Title: Improvements in and relating to wrapping machines
IPC: B65B25/16
Filed: 1932-06-21
Abstract: 405,344. Slicing bread &c. TRIGGS, W. W., 57, Lincoln's Inn Fields, London.- (American Machine & Foundry Co. ; 511, 5th Avenue, New York, U.S.A.) June 21, 1932, No. 33765/33. Divided on 404,976, [Group XVII]. [Class 5 (i).] A wrapping machine, in which a loaf of bread or like article is moved through a slicing mechanism before arriving at the wrapping mechanism, is arranged so that the slicing mechanism may be rendered inoperative, and the machine may be used to wrap sliced or unsliced articles. Safety devices for preventing incorrect operation are provided. The slicing mechanism, shown in an inoperative position in Fig. 2, comprises a frame 92 mounted on rubber cushions on bars 100 extending between and fastened to guide rods 101 adapted to slide in the frames 20, 21. The entire mechanism may be moved from the position shown to an operative position in front of an elevator plate 57 by the action of a hand crank 106 on a threaded shaft. The blades 86 are arranged in two series, carried respectively by two frames, in such relation that the blades on the rear frame 88 enter the loaf shortly after the rear edges of the series on the forward frame have passed into the loaf, so that the side pressure of each series is sustained by the thickness of two slices of bread. The series are staggered to the extent of the thickness of one slice. The upper ends of the frames are pivotally supported by guide shoes 91 sliding in guides on the frame 92, and at their lower ends are connected to eccentrics 93, 94 oppositely mounted so that the two series of blades carried by the frames are oppositely reciprocated. An independent motor 96 drives the shaft 95 so that the operation of the slicer is separate from that of the wrapping mechanism. The slicer is positively locked in one or the other position by the engagement of a spring lever with one of two grooves in one of the guide rods 101. The motor is provided with a switch which prevents it from being started when the slicing mechanism is in the inoperative position. The loaf is pushed through the slicer by a pronged pusher and adjustment of the slices can only take place when the pusher is fully withdrawn so as to prevent damage to the blades. In order to prevent adjustment of the slicing mechanism when the pusher member is in an advanced position between the blades, the safety device shown in Fig. 5 is employed. A locking lever 285 engages one of two grooves 293 in the lower surface of one of the guide rods 101, corresponding to the operative and the inoperative positions. A spring 292 normally holds the lever 285 in the locking position ; and the lever 289, and consequently the lever 285 cannot move from this position except when a notch 296 and stud 291 are in register. The notch is on a disc 295 on the main shaft 38 and is so positioned that it registers only when the pronged pusher is fully withdrawn from the blades. A lifting device carries the loaf from the slicer table to a delivery table.

Title: Improvements in or relating to the separation of the constituents of organic-inorganic addition compounds
IPC: C07C51/487
Filed: 1936-12-11
Abstract: Organic constituents are freed from their addition compounds with inorganic halides by adding a halide of Na, Zn, Al, Cu, Pb, Fe or Sn, or calcium oxide.  The inorganic halide and added metal halide, which must be different, form an addition compound, and the freed organic constituent may be removed as by distillation, extraction, or absorption.  Where the inorganic halide is volatile, e.g. a boron halide, calcium oxide or a non-volatile halide may be added, the addition compound formed being heated to recover the volatile halide. Addition compounds which may be treated include those of boron fluoride with acetic, propionic or other aliphatic acids or esters, dimethyl or diethyl ether, and methyl, propyl, butyl, isobutyl or higher alcohols.  In addition to boron halides, inorganic halides specified are those of Al, Sn, Ti, Si and S.  In examples, (CH3COOH)2.BF3 is heated to not more than 250 DEG  C. with sodium fluoride or chloride, acetic acid distilling.  Specification 486,669 is referred to.  The Specification as open to inspection under Sect. 91 comprises the use of alkaline earth halides as the added metal halides and includes a further example employing calcium fluoride.

Title: Carpet backings and a process for their preparation
IPC: D04H3/16
Filed: 1963-08-30
Abstract: A non-woven fabric suitable for use as a tufted carpet base is prepared by applying a polar lubricant to a non-woven self-bonded fabric comprising randomly disposed continuous filaments of a polymer from the group of isotactic polypropylene, linear polyethylene, linear copolymers of ethylene or propylene with up to 25% by weight of other copolymerizable monomers, and melt blends of said polymers and copolymers with up to 25% of other polymers, e.g. atactic polypropylene, branched polyethylene, polyisobutylene; the filaments possess a birefringence that is at least 40% of the maximum birefringence and the average edge bond count of the fabric, i.e. the number of bonds appearing on an edge face of the fabric per one hundred filaments, lies between 30 and 80.  The polar lubricants include methyl hydrogen polysiloxane, 2-ethylhexyl silicate, 2-ethylhexyl sebacate, acetyl 2-ethylhexyl citrate, refined coconut oil potassium oleate, potassium n-octyl phosphates and mixed n-octyl-hydroxy-ethyl esters of phosphoric acid.  The lubricants may be applied by spraying, padding, roll coating and in the form of dispersions or solutions in water or an organic medium, and lubricant pickup is usually from 0.3% to 10% by weight of the fabric.  The fibrous web may be air-laid and is bonded by exposing the web to a non-solvating fluid, e.g. steam, at a bonding temperature Tx which is within 45 DEG C. below the crystalline melting temperature of the filament while simultaneously applying light compressive forces to the surfaces of the web to prevent shrinkage of the filaments of more than 20% and to prevent loss in birefringence of more than 50%.  The bonding temperature Tx is that temperature within the 45 DEG C. range which gives the best tear resistance in the bonded product and is determined for any given material by experiment.  The compressive restraint on the sheet is usually maintained till the temperature is at least 5 DEG C. below the bonding temperature.  The sheet or web may contain up to 25% of other filamentary materials, such as glass, metal, or other organic or inorganic materials.  Minor amounts of fillers, stabilisers, pigments and the like may also be included. The web may be pressed and heated to emboss or otherwise treat its surface after the bonding process.  In examples described the fabric was tufted in conventional manner with nylon carpet yarn at a spacing of 4 to 15 stitches per inch with tuft rows at 0.188 inch separation and tuft height of 0.44 inch.  The tufting needle diameter may range from 0.1 to 0.18 inch.  A latex adhesive may be applied to the back of the tufted carpet and dried to hold the tufts in place or a secondary backing fabric of the same type as the primary fabric but without the polar lubricant, laminated thereto by means of the adhesive layer.

Title: Improvements in or relating to frictional lighters
IPC: F23Q2/08
Filed: 1946-11-22
Abstract: 633,558. Frictional lighters. MEITNER, B. Nov. 22, 1946, No. 34620. [Class 75 (iii)] In a frictional lighter an oscillatable member 16 (screen and snuffer arm) driving the friction wheel 14 through a pawl, is operated from a manually operated actuating member 26 through a resilient member e.g. a leaf spring 29 so that during the initial movement of the actuating member a relatively small movement of the oscillatable member takes place and the resilient member stores energy which is suddenly released at a later part of the operating movement. The actuating member 26 is pivoted to cheeks 11 secured to the fuel reservoir 1 and is provided with an angle piece 27 holding one end of the leaf spring 29 the other end of which is located in an angle formed by parts 17, 24 of the oscillatable member 16 and is provided with depending claws keeping the spring in position. The point of abutment of the spring 29 with the oscillatable member 16 is just below the line joining the axis 13 of the oscillatable member 16 to the point at which the spring abuts the actuating member 26. On manually rotating the actuating member the leaf spring which may be slightly curved before assembly bends downwards and later unbends to accelerate the turning of the friction wheel; a pin may be provided on the actuating member to prevent the spring from bending upwards. The oscillatable member 16 is returned by a tension spring 22 secured between the actuating member and the oscillatable member. The mechanism is housed in a casing 31, Fig. 4, provided with a window 32 normally closed by the top 18 of the oscillatable member. The actuating member 26 may slide within the casing 31 instead of being pivoted therein.

Title: A hydraulic copying milling or like machine
IPC: B23Q35/18
Filed: 1945-12-20
Abstract: 646,495. Copy-milling machines. TURCHAN, M., and WALKER, C. Dec. 20, 1945, No. 34649. [Class 83 (iii)] In a milling-machine having horizontal longitudinal- and cross-feeds hydraulicallycontrolled as described in Specification 646,494 and employing a direction control valve and reversing valve as described in Specification 646,493, the exhaust fluid from both the feed cylinders is returned through a common connection to the throttle valve in the tracer head. Fluid exhausted from the particular cylinder under constant-pressure control is returned to the tracer through the directional control valve 24 and pipe 47 and from the particular cylinder under tracer control through either pipe 22 or 23, and ports 20, 38 or 21, 49 according to the direction of feed and the position of the tracer valve 15, and thence through pipe 39. The two flows are joined together at 41 and are led by a pipe 42 to a lower port 43 of a throttle valve integral with the tracer valve. Normal up or down control movements of the tracer valve only partially restrict the opening 44 leading to port 45 and a pipe 46 leading back to a hydraulic unit 11 and merely slow down both feeds while a change of direction is taking place in the tracer-controlled cylinder. If, when a point of considerable change of direction in the pattern is reached, where the tracer-controlled and constant-pressure fluid supplies to the cylinders should be interchanged by operating the control valve 24, and the operator fails to do so, the tracer and throttle valve is raised sufficiently to cut-off the opening 44 from the port 45, stop the exhaust from both feed-cylinders and stop all feeding movements. Adjustable spring- loaded valves 40, 48 are fitted in the return pipes 39, 47 to cushion the return flows and prevent vibration. Metering valves 51, 52 are fitted in the pipe 23 for tracer-controlled fluid and in the constant-pressure fluid return pipe 47 so that either or both feed-cylinder movements may be speeded up or slowed down as required.

Abstract: 798,684. Valves. WARD, L. T. Nov. 30, 1954 [Aug. 16, 1954], No. 34717/54. Class 135. [Also in Group XXVIII] A discharge valve for a container for discharging substances under gaseous pressure is adapted to permit charging of the container with the substance and the propellant. Fig. 2 shows a housing 11, that is attached to the container, in which slides a member 19 that has an axial bore 23 from which leads a passage 24 that is normally closed by a resilient sealing ring 18. The member 19 is pressed upwards by a spring 32 and when depressed, the chamber 21 communicates through the passage 24 to the outlet. The lower end of the member 19 is reduced at 27, 28 to enter a dip tube 12, the part 27 leaves sufficient clearance with the tube 12 to permit gas only to pass to the chamber 21 before the member 19 seats in the seating 31 at the top of the tube 12. The contents of the chamber 21 is dispensed at each actuation of the member 19. To fill the container, a resilient member 37 having a cavity 38 and a V-shaped slot 40 in the skirt, is inserted in the bore 23 and a filling head 35 is applied to the container so that the substance flows through the protruding part of the slot 40. After filling, the member 37 is pressed into the bore 23 by a rod 42 and held in position by the rib 37x. Fig. 6 shows an arrangement where a member 47 having a slot 50 is pressed into the lower end of the bore 23. Fig. 10 shows an alternative form in which a ball valve 59 normally closes a bore 23x in the member 19 which is formed of two parts 26, 55. Specification 798,683, [Group XXVIII], is referred to.
