Title: Improvements in or relating to candy cleaning machines
IPC: A23G7/00
Filed: 1950-09-18
Abstract: 672,589. Cleaning moulded confectionery. CURRIE MANUFACTURING CO: Sept. 18, 1950 [Nov. 5. 1949], No. 22890/50. Class 87 (ii) A candy-cleaning machine, the purpose of which is to clean powdered starch off sweets which have been moulded in starch moulds, comprises a drum 10, a substantially cylindrical brush assembly rotatably mounted in the drum and having cleaning brushes 12 with bristles directed radially inward of said assembly, a rotatably mounted inner cleaning brush 11 extending through the assembly with its bristles opposed to those of the brushes of said assembly, the brush assembly and the inner brush being so arranged as to provide a channel for axial movement of the sweets therebetween, and means for driving the brush assembly and the inner brush for rotary motion relative to each other to bring the sweets into brushing contact with the respectively opposed bristles. The sweets are poured into a hopper 23 at the higher end of the inclined drum 10 and descend into the space between the inner brush 11 and the cylindrical brush assembly 13 and proceed by gravity along the inside of the drum till they emerge in a discharge shoot 26. The cylindrical brush asembly 13 comprises a pair of annular end frames 38 connected by channel bars 39 and rotatable on rollers 41 mounted inside the end plates of the drum. Brushes 12 are clamped to the end frames and extend from one to the other with their bristles facing inwards, and brushes 49 are clamped to the bars 39 with their bristles facing outwards. The brush assembly 13 and the brush 11 are both driven from a motor 16 through a belt 44 and gearing whereby they are rotated in the same direction, the inner brush rotating faster. The starch is removed from the sweets by the interaction of the brushes and falls between brushes 12 to the interior of the drum, whence it is swept round by the brushes 49 as they move with the brush assembly 13 and is drawn by a suction fan 56 through a slot 50 in the drum and through the hollow trunnion structure 14 into a bag. The slot 50 extends the full length of the drum and is covered by a manifold 55. Extra long bristles 40 keep the sweets evenly dispersed round the inner circumference of the brushes 12. To achieve different brushing effects as the sweets pass through the drum the inner brush may be in sections 11a, 11b, 11c of different character and the first section 11a may be tapered to prevent the sweets from piling up. The position of the inner brush may be adjusted with respect to the brushes 12 by swinging its shaft 30 about pivots 33, 37, the. shaft being carried by an arm 32 at one end and by the gear housing 36 at the other end. 32 and 36 are connected by a T bar 27. The inner end of the pivot post 37 has a flange with slotted openings whereby it may be clamped to the end of the drum to fix the position of the brush 11. The trunnions of the drum are mounted in a split bearing to enable its tilt to be adjusted, and the pedestal which supports the mounting may be provided with castors.

Title: Improvements in and relating to recording apparatus
Inventor: HALLIDAY WILLIAM
IPC: G01S1/72
Filed: 1958-07-16
Abstract: 852,566. Echo-sounders. KELVIN & HUGHES Ltd. July 6, 1959 [July 16, 1958], No. 22891/58. Class 40(7). [Also in Group XIX] In recording apparatus an arm carrying a recording element is coupled to the rotor of an electromagnetic drive device which, when energized, sweeps the arm over a recording medium to provide a time-base, positioning members releasably hold the recording element in a predetermined zero position, the drive device is energized by a current pulse of less duration than one time-base sweep, and further members restore the recording element to its zero position after executing each sweep. The record may be intensity-modulated by applied signals and the recording element may be in contact with or spaced from the record medium. The invention is described as applied to the recording of echoes from a small range of depth adjoining the sea bed which may also be displayed on a cathoderay tube as described in Specification 785,001. Echo sounding apparatus 10 provides a pulse which triggers gas-filled triode 12 and capacitor 13 discharges through motor 14 stator winding 27 thus rotating stylus arm 17. In its rest position the stylus engages the surface of chromiumplated steel strip 20 which protects paper 18. Shaft 23, Fig. 2, carries an aluminium vane 28 moveable through gap 29 between the poles of permanent magnet 30 mounted for sliding radially of the shaft by screw 31. A small permanent magnet is embedded in the vane to determine the zero position of the stylus arm, Fig. 3 (a) (not shown). For manual zero setting of the stylus arm knob 48 is depressed until rod 49<SP>1</SP> is clear of slot 52 and can slide over the surface of annulus 53 to engage the stylus arm by finger 51, see also Fig. 4 (not shown). Movement of the rod out of the slot opens switch 55 to prevent recording during resetting. The aluminium vane 28 and the stylus arm are each counterbalanced, Fig. 3 (a), (b) (not shown). In another embodiment the stylus-driving motor has two armature windings one of which is fed with a delayed pulse to return the stylus arm to its zero position at the end of the sweep over the recording paper, the hollow stylus arm carrying a ferro-magnetic wire to hold it at a zero position determined by a permanent magnet, Fig. 5 (a), (b) (not shown). In a further embodiment a motor is provided with a helical spring tending to hold the stylus arm against a spring- loaded buffer, an impulse from the echo sounder causing the motor to overcome the helical spring force to sweep the stylus over its time-base, Fig. 6 (not shown).

Title: Removing projections from molded products
IPC: B29C37/02
Filed: 1956-07-27
Abstract: 825,879. Trimming moulded articles. AIR REDUCTION CO. Inc. July 27, 1956 [Oct. 18, 1955], No. 23337/56. Class 87(2). [Also in Groups XIII and XXIII] Flash or other projections are removed from moulded rubber articles by tumbling them in a drum having a removable cover 13 whilst cooling them by supplying liquid carbon dioxide to the drum and decreasing the pressure in the drum to rapidly convert some of the liquid carbon dioxide into vapour and solid snow. In operation, valves 36, 38 are opened to allow liquid carbon dioxide to flow from a tank 31 to a pipe 41 and into the drum through orifices 44. Simultaneously with or shortly after the opening of the valves 36, 38, the drum is rotated by a motor 27. When the pressure in the drum, as indicated by gauge 69, reaches about 55 lbs. per sq. inch gauge, a valve 64 is opened and a compressor 57 is started. When the pressure is 65 p.s.i.g. the valve 38 is closed, and the valve 47 opened to feed the liquid carbon dioxide from the tank to the drum through openings 20 of increasing diameter. The valve 47 is then closed, a valve 67 opened, and a low stage compressor 55 started which causes the pressure in the drum to decrease rapidly and the liquid carbon dioxide boils and is rapidly converted to fine snow and vapour, the temperature dropping to about -110‹F. After a period of tumbling at this temperature, the motor 27 is stopped and the finished articles removed. If the pressure in the drum is still so high that the drum can not be opened quickly, a valve 71 is opened. A purge device 62 removes air from the system. A safety bursting disc 70<SP>1</SP> is provided. In a modification, the pressure in the drum may be increased by closing the valve 36 and opening valves 46 and 38 to allow carbon dioxide gas to flow from the tank 31 through pipe 45 to the orifices 44. In a further modification, only a part of the liquid may be converted to vapour and snow by returning some of the liquid carbon dioxide in the drum to the storage tank. U.S.A. Specifications 2,380,653, 2,682,732 and 2,689,713 are referred to.

Title: Method and Apparatus for Effecting Hydrostatic Extrusion of A Billet
Inventor: LOW ARTHUR HARROLD
IPC: B21C23/00
Filed: 1966-05-26
Abstract: 1,160,247. Extruding. NATIONAL RESEARCH DEVELOPMENT CORP. 2 Aug., 1967 [26 May, 1966], No. 23691/66. Heading B3P. In the hydrostatic extrusion of a billet 11 through a die 13 the hydraulic force acting to extrude the billet is decreased as the extrusion speed increases. Billet 11 is surmounted by a disc 14 having a central recess 24 producing an annular area of contact 25 with the billet. An annular gap 17 exists between the disc 14 and chamber 12 and one or more through passages 20 are provided for passage of pressure liquid 23. The liquid is pressurized by a plunger 22 and during extrusion a pressure is produced in the annular space below the disc 14, which pressure depends upon the size of the passages 20 and the extrusion speed. This pressure acts upwardly on the disc 14 and increases with the extrusion speed thereby causing a corresponding decrease in the net extrusion force. The cap 14 may be a close fit in chamber 12 or may have peripheral slots. In a modification, Fig. 3 (not shown), the upper end of the billet (40) is sealed in the recess (41) of the disc (35) by a '0' ring (42). Flow through the passages (42) ,  (43) is adjustably controlled by screws (44) which also enable removal of air from the chamber below the disc before extrusion commences. In another embodiment, Fig. 2 (not shown) an annular billet (31) is extruded between the die 13 and a mandrel carried by the disc 14.

Abstract: 689,688. Hydraulic machines. BRITISH MESSIER, Ltd. Sept. 13, 1950 [Sept. 14, 1949 ; Nov. 21, 1949], Nos. 23746/49 and 29783/49. Class 69 (ii). Leakage of working fluid from the pressure to the return side of a motor element, e.g. a jack piston 24, Fig. 2, is effected through a narrow aperture 57 and a passage 53 in series therewith controlled by a valve 54 which is normally held closed during movement of the piston and is opened at the end of the stroke, the valve port being of greater crosssectional area than the aperture 57. The valve 54 is opened against a spring 55 by a lifting member 58 itself actuated by a tappet 60 connected to a sleeve 62 by a cross-pin 61 slidable within a slot 63 in the piston rod 25. The leakage fluid exhausts through a space 65 to a line 19. In a modification the valve comprises a ball floating between two springs and the lifting member is eliminated. In a further modification wherein leakage through the piston 24, Fig. 3, is controlled from the other end of the jack the narrow aperture comprises a bored plug 72 at the end of the space 65 and in a still further modification a spring- biased lift valve is operated by a solenoid energised automatically at the end of the piston stroke. The controlled leakage serves to prevent freezing of the working fluid, and in operation a supply pump 11, Fig. 1, draws fluid from a sump 21 and delivers it through a by-pass valve 13 and a distributer 15 to the lower side of the piston 24 which at the end of its stroke allows restricted flow through a line 18, the distributer 15 and a line 20 back to the sump 21. An electrically-driven auxiliary pump 30 may replace the pump 11 and draw from the sump 21 through a duct 36 and deliver through a line 37 and the valve 15 to one or other side of the piston 24. The leakage construction may be applied to a jack having a locking device as described in Specification 527,225.
