The front wall 220 is provided with a key 260 which is a dapted to be inserted into the head of the razor in order to release the clamping pressure on the used blade and to align the dispenser correctly such that the new blade can be pushed into the razor head. An aperture 254 is provided in the bottom wall 210 such that used blades can be inserted into the compartment 244. A further aperture 252 is formed in the wall 224 so that the number of blades remaining in the dispenser can be seen.

Abstract: 1,171,399. Moving-bed filters. JOHNSMANVILLE CORP. 19 Sept., 1967 [20 Sept., 1966], No. 42505/67. Heading B1D. [Also in Divisions Cl and F4] Heavy particles are removed from a liquid in a continuous process wherein the liquid is introduced into a chamber 16 and then flowed in countercurrent through a moving filter bed 41, 42 while simultaneously allowing particle settling in chamber 16, the bed 41, 42 being continuously replenished. As described, contaminated liquid enters a chamber 16 at 1 p.s.i.g. through an inlet 18. Owing to the narrowness of an outlet 22, part of the liquid enters a second chamber 44 and passes through the filter bed; the clarified liquid is removed through outlet 39. The bed advances (from left to right in Fig. 2) under the action of reciprocating diaphragms 34, 54. Sprays 50, 52 remove the contaminated end of the bed, which passes through outlet 20, 22 and enters a second filtering device 12 (identical to that just described) at 800-1000 p.s.i.g. Filtrate from this second device 12 is re-cycled via pipe 76 back to the first filtering device. Sludge from filter 12 is sent through chute 78 to an incinerator 14, see Division F4, also Cl, which burns it in an oxygen-poor atmosphere, thus increasing the carbon content; it is returned to the first filtering device at 36 through pipe 80. Thus the filter bed 41, 42 is replenished with reactivated filter material. Propelling the filter bed. Devices 62 determine the pressure drop across the bed and control the rate of reciprocation of the diaphragms 34, 54 accordingly. In a modification, Fig. 3 (not shown) the diaphragms 34, 54 are replaced by a single rotating and rectilinearly reciprocating screw impeller (64). In either embodiment the frusto-conical section of chamber 24 acts as a check valve preventing the filter bed from moving to the left. Filter media. Alternating layers of active carbon adsorbent 41 and sand 42, and flocculating agents (e.g. alum) or ion exchange resins may be used.

Abstract: 915,598. Refrigerating. GARRETT CORPORATION. Dec. 9, 1960 [Dec. 14, 1959], No. 42525/60. Class 29. In a closed cycle refrigeration system having a compressor 1 of a type liable to surging, a condenser 2, an evaporator 4, by-passing means 28, 29 for hot gas leaving the compressor to flow to the low pressure side of the closed circuit to prevent surging, a valve 15 to control and throttle the liquid refrigerant passing from the liquid receiver 3 to the evaporator 4 and to control simultaneously but in opposite sense the flow of hot gas through the by-pass, the valve is actuated by a linear actuator 16 driven by an electric motor 17 controlled by controller 18, the error signal to the controller being derived by a temperature responsive thermistor sensor 24. As shown, by-pass pipe 29 leads to the evaporator inlet, but in a modification (Fig. 1A, not shown), pipe 29 leads to the evaporator outlet, liquid refrigerant being fed through a restriction from receiver 3 to pipe 28 to prevent too high a gas temperature in the compressor inlet. The liquid refrigerant is fed to the evaporator inlet through distributer tube 27. The heating effect due to the hot gas may be greater than the cooling effect of the liquid refrigerant so that the system can act as a heater as well as a cooler. The valve assembly may have a position in which, upon stopping of the compressor, liquid refrigerant in the evaporator strains back to the receiver. Fig. 2 shows an embodiment of the valve 15, comprising casing 31 having liquid inlet and outlet passages 32 and 33 respectively and gas inlet and outlet passages 34 and 35 respectively. The moving member 38 of the valve comprises a spindle for portions of varying diameter extending through sleeves 37 and 42 and has a piston 44 and a reduced portion 45 which control the area of the throttling port 39. The lower end of the valve member 38 carries a cupshaped piston 46 controlling the area of the gas throttling ports 43 and hence controls the flow of gas through the valve. Figs. 5-8 and Fig. 9 (not shown) show other embodiments of a valve, comprising a rotary member within the casing, having a liquid groove and a gas groove on the periphery of the rotating member, these grooves arranged to communicate with the liquid and gas inlet and outlet passages and perform a similar operation to the valve shown in Fig. 2.
