Patent GB-583717-A (GB)
Title: Loading regulator
IPC: B65G65/00
Filed: 1944-11-21
Abstract: 583,717. Loading vehicles. DUNCAN, A. W., and MINING ENGINEERING CO., Ltd. Nov. 21, 1944, No. 23148.

Title: Liquid dispensing apparatus
Inventor: DOWNIE GEORGE
IPC: G01F11/04
Filed: 1961-06-27
Abstract: 934,456. Delivering measured quantities of liquid. GASKELL & CHAMBERS Ltd. June 14, 1962 [June 27, 1961], No. 23159/61. Class 106 (5). A liquid dispensing apparatus comprises a cylinder 10 connected to a liquid supply source via passages 17 and to an outlet pipe 11, a free piston 12 movable in the cylinder, and plug valve 13 mounted in supporting members 14 at each end of the cylinder, each plug valve and its supporting member being provided with coacting abutments 18, 19, the abutment 19 being fixed and the abutment 18 being movable on engagement therewith by the piston at the end of its stroke, the arrangement being such that the two abutments are so disposed relative to each other as to prevent movement of the valves sufficient to effect reversal of the piston until the latter reaches the end of the stroke and displaces the movable abutment relative to the fixed abutment. The movable abutment is in the form of a pin 18 and the fixed abutment is formed by a plate 19 secured to the end supporting member 14. In operation, pressurized liquid, such as beer, is fed through passages 17, valve 13 and into the cylinder 10 where it forces the piston 12 to the right as shown in Fig. 1, thereby dispensing the beer on the other side of the piston through the outlet pipe 11. The piston is prevented from being reversed until it has completed its stroke by means of the pin being in alignment with the abutment plate 19; when the piston has completed its stroke, it depresses the pin against the action of the spring so that the head of the pin passes into a recess formed in the plate, thereby permitting the plug valve to be rotated by the handle 15; a similar action takes place when the piston is moved to the left. In order to prevent the plug valve, if the handle 15 is removed, from being forced out of the end supporting member 14 due to the reaction of the spring-loaded pin 18 against the piston, a manually-operable lever 20, Fig. 4, pivoted on the supporting member 4, is arranged to be engaged in a groove 21 formed in the plug valve.

Abstract: 588,727. Screw and nut gearing. AUTOMOTIVE PRODUCTS CO., Ltd., and HAYMAN, B. M. Nov. 27, 1944, No. 23650. [Class 80 (iii)] [Also in Groups XXIX and XXXVII] An electric motor reciprocates a member (e.g. a piston valve) through screw and nut mechanism and actuates switches so that at the end of travel the motor is stopped by a reverse torque and then disconnected from the supply. The motor spindle 11 (Fig. 1) rotates sleeve-nut 12 supported by a ball-thrust bearing 13 in insulating block 14, thereby reciprocating screwed rod 23. The latter has an enlargement 19 slidable in a bore 17 in block 14 and carrying on a transverse pin 20 rollers which run in slots in block 14 to prevent rotation of rod 23. The enlargement 19 also engages one or other of the plungers 57 and 58 projecting into bore 17, thereby actuating limit switches mounted on the block. Direction-responsive switches on the block are actuated according to the direction of rotation, by arm 45 which is rotatably free on sleeve 12 but gripped by spring-pressed washers 48 and 49. The rod 23 reciprocates the member through sleeve 25 and balls 35 pressed resiliently into groove 36 by encircling spring 37; this allows sleeve 25 to be reciprocated independently by sufficient force to force balls 35 out of groove 36. Specification 572,775, [Group XXIX], is referred to.

Automatic apparatus; continuous apparatus for developing.-Two or more automatic cameras, which are embodied in the front portion of a chamber and may have a common drive, are adapted to be used with a single developing apparatus to which the photographs are hand conveyed. The developing apparatus comprises two motor driven endless link chains connected at intervals by rods 14, Fig. 4, to which the prints are attached by clips 15. The prints are carried through a series of tanks, the time of immersion being regulated by horizontally displacing the wheels guiding the endless chains, to a drying chamber containing a heater and a fan, and are removed from the conveyer and delivered to the sitter through a lightproof lock by the attendant. A bladed wheel 18 is adapted to stir the baths. The clips, Fig. 5, which have interchangeable springs 19 for seizing the prints 16, are carried at such a height that only the springs 19 dip below the liquid level 20-21. The attendant uses new springs 19 for each print to prevent stains arising from contamination of the baths. The cameras and developing apparatus are enclosed in a light-proof chamber large enough to allow one or more attendant's to charge and supervise the developing apparatus. The Specification as open to inspection under Sect. 91 (3) (a) states that the photographs may be automatically conveyed from the photographing machines to a single automatic developing machine.

A ledger card has a strip of magnetic tape on its rear surface, the position of the recorded data on the tape being used to control the feeding of the card to the next line to be printed. After manual insertion, the card operates a pair of switches, if correctly aligned, and is driven by feed rollers past a read/record head towards a printing station. Clock pulses derived from the NRZ recording on the tape are counted until a number signifying the end of the record is reached, this being used in conjunction with the next pulse from an emitter coupled to the feed rolls to stop the card feed. Alternatively, if the card is new and not yet recorded on, actuation of a limit switch by the leading edge of the card stops the feed. An eject command from a key or associated computer causes reverse drive of the feed rolls, and after allowing for line-feed displacement of the card, the new data is gated from the computer memory to the read/write head.
