Title: Improvements in or relating to kinematographic apparatus with provision for recording and reproducing sound
IPC: G03B31/00
Filed: 1930-10-22
Abstract: 366,083. Sound recording or reproducing means associated with kinematographs. HARRISON, C. A. H., Grand Buildings, Trafalgar Square, London. Oct. 22, 1930, No. 31788. [Class 40 (ii).] A combined sound and picture film record has the pictures compressed in one direction on a fi 1 m of standard width so that the area of film available for sound records is increased in order that two separate sound records can be accommodated. As shown in Fig. 1, a film 10 on which a compressed picture record has already been recorded is moved past two similar sets of optical soundrecording apparatus each comprising a light source 17, light from which is modulated by a sound-influenced light-valve such as 15 and projected by lenses 11, 13 on to one margin of the film 10. The light valve 15 may be fed with signals from a microphone which picks up the voices of the actors while the light-valve 16 of the other recording system is influenced from a microphone which receives other sounds such as music. The two sound records may be registered one on each side of the pictures or they may be adjacent to each other on the same side of the pictures. These sound records are reproduced by apparatus as shown in Fig. 2, comprising light sources 23, 24 which project light through suitable optical systems and the respective records to photo-electric cells 21, 22, respectively. The signals from each sound record can be supplied to a separate loud-speaker. As illustrated by Fig. 3, the records of speech are reproduced by a loudspeaker 35 disposed behind the screen 36 while the music is reproduced by a loudspeaker 37 situated in the orchestra well. Specifications 335,864, [Class 97 (i), Optical systems &c.], and 351,927 are referred to.

Title: Improvements in or relating to electric resistance furnaces
IPC: H05B3/62
Filed: 1959-09-18
Abstract: 925,899. Electric furnace resistance elements. KANTHAL A.B. Sept. 18, 1959 [Sept. 22, 1958; Dec. 3, 1958; Feb. 6, 1959], No. 31918/59. Class 39 (3). An electric resistance furnace is heated by vertically disposed, hairpin-shaped resistor elements containing Si so that a superficial layer of SiO 2  is formed in operation, the temperature of operation being such that the superficial layer flows slowly downwards and leaves the heating elements as drops so that adherent impurities are removed. The heater elements are of MoSi 2 , made by powder metallurgy and having a ceramic binding agent of fusible clay e.g. bentonite with residues of carbides, oxides, borides and other metals converted to oxides in operation which flow together with the SiO 2 , or of silicon carbide. The Mo may be replaced by one or more of Ti, Zr, Hf, V, Nb, Ta, Cr or W and the processing is of steel ingots or of glass, ceramics or chemicals. The invention can be applied to soaking pit furnaces continuous heating furnaces, open hearth furnaces, rotary hearth furnaces and high-temperature furnaces. In one form (soaking pit furnace), Fig. 1, there are two juxtaposed rows of heating pits each row containing e.g. 10 pits. The covers 21 can be lifted and moved aside by a traverse. The heaters 26 instead of hairpins may have tubular lead in and glow portions and a rod or tubular return insulated from each other by an intermediate oxide layer. Vertical webs are placed between the glow zones of the elements. The heating elements are connected in groups each comprising four juxtaposed heating pits each group being controlled separately. Steps 29 have slag-receiving pockets and are associated with slag-removing openings in the furnace walls. In Figs. 4-6 (not shown) the heater elements are bent at 120 degrees, bent perpendicularly or arched or may depend vertically for their entire length, Fig. 7 (not shown). The rotary hearth of a rotary hearth furnace may be moved continuously or stepwise, Fig. 16 (not shown). In a high-temperature furnace, Fig. 19, rollers 94, 96 are grooved so can carry one, three, or any number of elongated rod shaped or tubular bodies the shafts 95, 97 of which are driven together or separately; they may have a central channel for water cooling. Ribs 101 protect the heaters 99 from damage. Specification 925,898 is referred to.

IPC: A61H1/02
Filed: 1955-11-08
Abstract: 790,152. Orthopaedic traction apparatus. GRAFTON ACCESSORIES, Ltd., and RENN, F. W. Nov. 2, 1956 [Nov. 8, 1955], No. 31937/55. Class 81 (2). Orthopµdic traction apparatus comprises a movably mounted element, for applying a tractive force, connected to a member oscillatable about a displaceable pivot and reciprocatory drive means, the arrangement being such that displacement of the pivot in one direction independently of the reciprocatory drive means applies a sustained tractive force and oscillation of the member by the reciprocatory drive means applies a reciprocatory tractive force. A patient is supported on a table comprising a framework 1 carrying fixed upholstered sections 3, 4 and an upholstered foot section 2 which is slidable on rails 6 forming part of the framework 1. A spring 16 urges the foot section 2 towards the head end of the table, a buffer 18 limiting movement in this direction. A pair of parallel links 34 on a pivot 33 carried by a support 24 slidable on a rail 21 are connected through a dash-pot 40 to a lug 15, fixed to the foot section 2. A threaded spindle 28 engages a threaded hole in a lug 27 of the support 24 and is rotatable by a handle 32 to displace the support 24 and the pivot 33 in the direction of the longitudinal axis of the table. The links 34 are also connected to a rod 37 which may be reciprocated by an electric motor 38. In use the upper part of the patient is connected by a harness with a spring balance 8 attached to the table and the lower part of his body is secured by a harness to a post 7 fixed to the slidable foot section 2. Rotation of the spindle 28 and consequent movement of the pivot 33 causes compression of a spring 43 of the dashpot 40 which is followed by movement of the foot section 2 relative to the fixed table sections 3, 4 so that a sustained traction can be applied to the patient. Reciprocation of the lever 37 by the electric motor 38 causes the links 34 to oscillate so that the foot section 2 reciprocates to apply an intermittent traction to the patient. Similar mechanism may be provided in a cabinet which is attached to a table, a reciprocatable rod projecting from the cabinet being secured either to a sliding table section or to a harness strapped to the patient.

Title: Improvements in and relating to electromagnetic adjustable drives
IPC: F16H27/10
Filed: 1952-12-17
Abstract: 730,677. Variable-speed gear; controlling clutches. AUTOMATA. Dec. 17, 1952 [Dec. 17, 1951], No. 31962/52. Class 80 (2). An electromagnetic adjustable drive comprises an electromagnetic friction clutch with one or two stationary windings, and an impulse transmitter which switches the magnet winding or windings alternatively on and off, and is characterized by the provision of means for varying at will the ratio between the duration of the current impulses and the duration of the intervals between them. The velocity ratio of the drive transmitted by the clutch is thus varied between the limits of direct drive, when the current flows continuously, and neutral, when no current impulses are supplied. The impulse transmitter may be a thermionic oscillator, the switching impulses of which can be adjusted by changes of electrical factors, or it may be a mechanical device. In one mechanical form a cylinder 9, Fig. 2, of insulating material has insets 10 of conducting material such as brass &c. engaged by a brush 11, slidable axially of the cylinder on rotation of a handwheel 5, the insets being electrically connected and the brush 11 &c. connected into the feed circuit of the electromagnetic clutch; the cylinder is rotated by a mechanical connection to the driving part of the clutch. In another form of impulse transmitter, Figs. 5, 6 (not shown), radial insets of conducting material on the surface of a disc of insulating material are engaged by a brush manually adjustable over a radius fixed relatively to the disc. As applied to reversing variable-ratio gearing, a motor 16 rotates bevel gears 18, 19 in opposite directions and either of two stationary windings 22, 23 are fed with impulses of current, according to the setting of a switch 31, to attract either of two discs 24, 25 into engagement with friction facings 20, 21 on the bevel gears, the impulses of current being fed in through the brush 11 and cylinder 9, slip ring 33 and brush 34; the cylinder 9 is rotated by a chain connection 30 with a shaft 29 itself rotated by a belt drive 26, 27, 28 from the driving shaft of the motor 16. As combined with a two-speed change-speed gear, the motor 16 drives a gear 36, Fig. 4, fast on a bush 38 freely rotatable on an axially slidable shaft 39 to which is secured a clutch disc 40 engageable with a friction lining 37 on the gear 36, the shaft also carrying an armature disc 42 for attraction by a stationary coil 41 when current is fed thereto, to move the shaft axially and engage the clutch; the impulse transmitter is rotated by a chain 45 passing over a sprocket 44 connected to the bush 38 and gear 36. The shaft 39 carries a pinion 50 giving a reduced drive through a train 51 ... 54 to a driven shaft 48, upward movement of a lever 49 from the position shown sliding gears 50, 51 and 53, 54 out of engagement and simultaneously engaging a positive clutch 55 for direct drive.

Abstract: 859,578. Waveguide non-reciprocal devices. COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. Oct. 10, 1958 [Oct. 29, 1957], No. 32480/58. Class 40(8). [Also in Group XXXV] The gyromagnetic resonance frequency of a non- reciprocal microwave transmission device is rendered independent of ambient temperature by shunting part of the polarizing magnetic field around the ferrite element. The invention may be applied to a resonance isolator having ferrite elements 2, 3 arranged in a waveguide 1. Part of the field of the polarizing magnet 4 is shunted around the outside of the waveguide by shunt elements 5, 6. These are made of a material, e.g. a ferrite composition, having a magnetic induction which decreases more rapidly with temperature than the induction in the magnet 4. It is thus possible to obtain a field across the gap of the magnet which does not vary with temperature or which increases with temperature.

[Class 8 (ii).] Solid. carbon dioxide is vaporized, freed :from air and conducted to an apparatus for carbonating liquids. Fig. 1 shows apparatus wherein a block of solid carbon dioxide is placed in a chamber A on a partition, 1 and the cover then closed and sealed, the substance is allowed to vaporize and air in the chamber blown off by a relief valve 7. The valve is then closed and the sliding partition 1 withdrawn, allowing the block to fall on to a grid 13 in the lower part of the chamber. Heating medium is passed through a coil 17 in the chamber and the gas evolved passes through a warming chamber 9 to a gas-holder 10. The rise of this holder to a certain height causes a stop 20 to close the valve 18 controlling the supply of heating medium. Water from the block drains away through a cock 14. The chamber A may alternatively be heated by electricity or gas burners or by adjunction of articles &c. to be cooled, e.g. the chamber may be surrounded by a chamber in which ice cream mav be frozen or meat cooled. The warming chamber 9 may also be a refrigerating chamber fitted with a gas-tight door. The valve 18 or a rheostat may be controlled by the pressure of gas in the chamber A. In a modification, the partition 1 may be vertical, the block being pushed from one compartment to the other by a rod manipulated from outside. The warming chamber 9 and holder 10 may be dispensed with. The chamber A may comprise one compartment only fitted with a relief valve. Fig. 3 shows a vaporizing chamber 26 in which the block may be pushed by a piston 34 into the bell of the gas-holder wherein it rests on a grid 35. The water in this holder may be heated, the temperature being controlled by a thermostat.
