Title: Improvements in or relating to bakery conveyor systems
IPC: A21B3/07
Filed: 1955-11-09
Abstract: 819,285. Conveyers. VICARS Ltd. T., & T. (Petersen Oven Co.). Nov. 9, 1955, No. 31984/55. Class 78 (1). A conveyer system for feeding loaves of bread to a slicer-wrapping machine includes a unit comprising two or more narrow, parallel belts spaced apart a distance greater than the width of the loaves and/or spaced from the sides of the unit by such distance, so that loaves of bread fed to the unit in a generally endwise direction are caused to fall between the belts and/or between one of the belts and the adjacent side of the unit, whereby only transversely disposed loaves are carried by the belts. As shown, two narrow belts 107 are disposed such as to leave a gap between the belts, and a further gap between each belt and the adjacent side of the unit, each gap being greater than the width of a loaf. Loaves are fed to the belts 107 from a preceding arcuate endless conveyer 23a, being guided towards the centre of the unit comprising the belts 107 by guides 102, 103. Loaves orientated substantially longitudinally of the belts 107 fall between them or between one of the belts and the side of the unit and pass down a shoot 108 on to a conveyer belt 40 for re-circulation. Loaves orientated substantially transversely of the belts 107 pass on to a belt conveyer 101 which feeds a slicerwrapping machine. A pivoted deflector 114 is mounted for swinging movement across the conveyer 101, the deflector being swung from an inoperative position at the side of the conveyer 101 into a deflecting position by a fluidpressure cylinder 117 controlled by the slicerwrapping machine so that when the machine is full or jammed the loaves are deflected by the deflector 114 into an arcuate shoot 120 leading to the belt 40.

Title: Improvements in circuit arrangements for compensating for potential fluctuations
IPC: G01R23/00
Filed: 1945-12-06
Abstract: 609,226. Automatic regulation. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN. Dec. 6,1945, No. 33020. Convention date, Sept. 17, 1940. [Class 38 (iv)] A load comprising two or more discharge tubes is divided into two groups, one of which is dependent, in regard to their common function, upon the other and one group is supplied with an unstabilized direct voltage while the other is supplied through a Wheatstone bridge with a voltage over-compensated in respect of fluctuation in the said direct voltage. In the Figure, T represents a lowfrequency oscillator of the beat-frequency type, of which one oscillator is supplied at terminals 3, 4 from a D.C. supply E which may fluctuate and the other at terminals 5, 6 with the overcompensated voltage to produce at terminals 7, 8 an output independent of fluctuations of the supply E. To obtain partial, complete or over-compensation of any D.C. voltage, a Wheatstone bridge is arranged to contain a pair of adjacent arms, to which one terminal of the fluctuating voltage is applied, containing impedances such as L, R2, each having a different ratio of differential resistance (dV/dI) to static resistance (V/I). Thus, one may be a flow discharge tube and the other a resistance. The bridge may be completed by resistance, e.g. the resistance R1 and the resistance of the load across terminals 3, 4. The stabilized or over (or under) compensated voltage is the difference between the voltages across L and R2.

Filed: 1955-11-15
Abstract: 836,703. Automatic circuit - breakers. ENGLISH ELECTRIC CO. Ltd. Nov. 9, 1956 [Nov. 15, 1955], No. 32623/55. Class 38 (5). An electromagnetically-operated circuitbreaker has a longitudinally-movable actuating shaft with a magnetic-coupling to an operating armature within a dust-proof enclosure. The breaker contacts 12 (shown closed) are coupled to a connector 11 attached to the actuating-shaft 15 which is biased to the open position by a spring 35 acting on a piston 34 attached to the shaft 15 and having its movement limited by resilient washer 44 engaging projections 34a. Two armatures 27 attached to a common mounting which is pivoted on the shaft 15 form a magnetic coupling with an E-shaped holding magnet, the cores 25, 28 of which are attached to a shaft 16 carrying an armature 17 for attraction by the closing electromagnet formed by parts 18, 19 and coil 23. The core 25 is surrounded by a coil 26 and is divided on the centre line so that parts 25, 27, 28, and 29 form a magnetic circuit on each side of the centre line. After the coil 26 has been energized to effect coupling of shafts 15 and 16 the coil 23 can be energized to attract the armature 17 and close the breaker which will be held closed, when the coil 23 is de--energized by a gravity latch 32 engaging the core 28. Tripping may be effected by de-energizing the coil 26 or by an opposing flux produced by a coil 31 and in either case the armatures 27 are released and the spring 35 opens the breaker. During its upward movement one armature 27 engages a projection 32a on the latch 32 to release the core assembly which is moved upward by a spring 24. The coil 31 may form an equivalent figure-of-eight or two parallel loops about the outer cores after passing through the divided centre core, the outer turn or turns including a calibrating bar 36 which can be moved to set the tripping current. A handle 41 enables the breaker to be hand closed after energizing the coil 26.

IPC: C03B35/18
Filed: 1968-07-09
Abstract: 1,249,672. Etching. GLAVERBEL 9 July, 1968 [12 July, 1967], No. 32644/68. Heading B6J. [Also in Divisions B2, B8, C1 and F2] A sheet 43 Fig. 6 is supported by conveyor rollers 25 between which are positioned, out of contact with sheet 43, hollow rollers 26 formed with radial orifices 29 which may be in the form of projecting nozzles and which may be arranged helically on the surface of the rollers. Pressurized coating or etching fluid is supplied to the interior of rollers 26 and is discharged, as the rollers rotate, on to the surface of sheet 43. The hollow rollers may alternatively be arranged above the sheet, or hollow rollers may be arranged above and below the sheet. When conveyer rollers are used in contact with the sheet, the latter may either be driven or transport of the sheet is effected by fluid discharged from the hollow rollers. When heated sheets, e.g. of glass, are transported by contact with conveyer rollers, the latter may be covered by a material e.g. boron nitride, which does not stick to the glass at these elevated temperatures. In Fig. 9 a duct 1 has a curved upper surface formed with spaced transverse slots 4 and engaged by the upper run of an endless belt 2 supported by driven rollers 3 and formed with aperture 5. Compressed fluid is thereby discharged from duct 1 through the slots 4 and the apertures 5 which thus direct streams on to a sheet 6, the aperture 5 approaching and receding from sheet 6. In Fig. 11 a curved sheet of glass 102 is engaged between upper concave rollers 104 and lower convex rollers 101 either or both of which may be hollow and apertured. Sheet 102 is engaged between the co-operating rollers 101, 104 on its upper surface by concave rollers 107 and on its lower surface by supporting convex roller 105. The apparatus may be used for depositing optical layers on glass, the enamelling of sheet metal and glass, and the etching and silvering of glass. As an example, a sheet of glass, supported vertically, passes between rollers supplied with a 50% solution of industrial hydrofluoric acid for etching through or frosting the glass.
