Title: Apparatus for pointing bristles of brushes
IPC: A46D9/02
Filed: 1927-06-07
Abstract: 287,359. Izawa, R. June 7, 1927. Brush apparatus; band apparatus; disc apparatus.-A device for pointing bristles of brushes automatically is provided with a rotatable bristle carrying member and a rotatable abrading member having several pins to which abrading material is adhered, the direction of relative rotary movement of the two members being changed at will. The carrying member 1, Fig. 1, and abrading member 5 may both consist of rotating wheels. The holding means for bristles may consist of a channel 2, Fig. 7, and a spring 3 in the periphery of the wheel or means may be constructed in a separate block 23 pivoted to the wheel. Around the abrading whee are pins 6 to which abrading material such as emery powder is adhered. The abrading wheel is fixed to the frame, and the carrying wheel is carried on a bearing 7 caused to slide in the frame by a screw 8. The wheels can be driven in either direction by suitable driving means. Brush bristles 9 are brought by the screw 8 into the zone of the pins 6 which are rotated first in one and then in the other direction. If the bristles are held in the block 23, Fig. 7, they become inclined by the action of the pins 6 which then act more effectively. In a modification, Fig. 3, three abrading wheels 5', 5<2>, 5<3>, act together on the brush carrying wheel 1. In another modification, Fig. 4, an abrading belt 15 replaces the abrading wheel and a brush carrying wheel. In another modification a brush carrying wheel has the abrading wheels on opposite sides of it. The abrading wheels are turned in opposite directions and the carrying wheel is operated by a screw so as to be operated upon by either one wheel or the other. In a further modification each brush holding means is arranged to revolve on its own axis and consists of a cylindrical socket 25, Figs. 10, 11, formed in a block 23 and a brush holder 26 carrying a brush 9<1>, and having on the outside a groove 27 and a number of pins 28. The holder is rotatable, the groove 27 engaging a screw 29. The holder has set screws 30 bv which to fix the brush. A projection on the frame of the machine is so situated that projections 28 touch it when the wheel rotates. In this way round brushes receive even abrading action.

Patent GB-729568-A (GB)
Title: Improvements in or relating to the preparation of soaps
IPC: C11D1/46
Filed: 1952-06-23
Abstract: Hard compositions suitable for toilet use contain (1) a transparent alkali-metal soap, (2) a triethanolamine soap of a fatty acid of at least 18 carbon atoms, and (3) an excess of triethanolamine of 1-2 mols. per mol. of fatty acid in the triethanolamine soap.  The excess of triethanolamine is said to be combined with the triethanolamine soap in the form of an ether, and equations are given showing the reactions which are believed to occur.  The compositions may also include an alkyl sulphonate, an alkylaryl sulphonate or a sulphated fatty alcohol.  The compositions may be made by mixing a transparent alkali-metal soap with a fatty acid of at least 18 carbon atoms, e.g. stearic or oleic acid, and triethanolamine in a proportion of 2-3 mols. per mol. of fatty acid, and heating the mixture to 100-120 DEG C. until a homogeneous product is obtained.  Alternatively, a transparent alkali-metal soap may be mixed with a triethanolamine soap of a fatty acid of at least 18 carbon atoms and with triethanolamine in a proportion of 1-2 mols. per mol. of fatty acid in the triethanolamine soap, and the mixture is then heated to 100-120 DEG  C.  As a further alternative, a vegetable or animal fat or oil is saponified with excess caustic soda at 100-120 DEG  C. in the presence of triethanolamine, and a fatty acid of at least 18 carbon atoms is then added in such proportion that 2-3 mols. of triethanolamine are present for each mol. of fatty acid not required to neutralize the excess of caustic alkali.  Suitable oils and fats for use in this modification are olive oil, castor oil, palm-kernel oil, cocoanut oil and beef tallow, but mixtures containing about 30 per cent. of castor oil are preferred; addition of a fatty acid of at least 18 carbon atoms to the oil or fat may be advantageous. Examples are given in which (1) a mixture of a transparent alkali-metal soap, stearic acid, triethanolamine and sodium lauryl sulphate is heated at 110 DEG  C. until it is homogeneous, and the product is made into cakes or bars; (2) a mixture of beef tallow, cocoanut oil, castor oil, caustic soda solution and triethanolamine is heated at 100-110 DEG  C. until saponification is complete, and stearic acid is then added and heating is continued until a homogeneous product is obtained, which is formed into cakes.

Title: Improvements in or relating to the utilization of a plasma of ions to produce high temperature
IPC: H01J17/14
Filed: 1956-05-23
Abstract: 823,072. Discharge apparatus. ZENITH RADIO CORPORATION. May 23, 1956 [May 23, 1955], No. 15917/56. Class 39(1). [Also in Groups XI and XXXV] High temperatures are produced in a gaseous medium by confining a plasma of ions in a concentrated magnetic field, the plasma developing a field-free region within the magnetic field. The plasma may be formed by a spark discharge, which may be d.c. or oscillatory, and the magnetic field may be formed by a pair of coils which produce fields in aiding or opposing relationship. The magnetic field, e.g. of 10<SP>7</SP> gauss, may be produced in 10ÁS pulses and a spark discharge of up to 9ÁS duration generated after the initiation of each magnetic field pulse. Suitable pulse generating and voltage triggering circuits incorporating delay lines are described. In Fig. 1, the coils 55, 61 are flat single turn conductors 55, 61, which are integral with rings 47 forming part of the walls of the container. The rings 47 are separated by rings of insulation 45. Gas is admitted to the container under pressure through a duct 9 and evacuation is through a duct 35. The electrodes comprise a fixed electrode 25 and a spark plug 27. An observation window, comprising a quartz or glass disc 21 is held in place by a hollow screw against a gasket 19, e.g. of copper or synthetic resin material. The coils may be connected in series or in parallel. In Fig. 6, cylindrical coils 115, 115<SP>1</SP> are formed from a single sheet or two sheets joined together (see Group XXXV), and are integral with flat leads passing transversely through the container wall. The container may be of stainless steel coated with gold, silver or copper to reduce electrical losses on the surface may be made highly resistant to reduce magnetic losses. The apparatus has application to spectroscopy, or to the production of nitric oxide from nitrogen and oxygen, or amomnia from nitrogen and hydrogen.

Title: Magnetic displacement sensor
IPC: G01F23/70
Filed: 1973-04-03
Abstract: 1430307 Liquid level measurement REAKTIVA SZOVETKEZET 3 April 1973 15970/73 Heading H3H Liquid level is sensed by magnetically excited contacts arranged in the direction of level fluctuation in a system wherein the contact spacing is h times (h even) the unit of resolution (k) of the measurement, the magnetic exciting assembly can actuate (h/k) + 1 contacts at once and the contacts are electrically scanned, with h pulses being produced for each non-excited contact until an excited contact is reached and up to h - 1 more pulses are then generated depending on the number and position of further excited contacts. The system is scanned using an arrangement by which mn contacts are scanned using only m+n connecting wires. As described, h=4 and the contacts are reed switches arranged inside and against a D-shaped cross-section tube and the magnet assembly is attached to a float which surrounds the tube. The contacts are spaced by 4 cm (1 cm is the resolution) and the magnetic assembly comprises a 6 cm. magnet P 0  separated from a 2 cm. magnet P 1  by a 3 cm. non-magnetic member. For the system shown in Fig. 4, m = 4 and n = 3. Contacts 0, 16, 32 are wired together on the lefthand side and likewise 4, 20, 36; 8, 24, 40 and 12, 28, 44. On the other side contacts 0-12, 16-28 and 32-44 are connected together. The magnet assembly is constructed to represent each output level by a monophilic code which repeats and is moved one place to the right every h units and which is for this example 0=1000, 1=1010, 2=1110, 3=1100, 4=01000 &c. Push-button 1G actuates monostable MS which resets counters R, F and H having capacities h, m and n respectively and sets bi-stable BS which actuates clock AS. Clock pulses are fed via gate T to counter R and this counter generates an output pulse which is fed to counter F for every four (h) input pulses. Clock pulses are also fed directly via gate KA to a counter. Counter H is similarly stepped by output pulses from F occurring once every 4 (m) input pulses. The contents of counters F and H select the contacts via circuits M and I, respectively. When an actuated switch is reached (8 in Fig. 4) output circuit M switches gate T so that counter F receives clock pulses from AS and the next output pulse from R will reset the bi-stable B/S. It also closes gate KA to pulses from source AS. The circuit then reacts to the next three switches, corresponding to levels 12, 16 and 20 and which are, as shown, excited, non-excited, non-excited to supply one of 0-3 pulses to counter F depending on the switch states. Examples of monophilic codes for h= 2, 4, 6 and 8 and the method of calculating the magnet dimensions are described.
