Abstract: 1,173,652. Food for animals. GILLETTE CO. 3 Jan., 1967 [6 Jan., 1966; 7 Dec., 1966], No. 291/67. Heading A2B. [Also in Divisions C3, C6 and D1] In a process for treating keratinous materials, such as animal horns or hooves, to produce nutritive agents for animal consumption, the materials are brought into contact, at a temperature up to 50‹C., with a solution, e.g. an aqueous solution, containing (a) a dissolved nucleophilic compound in the form of a water-soluble sulphite, and (b) a dissolved, mono-functional blocking agent capable of reacting with a thiol to form a thioether, said blocking agent being an alkylene oxide, aziridine, or olefinic compound, and said materials being contacted by a single solution of solutes (a) and (b), or with a solution of solute (a) or (b) to which is then added a solution of solute (b) or (a). At least 1.0 millimole of the nucleophilic compound and at least 1.0 millimole of the blocking agent may be used for each gram of keratin in the keratinous materials. The nucleophilic compound may be sodium sulphite.

Title: Improvements in or relating to presses more particulary for shaping plastic materials
IPC: B30B1/26
Filed: 1957-01-07
Abstract: 836,834. Mechanical presses. MASCHINENFABRIK WEINGARTEN A.G. Jan. 7, 1957 [Jan. 10, 1956], No. 567/57. Class 87(2). [Also in Group XXII] A press, particularly for shaping plastics such as glass-fibre reinforced polyester resins, comprises a work table, a ram, crank drive mechanism for driving the  r am in an idling stroke whereby the ram may be positioned for a shaping operation, and is characterised by means acting independently of the crank drive to impart a slow working stroke to the press whilst the crank drive for the ram is stopped in the dead centre position of the cranks. As shown, a double-crank press comprises a work table 1, columns and 3 connected at the head of the machine by a cross member 4, and a crankshaft 6 journalled in the cross member 4 and carrying pitmans 7 which act on the ram 5 at two points. The invention may be performed in any one of five ways, in each of which the ram 5 is lowered on the idling stroke to the bottom dead centre position of the cranks and stopped. (i) A worm wheel 11, united with a spindle nut 9 threaded on the spindle of a head 8 to which the lower end of a pitman 7 is pivoted, is rotated by a worm 12 operated by a motor, not shown, through a drive common to both pitmans. The desired slow working stroke is thus given to the ram 5. (ii) The bed 25 is raised by mechanical means, not shown, to give the equivalent of a slow starting stroke to the ram. (iii) Fluid is forced under pressure by a pump 15, through a pipe 13, to the underside of pistons 10, the reaction thus moving the .ram downwards. In this arrangement a differential piston 19 controls the working pressure, since the fluid . pressure forces up the piston against air in a cylinder 20, till a relief channel 21 is uncovered. Air may be admitted to, or released from, the cylinder 20 to adjust the limiting working pressure. At the end of the pressing operation a valve 17 is opened and fluid is returned, from beneath the pistons 10 to a sump by admitting air under pressure to a balancing cylinder 23 and thus raising the ram 5, either before or during the succeeding idling stroke of the cranks. Pressure fluid can also be forced from beneath the pistons 10 by raising the bed 25 by means of fluid pressure in cushions 26. (iv) In a modification of (iii), there may be a separate differential piston for each pitman, thus enabling the pressure over the surface of the ram to be adjusted. (v) The bed 25 is raised by admitting pressure fluid to the cushions 26, to give the equivalent of the required slow working stroke. The desired pressure may be sensed by a contact manometer or by a piezo-electric gauge.

Title: Improvements in or relating to machines in which assemblies of predetermined numbersof similar packets of articles are automatically formed
IPC: B65B19/32
Filed: 1961-01-06
Abstract: 913,679. Discharging endless conveyers. SCHMERMUND, A. Jan. 6, 1961 [Jan. 29, 1960], No. 656/61. Class 78 (1). [Also in Group XVII] Defective packets in a line being forwarded to assembly means &c. are rejected from the line and replaced by other packets from a reserve supply. The detecting means is conventional and is not described. In one embodiment, packets are forwarded by a conveyer 50 to a stacking channel 45 into which they are thrust by an arm 47. A pusher 68 raises the stack so that the uppermost packet may be thrust by a further pusher 56 on to a member 43. The member 43 forces it into an assembly device 36 to form a group 52 and the group 52 is transferred to a further channel 42. If a faulty packet is detected prior to its entering the channel 45, it is still fed on to the pusher 68 but the latter is prevented from operatiug by solenoid means 63, 65, 101. The next packet fed in by the arm 47 ejects the faulty packet on to a shoot 53 and at the same time a pusher 38 thrusts a reserve packet from the base of a magazine 61 on to the top of the stack in the channel 45. The pusher 56 transfers it to the member 43 and operation continues normally. Alternatively the spare packet may be fed directly on to the member 43 (not shown). In another embodiment (Figs. 1-5, not shown), the faulty packet is thrust directly off a line on a conveyer, by a reserve packet.

Title: Improvements in and relating to coin-freed delivery machines
IPC: G07F11/16
Filed: 1929-01-09
Abstract: 325,662. Chubb, G. C. P., and Summers, L. F. Jan. 9, 1929. Coin action, mechanical-connection and multiple-coin.-One or two articles at the bottom of a pile y are ejected according to the size of the coin inserted. The pile y is supported by a table h beneath which are slides i, j, each having an upstanding tongue i<1>, j<1>, and a depending leg i<2>, j<2>. The tongue j<1> protrudes higher than the tongue i<1> and the leg i<2> extends lower than the leg j<2>. The tongues i<1>, j<1> pass through a slot in the table. An inserted coin passes down a shoot a into a pocket b on a slide having a handle c<1> protruding from the side or front of the machine. When a small coin is in the pocket b and the handle c<1> is pulled the coin x engages the leg i<2> and the slide only is moved, the tongue i<1> thereon pushing the lowermost article through a delivery aperture. A larger coin will engage the leg j<2> so that both slides i, j, are moved to deliver two articles. The length of the slot in the table for the tongue i<1>, j' is such that the latter cannot pass completely from under the remaining articles which are supported by the actuating tongue i<1> or j<1> during the delivery and return movements. During the delivery stroke the coin x rides over ratchet teeth on a fixed bar g as described in Specification 285,609. A trip lever q pivoted to the bar g prevents return of the coin pocket unless a full delivery stroke has been made. The handle and the delivery pocket are returned by a spring e, and, at the same time, a projection b<1> on the pocket engages the tongue i<2> to return the slides. During delivery the bottom of the shoot a is closed by a wire coil m<1> which normally is held clear of the shoot by the back of the coin pocket. If the coin pocket is empty sliding movement thereof is prevented by one end of a spring-controlled pivoted lever n, Fig. 8, the other end n<2> of which protrudes into the path of the slide i. The delivery aperture is normally closed by a spring flap k. Specifications 7722/88 and 13220/90 also are referred to.
