Title: Printing mechanism for accounting and like machines
IPC: B41J9/30
Filed: 1951-10-03
Abstract: 701,239. Printing mechanism for accounting &c. machines. NATIONAL CASH REGISTER CO. Oct. 3, 1951 [Oct. 5, 1950], No. 23001/S1. Class 100 (4) Hammer impression arrangements. - The printing mechanism for an accounting or like machine comprises a printing hammer 10 resiliently coupled by a rubber bushing 12 to a driving shaft 14, and a latch 26 for restraining the hammer 10 when the shaft 14 is partially rotated to stress the bushing 12 so that when the latch is 'subsequently released the hammer effects a rapid printing stroke and rebounding is avoided. The bushing 12 may be secured to the hammer 10 and shaft 14 by a chemical bond or by forming the hammer with a split hub 23 to provide for radial adjustment of the hammer. A screw 24 clamps the hub in position. The shaft 14 may carry a plurality of hammers 10 which are all simultaneously operated by an arm 15 and mechanism 16-20 from a pair of driven cam plates 21 shaped to give one or two operations of the hammers per machine cycle as required. Before the cams are operative a machine shaft 46 and an arm 50 secured thereon are rocked counter-clockwise, and by means of a pin 48 and a spring 51, a pawl 45 is edged counter-clockwise away from a pin 47 on the latches 26. If the nose 56 of the pawl 45 engages the surface of a selecting disc 53 the pawl 45 is not disengaged from the pin 47 but if the nose registers with a notch 55 then the latch 26 is free to move. This latch movement if effected immediately by further machine driven cams which reciprocate a pitman 36, and mechanism 38, 27, 28, 31, 29, 30, and place a shoulder 39 of the latch 26 in the path of a stud 25 on the hammer 10. The rocking of the hammer shaft 14 is now effective and the bushing 12 of the selected hammers is torsionally stressed, while unselected hammers travel unrestrictedly to the dotted position shown but effect no impression. The latched hammers are, later in the cycle, released and they make a rapid impression stroke through the potential energy stored in the stressed rubber bushing. In a modification, Fig. 5 (not shown), the latch and the pawl are integrally formed, a nose portion arresting the hammer 10 by engagement with a shoulder formed on an arcuate plate adjustably secured to the hub of the hammer.

Sport, appliances for.-In the manufacture of skate-blades with a thickened edge by stamping the blade out of sheet steel and upsetting the edge in the cold in order to form ribs on each side of the running-edge, the edge is upset progressively step by step from one end to the other and the outward flow of metal is limited at both sides to correspond to the cross-section of the thickened edge lateral support being provided for the blade edge to the rear and in front of the portion being upset. Apparatus similar to a file-cutting machine may be employed, comprising a slide c, Fig. 10, with clamping jaws b to hold the work a, movable step by step under a press-slide or spring hammer f carrying the upsetting-stamp g. The channel h, Fig. 3, in the face of the stamp comprises a deep narrow portion 1 corresponding to the blade edge before upsetting, a portion 2 of gradually decreasing depth and increasing width which performs the upsetting operation, and another portion 3 of the width and depth of the thickened edge h<3>, Fig. 6. The bed d is preferably so inclined that the centre line of the stamp g bisects the angle x between the upper edge of the already upset portion and the sloping portion being shaped by the part 2 of the stamp. In the modification shown in Figs. 11 and 17, the channel in the stamp g terminates at the upsetting portion, and the lateral support for the part of the edge already thickened is afforded by channels k in the clamping jaws b, this construction enabling a thickened edge with downwardly converging lateral faces to be formed. Fig. 19 shows means for clamping and unclamping the jaws b against a fixed wall of the slide c by a longitudinal wedge n whereby tedious finishing operations on the jaws by grinding after hardening may be avoided. At each end of the wedge n is provided a hammer-spindle o influenced by a powerful spring p and carrying a tappet q engaged by a cam r on a shaft s with fast and loose pulleys t. The clamping pressure of the wedge n on the jaws b when the left-hand spring-hammer o is actuated serves to straighten the jaws if they happen to be bent, and the right-hand spring-hammer provides for easy release of the jaws.

Title: Improvements in variable ratio hydraulic transmissions
IPC: F16H61/46
Filed: 1963-06-13
Abstract: 1,003,008. Hydraulic transmission of power; change-speed control. SOC. INDUSTRIELLE GENERALE DE MECANIQUE APPLIQUEE S.I.G.M.A. June 13, 1963 [June 26, 1962], No. 23555/63. Heading F2D. A continuously-variable-ratio transmission for a motor car comprises an engine 2 driving a variable capacity pump 1, which may be of the axial piston, tiltable swashplate type, Fig. 3 (not shown), connected in closed circuit by pipes 7, 8 with a motor 4, which may also be of variable capacity, the motor driving a road wheel 5, two pressure-responsive servos 19, 20 connected by pipes 25, 26 to the pipes 7, 8 acting against spring bias with increasing pressure upon a force amplifying device 27 and a lever 14 to reduce the capacity of the pump 1, thereby effecting a ratio downshift. If the engine 2 is driving the car, then the pump 1 supplies the motor 4 through the pipe 7 in which an increase in pressure is occasioned by an increase in load applied to the road wheel 5; accordingly, the increase in pressure is applied through the pipe 25 to the pressure responsive servo 19 which consequently establishes a lower ratio. If, however, the road wheel 5 is driving the engine 2, as suring overrun, then pressure increases in the pipe 8 and is applied through the pipe 26 to the other servo 20 which in turn establishes a lower ratio, for engine braking. In the form shown, the motor 4 is also of variable capacity and is similarly controlled by two additional pressureresponsive servos 19a, 20a, but in a modification, Fig. 1 (not shown), the motor is of fixed capacity.

Patent GB-643788-A (GB)
Title: Production of acid chlorides of aromatic polybasic acids
IPC: C07C51/58
Filed: 1947-08-27
Abstract: Acid chlorides of polybasic aromatic acids are obtained from compounds of the formula R-(CCl3)x, where x is 2 to 5 and R is an aromatic hydrocarbon radical having a valence equal to x, the valence bonds being attached to non-adjacent carbon atoms, by heating them with a dicarboxylic acid capable of forming an anhydride, preferably in the presence of an acidic catalyst, and separating the acid chloride by distillation.  The starting materials are obtained by chlorinating in the presence of light suitable methyl-substituted hydrocarbons, e.g. m- and p-xylenes, mesitylene, di- and tetramethylnaphthalenes, di-, tetra- and pentamethyl-diphenyls.  For the hydrolysis, maleic acid is preferred, but succinic, glutaric, phthalic, diphenic and the o-naphthalene dicarboxylic acids may also be used.  The catalyst may be ferric, zinc, stannic, or aluminium chloride, antimony trichloride, sulphuric acid or p-toluene-sulphonic acid.  Examples show the production of terephthaloyl and isophthaloyl chlorides from para- and meta-xylene respectively and also from a commercial mixture of the two, the isomeric bis-trichloromethylbenzenes being separated by crystallizing out the para-isomer and distilling the filtrate.  The Specification as open to inspection under Sect. 91 refers to the production of the acid chlorides by hydrolysis with water prepared in situ by any chemical reaction which does not affect the acid chlorides, and is not restricted to any particular method of generating the water.  This subject-matter does not appear in the Specification as accepted.

Filed: 1951-10-11
Abstract: A body suitable for filtering liquids comprises a coherent body of exfoliated laminar material, e.g. vermiculite which has been permeated with a liquid which on contact with a binder congeals it instantaneously.  In filtering liquids containing colloidal particles pressure parallel to the laminations is applied whereby fine ducts result.  The filtering characteristics can be controlled both by the magnitude of pressure applied and its direction.  Portions of the body may be sealed by impregnation with a fluxing material followed by sintering.ALSO:A mass of exfoliated laminar chemically inert material is permeated with a liquid which on contact with a binder congeals it instantaneously, the mass then being formed into a coherent body. Pressure may subsequently be applied to the body which may then be baked.  Vermiculite is the preferred material and specified binders are ethyl silicate with ammonia as congealant and sodium silicate with aluminium sulphate, potash alum and/or sodium borate as congealant.  Surplus congealant may be flushed out.

Filed: 1938-08-11
Abstract: 517,953. Railway signals and stopping trains. GIOVANNELLI, I. Aug. 11, 1938, No. 23767. [Class 105] A train makes two contacts 3, 4 with line wires 1, 2 and through a change-over switch 19, for forward and reverse running,' and a switch 45 energizes the line wires from either a generator 6 or a battery 10. A train running in the reverse direction energizes the lines reversely and produces an operating condition. This condition is also produced by the closing of a switch 23 by an official, or of a switch indicating a broken bridge or a land slide. In this condition, a horn 18 and a motor 27 are actuated. The motor 27 moves the regulator lever 33 through-gear 29, 30, 42, shutting off steam, closing contacts 35, 36 and ultimately opening contacts 40. Closing contacts 35, 36 energizes a solenoid 11 which operates a visual signal 15 and brake devices 63, closes a stick circuit .at 26 and breaks at 24, the circuits of the motor 27 and the horn 18. The lever 33 can be reset by releasing the pawl 42. The failure of a bridge connects live wires 1, 2 by means of a switch. The fixed lower part of which is carried by an arch of the bridge and the movable upper part by a cable supported independently of the arch. The line wires are bridged also, in the case of a land slide, when rocks, etc. fall on a disc and the added weight causes the contacts to be brought together.

Title: Improvements in and relating to electric motor and like controllers
IPC: B60L15/22
Filed: 1956-08-01
Abstract: 810,058. Controllers. BROWN BOVERI & CIE A.G. Aug. 1, 1956 [Aug. 1, 1955], No. 23788/56. Class 38 (3). Relates to an arrangement in electric locomotives for regulating the electro-pneumatic drive of a multi-contact, switch in accordance with the adjustment of a master controller. The hand wheel of the master controller may be moved from neutral to a desired position in which it is held by a notching device 4, a contact drum 8 being moved through a spring coupling 5, 6, 7. Initially, the contact drum advances by only one step and is then stopped by a member 9 engaging a claw 10 which is held fast by a locking wheel 12a. In this position, a line 51 is energized and control valve 25 of air motor 20 is actuated so that the shaft 36 of the multi-contact switch is driven through one step, whereupon conductor 55 is energized through auxiliary switch 17 and locking magnet 15 is actuated. Under the action of cam 14a, lever 13a releases wheel 12a and the control drum is advanced one further step, by means of the tensioned spring 6, until it is stopped by lever 13b engaging wheel 12b. In the new position, line 52 is energized so that the air motor is advanced to its second step. The magnet 15 is de-energized and releases the control drum 8 for a further step. This cycle is repeated until the position pre-selected by means of the hand wheel is reached and the spring 6 exerts no further torque. The claw 10 returns to a position of equilibrium, and the wheels 12a, 12b are suitably positioned when further movement of the multi-contact switch is desired. The wheel 1.2 a may carry a scale for indicating the switching-step which has been reached. A relay may be provided which responds, when the current passing through its coil reaches a given value, to connect the control valves of the air motor to a contact drum driven by the shaft 36. This causes the air motor to be halted until the current falls to an acceptable value, Fig. 2 (not shown). A number of multiple-contact switches may be regulated from a single master controller, in which case the retraction spring 6 for the locking magnet 15 is replaced by another magnet having intermittent energization.
