Abstract: 1381441 Moulding food patties HOLLYMATIC CORP 11 April 1973 [14 April 1972] 17454/73 Heading B5A In a hopper and plunger apparatus for moulding patties of raw meat or other food wherein a mould plate 20, Fig. 5, is reciprocable to bring its mould cavity 19 into communication with a chamber 12 through which the food is forced by the sequential reciprocation of a plunger 17, the hopper is provided with a rotary feeder 27, Figs. 2 and 4, which urges the food through an opening 14 in the hopper bottom to a passage leading to the chamber 12. The feeder 27 includes a rotary shaft 32 with bars 33, 34 at opposite ends carrying rods 35, 36; the shaft 32 is operated in successive increments of a complete revolution by a linkage mechanism 37, 56, Fig. 1, such that during retraction of the plunger 17, i.e. to the right from the position shown in Fig. 5, following a feed and compression stroke, the feeder is rotated through an increment. The linkage mechanism is driven by a motor 38 and includes a link 40 driven by a shaft 41 and drivingly connected by links 42, 43, 45 to a strap 57 which carries a cross-head 58 from which depends a toothed rack 59 engaging a pinion 60 on the shaft 32. The strap 57 is drivingly connected by a pin 50 with a horizontal reciprocated rack 46 to which the mould plate is attached whereby retraction of the mould plate to a position where the moulded patty is removed by a knock-out device 52 produces an increment of movement of the feeder 27; return movement of the rack 46 and mould plate causes the rack 59 to slide over the teeth of the pinion 60 without driving it. The rack 46 is drivingly connected by a pinion 47, with a further horizontal reciprocated rack 48 carrying the plunger 17. The passage leading from the opening 14 in the hopper base includes a reciprocable agitator (74), Fig. 6, not shown, comprising arms adjacent the passage side walls interconnected by a cross-member and driven by the plunger 17, whereby food is disloged from the side walls, and prevented from bridging the opening 14.

Title: Improvements in or relating to dishwashing machines
IPC: A47L15/06
Filed: 1956-06-06
Abstract: 795,332. Dishwashing machines. DISHMASTER APPLIANCES, Ltd. June 6, 1956 [June 8, 1955], No. 17530/56. Class 138(1). A dishwashing machine controlled by an electric timing motor is characterized in that the timing motor is automatically stopped during the delivery of water, through metering means, to the machine and automatically restarted after the delivery of water. The machine is of known type e.g. having an impeller rotatable in the bottom of a wash tub to throw water upwardly over dishes therein, and the electric timing motor 1 operates cams (not shown) to open and close contacts 2, 3 and 4 to control the sequence of operations in known manner. The water metering means comprises a water supply valve 5 operated by a solenoid 7 and time delay means comprising an adjustable clockwork time lag mechanism 11 having an armature 17 and spring 13, and a time lag solenoid 15. When the solenoid 15 is energized the mechanism 11 is armed through the medium of a lever 16 pivoted at 19 and a switch 18 is closed. When the solenoid 7 is energized the valve 5 is opened and a switch 10 is also opened by a lever 9 pivoted at 9a. The lid or cover of the machine operates a switch 22. In operation the contacts 2 are closed, by a manual control handle which mechanically moves the cams, so that the motor 1 is energized, the contacts 2 remaining closed until the end of the sequence of operations. When the contacts 3 close the solenoid 15 is energized to arm the mechanism 11 and close the switch 18. When the contacts 3 again open and the contacts 4 close, the solenoid 15 is de-energized but the switch 18 is delayed in opening, by the mechanism 11. Thus the solenoid 7 is energized to open the valve 5 and open the switch 10 to stop the motor 1. Finally the switch 18 opens to de-energize the solenoid 7, so that the switch 10 closes and restarts the motor 1.

Title: Improvements to washing and hydro-extracting machine
IPC: D06F37/08
Filed: 1943-10-27
Abstract: 573,674. Washing and drying machines. CRANNY, J. E. Oct. 27, 1943, Nos. 17705/43 and 3724/44. [Class 138 (ii)] [Also in Group II] In a washing and drying machine of the kind in which a cylindrical perforated drum 6 is rotated or oscillated in a container 9 adapted to contain washing liquor, a removable clothes divider 40 is adapted to be inserted in the drum when the latter is to be rotated at a high speed for drying the clothes, this divider comprising a number of vanes 40, 41 radiating from an axle 39 removably supported within the drum. In the construction shown the vanes comprise inner parts 40 fixed to the axle 39, and outer parts 41 sliding within the inner parts and pressed outwards by springs (not shown), the extremities of the outer parts having clips 42 adapted to engage steps or beaters 10 fixed or the drum 6. The drum axle 11, 12 is mounted in bearings 13 in standards 14, and is driven by an electric motor 35 either (1) with a lowspeed oscillatory motion through two belts 17, 18 and a clutch 16 for washing purposes, or (2) with continuous high-speed rotation through a belt 52 and clutch 49. The clutches 16, 49 are simultaneously controlled by a bar 45 slidable in and rotating with the drum axle 11, this bar being normally pressed to the left, as shown in Fig. 3, to keep the clutch 49 disengaged and the clutch 16 engaged. When the clothes divider 40 is inserted in the drum its axle 39 engages a fixed pin 43 at one end and at the other end pushes in a pin 44 fixed to the bar 45 so that the latter is moved to the right to engage the high-speed clutch 49 and disengage the oscillatory clutch 16. Thus the highspeed drive can only be engaged when the clothes-divider is in place. The oscillatory drive is obtained from the motor shaft 34 through bevel gearing 31 and worm gearing 27, the worm wheel having fixed thereto a toothed sector 25 which during the first part of each revolution gears with a pinion 23 driving a double belt-pulley 15 through a belt 18 in one direction, and during the remainder of each revolution gears with a pinion 26 which drives the pulley 15 in the opposite direction through a second pinion 21 and a belt 17. As a safety measure 'the motor circuit may be interrupted by the opening of a lid 59 of the machine casing 60. The'lid 59 may be locked automatically when the drum is rotating, by means of a centrifugal governor 61 acting on a locking bar 68. The drum axle bearings 13 may be mounted in rubber'or other resilient rings 64 in order to reduce vibration. When articles have been washed they are divided into equal lots of the same number as the divisions of the clothes-divider, so that the high-speed rotation does not cause lack of balance. Large articles, such as sheets and blankets, can be laid inside the periphery of the drum and held against the beater steps 10 by the resilient pressure of the vane clips 42. The drum is provided with a door 7. The liquid in the container 9 is heated by electric heating elements or by gas burners 37 enclosed in a casing 38.

Title: Improvements in and relating to the manufacture of derivatives of thiazolidines and of cysteine
IPC: C07D277/06
Filed: 1945-07-11
Abstract: Thiazolidine derivatives of the general formula <FORM:0595958/IV/1> (wherein R1 and R2 represent alkyl radicals, R3 hydrogen or an alkyl or aryl radical, which may carry substituents and R4 hydrogen or an alkyl radical), or the corresponding lactones, are manufactured by treating a thiazolidine derivative of the general formula <FORM:0595958/IV/2> with ethylene oxide or an ethylene halohydrin. When ethylene oxide is used, the reaction is advantageously effected in the presence of a solvent and of boron trifluoride as condensing agent, whereby the lactone is formed at higher and the free hydroxy acid at lower temperatures, the former being convertible to the latter by shaking with cold baryta solution whilst the reverse charge is effected by mild dehydration, e.g. by the action of acetic anhydride.  The products are converted into cysteine derivatives of the general formula <FORM:0595958/IV/3> by rupturing the thiazolidine ring by hydrolysis on heating with strong hydrochloric acid or a chloride of a metal which has an insoluble sulphide (e.g. with aqueous mercuric chloride followed by decomposition of the resultant complex with sulphuretted hydrogen).  In examples: (1) isopropylidenepenicillamine (R1 = R2 = R3 = R4 = CH3) is heated in a sealed tube in suspension in chloroform containing ethylene oxide and a solution of boron trifluoride in ether, yielding the lactone; (2) the product of (1) is heated with hydrochloric acid to produce N-hydroxyethylpenicillamine hydrochloride; (3) 2 - phenyl - 4 : 4 - dimethyl - 5 - carboxythiazolidine (prepared from benzaldehyde and b : b -dimethylcysteine) is treated at 0 DEG  C. with ethylene oxide in chloroform in the presence of ethereal boron trifluoride, yielding the corresponding N-hydroxyethylthiazolidine derivative; (4) the product of (3) is converted into its lactone by warming with acetic anhydride; (5) a  - ethyl dihydropenicilloate - I <FORM:0595958/IV/4> is treated as in (3); (6) the product of (5) is treated as in (4). Specifications 584,918 and 585,413 are referred to.

Title: Improvements in and relating to fluid-operated motors for windscreen wipers
IPC: B64C1/14
Filed: 1940-12-17
Abstract: 545,916. Windscreen wipers ; liquid-pressure engines. ACROTORQUE CO. Dec. 17, 1940, Nos. 17780 and 17781. Convention dates, May 22 and Oct. 5. [Class 69 (ii)] [Also in Group XXIII] A windscreen-wiper motor of the kind in which a double-ended piston slides in a cylinder closed at both ends and supplied with fluid by poppetvalves actuated by the piston is constructed with spring toggle devices for operating the piston. As applied to the oscillation of windscreen wipers for aircraft by means of oil under pressure which is supplied by the fluid system for operating the undercarriages, the input pipe for the oil leads by passages 14, 16, 18 to valve chambers 20 from which the oil is' directed by valves 26 alternatively to either end of a cylinder 60 in which moves a piston rod fitted at each end with a piston 52. With each valve 26 is associated a valve 42 which when open connects one end of the cylinder to exhaust. There are two pairs of valves 26, 42 and the valves 42 are operated by the motion of the piston rod, and the arrangement is such that as each valve 42 is opened the corresponding valve 26 closes under spring action. As shown the piston has completed its movement to the left and the left-hand valve 42 is closed and the left-hand valve 26 open to connect the pressure fluid to the left-hand end of the cylinder so as to start the movement of the pistons to the right. The shaft 58 of the windscreen wiper is oscillated by a rack 54 on the piston rod and a pinion 56, and eccentrics 66 operate the valves 42 by means of lever arm 74 which is rotated by a spring-controlled toggle mechanism comprising a link 68, lever 70 and spring 78 so as to give a snap-over movement to the valves 42 opening and closing the other. The exhaust from the cylinder leads to a sump 64, and the cylinder is fitted with a liner 60 formed with grooves 62 at its extremities which connect via passages 36, 46 to the valve. In a modification, Fig. 5, the toggle mechanism is actuated directly by the piston rod, and controls a cam 88 which acts upon thimbles 82 upon which act springs 80 which with the cam 88 in the piston shown act upon the righthand valve 42 with a greater pressure than a spring 50 acts upon the corresponding valve 26 so that the right-hand end of the cylinder is connected to exhaust through a hole 84 and other passages as in the first modification. The lefthand valve 26 is, however, open and the corresponding valve closed, and the hole 84 is closed by the thimble. A single motor may operate four wipers arranged in conjunction with an aircraft cockpit having a four-panel windscreen. The Specification as open to inspection under Sect. 91 also describes a windscreen wiper now forming the subject-matter of Specification 545,989, [Group XXIII]. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to sheet separating and forwarding machines
IPC: B65H11/00
Filed: 1955-06-20
Abstract: 789,239. Feeding sheets. BACKHOUSE, H. T. June 14, 1956 [June 20, 1955], No. 17797/55. Class 100(1) Sheet - forwarders:- In apparatus for separating sheets from the top of a pile and moving them on to a conveyer embodying a table pivotally mounted on the apparatus for up and down movements, power-operated means is provided for effecting the raising of the table and controlling the lowering thereof. The invention is described as applied to the apparatus disclosed in Specification 774,875, wherein sheets are separated and forwarded on to a tape conveyer 68 having a feed-on roller 67 mounted on a shaft 66 pivotally and removably mounted in bearings 166 adjacent the sheet pile. The conveyer 68 includes a table 69 having side frame members 103 supported on rollers 105 carried by arms, such as 102, secured on a cross-shaft 100. Rotation of the shaft 100 to raise the conveyer 68 and table 69 about the shaft 66 is effected through a system of gearing and a clutch driven from the same electric motor which effects the raising of the sheet pile. This motor is rotated in one direction or the other on depression of one of two switches, and limit switches are provided on the shaft 100. The drive from the motor to the primary and secondary pile hoisting means is through one of two clutches 122, 123 which can be engaged when a pivoted lever 128 is rocked in one direction or the other when a rod 134 is slid axially on the actuation of a handle secured to a sleeve having a helical cam slot engaging a pin on the rod 134. In neutral position these two clutches are inoperative, and the rod 134 energizes the circuits for the movements of the conveyer table; a third clutch 140, in the drive to the shaft 100, is engaged by the rod 134 when it is moved to its neutral position, The side frames 60 of the apparatus have extensions 150 with upwardly-directed forks 152, and corresponding positions the frames 103 of the table have downwardlydirected forks (or holes). By raising the table 67 to the chain line position shown, and inserting a bar 156 in the registered forks, and then lowering the table, the rod 156 will act as a fulcrum for the table and conveyer and the roller shaft 66 will be lifted out of its supporting hooks 166, thus facilitating access to the tapes and rollers of the conveyer. A second bar 157 may be placed across the tops of the extensions 150 and engaged by hooks 159 on the frames 103 near the other end of the conveyer. In a modification, where frame extensions 150 are not provided, a link acts as a tie between the shafts 66, 100, and pivoted abutments are arranged on the frames 103 and can be swung into operative position to act as stops for the rollers 105. Thus, as the previously raised table 69 is being lowered and the rollers 105 meet the abutments, the arms 102, the frames 103, and the link between the shafts 66, 100 constitute a rigid triangle which rocks downwardly about the shaft 100, and so raises the shaft 66 from the hooks 166.
