Filed: 1924-08-27
Abstract: 221,213. British Thomson-Houston Co., Ltd., (Assignees of Eaton, J.). Aug. 27, 1923, [Convention date]. Protective arrangements; automatic circuitbreakers.-A protective arrangement for a motor or other device 12 comprises a thermal element 13, the heating coil 14 of which is connected in the motor circuit, and which upon overload bends to the right and allows a switch 10 to open; this in turn opens the motor circuit and as the element 13 cools its lower end bearing against the right side of a catch 19 on a member 15 rotates the member 15 into engagement with a contact 22 thereby closing the circuit to an electromagnet 16 which attracts an armature 17 and brings all parts back to their original position. The member 15 is pivoted to the armature 17 and is biassed to the position shown by a spring. As an additional precaution an electromagnet 23 may be provided in the motor circuit, adapted on a large overload of short duration to attract an armature 24 on the member 15, thereby rotating the member 15 free from the element 13. The switch 10 opens and the apparatus is reset as before. Fig. 5 shows a modification in which the contact 22 is replaced by a member 25 adapted to be rotated step by step by a catch 26 on the member 15. After the circuit-breaker has opened and closed a certain number of times an insulating sector 28 prevents the member from completing the circuit of the electromagnet 16, and the circuit-breaker remains permanently open. Later on it may be reset by closure of a switch 29.

Title: Process for oxidising liquid hydrocarbons and their oxidation products
IPC: C07C51/487
Filed: 1920-07-09
Abstract: Fatty acids are obtained by oxidizing, by means of air or oxygen in the presence of a catalyst, liquid hydrocarbons such as mineral oils and similar natural or artificial raw materials, which have been previously freed from hydrocarbons which tend to form resinous and asphaltic bodies; this purification may be effected by means of fuming sulphuric acid.  It is preferred to use as parent materials oil containing at least 90 per cent of hydrocarbons of the methane series.  According to an example, a Galician spindle oil is purified by fuming sulphuric acid, and is then oxidized by adding zinc stearate and blowing in oxygen at 110 DEG  C.  The reaction products are suitably worked up and may be converted into soaps.

Abstract: 670,573. Magnetic recording and reproducing apparatus. BRUSH DEVELOPMENT CO. July 28, 1947. [Aug. 2, 1946] No. 20296/47. Class 40 (ii). A transducer head for magnetic recording and reproducing comprises a magnetic core formed of two similar opposed strips 150 with width transverse to the plane of the core. The strips are mounted on a supporting member having outwardly projecting supports 165 receiving the pole tip regions of the core, transducer windings 151 and members 159 holding the core against the supports. The members 159 are tapered so that leaf springs 158 bearing on the cores press them into close relation with the members 159. Side walls 157 of the head form a magnetic tape guide. A cover completes the assembly. The hole faces of the strips may be polished and abut so that the non-magnetic gap measures fifteen microns or less. In Fig. 8, the pole pieces are spot welded or soldered together by short non- magnetic metal straps 390 and enclose a central structure 559 in two parts separated by metal spacers 563 secured together centrally and to the two parts but with free circular end gaps so that inserts expand the parts into close engagement with the surrounding pole pieces. Alternatively, the central spacers may be omitted and spacers inserted between the outer edges of the central support and the pole pieces, or the straps 390 may be omitted and the core strips cemented together. The magnetic record track may be mounted in or on a backing of resilient material or may be guided during operation between deformable resilient material and the transducer head, and may be in tape or disc form, in the latter case the head being pressed against and caused to traverse over the disc. The Specification, as open to inspection under Sect. 91, describes also, Figs. 5-9 (Cancelled) (not shown), a transducer core consisting of two flat abutting strips 250 mounted between the slotted periphery of a central support 259 and externally grooved projections 277, on opposite plates enclosing the core, which fit over the pole faces. The externally grooved projections and continuation grooves in the side walls of the plates form guides for a wire record. The exposed pole tips may also be grooved. This subject-matter does not appear in the Specification as accepted.

Abstract: 1350725 Electric battery CONSIGLIO NAZIONALE DELLE RICERCHE 4 May 1972 [31 Aug 1971] 20779/72 Heading HlB An electric battery includes a plurality of cells arranged in series, each cell comprising a bipolar electrode serving to separate neighbouring cells and an aqueous electrolyte of zinc bromide which is continuously circulated through the cells during the charging and discharging processes and stored in an autonomous tank when the battery is not in use; the bipolar electrode having deposited on one side a zinc anode and on the other a bromine cathode including an active cathodic mass, the mass containing an active cathodic substance which is insoluble in water and is capable of combining with cathodic bromine to form solid addition products, the substance being selected from alkylammonium perchlorates, diamine bromides or perchlorates, triamine bromides or perchlorates, additive substances being dissolved in the electrolyte to reduce the solubility of the active cathodic substance, to increase the conductivity and the acidity of the electrolyte and to encourage the zinc to deposit in a thin uniform layer. The bipolar electrode in one embodiment, Fig. 3, comprises a metal sheet 6 having a zinc layer 4 on one side and on the other side a plurality of graphite sticks 7 glued by graphite cement 2, with the channels 8 filled with a mixture of graphite, active cathodic substance and powdered porous carbon, surrounded by a retaining ring 5, and closed off by a porous insulating sheet 9. In another embodiment, (Fig. 2, not shown) the zinc layer 4 is located directly on an impermeable sheet of graphite fibres (1) and the sticks and the filling mixture are replaced by a graphite felt (3) impregnated with the active cathodic substance by an exchange process. Alternatively an impermeable moulded graphite sheet (4, Fig. 1, not shown) may be used in place of sheet 6 and have the filling mixture located between ribs moulded into the sheet. The electrolyte preferably comprises an aqueous solution of zinc bromide, hydrobromic acid, sodium sulphate and sodium perchlorate. The sulphate serves to maintain the conductivity of the electrolyte and to prevent free bromine dissolving in water. The perchlorate also serves to maintain conductivity and to reduce solubility of the solid addition products. The active cathodic substance may be tetra methyl, ethyl or butyl ammonium perchlorate, phenyl or cetyl trimethylammonium perchlorate and/or bromide or penta, hexa or deca-methonium perchlorate and/or bromide. The battery structure in one embodiment has a pump 20 to draw electrolyte from the tank 19 and feed it to the cells 15 through filters 21. Alternatively the filters could be placed in the pipes 23. Bubbles of gas are collected by pipes 28 and removed by pump 26. In another embodiment (Fig. 6, not shown) a pump (29) alternately sucks and pushes electrolyte from a tank (19) into and out of the cells and overflow tank 32 being provided for the pipes 23 with a conduit 33 connecting the tank to the pump.

Title: Rotary selector device
IPC: F16H61/26
Filed: 1974-05-10
Abstract: 1410460 Change-speed control ROBERT BOSCH GmbH 10 May 1974 [14 May 1973] 20796/74 Heading F2D Sliding of a pair of gears 12, 13 along a shaft 10 to select either of two speeds in, e.g. a boring machine is effected by a rotary selector comprising a pin 35 projecting from a disc 16 which has a two-lobed undulating, e.g. sinusoidal, surface coacting with a similarly shaped surface of a fixed disc 17, the latter being bored to receive a shaft (not shown) by which the disc 16 may be rotated through 180 degrees by a selector knob 31 from a first position, shown, through neutral, to a second position. In both the first and second positions of the disc 16 the axis of the pin 35 intersects that of the shaft 10. Due to the undulating surfaces of the discs, the disc 16 and the knob 31 are necessarily displaced axially during their rotation and are biased outwardly by an internal compression spring between the disc 17 and the knob 31. If, whilst the gear pair is at either of its extreme positions, the knob is struck so that it is moved inwardly, the rounded or pointed end of the pin 35 coming into contact with a collar 11 between the gears rotates the disc 16 to place the mechanism in neutral. A small flat or indent may be formed on the two high points of the undulating surface of the member 17 so that the mechanism may remain in neutral.
