Title: Improved manufacture of leather from shark and the like fish skins
IPC: C14C1/00
Filed: 1923-12-18
Abstract: 228,310. Ehrenreich, A., and Bendixen, K. Dec. 18, 1923. Treatment preliminary to tanning.-In the manufacture of leather from skins of sharks and like fish, the dermal armour is loosened by a chemical treatment and is then removed by a gentle mechanical treatment. The armour may be removed either before or after tanning. In the former case, the skin is treated with an aqueous solution of a weak acid, preferably organic, e.g. formic acid, until the armour is loosened, when the skin is milled or scrubbed to remove the armour, and tanned by any suitable tanning agents. In the latter case, the skin is tanned with vegetable or organic tanning agents and is then treated with an aqueous solution of a stronger acid, e.g. hydrochloric acid, until the armour is sufficiently loosened to be removed by milling.

Filed: 1975-07-17
Abstract: 1492803 Detecting cancer H W SIMPSON and D GREEN 17 July 1975 [19 July 1974] 32041/74 Heading GlN (E) In a garment, e.g. a brassiere 10 for detecting cancerous tumours which are generally hotter than the surrounding flesh, a number of temperature sensors 11 are strategically placed in the garment. The sensor 11 outputs are monitored and stored at predetermined intervals. The associated electronics which is in miniaturized form, is also contained within the garment. Each temperature sensor 11, which may comprise a silicon transistor mounted on an alumina ceramic base, is connected to an analogue multiplexer circuit 12. On receipt of a strobe signal from a control circuit 13, the multi-plexer 12 scans the sensors 11 gating the signals to a sample and hold circuit 14. The sample and hold circuit signal is applied to an A/D converter 16 under the control of clockpulses from the control circuit 13. The A/D converter 16 outputs are fed to a buffer register 17 from where the signals are eventually transferred to a storage register 18 of much larger capacity. A clock 19 supplies pulses to the control circuit 13 and determines when the sensors 11 are scanned as a group (e.g. every 30 minutes). After the garment has been worn for several days, it is removed and plugged into a data logging apparatus 22 by means of a socket 23 and a plug 24. The data output may be numerical, or on a tape, or in chart form. A more detailed form of the electronic circuit Fig. 3 (not shown) is described.

Title: A process and apparatus for the ventilation and division of the air space in an enclosure
IPC: F24F9/00
Filed: 1936-11-24
Abstract: 481,991. Ventilating systems and apparatus. POLO, L. Nov. 24, 1936, No. 32126. Convention date, Nov. 25, 1935. [Class 137] The air space in an enclosure is divided and ventilated by providing an air curtain which is established by introducing air under pressure at one edge of the curtain, and evacuating the air by reduction of pressure at the opposite edge of the curtain., In Fig. 2 is shown an opening between two rooms, air being forced through apertures such as 8 in duct 9, and withdrawn by similar apertures in duct 10, an air curtain 11 being formed which entrains some of the air from each room, and thus assists ventilation. An air curtain may be formed around a bed by supplying the air under pressure from a conduit 22, Fig. 4, and abstracting it through a perforated conduit 20 around the bed, which is not shown, the air curtain 23 isolating the atmosphere immediately adjacent the bed from that in the room, thus serving, if required, as a mosquito curtain. The air may be mixed with disinfectants, or ozonized before use. A passage, for example, into a shop from the street has perforated pressure and vacuum ducts 24, 25 at each side, an air valve 27 controlled by an electromagnet 28 being energized when a person steps on a loose board so that the air valve is closed and the air current cut off when a person. passes between the ducts. The air may be conditioned before use, and mixed with smoke or colouring matter to give it opacity or colouration.

Title: Improvements in or relating to the manufacture of bent toughened glass
IPC: C03B27/00
Filed: 1948-12-13
Abstract: 660,824. Glass manufacture. PILKINGTON BROS., Ltd. Dec. 13, 1948 [Dec. 22, 1947], No. 32217/48. Class 56 Toughened glass is bent and de-toughened along a selected line by heating it along the line by high-frequency di-electric oscillations, thus producing a zone which permits bending in hinge-like manner. In Fig. 4, the glass plate 1 is supported on an inverted V-member 30, being positioned by a stop 33. Electrodes 36, 41 are arranged transversely below and above the glass, the electrode 41 being carried by but insulated from a frame 39 pivoted at 40 to the member 30. The electrode 36 is housed in a silica tube 34 which is joined to a vertical tube 35 enclosing the conductor 38. The member 30 is wheeled into, and through a furnace, and current is provided by conductor rails 46, 47 and brushes 37, 42. The rails are of such length that the glass is sufficiently softened, when the brushes leave the rails, to allow the glass to bend under its own weight. In a modification, the glass is conveyed through the furnace in a vertical hanging position. The electrodes are horizontal, and, when softening is complete, the electrodes are displaced laterally relatively to the glass, so that the part of the glass below the electrodes, in maintaining its vertical position, hinges about the softened zone. According to the Specification as open to inspection under Sect. 91 of the Acts, the glass, immediately after toughening, is heated by high-frequency oscillations in predetermined areas, the subsequent cooling of the glass being so regulated that the heated areas are detoughened. This subject-matter does not appear in the Specification as accepted.

The holes m<1>, m4 communicate by a slot m<5> and, when the adjustment is to be made, the sleeve m<2> is withdrawn against the action of the spring m<3> until the stud m is moved along the slot m<5> from one hole to the other. Gas, supplying by meter.-The ratchet-wheel n is connected to a wheel n<2>, Fig. 1, which rotates a wheel nut n<3> thereby moving a threaded spindle o to open the gas valve. The valve has an operating arm g engaged by a stud p<4> on a sleeve p that is held between collars p<1> on the spindle o and prevented from rotation by an arm p<2> engaging a slotted guide-way on the meter casing. The spindle o is rotated to close the valve by a worm wheel r splined thereto and driven from the usual index arbor s<1> of the meter either directly through a worm s, when a penny is used, or through reduction gearing v, u<2>, when a shilling is used. The worm wheel r is moved along the spindle o into or out of engagement with the worm s, as required, by a wheel w having a peripheral groove to engage the wheel r, the wheel w being keyed to a spindle x which is parallel to the spindle o and is held in adjusted position by grooves x<1>, x<2> thereon engaging a bearing y under the influence of a leaf spring x<3>. To enable the wheel r to be rotated slightly so that its teeth are presented in the proper position for ready engagement with either the worm s or the reduction gear, a loose ring of teeth w<1>, Fig. 15, is eccentrically mounted on the spindle x and frictionally held by a spring washer between the flanges of the wheel w. By rotation of the spindle x the wheel r is slightly rotated, its further rotation by the meter then causing the teeth w<1> to run out of gear. Mechanism as described in Specification 342,277 for preventing fraudulent actuation by " pumping " is provided.

IPC: G01L1/10
Filed: 1955-11-11
Abstract: 823,847. Electric indicators. FERRANTI Ltd. Dec. 11, 1956 [Nov. 11, 1955], No. 32256/55. Class 40 (1). A transducer which supplies an electric signal having a frequency proportional to an applied variable mechanical force comprises two flexible longitudinal conductors 11 and 12 of equal mass/unit length and each mounted so as to be placed in tension and be free to vibrate transversely, means to maintain the conductors in vibration, and means differentially adjusting the tension in the conductors in linear dependence on the applied force so as to differentially vary their frequencies of vibration the difference between which is obtained as a measure of the applied force. The conductors are thin strips of beryllium copper fixed at one end to a base and connected by a cross-head 13 at the other end so as to lie parallel to one another. The cross-head 13 is balanced on a fulcrum 14 of a lever 15 which by spring 17 holds the conductors 11 and 12 in tension equally. An arm 19 extending from the cross-head enables a force F applied to it to increase the tension in one conductor while decreasing the tension in the other conductor, thereby differentially varying the natural frequency of vibration of the conductors. A magnetic field is applied transversely to the conductors over the dotted area and the intensity of the field along the length of the conductors preferably has a sinusoidal variation. Each conductor is connected in the input stage of a valve circuit 21, or 22, with positive feed-back to maintain vibration of the conductors at their natural frequencies. The frequency of oscillation of each valve circuit 21 and 22 is the frequency of vibration of its associated conductor and is fed to a mixing stage 23 which extracts their difference. To measure this difference, which is indicative of the applied force, the number of cycles in a predetermined interval may be counted.
