Title: Improvements in a spray dispensing system
IPC: F16N7/34
Filed: 1950-06-09
Abstract: 673,521. Spray-producers. FARVAL CORPORATION. June 9, 1950 [April 21, 1950], No. 14477/50. Class 69 (iii) [Also in Group XXXIV] A spray dispensing system comprises liquid and air lines to which are connected, in spaced relationship, a number of spray devices each with means operative intermittently to deliver predetermined measured quantities of liquid to each spray device when the liquid line is placed under pressure, and with valve means controlling the admission of pressure air from the air line to each spray device actuated by the delivery of the liquid thereto. In one embodiment of a spray device, Fig. 1, a lubricant charge is fed alternately to the inlets 13 and 14 of a cylinder 3 in a body 1 and, considering the feed to the inlet 14, the lubricant forces a piston 16 upwardly and passes through a passage 12 to a cylinder 4. Lubricant pressure forces a piston 20 upwardly which forces a measured quantity of lubricant from the space above the piston 20 through passages 11 and 9 to a chamber 10. A piston 27 is then forced downwardly allowing lubricant to pass through passages 36, 37, and since the passage 37 is normally filled with lubricant, a measured quantity is delivered through a nozzle 38. Downward movement of the piston 27 opens a normally-closed spring-pressed air valve 30 and allows an air charge to pass from its inlet 34, through passages 35, 41 to a chamber 40 to form a spray with the lubricant from an outlet 39. The quantity of lubricant sprayed may be adjusted by altering the stroke of the piston 20, i.e. by altering the position of a nut 25. A number of such devices 1, Fig. 3, are connected to lubricant lines 48, 49, and to an air line 51, and a pump 45 delivers lubricant continuously to a shifter valve 46 which delivers it to a serving cylinder 47 which delivers a measured quantity of lubricant alternately to lines 48 and 49. Specifications 475,745, [Group XXVIII], and 513,388, [Group XXXIV], are referred to.

Title: Counter assemblies
Inventor: WOESS MICHAEL FRANCIS
IPC: G06M3/06
Filed: 1966-04-01
Abstract: 1,098,366. Counting apparatus. WOESS MANUFACTURING AGENCIES Ltd. April 1 1966, No. 14587/66. Heading G4D. In a counter for recording on a card initial and final values of digit wheels 12 of counters 2, 4, 6 e.g. a counter for attachment to a postal franking machine to record the amount of credit used, the record card is mounted in a tray 40 which is a sliding fit in a holder 46, the latter moving in slotted end plates 34, 28, transversely of its length to two positions corresponding to the initial or final reading. Printing or embossing of a reading is performed by a screwmounted trolley 52, moving along the card holder and having a roller which extends through a rectangular aperture in the holder to press the card against recording wheels 14 fixed to the digit wheels 12, the latter being mounted on a common shaft 8. Initially the trolley is moved to the right to record the initial reading of the counter and actuates a lever 90 which moves the shaft 8 to the right to lock the digit wheels of an auxiliary counter 6 against a detent 38. Also the trolley engages cam surfaces of the card holder to move it transversely of its length to the final reading position, this movement also causing a spring loaded bell crank (160) (Fig. 4, not shown), temporarily attached to the card holder by a pin 152, to rotate to a position in which it engages a pin 68 of the trolley screw to prevnet reverse rotation thereof. The trolley is thus locked in the right hand position until the crank (160) is released by withdrawing the pin 152 on releasing a ratchet (138, 140) (Fig. 3, not shown) operating on a shaft 120 via pinions (130, 128) (Fig. 4, not shown). The shaft 120 carries a further pinion 122 which meshes with a transfer pinion of the digit wheels of the main counter 2. The digit wheels of the counter 2 are then incremented by the franking machine until the transfer pinion meshing with the pinion (122) is incremented, whereupon the ratchet is released which in turn withdraws pin 152 to release the trolley. The trolley is then moved to the left to record the final reading of the counters, and again actuates lever 90 which moves shaft 8 to the left to release the digit wheels of the auxiliary counter 6. The trolley then engages a further cam surface of the card holder to move it back to its initial position. A tooth 116 extending from the holder increments the least significant digit of the auxiliary counter which therefore provides a record of the number of complete cycles of recordings made, the final movement of the card holder also re-engaging the pin 152 with the bell crank 160. The increment in the value of the main counter allowable before a particular card must be changed, may be varied by meshing the " locking " pinion (122) with different transfer pinions 22. A further locking mechanism (Figs. 8, 9) is provided to prevent initial rotation of the trolley screw until a card is placed in the tray 40 and the tray pushed firmly home in the machine.

[Classes 38 (iii) and 38 (v).] Travelling to predetermined limits; electromagnetic switches, retarded action of.-The discharge through an electron tube 1, Fig. 1, is stopped and restarted by a switch 17 operating externally of the tube, and a resistance 14 and condenser 10, connected to the grid of the tube, are arranged to ensure against re-starting of discharge for a given period following stoppage. An elevator motor 25, Fig. 3, is supplied from lines L1, L2, L3, through reversing contactors 27, 28, which are controlled by cage switches 31, 32, 33, or floor switches 34, 35, 36, through an electron tube 1. The control circuits include a protective arrangement such as is described in Specification 370,682 so that the circuit of the contactors 27, 28 is interrupted by the tube 1, upon phase reversal or failure of the supply. When the contactor 27 is energised by closure of one of the switches 34-36, a corresponding relay 42, 43, or 44 is energised and is maintained by contacts 27c. At the same time a relay 30 is energised to charge a condenser 10 which, when a stop button 41, or a limit switch on the motor shaft, is operated to de-energise the contactor 27 and open the motor circuit, discharges through a resistance 14 and applies a potential to the grid of the tube 1 such that the tube is prevented fromconducting even though another floor switch be closed. This stoppage of the tube 1 ends with the completion of the discharge of the condenser. The time delay on the tube 1 is not effective when any of the cage switches 31-33 are operated since with such operation the condenser and discharge resistance are short-circuited. Reference has been directed by the Comptroller to Specifications 390,309 and 391,232, [both in Group XXXV.]
