Title: Improvements in or relating to printing or decorating processes
IPC: B41M1/12
Filed: 1952-03-22
Abstract: 737,461. Ornamenting. PRIESTLEY, C. H., and MURRAY, G. L. March, 16 1953 [March 22, 1952], No. 7437/52. Class 93. [Also in Group XVI] A process for printing on or ornamenting articles of cupped or other non-planar shape comprises the steps of preparing a stencil screen from the design or other matter to be printed on the article, printing through the stencil onto a substantially flat plate, bringing a resilient pad into contact with the flat plate to extract the design therefrom and then pressing the resilient pad against the article to transfer the design thereto. The frame supporting the stencil screen may be hingedly supported in relation to the flat plate so that the design is printed in the same position each time. The pad 18, Fig. 2, is brought down onto the flat plate 12 as shown, spreading radially as it is pressed into contact. The pad may be parabolic in shape for printing on cupped and similar shaped articles but other shapes of pads may be used where more suitable to the shape of the article to be printed upon which may be e.g. of plastics, glass, ceramics, papier-mÔchÚ or the like. The pad may be composed of organic or mineral jellies, e.g. gelatine or gelatine based material. The resilient part of the pad may be secured to a plate 21 connected to a rod 22 whereby vertical movement is effected, Fig. 3, shows the printing of a glass bowl 19 having a dome 20 at the bottom, the pad distorting so as to conform to the shape of the article and transferring the design thereto. The article is located by members 25 on a base 24. The base may be extended to support those parts of the article against which pressure is exerted. The different parts involved in,this process may be arranged on a single base and arranged for example so that the plate 12 is first displaced under the screen and printed, then under the vertically movable pad and the design transferred thereto. The plate 12 is then returned to the initial position and the base 24 carrying the article 19 is moved under the pad for printing as described.

Abstract: 945,164. Vacuum-moulding hollow articles. HYDRO-CHEMIE A.G. March 3, 1960 [March 4, 1959], No. 7548/60. Heading B5A. A foil F either cut from a roll A or fed from a container A<SP>1</SP> is located in a frame at B, raised to C where the frame is locked, heated at D and E, vacuum-moulded at V, returned to C, where the frame is unlocked, the moulded article removed at B, trimmed at G, and the trimmed material fed to H when it is ejected into a container J. The clamping frame which is adjustable in size, comprises upper and lower members 4a, 4b, and four frames are mounted on a driving shaft 1 to be rotated through 90 degrees to the various stations. Each corner of the frame has a locking member 7, Fig. 6, comprising a bolt 46 with a neck part 47 with which looking keys 49 engage. In operation with a foil between the frame parts 4a, 4b, the parts are forced together by bolts 33, and a cam operates a linkage to lower a rod 54, and as the top 53 of the rod 54 is withdrawn, springs 50 push the keys 49 into engagement with the part 47, to lock the parts 4a, 4b in the clamped position. The bolts 33 are then lowered, and the shaft 1 rotated to carry the clamped sheet to the heating station D. When a frame carrying a moulded article arrives at station C, the process is reversed, i.e. the bolts 33 and the rod 54 are lifted to support the frame, and cam the keys 49 outwardly, respectively. The bottom 4b of the frame is then lowered with the locking member 7, and rams 66 are lowered to push the moulded article together with an article-receiving box 61 downwardly.

Title: Shaker conveyors
Inventor: SOMOGYI FRANCIS PAUL
IPC: B65G27/00
Filed: 1949-03-21
Abstract: 659,274. Jigging conveyers. SOMOGYI, F. P. March 21, 1949, No. 7667. [Class 78 (i)] A shaker conveyer trough is supported by means of rollers or like rolling elements on a frame which is freely mounted for longitudinal oscillation upon a fixed support, the trough supporting means providing a position of rest for the trough with respect to the frame and providing also a restoring force which urges the trough at any moment towards the position of rest and which increases rapidly as the trough moves in the conveying direction, and relatively slowly as the trough moves rearwards Fig. 1. The conveying trough 18 is mounted on grooved wheels 22 which run on shoes 11 adjustably secured to a frame 1. Frame 1 is provided with grooved wheels 8 running on short rails 9 on fixed supports 10, and is reciprocated with a simple harmonic motion, e.g. by a long connecting rod 6 and a crank-shaft 4 rotating in fixed bearings. The resultant motion of trough 18 is dependent on the shape of the shoes 11 and on springs 24 which extend between trough 18 and frame 1. The arrangement is such that trough 18 is in its rest position with respect to frame 1 when nearly at the bottom of the straight rear portion of shoes 11 and springs 24 are forwardly inclined as shown. The front portion of shoes 11 is abruptly curved so that, when oscillating, as trough 18 moves from rear to forward limits of its motion with respect to frame 1, springs 24 first contract and then expand to a greater length than initially. Material is thereby conveyed forwardly along the trough. Fig 5. Shoes 11 are provided at their rear ends with a pair of spaced plates 13, secured thereto by welding. A bolt 14 is passed through the ends of the plates, forming a slot through which a threaded link 15 is passed the lower end of the link being pivoted to frame 1. To the front end of shoes 11 a bracket 12 is fixed, which bracket is pivoted to frame 1. Adjusting nuts 16, 17 permit shoes 11 to be tilted as required.

Abstract: 622,556. Fluid - actuated valves. BRITISH OXYGEN CO., Ltd., and GODFREY, R. C. March 26, 1947, No. 8196. [Class 135] [Also in Group XXVI] A pressure-reducing valve of the type comprising a main valve 6 controlling the flow of fluid from an inlet 11 to an outlet 13 and balanced with respect to both inlet and outlet pressures, a pressure-responsive valve-actuating member, such as a piston 8, connected to the low pressure side of the valve and exposed on one side through a passage 58 to the outlet pressure which tends to move it in a direction to close the main valve and exposed on its other side to the pressure in a regulating chamber 9, a pilot valve 10 controlling a passage 27, 31 leading from the inlet 11 to the chamber 9, and a second pressure-responsive valve-actuating member, such as the diaphragm 35, connected to the low pressure side of the pilot valve and exposed on one side to the same pressure as that in the regulating chamber which tends to move it in a direction to close the pilot valve and acted upon on its other side by a static loading, such as the adjustable spring 44, is characterized in that the pilot valve is balanced with respect to the fluid pressures of the inlet and of the regulating chamber. For balancing purposes, valve 6 carries a piston 14 of which the diameter is equal to that of the seat of the valve ; the inlet fluid pressure acts in opposite directions against the inlet side of the valve closure member and the inside face of piston 14, and the outlet pressure acts in opposite directions against the outlet face of the valve closure member and, through a passage 20 and a chamber containing the valve loading spring 18, against the outer face of piston 14. Pilot 'valve 10 is balanced in a similar manner by a piston 32. The spindle 21 connecting valve 6 to piston 8 is coned to prevent the jet of pressure fluid flowing through the valve from impinging and exerting a pressure on the piston, and a yielding washer 57 is provided for the same purpose. A small leak is pro. vided between the two sides of piston 8. To prevent hunting, the piston is fitted with rubber rings 50 acting as friction brakes, but to prevent undue damping due to air entrapped between the rings during the initial insertion of the piston, ports 51 are provided to allow this air to leak away. Pistons 8, 14 and 32 could be substituted by diaphragms or bellows.

Abstract: 416,464. Valve circuits for wireless reception. ARMSTRONG, J. J. V., 12, Church Street, Liverpool.-(Telefunken Ges. f³r Drahtlose Telegraphie ; 12, Hallesches Ufer, Berlin.) March 16, 1934, No. 8260. [Class 40 (v).] In a short -wave receiver of the "retarding field " type in which a high positive voltage is applied to the valve grid a direct current voltage proportional to the signal is produced in the circuit of the retarding electrode and used to control the gain. Fig. 6 shows an arrangement in which the detector V2 has its output taken from Rg and produces a gain control voltage across resistance R which is applied to the high frequency amplifier V1. The detector in this arrangement operates at the lower bend of its characteristic. In a modification (Fig. 7 not shown), the control is applied to a grid adjacent the cathode in the detector valve which may be screened as shown in Fig. 8, the electrode S at cathode potential serving as an electron emergence surface, the electrode SG being maintained at a fixed high potential and the control voltage being applied to the grid G. With this arrangement the influence of the grid anode GA on the supply of electrons from the cathode is suppressed.

Abstract: 1,191,085. Counting apparatus; selective signalling. GENERAL ELECTRIC CO. 14 Feb., 1969 [29 Feb., 1968 (3)], No. 8263/69. Headings G4A and G4H. In a measuring system in which pulses are produced each representing a known increment of the variable being measured, for example pulses from an interferometer where each pulse represents a displacement of 3À1142697 x l0<SP>-6</SP> inches, the pulses are counted and means are provided for periodically subtracting unity from the highest non-zero denomination of the counter and for accumulating a corresponding multiple of the incremental value of each pulse. In this way the total accumulated does not lag far behind the total number of pulses produced, and it represents the value of the variable being measured in more convenient units. Means may be provided to modify the incremental value of each pulse in accordance with the existing ambient conditions. The system may form part of a rectroactive machine tool control loop (Fig. 6, not shown). As described add and subtract pulses UPL, DNL, Fig. 2, from an interferometer are passed, via a sign stage 18 and leads UPI, DNI, to a reversible, binary-coded-decimal gated counter, Figs. 3, 4, the sign stage 18, Fig. 2, functioning either to connect lead UPL to UPI and DNL to KNI if a sign trigger 72 is on indicating a positive sign, or to connect lead UP1 to DN1 and lead DNL to UP1 if the sign trigger is off. The state of the sign trigger is determined by the first pulse from the interferometer that occurs after the counter reaches zero, which is detected by a gate 65. This pulse also always passes via a gate 73 to the add lead UP1. The contents of the counter are examined by a recognition circuit 15, Fig. 2, which, when an arithmetic control unit (not described) is ready, and when a buffer store is ready, this being evidenced by the presence of signals RECO, PCR, produces a signal #CORR 1 or #CORR 10 or #CORR 100 indicating the highest non-zero denomination of the counter. This signal then causes a one to be entered into a corresponding stage of a buffer store (Fig. 5, not shown) and a one to be subtracted from the corresponding denomination of the counter. Under control of the buffer store, a corresponding multiple (1, 10 or 100) of the incremental value of each pulse from the interferometer is then transferred (by means not described) to an accumulator. This process continues until the counter is empty.

Abstract: 937,086. Automatic exchange systems. PHILIPS ELECTRICAL INDUSTRIES Ltd. March 5, 1962 [March 8, 1961], No. 8433/62. Class 40 (4). In a system in which subscribers' lines are connected to a link circuit by the operation of a pair of relays, these relays are arranged to release in succession in order, when required, to connect up a source of busy tone. In the case of link circuit 4, a calling line is connected to feed relay X by relays 1A, 1B or 2A, 2B, while a called line is connected to feed relay Y by relays 1C, 1D or 2C, 2D, these operations being controlled by the marking of wires 6, 7 in a manner not shown. The connecting relays are of the kind that remain in their operated positions until restored by current through their releasing windings shown at the foot of the Figure. Assuming an established connection, when one subscriber hangs up relays E, F (which are dependent on X, Y) fall back in turn and thus one connecting relay of each operative pair releases before the other. Relay G now energizes over the remaining subscriber's loop and connects busy tone thereto from a source 12. In the setting up of a connection, relays E, F energize initially over wire 13, and if the called line is found busy this wire is opened, with the result that busy tone is applied in a similar way to the calling line. Relay G has opposing windings to avoid its operation in series with line relay L.
