Title: Hydraulic master cylinder device
IPC: B60T11/20
Filed: 1962-04-25
Abstract: 1,009,391. Hydraulic brakes; seals. BENDIX CORPORATION. April 25, 1962 [June 7, 1961], No. 15673/62. Headings F2B and F2F. In a tandem master cylinder for hydraulic braking systems of vehicles having a piston 30 mounted in the cylinder bore and another piston 32 disposed rearwardly of the piston 30, and adjustable abutment connection is formed by a threaded stem 58 screwed into the piston 30 the head of which bears against a sleeve 54 bearing against the piston 32 by means of a spring member 52. The piston 32 is directly applied by the operator through a linkage system and the chamber formed between piston 32 and piston 30 leads to one set of brakes, the chamber ahead of piston 30 leading to another set of brakes. The reservoir 12 of the master cylinder is provided with a partition 14 extending in a plane transverse to the direction of the vehicle movement and includes a portion sloped towards the rear end of the vehicle to prevent fluid being transferred from compartment 18 to compartment 16 when the vehicle decelerates. A packing gland 46 is positioned between the cylindrical surfaces of the cylinder bore and the piston 32 and comprises an annular sleeve retained in the cylinder bore and having spaced annular grooves 48 formed in its inner and outer surfaces and sealing rings placed in the grooves. The sealing rings in the inner grooves of the packing gland 46 have a sealing lip engaging the surface of the piston 32. Should there be an hydraulic failure of the system associated with the front wheel brakes the two pistons 30, 32 will move together towards the left until the end 70 of piston' 30 engages a stop 68. Thereafter piston 32 will move towards the left against the resistance of the caged spring 52 and the sleeve 54 slides along the length of the stem 58 to create pressure in the chamber between the pistons leading to the rear wheel brakes. Should there by an hydraulic failure in the system associated with the rear wheel brakes the piston 32 acting through the spring 52 will displace piston 30 to the left and communicate pressure from the chamber ahead of piston 30 to the front wheel brakes. Reference has been directed by the Comptroller to Specification 941,340.

Abstract: 890,741. Ionisation chambers. MULLARD Ltd. March 4, 1958 [May 20, 1957], No. 16011/57. Class 39(1) [Also in Group XL(b)] In a radiation meter of the ionization chamber type which provides a logarithmic indication of radiation intensity, the chamber is divided by a collector electrode into two parts of substantially equal volume which can be switched to operate in opposition to zero the instrument in a position where ambient radiation exists. The meter comprises an ionization chamber 1 with anodes 2, 3 and a common collector electrode 4, a source 12, 13 of saturation bias voltage for each part of the chamber, ganged switches 14, 15 which in their upper " measure " position connect both parts of the chamber in parallel and in their lower " calibrate" position connect both parts in opposition and a valve 6 with its grid directly connected to the collector electrode so that its anode current as measured by meter 8 is a logarithmic function of the ionization current in the chamber. The valve is stabilized in this condition by the ionization current produced by a low strength α particle emitting source 11 positioned in the upper part of the chamber. In the calibrate position, in the presence of ambient radiation, equal and opposite currents are produced in each part of the chamber and meter 8 is set to zero by variable resistance 7. In a second arrangement (not shown) a further ganged switch applies a fixed bias voltage to the valve grid during switch over and prevents the circuit disturbance produced by an open grid circuit and an ionizing source of known dose rate, positioned adjacent the upper chamber, can be unshuttered to provide a scale calibrating point.

June 6, 1933, No. 16297. Convention date, June 7, 1932. [Class 100 (iv).] In a vibrator mechanism for two-colour inkribbons for typewriters, the ribbon fork 2 is linked to an arm 8 which is loose on the universal shaft 4, and is actuated by the rotation of the shaft 4 to an extent depending on the position of a strip 11, which slides in apertures in two arms 9 which are fast to the shaft 4. The strip 11 carries two adjustable screws 12, 121 and, by sliding the strip longitudinally, either or neither of the screws may be made to engage a projection 10 on the arm 8. Thus, when the shaft 4 is rotated by the actuation of a key, different amounts of throw, or no throw at all, are produced in the ribbon fork.

Abstract: 151,728. Gilbert, C. E. G. June 28, 1919. Actions, pneumatic. The player action comprises an horizontal main air duct and a single row of separable blocks each comprising one or more complete operative units. Fig. 1 shows a set of three continuous blocks and Fig. 2 a side view of one unit. Secured to an horizontal bar of wood A<1> is the single row of separable blocks B, each comprising one or more complete operative units, including the striking-bellows, valves, and diaphragms, and having the necessary interconnecting air passages, and an air-channel C communicating with the main air-duct A running along the bar. Each block is preferably equal in width to two or three notes and contains two or three units vertically superimposed. The length of the row is equal to the length of the row of notes. One unit G is shown in section. It comprises a diaphragm M attached to a valve H which works between the faces L inserted in the bored opening R. The - other end of the valve works in a spring S. The bellows D (with front plate D' moving parallel to the block) actuates a link E for striking a note. The unit G is closed by a plate P and the space between the diaphragm and plate communicates with the tracker piping through the duct 0. Normally the valve H closes the opening L<2>, thereby shutting off the passage F to the bellows from the suction duct A. When an opening in the tune-sheet admits air into the duct 0, the diaphragm M moves and with it the valve H. The latter uncovers the opening L<2>, closes the opening L<1> and puts the bellows D into communication with the duct A. The spring S restores the valve H to its original position.
