Title: Improvements in or relating to briquetting presses
IPC: B30B11/02
Filed: 1943-01-28
Abstract: 565,676. Hydraulic presses. FLOWERS, P. E. Jan. 28, 1943, No. 1462. [Class 69 (ii)] [Also in Group V] The machine is controlled by an electric circuit. On depression of a starting switch the following sequence of events occurs :- (1) From the position shown in Fig. 1, a charging box 65 is moved by a pneumatic cylinder 75 and piston 73, to the right, and bridges the gap between the plunger 35 and the mould 53. Material A to be briquetted thus falls into the base of the box, which was initially occupied by the plunger, and further material falls from the hopper 64 into the box. (2) The plunger and ejector 54 then move together to the right, conveying the material between them into the mould. (3) When the ejector reaches a shoulder in the mould, it stops, but the plunger goes on to compress the material. During the compressing movement the plunger platen 34 moves away from nuts 62, Fig. 5, on rods 60 connected to ejector plungers 58. (4) The charging box and plunger then retract to the left, but the ejector remains stationary until lost motion has been taken up between platen 34 and nuts 62, whereupon the platen engages the nuts to pull out the ejector. The ejected article falls on to an inclined plate. As the ejector moves leftward an arm 63 thereon operates a valve 48 which admits compressed air to the mould to clean the latter. The plunger 35 is carried by a ram 11 movement of which to the right is initiated by energisation of solenoid 91a which rocks lever 87 to admit hydraulic pressure from pump P through valve 82 and pipes 88, 26 to ports 21 in the head of a stationary booster cylinder 23. After the ram has moved a little way, port 29 in the wall thereof is uncovered and fluid passes from the booster cylinder 23 through conduits 30 to the main area 12 of the ram to exert an increased pressure. The booster cylinder is threaded in the ram casing head at 16, and by turning a square-headed booster cylinder exten. sion 19 the booster cylinder may be adjusted longitudinally relatively to the ram, whereby the time during which the booster cylinder alone acts on the ram may be varied while the ram is moving, the ejector also is moved by pressure fluid through pipes 81, 88, 26a, 93 acting on pistons 58 and yoke 57 to which the ejector is fixed. When a predetermined pressure has been built up in pipe 26, a switch in a tonnage control valve 97 opens, whereupon the electrical, hydraulic and pneumatic con. nections reverse and the charging box, plunger and ejector move to the left and stop. The electric circuit may be so set that another cycle begins automatically. If the tonnage control valve fails, cam 128 on the ram opens a switch LS3, the connections being thus reversed. The stroke of the ram may be adjusted by varying the position of the cam 128 on the platen or the position of the switch LS1. On over-heating, an oil temperature switch breaks the electric circuit and stops the machine. Specification 519,824, [Group XXV], is referred to.

Filed: 1950-01-23
Abstract: 672,431. Photo-electric control system. TECHNICOLOR MOTION PICTURE CORPORATION. Jan. 23, 1950 [Feb. 5, 1949], No. 1700/50. Class 40 (iii). [Also in Group XXXV] The brightness of a lamp G, for printing a positive film strip P from a negative strip N, is controlled according to a pre-arranged programme (such as will ensure correct exposure for the several different scenes contained in the negative) recorded as perforations on a card 36 which is intermittently advanced in correspondence with the movement of the strip past the lamp, the arrangement being such that each row of perforations (transverse to the line of travel of the card) comprises two sections relating, respectively, to different parts of the programme and the card reading means is rendered responsive to the two sections in succession. The lamp brightness is governed by a series of resistors X, any of which may be short-circuited by relays 37-42, the coils of which are energized in accordance with the perforations in the operative section of a row. For this purpose each relay coil is energized by an amplifier 127-132 when a photo-electric cell 217-222 associated therewith is illuminated by a light source 215 or 216-one for each section of a row. The number of cells corresponds with the maximum possible number of perforations in each section of a row and light which may emerge from corresponding perforations of the two sections is directed to the appropriate cell by light-conducting rods 224. The light sources 215, 216 are rendered alternately effective by an Eccles-Jordan trigger circuit 209 which is switched from one stable condition to the other by a photo-electric system 207, 208 each time the cell 207 responds to the passage of marks 205 on the negative N past an optical system 201-206. A relay 43, controlled from the trigger circuit through an amplifier 210, steps the card forward each time light source 215 is effective.

Title: Improvements in the stemming of fruits such as grapes
IPC: A23N15/02
Filed: 1951-01-24
Abstract: 675,720. Grapes &c. detaching from stalks.. STANDARD CANNERS & PACKERS, Ltd. Jan. 24, 1951 [Jan. 31, 1950], No. 1817/51 Class 28 (ii). Grapes are removed from their stems by clamping the stem between jaws 11, 12 and vibrating the cluster to detach the berries from their pedicles. The amplitude of vibration is about ¥ inch and has a frequency of about 11 cycles per second. The vibrating may be done mechanically or electromagnetically. A post 4 carrying the jaws 11, 12 is oscillated up and down when it is pressed up by a compression spring 6 against one end of a cross lever 9 rocked by a cam 15, Fig. 1 (not shown). After a suitable number of vibrations an arm 18 is pulled down about its pivot 19, 20 by mechanism from a cam 31 whereby the arm 18 depresses the oscillating post 4 against its spring 6 and moves it out of range of the action of the rocking lever 9 whereby the oscillations stop. This is done by the cam 31b, Fig. 2, rocking a lever 38 which pulls down a guided rod 21 attached to the far end of the lever 18 against the compression spring 31. This downward movement of the rod 21 also opens jaw 12 by means of an upper collar 34 which rocks lever 35 to trip and pivot the extension 37 of the pivoted jaw 12. Later the jaw 12 is allowed to clamp shut on a hand-presented stem when the lower collar 34 is raised against the lever 35 which action is done by the spring 23 when allowed by the cam surface 31a coming against the roller end of lever 38, so that the spring 13 can close the jaw 12 against the jaw 11. The grapes drop on to a conveyer.

Title: Improvements in or relating to photographic developing materials and methods
IPC: B01J23/86
Filed: 1948-01-22
Abstract: 680,423. Photographic developing materials. INTERNATIONAL POLAROID CORPORATION. Jan. 22, 1948 [Feb. 8, 1947], No. 1972/48. Drawings to Specification. Class 98 (ii). A composite sheet material for treating an exposed photosensitive material comprises an image-carrying layer as of cellulosic film or paper, preferably baryta paper, having an impervious coating such as wax, plastic material, lead or tin foil but preferably microcrystalline wax, and a further coating containing in solution a film-forming material, a developer for exposed silver halide, and a silver halide solvent capable of creating soluble silver complexes with undeveloped portions of the silver halide, this further coating having the physical characteristics of a solid film and the chemical characteristics of a solution. In use the sheet material is pressed on to an exposed silver halide emulsion layer for the purpose of development and one-step production of a positive image, the latter being formed on the sheet material by effect of the silver halide solvent on unexposed silver halide; during pressure some of the moisture of the coating is absorbed by the gelatine of the emulsion layer and dissolved film-forming material precipitates, so that, on separation of the emulsion layer from the sheet material after an interval of one or two minutes, the remaining moisture evaporates rapidly and a dry positive image results. For storage the sheet material may be wound into a roll with the impervious coating outermost so as to prevent evaporation, and such roll may have its ends sealed as by addition of impervious strips, or by provision of marginal adhesive portions so that each layer of the roll is sealed to the next layer. The image-forming coating, as set out in two examples, comprises sodium carboxymethyl cellulose, sodium hydroxide, sodium thiosulphate, citric acid, sodium, sulphite and hydroquinone dissolved in water. Other film-forming materials, such as sodium alginate, hydroxyethyl cellulose, starch or gum, may be used. A white pigment such as titanium dioxide to form a background for the positive image, and zinc sulphide to precipitate silver from silver complexes formed by the silver halide solvent may be included in the imageforming coating.
