Title: Improvements in and relating to rotary razors
IPC: B26B19/16
Filed: 1919-10-30
Abstract: 152,211. Jones, S. P. Oct. 30, 1919. Razors.-In a rotary razor of the barrel or cylinder type having a number of blades mounted in a mechanically rotated carrier head, the carrier is rotatable in opposite directions so that the beard may be shaved in opposite directions. The double-edged blades 36, Figs. 8 and 9, are clamped to the cylindrical carrier head 26 by gauge plates 37 having headed studs 38 passing through apertures in the blades and head and engaged by key-hole slots 39 in plungers 40 slidingly mounted in the head. Longitudinal lather-accumulating pockets 28 are arranged in the head between the blades, and communicate with the periphery of the head by ports 32 and slots 34; the blade edges overhang the slots 34 and lie flush with or slightly below the surface of the head. The head is secured to a shaft 20 by a spring latch 29 fastened in one of the pockets 28, the shaft being carried in a sleeve 12 and driven by gearing in a lateral offset support 11. Fig. 1, carried by a tubular handle 10, through which the driving-shaft 25 extends. A cylindrical guard housing 14 provided with a hinged cap 15 is fastened to the sleeve 12 and is formed at one side with a longitudinal slot, through which the blades operate. Apertures may be arranged adjacent the slot; or the slot may be bridged by diagonal ribs. The razor may be used without the guard.

Filed: 1963-07-06
Abstract: 1,043,283. Lubricating. G. E. ADAMS & CO. Ltd. July 6, 1963. No. 26865/63. Heading F2A. A liquid flow indicator has a sight chamber with an upper inlet for visual drip-feed of liquid into the chamber and a lower outlet whereby liquid may be drawn by suction from the sight chamber to an atomizer or atomizer chamber. In an embodiment, an oil-flow indicator has a sight-chamber 1, Fig. 3 (not shown), with an inlet 2 through which oil 3 drips. The oil collects in a reservoir 4 in the chamber which is connected, via an outlet 5 and a passage 18, to a chamber 6 of an atomizer 7 which, along with the indicator, is formed in a transparent body 9. The chamber 6 has tightly fitted therein a member 20 which has a main bore 22, a reduced bore 23, radial ports 24, and is reduced externally so as to form an annular space 21 with the wall of the chamber 6. In use, oil, supplied to a passage 16 which is connected to the inlet 2, drips into the reservoir 4, from where it is drawn, through the passage 18, into the annular space 21. Pressurized air is supplied to the bore 22 of the member 20 via a passage 19 in the body 9 and is passed to the reduced bore 23. Oil also enters the bore 23 via the radial ports 24 and an oil-mist is formed through an outlet 25 of the member 20. In addition to the oil-flow from the inlet 2 being indicated by the drips of oil 3 the functioning of the atomizer and spray is checked by observation of the oil level in the reservoir 4.

Title: Improvements in and relating to methods and means for Stitching or Sewing Flexible Fabrics
IPC: D06B1/00
Filed: 1966-06-17
Abstract: 1,154,382. Coating apparatus. UNION SPECIAL MACHINE CO. 17 June, 1966 [18 June, 1965], No. 27167/66. Heading B2L. [Also in Divisions B5 and D1] Organic stiffening agent in its liquid phase is applied to a part of a fabric workpiece to be stitched, the impregnated part is cooled to solidify the agent, the stiffened part is stitched in a sewing machine, and the stiffening agent is removed from the sewn fabric by vaporising. In Fig. 6 liquid paradichlorethylene is supplied by a pump 160, driven by a motor 161, and via a pipe 162 to a closed tank 156 in which the stiffening agent is maintained in the liquid phase by heater elements 157. The approach of a workpiece 20r supported by a conveyor belt 12, to tank 156 interrupts a beam of light between a lamp 90a and a photocell 91a to energise a solenoid valve 159 for opening a nozzle 158 adapted to spray the liquid upon the workpiece. A pressure-responsive switch 164, mounted in tank 156, maintains a constant pressure therein by starting and stepping motor 161. The stiffening agent is solidified by contact with a chilled surface. In a modification, Fig. 1, the liquid flows by gravity from a tank, in which a constant level of the heated liquid is automatically maintained, on to the workpiece through an orifice controlled by a solenoidoperated valve. In the arrangement of Fig. 7 a workpiece passes between a pressure roller and an applicator roller partly immersed in liquid stiffening agent. In Fig. 9 the foldedover edge 193 of a workpiece 20w, clamped between plates 181, 183 hinged together at 185, projects into aligned notches 186, 187 formed in said plates, and is impregnated with liquid stiffening agent by contact with an absorbent pad 200. The latter projects from a trough 196 which is supplied with liquid via a heated conduit 202, and solids is rigid with hinged plate 204 adapted to be raised and lowered for engaging and disengaging pad 200 with edge 193. The plates 181, 183 are conductive to prevent the spread of liquid thereunder. The impregnated edge 193 is stiffened by cool air from a nozzle 212.

Gas. supplying by meter; price-changing mechanism.-In a coin-freed gas-meter of the kind in which the coin is inserted through a slot in a front indicating-disc to couple a rotary carrier to a toothed quantity wheel and the disc is adjustable to vary the position of the slot according to the price of gas, in order to allow the disc 1. Fig. 2, to be adjusted without unfastening screws &c. it is formed with gear teeth 2 engaged by a worm enclosed in a easing 4 and formed on a spindle 8 so that by turning the spindle the disc 1 is set in relation to a pointer 11 and locked in position. The spindle 8 having a milled head 12 extends into the cash-box casing 9 and can be turned only when the cash-box is removed. A flat 13 on the head 12 co-operates with a hinged flap 14 to ensure that the disc must indicate a definite number of units before the flap can be turned down and the cash-box replaced. The flap may be locked so that the coin-collector cannot adjust the price-change disc; in this case the flap 14, Fig. 6, has a side plate 16 with a hole 17 adapted to register in its locking position with a hole 18 in the casing 9 and receive a sealed screw 20. In a. modification the worm is turned by a special key inserted through a hole in the casing 9. This keyhole may be closed by a separate hinged plate adapted to be locked and sealed.

Title: Improvements in and relating to amylose sponges and gauze
Inventor: RUTENBERG MORTON WOLF
IPC: C08J9/30
Filed: 1960-08-09
Abstract: An amylose sponge is obtained by foaming and gelling a dispersion of amylose.  The term amylose includes a whole starch which is composed of at least 50% amylose or mixtures of whole starch with at least 50% of amylose.  The sponges may be obtained by:- (1) Dispersing amylose in water containing 15 to 50% of an alkali such as an alkali metal hydroxide or a quaternary ammonium base, stabilizing with the addition of any alkali-resistant non-ionic, anionic or cationic surfactant such as "Pluronic" (Registered Trade Mark) F68, Tetronic 908, Igepal CO-880, sodium dodecyl benzene sulphonate and soap and then inflating by adding ammonium oxalate, ammonium gluconate, dibasic ammonium citrate, ammonium chloride, or dibasic ammonium phosphate, or by blowing in an inert gas such as nitrogen, or by the action of acetic acid or citric acid on a carbonate or bicarbonate. The sponges may be washed with distilled water and then with acetone, isopropanol, ethanol, or methanol and finally dried.  The product can absorb 10 to 25 times its own weight of water.  A plasticizer such as glycerol or diethylene or triethylene glycol may be applied in the form of a solution in ethanol or propanol by spraying into the dried gauze.  (2) Dispersing the amylose in water in an autoclave or jet cooker at a temperature above 160 DEG C. and then stabilizing by adding formaldehyde and sodium carbonate solution optionally in the presence of a sodium phosphate buffer.  The aerated, stabilized dispersion is cast to the desired shape and gelled by exposure to ammonia, sulphur dioxide or gaseous aliphatic amines. (3) Dispersing the amylose in water at a temperature above 160 DEG C., cooling to 95 DEG C., adding a foam stabilizer and then aerating by beating for 3-7 minutes.  After casting into the desired size and shape the sponges are gelled by being allowed to cool for 2-3 hours at room temperature, or by being placed in a refrigerator for 30 minutes.
