Abstract: 412,346. Cycle brakes. WHITMILL, W. H., 8, Coniston Road, Earlsdon, Coventry. March 3, 1933, No. 6484. [Class 136 (i).] In a rim brake for cycles, a U-shaped applying-member is formed of pivoted limbs, which are guided by parts interfitting therewith, one of the interfitting members being of channel section for this purpose. In the form shown, the U-shaped applying-member is formed of two limbs 2 of channel section pivotally connected together by means of hook-shaped ends 3, Fig. 2, having openings 4 to fit into grooves 5 in a cylindrical block 6, which is adapted for the connection of Bowden mechanism as by means of a tapped hole 7 to receive a hollow adjusting- screw 8 for the outer casing 9. The lower ends of the limbs 2 are pivoted at 10 to forked bellcrank levers 11, which carry the brake blocks and are pivoted on pins 12 projecting from supports 13 clipped to the cycle frame 14. On the supports 13 and between the forked parts of the bell-crank levers 11 are mounted curved sheet-metal &c. arms 15, which act as guides for the limbs 2. The arms 15 may be pivoted together at 17 to allow of adjustment to suit wheels of different widths, and are connected to the inner cable 18 of the Bowden mechanism, the brake being applied by downward movement of the limbs 2 under the action of the Bowden casing 9. In a modification, the guiding-arms 15 are formed in one piece with outwardly-opening channels to guide plain limbs 2 of the applying-member, which are given an upward pull by the Bowden cable to apply the brake. Specifications 412,373 and 412,379 are referred to.

Title: Improvements in machines for filling bottles and other containers
IPC: B67C3/16
Filed: 1940-04-10
Abstract: 540,305. Valves. CROWN CORK & SEAL CO., Inc. April 10, 1940, No. 6512. Convention date, June 29, 1939. [Class 135] [Also in Group XVII] A machine for filling milk bottles &c. has a reservoir 10, Fig. 1 rotatable on a base, a liquid inlet pipe 36, extending into and rotating with the reservoir and a horizontally extending floatoperated sleeve valve 61 mounted on the lower end of the inlet pipe and rotating with it. The domed base 14 of the tank 10 carries a skirt 15 which bears on the flange 16 of a rotary shaft 17. The use of seams or joints in the base 14 is avoided. The filling system maintains sub-atmospheric pressure above the surface of the milk in the tank 10. Air is drawn through venting tubes 19 and dripping of milk from the filling valves 18 is thereby prevented. Each tube 19 has ribs 20, Fig. 2, shouldered at 21 which support the tube 19 in a shell 22 depending from the valve aperture 24. A resilient valve or sealing ring 25 secured to the lower end of each shell 22 co-operates with a sealing surface 26 on each tube 19 to form a seal which will be broken when the mouth of the bottle to be filled forces the lower portion of the ring 25 away from the surface 26. Milk is delivered to the tank 10 through stationary pipes 30, 32. Pipe 32 has a sliding fit in the pipe 36 which rotates with the tank and is supported in a boss 37 fixed to the cover 39 of the tank. A removable gland nut 40 maintains a sealed joint. The side walls of the boss 37 are apertured at 41 to connect with a vacuum pump. The apertures open into a chamber 43 which has a ground or seat fit upon the upper side surfaces of the boss 37 so that the boss 37 may rotate while the chamber remains stationary. There is an air-tight seal 50 between the tank 10 and the cover 39, which has one or more hand holes 52 normally closed by cbver plates 53. The vent tubes 19 may be taken out through the holes 52 if necessary. The flow of milk through the pipe 36 into the tank is regulated by a float valve 55 mounted on a casing 56 with a horizontal bore 57. The casing extends laterally of pipe 36 and the extended portion has a series of slots 60. A slotted valve sleeve 61 rotatable under the influence of a float is seated on the extended portion. The ends of the horizontal bore of the casing 56 are closed by plates 70, 71, held in place by a resilient clamp 73. When the clamp 73 is removed, the parts of the float valve may be taken.apart for cleaning.

Abstract: 393,384. Envelopes. MEATCHEM, C. A., 39, Rob Lane, Newton-le-Willows, Lancashire. March 5, 1932, No. 6698. [Class 146 (ii).] In an envelope or like container for flat or thin articles and having a single opening, the mouth is shaped to facilitate the insertion of an article by cutting away the portion of the margin which lies towards one side of the centre of the mouth, and cutting away the oppositely disposed portion of the other margin of the mouth, no part of each uncut margin extending upwardly beyond the adjacent sde of the mouth to a greater extent than does a part nearer to the centre of the mouth than to the adjacent side of the envelope.

Title: Continuous wave radar apparatus for distance measurement
IPC: G01S13/32
Filed: 1973-02-12
Abstract: 1365059 CW radar CONSTRUCTIONS NAVALES ET INDUSTRIELLES DE LA MEDITERRANEE 12 Feb 1973 [10 Feb 1972] 6720/73 Heading H4D A CW radar includes two threshold trigger circuits responding to different levels of rectified output voltage from the radar receiver, a first counter started and stopped by the successive responses from the two threshold circuits and which counts impulses produced from the receiver output voltage and computing means for determining from the count, the value of the receiver output voltage corresponding to a given target range. Reflections of the radar transmissions from a target set up a standing wave pattern and as the target approaches, the receiver output amplitude oscillates with a period equal to one-half the radar wavelength. The envelope of the oscillation also reduces with range due to the fourth power low, Fig. 2. The actual amplitude of the variation is unknown since the radar cross-section of the target may vary giving curves 3, 4; 3<SP>1</SP>, 4<SP>1</SP>; 3<SP>11</SP>, 4<SP>11</SP>. However by measuring the number of halfwavelengths n between points at which the envelope crosses known levels V 1 , V 2 , the receiver output amplitude for any range can be predicted. In a proximity fuze, Fig. 3 the critical range D 0  is known and the receiver output at which this occurs is given by where a = 4#V 2 /V 1  The receiver 5 output is fed to threshold triggers B 1  and B 2  operating at V 1  and V 2 . These provide start and stop pulses for counter 9 which counts the number of cycles in the receiver output fluctuation by counting the number of pulses from bi-stable T connected to the receiver output. When B 2  is triggered counter 10 contains a value n which is raised to the fourth power and fed to one input of comparator 15, which is enabled by the B 2  output. The second input to the comparator comes from an A/D converter 13 which receives a signal equal to the receiver output amplitude divided by b. When the comparator inputs are equal, the receiver output has reached V 0  and an output 18 is produced which detonates the missile. In a completely digital version (Fig. 4, not shown) the number of half wavelengths N between D 1  and D 0  is calculated from the formula q = a/a-1 is arranged to be a multiple of 2. In this case two counters count the output from the bi-stable T. The first does so continuously from the triggering of B 1  and the second counts n as before. n is multiplied by q by shifting digits and D 0  is subtracted. These two numbers form the inputs to a comparator which triggers the fuze when they are equal. If the target range is to be displayed, the output of the first counter is subtracted from q . n and the result fed to an indicator.

Filed: 1965-02-17
Abstract: 1,028,660. Random access stores. NATIONAL CASH REGISTER CO. Feb. 17, 1965 [April 16, 1964], No. 6863/65. Heading G4M. In a card random access memory of the type disclosed in Specification 889,788, a retaining member 44 delays release of a record strip 12 adjacent to magazine loader plate 40 until a previously selected record strip has returned to the magazine 19. Member 44 prevents the strip 12 adjacent plate 40 from dropping after it has been released by the selector and side release rods so that when plate 40 is moved out to receive a returning strip, there is no tendency for the adjacent strip 12 to move out with plate 40 and thus interfere with the return of the other strip. A strip returning to the magazine is detected by a photo-cell 30 which initiates actuation of loader plate 40, and, after a delay (one shot 105) momentarily operates member 44 to allow release of the adjacent strip 12 if it has been selected. The logic circuit 116 (Fig. 10, not shown) causes the following operations to be performed: (a) When a new set of strips is inserted in magazine 19, no strip is engaged by member 44, and although the selector rods are actuated when computer 115 calls for a second strip, the side release rods are not actuated (signal U) until the first strip selected has returned to the magazine. (b) Circuit 116 includes a register and comparator for detecting when two successive selected strips are in fact the same strip, and in this case the side release rods are actuated without the above delay and member 44 is retracted (flip-flop 101 and AND gate 158) so that the returning strip is dropped immediately after entering the loading device. The system then has to wait as in (a) until this strip has returned to the magazine because no strip is engaged by member 44. (e) When the strip nearest plate 40 is engaged by member 44, actuation of the side release rods is not delayed until the system is free of moving strips, and release of a selected strip is not delayed unless the strip selected happens to be that engaged by member 44.
