Abstract: 387,855. Safety razors. CAMPBELL, A. G., Sherbrooke, Quebec, Canada. March 16, 1932, No. 7889. Convention date, Aug. 17, 1931. [Class 30.] In a safety razor, the blade 17 is permanently bent along a line parallel to its longitudinal edges, one of the surfaces so formed being inclined to the axis of the handle 10 at an angle between 30-35‹ and the other of said surfaces at an angle between 60-70‹. The cutting edge of the former surface is used for shaving the cheeks and that of the latter surface for the neck and throat. The toothed guard 11 and the clamping-plate 12 are similarly bent. The parts of the guard, blade, and clamping-member of greater inclination are broader than those of less inclination. The usual clamping and aligning pins 14, 16 which are located on the broader part of the clamping-member pass through holes in the corresponding parts of the blade and guard.

Title: Photographic camera
IPC: G03B7/04
Filed: 1960-03-07
Abstract: 937,185. Photographic cameras. AGFA A.G. March 7, 1960 [March 25, 1959], No. 8055/60. Class 98 (1). In a photographic camera having an exposure meter the moving coil galvanometer of which is arranged to be rotated to bring its deflected needle into register with a fixed index within a visible area which is small relative to the total range of deflection of the needle so that only part of said range may be observed at any one time, at least one deflection range boundary indicating means is arranged to be brought into the visible area by movement of the galvanometer. As shown (Figs. 2 and 3), an exposure a meter accommodated in an upper camera casing 3 comprises a photo-cell 7 and a rotatably mounted galvanometer 8 the needle 32 of which is visible through a small window 35 (c.f. Fig. 4). Rotation of the galvanometer for bringing the needle 32 into register with a fixed index 36 is brought about, on rotation of a control cam 30 which is adjusted in terms of light values by diaphragm and shutter speed setting rings 4, 5, by transmission mechanism comprising an axially displaceable control pin 29 engaging under spring loading said cam 30, a rotatable spindle 24 in toothed engagement 27, 28 with the pin 29, a rotatable cam element 18 which is releasably coupled to a crown toothed disc 26 on the spindle 24, and a lever 12 which is pivoted at 16, has a pin 17 at one end engaging the cam element 18, and is engaged at the other end (under loading by spring 11) by a pin 10 on the galvanometer 8. Pins 33, 34 limit the deflection range of the needle 32, and pointers 38, 39 carried by disc 37 attached to the galvanometer 8 indicate the boundaries of this range. The cam element 18 is coupled to the toothed disc 26, under loading of a spring 22, through a tooth 25. Different film sensitivities are set by raising a knob 20 to break the coupling 25, 26 arid rotating the knob with reference to a scale (not shown)-this setting being effected with the ring preferably in an end position. In an alternative embodiment (Fig. 4) the end of the needle 32 is bent over so that it may be seen by reflection in a mirror 51 in the camera viewfinder and a window 52 in a partition 53 is provided with a fixed index similar to 36. Further, there is provided an indicator lever 43, which is pivoted at 42, is normally held out of view by spring 46, and has lugs 47,48 engageable by abutments 49, 50 on the galvanometer 8 so that when either of the limits of the measurement range of the galvanometer are reached a transparent coloured portion 44 of the lever 43 is moved into register with the index 36 and, with the needle 32 aligned therewith.

Title: Improvements in the production of aluminium sulphate
IPC: C01F7/743
Filed: 1928-03-19
Abstract: 312,726. Horsley, G. F., and Imperial Chemical Industries, Ltd. March 19, 1928. Aluminium sulphate.-Bauxite, clay, and other iron-bearing aluminiferous minerals are treated to obtain aluminium sulphate free from iron. The material may, for instance, be treated within a rotary kiln in countercurrent with a stream of gases containing sulphur trioxide or sulphur dioxide and oxygen at a temperature intermediate between the decomposition temperature of aluminium and ferric sulphates, having regard to the partial pressure of sulphur trioxide in the gases. For example a gas containing 7 per cent of SO, may be passed over crude bauxite at 600-750 C. When wet clay is used as initial material it is first dehydrated by the waste gases as it passes along the kiln. Alternatively the material may be treated if desired in a rotary kiln, with gases containing sulphur dioxide and oxygen at a temperature below the decomposition temperature of ferric sulphate, say at 450 C., and be then further heated, say to 650 C., to cause decomposition of the ferric sulphate and formation of aluminium sulphate. A catalyst such as iron to assist the conversion of sulphur dioxide to sulphur trioxide may be added if necessary. Specification 163,348 is referred to.

In a further modification shown in Fig. 4 the limbs 31, 32 of a spring loop are connected py respective pivot pins 38a, 38b to the spade 35 of the fork prong 36. The lug 33 for mounting the wheel axle is carried by a straight offset 40 connecting the limbs 31, 32. Alternatively the lug 33 may form the connecting element for. two separate curved spring rods. Both limbs 31, 32 may function as combined leaf springs and radius arms or one of the limbs may be substantially inflexible.

[Class 20(iii)] A mechanism for a vertically-sliding window comprises a carrier member 6 attached either, as shown, to the window panel, or to a stationary part and housing a volute spring 7, together with a lifting lever 11, which moves angularly as the window is raised or lowered, and is pivoted at one end to the housing at a point 10 displaced from the rotatable hub 8 of the spring, and has the other end displaceably anchored, for example by pivoting to a link 12. A flexible member 16 passing around the hub 8 and connected to the lever 11 causes the spring to exert a pull,on the lever at an acute angle to it. In the form shown, the flexible member comprises a chain 16 attached to a sprocket 15 eccentrically mounted on the spring hub and to a link 18 pivoted to the lever 11. The degree of balance of the window at various positions can be predetermined by giving the sprocket 15 an appropriate cam-like form.

Patent GB-674883-A (GB)
Title: Plasticising cellulose derivatives
IPC: D06M13/35
Filed: 1949-03-31
Abstract: A thermoplastic cellulose derivative is plasticized by treating it while in solid form with an aqueous dispersion of a plasticizer in the presence of a cationic surface active agent. The cellulose derivative may be in the form of flakes, powder, fibres, yarns, or fabrics.  Mixed yarns or fabrics containing fibres of a thermoplastic cellulose derivative and fibres of a non-thermoplastic nature such as cellulose, or of a thermoplastic nature but not of a cellulose derivative, may be treated.  The treated webs or fabrics may subsequently be subjected to heat and pressure to cause the plasticized component to become tacky and so to bond or unite the non-plasticized fibres or yarns, or the fabrics may be used for the production of decorative effects by hot stamping or embossing. Cellulose derivatives may be treated in the flake or like form produced by precipitation or coagulation, and preferably they are treated before drying. Cellulose acetates of various acetyl contents up to the triacetate, and similar esters such as propionates and acetobutyrates, and also methyl, ethyl, and other cellulose ethers may be treated.  For cellulose acetate, the plasticizer may be dimethyl phthalate, ethyl phthalate, triphenyl phosphate, methyl phthalyl ethyl glycollate, or o- and p-toluene ethyl sulphonamides. For cellulose butyrate there may be used dibutyl sebacate, di-2-ethyl hexyl adipate, or diethyl phthalate.  For cellulose ethers there may be used dioctyl or diamyl phthalate, butyl stearate, or methyl ricinoleate.  The cationic surface active agent may be a long chain alkyl pyridinium halide or a phosphonium compound, or it may be a compound obtained by acylating an unsymmetrical dialkyl ethylene diamine with a fatty acid chloride, the product being used in the form of its hydrochloride.  In an example, an aqueous dispersion of dimethyl phthalate is prepared using cetyl pyridinium bromide as dispersing agent.  Cellulose acetate staple fibres are immersed in the liquid at 50 DEG  C. and subsequently removed and dried.  In another example, a fabric containing cellulose acetate yarns and cotton yarns is immersed in an aqueous dispersion of methyl phthalyl ethyl glycollate containing lauryl pyridinium chloride.  The fabric so produced may be used for making laminated fabric or it may be given embossed or similar patterns by heat and pressure treatment.
