Abstract: 102,869. Twells, A. H. April 25, 1916. Thermostats. - Relates to the control of the temperature of heaters, such as liquid heaters, steam heaters, radiators, &c. by causing the expansion and contraction of the heated body to actuate a valve supplying the heating- fluid by the bending and straightening of a bar. The bar is supported on one side, and is bent 'by members bearing on the other side, such members being actuated by the expansion and contraction of the heated body. In one arrangement, Fig. 1, the bar 3, when straight, allows the valve 2 supplying heating-fluid to the body 1 to be held open by a spring 17. The bar bears at its upper side against the upper edges 10 of holes 9 in rods 7 adjustably secured to the base 11 of the body 1, and at its underside rests on members 4 secured to the cover 6 of the body 1. Expansion of the body 1 causes the bar 3 to bend downwardly at the centre to close the valve. In a modification, the bar 3 is normally bent as shown in broken lines, and is straightened bv the expansion. Adjustment between the bar 3 and the valve spindle 15 is provided by nuts 16 on the spindle. In a modification, Fig. 5, a sleeve 18 passing through a hole in the bar 3 is disposed between nuts 19, 20 engaging the screwed spindle 15.

Filed: 1948-02-27
Abstract: 651,428. Compound sheet materials. BROWN, BIBBY, & GREGORY, Ltd. Feb. 27, 1948, No. 6022. Convention date, May 19, 1945. [Class 140] A flexible tearresistant protective covering, for a sheet or film of natural and/ or synthetic rubber or vulcanizable composition containing the same having a normally tacky uncured surface, comprises plies 10, 12 of regenerated cellulose united with adhesive 14 and subsequently embossed to provide upstanding portions, as at 16, extending over the entire surface which is to be applied to the tacky surface. The embossing reduces the area of rubber with which the covering is in contact and so reduces the frictional adhesion therebetween, thus facilitating clean stripping of the covering prior to the use of the sheet for repairing rubber articles, e.g. patching inner tubes of tyres. The adhesive comprises natural or synthetic resin or cellulose derivative, e.g. polyvinyl acetate, polyvinyl butyrate, alkyd resins, cellulose nitrate, cellulose acetate. as a filmforming ingredient, and a plasticizer therefor, and may.be applied as a solution comprising, for example, polyvinyl acetate, tricresyl phosphate and ethyl acetate to which a pigment or dyestuff may be added. The laminµ are consolidated under pressure, or heat and pressure. The embossed design, formed of and divided by straight or curved lines, may comprise diamonds, as shown, herringbone, squares, rectangles, parallelograms, rhombi, corrugations, and it is stated that, for optimum results, the raised elements of the design are spaced from each other by depressions as at 18 which intercommunicate to form straight depressions terminating at the edge of the covering so that when the covering is applied to the tacky surface air is not entrapped in individual depressions but is forced to the edges. The covering may form an interliner between consecutive windings of a continuous film of uncured rubber, Fig. 3 (not shown), or be applied to a rubber film having a fabric backing or one cured surface, Fig. 4 (not shown).

Title: Improvements in and relating to hydrostatic drives for imparting alternating movements to members
Inventor: KLAUS ROLF
IPC: F16H43/00
Filed: 1968-02-07
Abstract: 1,220,233. 233. Hydraulic circuit producing reciprocating motion. WERKZEUGMASCHINENKOMBINAT "FRITZ HECKERT" KARL-MARXSTADT VEB. Feb.7, 1968, No.6076/68. Heading F1P. In an hydraulic system having a reversibleoutput pump 2 controlled by a servovalve 6 and arranged to supply liquid alternately in one direction or the other to a hydraulic motor 1 and thereby cause it to perform alternating movements, the servovalve 6 is controlled by an electronic circuit including a function generator 14 receiving input signals from switches 16 operated by the motor 1 at the limits of its movement. The servovalve 6 is magnetically operated in accordance with the signals received from a servo amplifier 11 in the electronic circuit. The position of the servovalve determines the flow from a constant delivery pump 10 to devices 3 for adjusting the output and direction of the pump 2. The speed of the motor 1 is predetermined by adjusting a pair of ganged potentiometers forming part of the function generator. This adjustment establishes the voltage input signal to the function generator and the polarity thereof is changed each time a limit switch is operated. When the polarity of the signal is changed the function generator stores the signal in an integrator and thereafter limits and amplifies the signal before feeding it to a comparator 12. The comparator 12 compares this signal with feedback signals transmitted from means 4 responsive to the position of the pump output adjusting devices 3 and from a capsule 13 responsive to the pressure differential across the motor 1. The output from the comparator 12 is proportional to the necessary change in the setting of servovalve 6.

Abstract: 231,310. Barty, T., Burrows, F. A., and Westinghouse Brake & Saxby Signal Co., Ltd. March 13, 1924. Fluid-pressure. - A pedal-operated driver's brake valve for use on motor - vehicles fitted with fluid - pressure braking apparatus comprises a casing 1, closed at its upper end by a diaphragm 9 and connected to the brake cylinder at 28, and inlet and outlet valves 4, 16, the former of which is normally closed by a spring 5, whilst the latter is normally held open by a link 22 rigidly mounted on the brake rock shaft 23. With the pedal 24 in the raised position shown, the brake cylinder accordingly exhausts through the pipe 28, an axial passage 17 in a piston member 15 secured to the diaphragm, and ports 18. The initial depression of the pedal, from a - - b permits the valve 16 to be closed by a spring 20, and in its further movement it bears on a collar 27, thereby depressing the members 15, 9 by means of a spring 26. When the pedal reaches the position c, a downward extension of the member 15 engages the upper end of the valve 4, and its further movement opens this valve to supply pressure fluid to the brake cylinder until the pressure established in the casing 1 is sufficient to raise the diaphragm against the pressure of the spring 26, when the valve re-closes. If at any time the brake cylinder pressure exceeds that for which the spring 20 is set, the valve 16 opens, so that by adjusting the setting of this spring by a threaded plug 21, the maximum brake pressure may be regulated.
