Abstract: 969,064. Delivering measured quantities of pulverulent material. SOC. PARISIENNE D'EXPANSION CHIMIQUE S.P.E.C.I.A. Jan. 24, 1962 [Jan. 25, 1961], No. 2727/62. Heading B8N. An apparatus for dispensing measured quantities of pulverulent material to containers comprises a rotatable plate 1 having measuring compartments 3 in a circular row and a fixed annular material magazine 6 arranged eccentrically to the plate so that the compartments pass below the magazine for filling and then pass beyond the outer wall 5; each chamber has a piston 11 which moves upwards to deliver the contents of the compartment to the top of the plate within U-shaped scrapers 16 rotating with and radially slidable on the plate so that they can push the material down shoots 9. The pistons 11 are lowered during filling of the compartments and raised during ejection of the contents by a cam 14 which can be adjusted vertically to vary the volume of the comportments. The scrapers may be spring-loaded and bear on the outer wall 5 of the eccentric annulus so that they move in and out. A support for raising a container 27 into filling position is actuated by a cam 24 and both the support and piston have a yielding connection with their cam followers to prevent damage if a jam occurs; also, if there is no container in place the over-elevation of the support cams a peg into a groove in the piston and prevents it rising. A level-sensing blade may be fitted in the magazine and operate contacts or a mercury switch to control a vibratory duct or motor-driven rotary agitator or distributer in the supply means to the magazine; such supply means may be the container or cans in which the material is supplied.

Title: Improvements in and relating to electric switches
IPC: H01H33/38
Filed: 1938-01-28
Abstract: 514,359. Gas - blast switchcs. BRITISH THOMSON-HOUSTON CO., Ltd. Jan 28, 1938, No. 2826. Void. Convention date, Jan. 28, 1937. [Class 38 (v)] In a gas-blast switch of the kind having mechanism arranged so as automatically on contact-separation to produce a compressed-gas supply from which a blast is directed on to the region between the contacts, the operation of the mechanism is controlled by electromagnetic means including a winding carrying all or part of the current passing through the switch, either continuously or only when the contacts are separated, the winding being so arranged that the energy utilized by the mechanism is derived wholly or partly from said current. In Fig. I, opening movement of contact 4 actuates a locking system which releases a piston 2 of magnetic material, so allowing the stressed spring 6 to move the piston from the left and a 'cylinder 1 into the field of the continuously-energized winding 5, which drives it further to the right and forces a blast of air past (and through, @if desired) the fixed contact 3. Winding 5 may alternatively act on a core on the remote end of the piston rod, Fig. 2 (not shown). In Fig. 4, the piston 2 is fixed and the cylinder 1 is magnetic and movable by the winding 5 in co-operation with the fixed core member 19. The contact 3 is carried by, and moves with, the cylinder 1 so as to provide extra separation. In Figs. 5, 6 (not shown) an independent core acts on the cylinder 1 either directly, or through a spring, respectively, Fig. 7, shows a form in which the magnetic core comprises the piston 2 which is hollow and carries a tube 21 surrounding the movable contact A. This hollow-piston arrangement is also adaptable to a remote core which is connected either directly to the piston 2, Fig. 8 (not shown) or through a spring 14, Fig. 9 (not shown). Fig. 10 shows how the losses due to continuous energization of winding 5 can be avoided by connecting that winding in circuit at the moment of separation only. When closing the switch, contact 4 engages contact 3 and presses it back into engagement with an auxiliary short-circuiting contact 22 for the winding 5, which auxiliary contact is first disengaged on opening circuit. The cylinder 1 is magnetic and carries the contact 3, a spring similar 'to 6 being also fitted. The contacts 3, 22 may, alternatively, be in the form of rings traversed by 4, Fig. 11 (not shown) and in a construction similar to that of Fig. 7, an auxiliary contact 22 engages in the closed position, a conducting part of piston 2 and disengages it in the initial opening movement, Figs. 12, 13 (not shown). The Specification refers also to the use of a short-circuited or main-current carrying winding instead of a magnet core for certain forms of the invention, and to the use with the gas of substances which by expansion produce deionizing gas or vapour.

Title: Improvements in or relating to apparatus for the production of artistic prints and impressions
IPC: B41F1/26
Filed: 1925-02-03
Abstract: 244,943. Gr³nberg, J., and Kahn, Ges., R. Feb. 3, 1925. F l u i d pressure presses.-In a printing-press in which the sheets to be printed are pressed against the printing-surface by an elastric diaphragm forming the wall of a container to which fluid under pressure is admitted, the diaphragm is so mounted that the pressure of the fluid tends to tighten the joint between the diaphragm and the container. The printing-surface may be supported upon a second elastic diaphragm. The printing-plate 18 and the sheet to be printed are supported on an elastic diaphragm 25 closing a pressure-fluid chamber 24 in a bed block 17<1> and pressure is applied to the sheet by a rubber diaphragm 5 closing the bottom 4 of a container 3 to which fluid under pressure may be admitted. The diaphragm 5 is held at its edges by a member 7 loosely mounted on the neck 13 of a screw 8 which may be turned by a key inserted through an opening 12 in the container 3 to force the member 7 downwardly. As the diaphragm 5 stretches under the pressure of the fluid, slackness in the joint is taken up by the member 7 moving under the influence of the difference of pressure on its faces. The diaphragm 25 is held by a frame 26 guided by pins 27 and pressed downwardly by the diaphragm 5. Before the pressure fluid is admitted to the container 3 the block 17<1> is raised by a screw 21, to bring the duct into contact with the diaphragm 5. After printing, the block 17<1> is lowered until rollers 19 carried by it rest on rails 20 and withdrawn laterally. During the rise and fall of the block, the rollers 19 engage vertical guides 23. In another form the printing-plate rests on a solid bed. In a further form, a thick sheet of rubber or rubber and canvas is attached to the diaphragm 5 so as to project below the outer face of the bottom of the container 3 to allow larger printing-plates to be employed.

Title: Improvements relating to fish-dressing machines
IPC: A22C25/08
Filed: 1951-05-21
Abstract: 701.679. Fish - dressing machines. BAADER, R. May 21, 1951 [May 19, 1950], No. 3061/53. Divided out of 701,650. Class 28(2) In a fish-dressing machine in which the tail is gripped and pulled through the machine by the jaws 59 of a tail clamp Fig. 2, a feed trough, Fig. 3, presents the tail to the clamp, the feed trough being accelerated to move faster than the clamp to effect a smooth transfer of the fish. 'The feed trough 71 comprising exit plates 72 &c. is reciprocated on rails 311 by a cam groove and roller 66 swinging a lever 67 about a fixed pivot 310. The trough is also rocked vertically about pivots 312 by a cam slot 313 and roller 86 to tip down the forward end of the trough so that the fish tends to slide out of the trough towards the clamp. The cam slot 313 then tips up the outlet end of the trough to lift it clear of the path of a succeeding tail clamp and ready for the next fish to be placed therein. The outlet end of the feed trough comprises a pair of pivoted plates 72 urged to close by springs but held apart by the thickness of a pair of intervening top and bottom plates 78, 79 held apart vertically by coupled bell cranks 80, 81 controlled by a roller and cam 84, 85. As the trough is reciprocated back to the right, the cam 85 spreads apart vertically the plates 78, 79 so that a fish can be pushed by hand far enough until its tail projects just beyond the plates 72. As the trough is moved forward (to the left) so that 84 clears 85, the plate 78 drops and presses down the tail root of the fish against the plate 79 to bring it to the right height for entering the tail clamp. About the same time the plates 72 are allowed to open (when rods 76 become clear of the slot 77) to allow the fish body to be pulled through by the tail clamp. The tail clamp jaws 59, Fig. 2, are urged together about their pivot 308 by springs 61 but are held open during the time that fixed cams (not described) are in contact with rollers 62 on the moving clamp assembly.
