3/02
Filed: 1921-12-12
Abstract: 194,407. Johnston, C. F. Dec. 12, 1921. Electric clocks wherein an impulse is given periodically to the pendulum of a master clock through mechanism controlled by an electromagnet and wherein simultaneously electromagnets associated with dials or secondary clocks are energized, have electromagnets with a curved pole piece over which is suspended a curved armature, the two curvatures being such that the air gap diminishes as the armature is swinging over the pole piece to the position of maximum pull and thereafter the air gap increases to prevent the tendency to overswing. The invention also comprises means for resetting the impulse giving apparatus, for the making and breaking of the contacts, and for positively locking the dial or secondary clock ratchet mechanism when the electromagnets are not energized. A gravity lever 2, Fig. 1, is released periodically by means of ratchet-wheel 7 causing the roller 11 to give an impulse to a member 12 attached to the pendulum crutch. In falling, the gravity lever 2 causes contacts 15, 16 to be made to energize the electromagnet 20. The swinging of the armature 19 over the curved pole piece 22 causes the lever 17 to lift the gravity lever, and when the latter is in its original position the lever 17 comes in contact with an ebonite piece 23 and so breaks the electric circuit allowing the armature to resume its original position. The dials are in the same circuit and are provided with similar electromagnets. As shown in Fig. 4, the armature moves a roller 53 and thus causes a lever 54 to swing forward so moving the pallet 58 forward. During this movement, a spring 57 is stressed, which causes the lever to return, release and move the ratchet wheel 50 of the dial. In another arrangement, an additional pivoted lever 63, Fig. 5, is provided which, in co-operation with a roller on the armature arbor, causes a tooth 62 to engage the ratchet wheel when the electromagnet is de-energized and releases the armature.

IPC: H01J29/43
Filed: 1936-12-07
Abstract: 486,548. Cathode ray tubes. WILLIAMS, W. E. Dec. 7, 1936, No. 33489. Drawings to Specification. [Class 39 (i)] A mosaic electrode is formed by depositing metal by evaporation upon a series of wires, e.g. a gauze or grid, through a further series of wires so that the metal deposit extends to the rear surface of the wires. Metal may be deposited from a plate parallel to both series of wires which may be arranged at an angle, e.g. 45‹, with respect to each other. The mesh of the screening wires may be greater than that of the mosaic wires but less than the dimensions of the picture point. The rate of metal evaporation is such that the mean free path is greater than the dimensions of the container. The metal coating deposited decreases in thickness towards the rear surface which may be scanned. The metal may be evaporated from one or more small sources in which case the mean free path is less than the dimensions of the container. In another form, metal is deposited from an elongated source upon a mosaic which consists of parallel wires at right - angles to which are arranged parallel screening wires. The diameters of the wires may be three or four times the distance therebetween. The mosaic wires may consist of, or be coated with, insulating material.

Filed: 1954-11-19
Abstract: 768,285. Chain strainers. EASTERN ROTORCRAFT CORPORATION. Nov. 19, 1954 [Nov. 27, 1953], No. 33548/54. Class 45. [Also in Groups XXV and XXX] A securing device for transferring load from a chain 11 includes a frame, a chain engaging block 17 supported in the frame by a pivot 18 which is transverse to the direction of pull or tension and a latch 22 mounted in the frame in position to hold the block in operative loaded position, the latch being movable to release the block for pivotal movement to a position to disengage the chain, the block incorporating a pocket 35 to accommodate the anchored link. The frame consists of two plates 15 separated by spacers and the block 17 is arranged at one end and a hook 16 is mounted at the other end. The latch 22 is pivotally mounted in the frame and in its operative position engages legs 20 which extend from the block 17. The latch is released by a handle 25. This is freely mounted on the pivot which supports the latch 22 and is slidable in slots 24 in the latch and to permit this the aperture which surrounds its pivot is elongated. The end of the handle engages notches 29 in the frame to hold the latch in its operative position and the handle is kept in this position by a spring 32 one end of which engages the handle and the other end of which engages a secondary latch 30. To release the latch 22 the handle is slid relatively to the latch 22 until its end is free of the notch 29 and the latch 22 can then be pivoted out of the path of the legs 20. To engage the chain the block 17 is provided with a slot 33 through which a link of the chain can be slid sideways. The next link in the chain is received in the pocket 35 underneath the slot 33 and supports the load. This link is prevented from coming out of the pocket by the secondary latch member 30. This member is pivotally mounted on the same pivot as the latch 22 and its movement to its engaged position is limited by flanges which bear on the latch 22. It can be depressed manually against the force of the spring 32 to release the chain but when the chain is to be engaged with the block 17 the entry of the chain into the slot 33 automatically depresses this latch. The hook 16 is slidably mounted in the frame by means of spacers 47 which pass through a slot 39 and it has serrations 40 in each of its edges which are engaged by an internally threaded collar 44. Rotation of this collar by means of a knob 45 moves the hook longitudinally for the purpose of tensioning the chain.

Title: Improvements in potassium soap
IPC: C11D9/00
Filed: 1945-12-12
Abstract: Potassium soaps, particularly those in which more than two-thirds of the fatty acids present are combined with potassium (commercially termed "potash soaps") are manufactured by saponifying triglycerides, fatty acids, or a mixture thereof, with an aqueous solution of potassium hydroxide free from potassium carbonate and keeping the product obtained for some hours at a temperature near to and below its boiling point, if desired, under superatmospheric pressure.  Any potassium carbonate originally present in the potassium hydroxide may be removed by the addition of free fatty acids, after the first stage of saponification and the proportion of potassium hydroxide used may be less than that required for complete saponification.  At least one partial fatty acid ester of a polyvalent aliphatic alcohol, e.g. of glycerol, polyglycerol, ethane diol or butanetetrol may be incorporated in the product obtained by saponification.  The ester may be added as such, e.g. ethane diol monolaurate or butanetetrol monolaurate, or may be formed in situ by partial saponification of a triglyceride.  In an example, 37 kg. of coconut oil was saponified with 18 kg. of carbonate-free 50 per cent potash lye and 44 kg. water.  The product was maintained for some hours just below the boiling point and the water content adjusted so that the molten material immediately solidified when cooled to 30-35 DEG  C.  About 100 kg. of neutral soap were obtained which on the addition of about 10 per cent of water was converted into a thin liquid soap. The presence of partial esters renders the solid soap more unctuous.  The absence of free potassium hydroxide or carbonate from the soaps is said to enable them to retain their initial homogeneous structure on prolonged storage.
