Title: Improvements in or relating to sorting, marking or otherwise dealing with characteristics of workpieces
IPC: A43D1/08
Filed: 1924-04-01
Abstract: 235,670. British United Shoe Machinery Co., Ltd., Tinkham, D. W., and Heather, C. H. April 1, 1924. Splitting-apparatus.-In machines for grading workpieces, for example machines for grading and evening soles and heel lifts for boots, means are provided for varying the grading steps either regularly or irregularly throughout part or the whole of the grading range. As applied to the grading and evening machine described in Specification 17808/09, the ratchet-wheel 135 by which the mechanism is locked when the workpiece has passed the gauging rollers, is fitted on its edge with an adjustable plate 2 which prevents the locking pawl 131 from engaging the teeth corresponding to the grades not required to be distinguished. By moving the pawl 131 laterally it may be set to engage all of the teeth and so effect regular grading. A spring-pressed snap bolt 6 is provided. Alternative grading by different steps may be obtained by providing two wheels 135 with differently spaced teeth, the pawl 131 being movable from one to the other. If permanent irregular grading is desired, selected teeth may be removed from the wheel. Fig. 4 shows an arrangement in which the setting wedges 67 for the upper roller 70 of the evening apparatus described in Specification 17808/09, co-operate with adjustable lower wedges so that the grading may be effected by the usual " half-iron " steps, or by full " iron " steps as desired. The lower wedges are each formed of two differently stepped parts, one of which may be moved by a handle 19. Specification 176,895 also is referred to.

[Class 106 (ii)] A pneumatic plug gauge comprises a cylindrical hard metal body 1 having an air conduit 2 leading to radial housing 4 accommodating soft metal tubular supports 5 in which are fitted hard metal nozzles 6 slightly sunk relative to the outer wall of the body. The gauge is made by fitting the nozzles in the ends of the tubes 5, fitting the tubes in the housings 4, machining the nozzles and body 1 simultaneously so that their outer walls are flush, and subsequently driving in the nozzles all to the same degree. In the gauge shown, two nozzles 6 are provided and air supplied via a handle 3 to the conduit 2 is evacuated from the nozzle outlets via conduits 8, 9. The coefficient of expansion of the tubes 5 may be similar to that of the piece to be measured to eliminate errors due to temperature. Fig. 3 shows a nozzle-adjusting machine comprising an adjustable sleeve 18 projecting from a V-groove 15 in which the gauge is located, and a slidable piece 22 which is actuated by a screw-threaded plug 27 to drive in a nozzle. The displacement of the piece 22 is measured by apparatus 32. The gauge is then turned upside down and the operation repeated on the other nozzle.

Abstract: 943,610. Dental engines. DENTALWERK BURMOOS G.m.b.H. March 8, 1961 [March 9, 1960], No. 8459/61. Heading A5R. [Also in Division B3] A collet, primarily for use in the chuck of a turbine type dental drill, comprises a tubular sleeve 1, of resilient material, having longitudinal slots 3 extending inwards from one end and with the resultant tongues 12 bent outwardly at a point approximately half way along their length. When these tongues are compressed radially and the collet is inserted into the driving sleeve 8, until a collar 5 bears against the end of the sleeve, the central portions of the tongues become bowed inwardly so as to be capable of gripping a tool shank inserted in the collet while exerting an outward pressure on the sleeve 8 to obtain the necessary frictional drive. A divided collar 4, at the open end of the collet, prevents its accidental withdrawal from the driving sleeve. In a modified collet for use in single-ended driving sleeves, it is retained by projections on the outer side of the resilient tongues engaging in an annular recess in the sleeve.

Abstract: 483,880. Cores for expansion joints in cast concrete surfaces. MOLL, H. March 23, 1937, Nos. 8545 and 8546. Convention dates, March 23, 1936 and Dec. 12, 1936. [Class 20 (ii)] A core for use in forming the expansion spaces between large concrete masses, cast in situ, in the construction of floors, pavings or roads, is formed in two or more parts, relatively adjustable vertically in order that the upper edges of the concrete sections may be adequately supported during the finishing operations. The upper core member is formed of two side plates 51 connected by bolts 6 in staggered formation which may be surrounded by sleeve distancepieces, and is supported on the upper surface of a lower core member 4 during the formation of the upper concrete layer 2 on the already prepared foundation 3 and lower layer 1. After the casting of the upper layer, the upper core member is raised by wedge tools 9, Fig. 3, and supported by wedges 10 bearing against the lower pins 6 of the upper core and the upper edge of the lower core, and so that its upper edge projects above the concrete surface while its lower portion maintains contact with the lower core member. A finishing tool 11 may then be slid along the upper core member as guide. Theside plates of the upper core member may diverge slightly towards the top of the core. In a modification, Fig. 4, a third adjustable hollow core 13 is superposed on the core member 5<1> which is supported by a hollow lower core member 4, adjustment for height occurring between the core members 13 and 5<1>, and all the core members being removable after the concrete surface has hardened. In a further modification, Fig. 7, the upper core member is formed of divergent side plates 5<1> connected by means of resilient straps 14 of U-formation with the lateral sides opposite to or displaced longitudinally of each other, the plates being maintained in spaced relationship by plugs 15. The upper portion of the adjustable core member may be bulged to form a large recess.

Title: Improvements in electric motors, particularly applicable to toys
IPC: H02K25/00
Filed: 1959-03-12
Abstract: 858,160. Toy vehicles ; magnetic toys. LIBRAIRIE HACHETTE. March 12, 1959 [March 13, 1958], No. 8667/59. Class 132(3). [Also in Group XXXV] In an electric motor for a toy motor car moving on conductor rails 16, 17, the rotor comprises wheels 2, 3, on axle 8, of soft iron discs 4 having slots 5 filled with insulating material and poles 6, each wheel being secured to an iron half-core 9 to form a half-rotor, both halves being fitted into solenoid 10 wound on former 11. The stator comprises three soft iron bars 13 and permanent bar magnet 14, transversely mounted in plastic body 1, the bars being so placed radially that when slots 5 are opposite bars 13 a pole is opposite bar 14. Each pole has a spur 7 in the direction of rotation. Solenoid 10 is so wound that wheel 2 forms a north pole adjacent that of bar 14 and wheel 3 forms a south pole. Bar 14 thus repels poles 6 adjacent to its ends to turn the rotor, while, due to spur 7, the poles are attracted by bars 13 in the direction of rotation. When a slot 5 is in contact with rails 16, 17, and no current flows, bar 14 attracts the pole adjacent to its ends and a new pole is brought into contact with the rails.

Title: Improvements relating to rotary engines
IPC: F01C3/08
Filed: 1959-07-12
Abstract: 889,246. Rotary internal-combustion engines. HARDY, C. C. M. Oct. 12, 1960 [July 12, 1959], No. 8676/59. Class 110 (2). A rotary I.C. engine including a compressor, combustion chamber, and a turbine, comprises a compressor A having a pair of intermeshing screw-like conical rotors 1, 2 positioned in a conical casing 3, to define a plurality of pockets 17 of decreasing volume from the air intake end 9 to the compression chamber 19 and a turbine B having a pair of similar rotors 4, 5 defining with a conical casing 6 a plurality of pockets 18 of increasing volume from the combustion chamber to the outlet 10. Fuel injected into the combustion chamber 19 through injectors 20 mixes with the compressed air and the mixture ignited either by ignition means or by cornpression ignition rapidly expands to rotate the turbine which through a shaft 11 drives the compressor and a power take-off (not shown) to do useful work. A seal may be provided between the casings and the peripheries of the rotors by actual contact, by spring-loaded sealing strips located in rotor grooves or by roughening the peripheral surfaces of the rotors to cause a turbulent boundary layer of air or gas. With the latter method, since there is no mechanical friction between relatively moving parts, the engine can move at high speeds without danger of seizure, overheating or wear and lubrication between the parts is then unnecessary. Moreover manufacturing tolerances may be greater so that the casings and rotors may be manufactured from centrifugal castings or by means of mould powder metallurgy. Also, non- metallic materials such as ceramics or porous or semi-porous refractory materials may be used for these parts. The rotors may be axially adjustable by means of a differential screw and a centrally splined portion of the shaft 11. The casings may have water-cooled passages 21. Alternatively to provide gradually decreasing volume pockets 17 and gradually increasing volume pockets 18, the rotor shafts may be parallel and the pitch of the rotors varied along the lengths of the shafts, or the shafts may be parallel and tapered. A modified construction includes three intermeshing rotors both for the compressor and the turbine.

Abstract: 960,735. Determining liquid leveL D. E. ATKINSON. March 6,1962 [March 23,1961], No. 8682/62. Heading G1N. [Also. in Division G3] A material level indicating device comprises an oscillating circuit which includes a resonant circuit formed solely by a section of high frequency transmission line, disposed to detect the material whose level is to be indicated, the oscillating circuit ceasing oscillation when the material level reaches a predetermined value. As shown Fig. 1, a container 11 has a filler opening 13 and a dispenser opening 15 provided with a gate 17. A level detector 19 controls the operation of a filling device not shown, so as to maintain the contents at a level 23 by providing an output signal when the level falls to a level 23<1>. The electronic circuit, Fig. 3, is arranged as an Hartley oscillator the resonant circuit of which is formed by a section of a coaxial transmission line shorted at one end and having an outer conductor 37 approximately one-half wavelength of the desired oscillation frequency and an inner conductor 38 of three quarters of a wavelength which acts as an antenna. One end of the line is shorted by a plate 41 and the space between the inner and outer conductors is sealed by an insulating material. The detector assembly is contained within a protective iron pipe 45. A valve 25 is connected as shown to the section of transmission line and since the oscillator operates in class C the cessation of oscillation when the material contacts the antenna causes a rise in anode current which operates a relay 35, contacts 47 of which control the filling device 21. In modifications, the coaxial transmission line, closed at one end, is replaced by (a) a parallel wire transmission line or (b) a coaxial transmission line closed at both ends to form a coaxial resonant cavity. In further modifications, Figs. 6, 7 and 8, not shown, the Hartley oscillator is replaced by a tuned-plate-tuned cathode oscillator where both plate and cathode resonant circuit are formed by sections of transmission lines so as to improve stability with change in ambient temperature.
