Title: Improvements in or relating to shoe trimming machines
IPC: A43D8/32
Filed: 1924-03-08
Abstract: 234,911. British United Shoe Machinery Co., Ltd., Gouldbourn, J., and Goddard, J. W., (United Shoe Machinery Corporation [partly]). March 8, 1924. Cutting out lining panels; trimming.-Relates to machines for trimming upper material of a bottomed shoe, of the kind in which a support carrying a knife or an upper supporting member. or both, is so dimensioned that it can enter well into the shoe; and consists in machines adapted to cut out panels of lining material which have been left to support "bar" or "cut out" uppers. A rotatable mounting is provided for the knife or the support, so that the support does not impede the trimming of curved portions of the work; and two co-operating cutting members are provided, such as a knife and anvil, one inside and the other outside the shoe. A vibrating pointed knife may be used. Fig. 1 shows a machine with a reciprocating rotatable knife 4, mounted in a sleeve 7 carried by a middle sleeve 12 which can slide but not rotate in an outer sleeve 13 capable of a part rotation in a bearing at the end of an arm 3 adapted to enter well into the top portion of a bottomed shoe. The knife is reciprocated by a block 19 on a crank on a driven shaft 21, dirt being excluded by a rotatable guide in an adjustable cap 18 which forms the support for the upper. The knife co-operates with an anvil 5 having lips 61, Fig. 3, which enter between the upper and lining and constitute a gauge. The anvil is carried by a stem 29, Fig. 1, adjustable vertically and normally depressed by a spring 37. The anvil is raised, to permit insertion of work, by a treadleactuated lever 40. For cutting curved portions of the work, or as necessary, the anvil and knife may be simultaneously swung through an angle by a handle 55 on a spindle 47 carrying two pulleys 45, 48 which are connected to pulleys 42 on the anvil mounting and the sleeve 13, respectively, by steel bands pinned to the rotatable members. The bands are tensioned by pointed screws 53. When a seam is encountered the upper support 17, 18 descends against the pressure of a spring 16. Fig. 4 shows a modified machine wherein the support 78 entering the shoe is rotatable, it being carried on ball bearings 158. The support carries a shear ring 68, Fig. 5, co-operating with a knife 62 having a point and a cutting edge 66. The knife is reciprocated by an arm 96 normally latched to an arm 100 oscillated by a crank 106. To guide the knife and support waste material, a spring plunger 162, Fig. 5, is mounted in the ring 68. A knife guard and gauge 70, Fig. 7, has a rounded surface 74 and lip 72 engaging the upper, and a flange 76 to protect the operator's fingers. To permit insertion of work, a treadle raises a plunger 124, Fig. 4, which first frees the latch and then raises the arm 96 by a pin 126. A screw 84 on the knife-carrying bar engages a stop 138 and raises the gauge with the knife. To slightly raise the gauge 70 when a seam is encountered a knee lever working between adjustable limits raises an arm 146 on the gauge-carry. ing rod.

Classes 64(1) and 64(3) A heating appliance adapted for use in a domestic fireplace comprises an oil burner 23, the combustion gases from which pass through one path in order to heat air and through a second path defined wholly or in part by the-existing fireplace structure, in order to heat water. The combustion gases may heat the air and water simultaneously, the available heating gases being apportioned between the two paths by means such as a damper 25. The air heating path comprises an externally finned flue 33 around which air circulates by convection before passing into the room through openings 39 in an external casing 1, the air to be heated entering the casing at or below the floor level. The water heating path may comprise the existing back-boiler flue (Fig. 1, not shown), or the burner gases may flow over a coil 49 (Fig. 4) connected to the existing back-boiler 47, the existing flue around the boiler being blocked by means such as indicated at 48. Alternatively the gases may flow through a duct 26 passing through the boiler as shown in Fig. 2. In a further form described the gases flow over a tube coil connected to hot water storage tanks or radiators (Fig. 5, not shown). The damper 25 may be actuated by means responsive to the temperature of the room being heated, and the oil flow to the burner may be governed by the water temperature.

Abstract: 668,594. Educational appliances. MATTHEWS, H. March 13, 1950, No. 6200/50. Class 146 (ii). A device for demonstrating refraction in a uniformly spherical lens comprises four rods &c. hinged at a, b, c, d to form a collapsable rectangular frame, and a fifth rod which is hinged at a and has a pin e engaging a slot f, g in the rod b, c. The opposite rods are of equal length, and the rod a, e is the same length as the rods a, d and b, c. The ratio between the lengths of the rod a, d and the rod a, b is equal to the ratio of the speed of light in air and the speed of light in the material of the lens (Á). The hinge a may comprise a pencil or other marker. In use, a horizontal line is drawn on a sheet of paper &c. to represent the axis of a uniformly spherical lens, the base rod c, d, is fixed along the line with the hinge d placed over a dot on the line representing the optical centre of the lens, and the frame is then swung counterclockwise about the base so that the pencil at a inscribes a quarter circle. This quarter circle represents the surface of a segment of a sphere which subtends 90 degrees. Externally to this curved line a number of parallel lines, which are also parallel to the axis, are drawn to represent rays of light incident on that surface. If the frame is now rotated about the base, the rod a, e indicates the direction of each ray refracted within the lens body.

Title: Improvements in and relating to the production of compositions having antiseptic, disinfectant, germicidal, insecticidal and like properties
IPC: C11D1/00
Filed: 1937-03-03
Abstract: A compound having antiseptic, disinfectant, germicidal and insecticidal properties is prepared by heating together salol and thymol in the presence of a small quantity of an aromatic carboxylic acid, e.g. benzoic or phthalic acid as catalyst or condensing agent. Sufficient heat is applied to liquefy the mixture.  Preferably, 3 parts by weight of thymol are employed to 1 part of salol, and about 1 per cent of benzoic acid.  The mixture is heated to 37-40 DEG  C. and crystallizes on cooling.  The compound may be solubilized in water with an alkali soluble salt of cinnamic acid as described in 491,567, or using soaps or sulphonated fatty substances.  It may be dissolved in paraffin containing radio-activated substances to yield a therapeutically valuable, antiseptic solution, or in terpineol to yield disinfectant solution.  A solution in a non-aqueous volatile solvent may be sprayed into the air to form a dry mist.  Fabrics may be impregnated with solutions of the compound, or with suitable solvents it may be employed as an internal disinfectant. The compound may also be used for destroying vermin.  It is thought that the compound may be methylisopropyldiphenyl-p-hydroxybenzoate.ALSO:A compound having antiseptic, disinfectant, germicidal, and insecticidal properties is prepared by heating together salol and thymol in the presence of a small quantity of an aromatic carboxylic acid, e.g. benzoic or phthalic acid as catalyst or condensing agent.

Title: Meat-curing compositions
Inventor: SAIR LOUIS
IPC: A23B4/023
Filed: 1965-02-16
Abstract: A meat curing composition consists essentially of sodium chloride, an ene-diol compound, and curing salt consisting of alkali-metal nitrite, or a mixture of alkali-metal nitrite crystals and alkali-metal nitrate crystals, or a fusion of alkali-metal nitrite and alkali-metal nitrate, or any mixture of the above, the content of at least one of the mutually reactive components, which are the nitrite salt and the ene-diol compound, being present without the other and with at least a portion of the sodium chloride as components of aggregated particles apart from the remainder of the composition, whereby reactive contact between the reactive components is minimised.  The ene-diol compound is preferably a water-soluble salt of an isomer of ascorbic acid, e.g. sodium erythorbate.  In the preferred embodiment, part of the sodium chloride is mixed with and formed into aggregated particles with sodium nitrite and sodium nitrate and these agglomerated particles are then mixed with sodium erythorbate and the balance of the sodium chloride.  The stability of the composition may be further increased by the inclusion of an alkaline agent such as sodium bicarbonate.
