Title: Improvements relating to printing mechanism for weighing machines
IPC: G01G23/18
Filed: 1920-07-09
Abstract: 148,310. Meyer, G. W. June 4, 1914, [Convention date]. Printed records, apparatus for giving.-Relates to a printing-apparatus for use in conjunction with a postal weighing-machine, and comprises a type drum which rotates and moves axially when liberated by the operator, and presses a catch, previously set by the usual indicating-spindle, in to a stationary ring of teeth, the type drum being afterwards arrested by a stop thereon coming into engagement with the catch. The indicating spindle 3 of the usual dial 2 extends in to a casing 8 and carries a flexible catch 6. Co-axial with the shaft 3 is a shaft 10 bearing a cord drum 14, type drum 11 and two disks 22, 23 connected by springs 24. When the indicating spindle 3 has come to rest after application of a load, the operator depresses a key, thereby drawing-down a detent 19 and allowing the type drum to rotate under the influence of a weight 16. The type drum is at the same time moved axially by a pin-andgroove arrangement 25, and pushes the disks 23, 22 axially so as to press the catch 6 in to a stationary ring of teeth 5, thus locking the catch in a definite position corresponding to the weight. The movement of the type drum continues until an arm 27 thereon meets the catch 6, after which the operator selects and presses a key corresponding to one of a series of cost rings 29 - - 33. This operation actuates a printing-hammer for the selected ring and also for a weights ring 28, and thereby makes a printed record of the cost and of the weight on a ticket previously inserted in a slot. Additional printing-type 42, 43, 44, struck by the same hammer as the weights ring 28, are used to print a record of time, place, name of official, serial number, and prepayment made or omitted. The type drum is returned and the weight 16 is rewound by means of a handle 17, the two disks 23, 22 being driven back by a projection on the type drum engaging an annular recess in the hub of the disk 22.

Title: Pneumatic pressure regulator
IPC: G05D16/16
Filed: 1956-07-02
Abstract: 827,538. Fluid-pressure servomotor-control systems. DREYER, ROSENKRANZ & DROOP A.G. July 2, 1956 [July 2, 1955], No. 20363/56. Class 135. A process pressure in a chamber 13 between diaphragms 12, 14 is balanced against a set presure in a chamber 15 between diaphragms 14, 16. Variations in the process pressure regulate escape of air through a nozzle 1 from a chamber 2 supplied from a constant pressure source 18 through a restriction 10 to a chamber 11. The resultant change in pressure in chamber 2 moves diaphragms 3, 3 to admit air from 18 past a valve 7 into a chamber 4 or release air from said chamber to atmosphere through a port 9. The change in pressure in chamber 4 reacts in chamber 11 to restore diaphragms 12, 14, 16 and to re-adjust the escape from nozzle 1 to restore diaphragms 3, 3 and valve 7 to their original positions, thus providing a proportional response to the process pressure variation. The pressure from chamber 4 also builds up in a chamber 17 through an adjustable needle valve 21 to provide an integral response pressure on the diaphragms 12, 14, 16. This pressure in chamber 17 acts on another diaphragm 20 which controls a nozzle la to regulate the pressure in a chamber 2a supplied from source 18 through a restriction 10a. This pressure acts through a diaphragm 3a to regulate the supply of pressure to, and exhaust from, a chamber 4a through a valve 7a. The pressure in chamber 4a is in direct proportion to the integral component of the process pressure variation and is transmitted to a line 19 leading to the actuating device of a pressure regulator controlling the process pressure.

Title: Improvements in or relating to processes for coating surfaces with cellulose derivative lacquers
IPC: C09D101/08
Filed: 1938-07-12
Abstract: 516,973. Coating surfaces; cellulose derivative organosols. COMMERCIAL SOLVENTS CORPORATION. July 12, 1938, No. 20624. Convention date, Aug. 16, 1937. [Class 95] [Also in Group IV] A process for coating surfaces with a cellulose derivative lacquer comprises applying to said surface, at a temperature, of the liquid lacquer, substantially above room temperature, a cellulose derivative lacquer including a relatively high proportion of slow evaporating components and having a concentration of solid components substantially greater than the optimum concentration for application at room temperature. Such lacquers, containing 20 per cent. more solids than the optimum concentration .at room temperature, may readily be applied at 15-20‹C. above room temperature, and, if applied at 50‹C., lacquers may be formulated with a concentration of solids from 35-50 per cent. greater, than the optimum concentration for application at 25‹C. The relatively high proportion of slow evaporating solvents and diluents compensates for the more rapid evaporation of the solvent mixture at the higher temperature, and ensures adequate flow of the material after application. Any of the usual cellulose derivatives, such as nitrocellulose, cellulose acetate and ethyl cellulose, may be employed, together with compatible plasticizers, resins, pigments, dyes, and other ingredients commonly present in lacquers. Specified additional ingredients are dibutyl phthalate, dibutyl tartrate, tricresyl phosphate, castor oil, alkyd resins, dammar, ester gum, carbon black, lead chromate, titanium dioxide and zinc oxide, and specified solvents and thinners include ethyl alcohol, ethyl acetate, butyl alcohol, butyl acetate, butyl propionate, methyl lactate, toluol, xylol and petroleum naphtha. Examples are given. The lacquers may be applied, e.g., by spraying, brushing or dipping, or by means of rolls, and should be preheated to the desired temperature. In the case of spray application, the lacquer supply may flow to the spray guns through heating coils, and the air for the spray may be preheated.

IPC: H01H1/28
Filed: 1918-12-16
Abstract: 121,608. Richter, M. B. Dec. 17, 1917, [Convention date]. Retractive switches; s w i t c h e s , quick-break. - Change-over switches especially for telephone and telegraph purposes comprise a number of superimposed fixed and movable spring contacts y and n, respectively, with their fixed ends all facing the same way to facilitate the permanent connexions, operated by one or other of two slides i' (one on each side of the bundle of contacts) carrying insulating-teeth k<1> which engage the movable contacts. The slides, which are held and controlled at their lower ends by springs p, have each a pin and socket connexion with one of the two levers h<1>, whereby the slides are held at their upper ends. By moving the actuating- lever f over to the right, the roller v<1> depresses the lever h<1> against the action of the spring w, causing it to roll upon and depress its slide and bring some of the movable contactstrips into engagement with fixed strips according to the function of the switch. When the actuating-lever f is released, the original position is restored under the action of the springs w, p; or, by providing notches z in the levers h<1> in which, in the ' on ' position, the rollers engage, the switch may be retained set in the ' on ' position. By moving the actuating-lever f from the mid-position to the left, the roller v<2> depresses the second lever h<1> and its slide and completes other contacts of the switch. The two levers h<1> are loosely joined at their free ends by a pin x on which a sleeve is mounted carrying one end of the spring w, the other end of which is fixed. When the actuating-lever is moved, the pin x takes up an inclined position and the spring moves to the upper end of the pin where its controlling action on the unmoved lever h<1> is increased so that there is less liability, when the actuating- member returns to the off ' position, of its actuating the unmoved lever if it should accidentally pass the middle position.

A multi-way-fluid control valve is made up of a number of metal or plastic sections C with rabbeted end faces housing interchangeable valve seats S or a gasket G, a through-bore 22 for valve members V and a port 24. When the valve is not manually actuated cylinder section C<SP>1</SP> may be employed at one or each extremity of the valve sections C, each section C<SP>1</SP> housing a piston P of larger diameter than the valve V. The assembly is closed at each end by caps C<SP>11</SP> with an axial port 29 for the pilot fluid, the whole being held together by bolts B. The ports may be plugged as required. The valve members V are thin discs preferably spaced from the bore 22 and threaded to the adjacent valve member V, piston P or other actuator by a rod R. The seats S comprise an elastomeric annulus of rectangular cross-section with lips forming the seating surface for the members V; each seat may consist of two elastomeric discs separated by a metal or plastics guide 40 embodying arcuate slots 43 in the inner periphery; the discs and guide may be bonded. The guide may be inserted in a groove in a one-piece elastomeric seat element and the inner face of the guide may incorporate an O-ring to seal with the rod R. The valve may be loaded by a fixed or an adjustable spring and the cylinder section may be provided with a vent. The pilot pressure may act on a diaphragm instead of a piston, and the valve may be of the shuttle type actuated by the upstream and downstream fluid impinging on the valve member V. The valve may be mounted on a manifold containing passages connecting with the valve ports ; a gasket is interposed between the valve and manifold. The valve may be controlled by a pilot valve in the line to one actuating piston only, the other piston being supplied with controlled fluid which is only effective to return the main valve when the pilot path has been vented. Many different types of valves may be built up from the sections, which valves may be of miniature size and employed in logic circuits.
