Title: Machine for packing articles in rows into a case or carton
IPC: B65B67/02
Filed: 1974-07-10
Abstract: 1475281 Packaging machines ASKEYS Ltd 10 July 1974 [12 April 1973] 17689/73 Heading B8C In a machine for packing articles, such as nested ice cream cones, in side by side rows into cartons B, articles C are manually fed in rows on to endless conveyer 11 by an operator for transfer to a median location of frame 10 where a fixed number of articles in each row are received by a reciprocating sliding carriage 16 which carries the articles to a packing station S for insertion into a carton B by a pusher plate 23 mounted on a reciprocating slide 24. The flow of articles on conveyer 11 is arrested by vertically reciprocable cam operated stop 15 while carriage 16 moves to station S. Carriage 16 has four end blocks 16b in transverse pairs and runs on slides 16a, second and third stops 18 and 19 being mounted on carriers 31, 31a vertically slidable on rods 30 extending from blocks 16b under the action of cams 18a, 19a on cam plates 32 mounted on a piston-rod 17a which reciprocates the carriage. Stops 18, 19 are alternately raised and lowered as the carriage takes up its two positions, and their spacing determines the number of articles to be packed in a carton; this spacing is variable. Pusher plate 23 is pivoted on a crosshead slide 24 and has down-turned pusher blades 25, the plate being raised and lowered under cam actions as slide 24 is longitudinally reciprocated so that blades 25 may engage the rear of articles C when the carriage is in the forward position to push the articles into a carton. Articles on the carriage 16 in rows are laterally pressed together by cam-operated plates 40 which may have a joggling action. Cartons B are placed on packing table 20 by a second operator who removes them when filled. Reciprocating members are pneumatically operated with valve controlled timing.

Abstract: 1,184,893. Foamed polymers containing isocyanate groups. IMPERIAL CHEMICAL INDUSTRIES Ltd. 11 April, 1967 [22 April, 1966], No.17730/66. Headings C3C and C3R. Foamed polymers containing an isocyanate ring structure are prepared by reacting in the presence of a blowing agent and a catalyst for the polymerization of isocyanates, a polyol of M.W. greater than 300 and a crude diisocyanatodiarylalkene composition containing 5 to 70% by weight of polyisocyanates of functionality greater than two, in such amounts so as to provide at least 1À7 equivalents of isocyanate group for each equivalent of active hydrogen. Preferred diisocyanatodiarylalkane compositions are the diisocyanatodiphenylmethane compositions which may be optionally halogenated. Conventional linear and branch chained polyethers or polyesters are preferably used. The blowing agent may be water and/or inert low boiling liquids especially halogenated hydrocarbons. Catalysts which may be used are strong bases, e.g. quaternary ammonium hydroxides, alkali metal hydroxides and alkoxides, alkali metal salts of carboxylic acids, certain tertiary amines and non-basic metal salts of carboxylic acids, e.g. lead octoate. Mixtures of the above catalysts with conventional catalysts, used in the formation of polyurethanes, may be used. The reaction mixture also may contain surface active agents, plasticizers, flame-retardants, fillers and antioxidants.

Filed: 1940-12-17
Abstract: 541,400. Starting oil engines. CHAPMAN, C. W., and PERKINS, Ltd., F. Dec. 17, 1940. No. 17797. [Class 7 (iii)] To facilitate starting a compression ignition engine, the air drawn through the induction pipe 12 is heated by means of a fuel spray 13 ignited by a device 17, which may be a wire heated by electricity, supplied by a battery 18 and switch 19, or a spark device with a coil and contact-breaker. The battery may also operate the starting-motor. 21. The fuel may be supplied from a tank 16 by a hand pump 15, and may be the normal fuel or some more ignitable fuel such as paraffin. Instead of a pump and sprayer, a carburetter device holding a limited quantity of fuel may be arranged so that the fuel is drawn in with the induction air and ignited by the heater.

Title: Automatic speed control systems for alternating-current motors
IPC: H02P25/18
Filed: 1950-07-17
Abstract: 672,507. Control of A.C. motors. HUWYLER, A. July 17, 1950. [Feb. 7, 1950] No. 17839/50. Class 38 (iii). [Also in Group XXXV] When the speed of a three-phase induction motor 11 is below a predetermined value, series resonant circuits which are'tuned to the supply frequency and which respectively comprise elements 13, 14 and 13a, 14a are connected in two of the supply-lines to the motor. Upon the motor speed exceeding the set value, contacts 18 close to energize relay 17 and open contacts 16, 16a, so introducing capacitors 15, 15a, into the supply circuit. The resonant. circuits are thereby detuned, the impedance of the motor primary circuit is increased, and the motor speed is reduced. In this manner the contacts 18 are continuously operated to maintain the motor speed substantially at a value which may be adjusted by member 20. In the arrangement of Fig. 2 (not shown) each resonant circuit comprises a condenser and an iron-cored choke the primary winding of which is loosely coupled with an auxiliary winding. The two auxiliary windings are connected in series and are adapted to be short-circuited by the speed responsive contact and cause de-tuning of the resonant circuits when the motor speed becomes excessive. In both arrangements the contacts 18 may be arranged to open when the motor speed rises above the limiting value. The speedresponsive contact may control a rotary relay which is coupled to a rotary condenser in each resonant circuit. Parallel-resonant circuits mav be employed which are automatically tuned to the supply frequency when the motor exceeds the required speed, so providing a high impedance which reduces the motor current. The resonant circuits may comprise parallelconnected inductors or capacitors, de-tuning being effected by disconnecting one of these elements.

Abstract: 658,317. Polishing precious and other stones. HOCHSZTEIN, L. M. July 8, 1949, No. 18068. [Class 60] A machine for grinding, polishing and cutting diamonds, precious or semi-precious stones and the like comprises a main frame 30, Fig. 1, a pivoting frame 8 adapted to be set to polishing position and swung into horizontal, position, a rotatably-driven polishing disc 31 adapted to be moved in a horizontal plane, means for raising and lowering the polishing disc, a stone-holding member 2, Fig. 2, carried by the pivoting frame, means for longitudinally and rotatably adjusting the stone-holding member; a table 21, Fig. 3, carried by the disc assembly, and a telescope and collinator 24 fixed on a goniometer adjustable on the table. The pivoting frame can be set to the required polishing angle in relation to the disc 31 and also to a horizontal position for inspecting the stone 1 through the telescope, and the stone-holding member can be rotated to present successive faces of the stone to the disc. The holder 2 is secured to a shaft 3 supported in a hollow mandrel 7 and slidably keyed to a worm wheel 17. The latter is engaged by a worm 16 provided with a handwheel 36, Fig. 1, to enable the shaft 3 to be indexed. Vertical movement of the shaft 3 with respect to the mandrel 7 is limited by two screwed stops 19, 20 which co-operate with a bridge member 18 secured to the worm drive casing. The mandrel 7 is connected with a sleeve 6 by a spherical mounting 10, 11, and arranged to be angularly adjusted therein by means of screws 5. Vertical movement of the sleeve 6 may be obtained by means of a handwheel 13 with which it is in screw-threaded engagement, the handwheel being rotatably mounted on an outer sleeve 9 by a collar 12. This latter sleeve is secured to the pivoting frame 8 which is mounted by pins 33 on the main frame 30.
