Title: Improvements in or relating to sorting apparatus
IPC: B07C5/342
Filed: 1951-07-19
Abstract: 712,113. Sorting photo-electrically. BAIGENT, G. M. July 21, 1952 [July 19, 1951], No. 17195/51. Class 40 (3) Objects to be sorted are examined by means of light rods which direct light from various parts of the object under inspection on to a single sensitive device. In the sorting device shown falling objects are guided by discs 8, 9 through a central transparent tube 11 mounted in a cylindrical holder 1. Situated between the holder interior and discs 8, 9 are a pair of gas discharge tubes 14, 15 which illuminate the object. Light from these sources is reflected either from an object in tube 10 or from a comparison background 2 to one of three holders 22 spaced around cylinder 1. Each disc houses a lens 5 focusing light through an aperture 6 on to a horizontal slit in a diaphragm through the central cylinder. The light passes through the slit to a rod 21, one end of which is fixed in holder 22 and all three rods are so bent as to direct light on to a single mixing block 25 which diffuses it evenly over the sensitive surface of a photo-electric cell 24. Shields 16, 17 prevent light reaching lenses 5 direct from the discharge tubes. The light rod may be glass or polymethyl methacrylate polished or silvered, internally polished opaque tubes or glass tubes polished either externally or internally. The viewing assemblies may be so mounted as to view the leading or trailing edges of a falling object. Objects of a particular colour may be sorted by using coloured rods or filters. The amount of light passing through a particular rod may be varied by means of a variable shutter on the end of the rod or by making the rods of two relatively movable parts. Specification 492,035 is referred to.

Filed: 1929-06-05
Abstract: 313,129. Miquet, L.. June 7, 1928, [Convention date]. Void [Published under Sect. 91 of the Acts]. Hook fastenings; locks for motor-vehicle bonnets and steering columns; sliding bolts; spring locks.-The bonnet of a motor vehicle is fastened by a hook 3 slidably mounted in a casing 1 provided with an inclined flange 6 for securing it to the bonnet, and adapted to engage a strap (not shown) on the chassis. The book is moved longitudinally by rotation of a sleeve 7, held against endlong movement by a screw 9, and having internal threads engaging threads on the hook, which is prevented from rotation by a screw 8 engaging a groove 17. The sleeve 7 can only be rotated by means of a casing 2 rotatably mounted on casing 1. Casing 2 houses plungers 11 urged by springs 14 into engagement with apertures 11<1> in the flanged end of sleeve 1, so that rotation of member 2 rotates sleeve 7 and operates the hook 3. The plungers may be withdrawn from engagement by a collar 12 movable axially by a screw 13 anchored against axial movement by a headed projection 16 thereon engaged in a recess in sleeve 7 as shewn. Screw 13 is rotatable by a projection 15 on a barrel lock 4 operated by a key 5. When the plungers are withdrawn from engagement member 2 rotates idly and the hook can only be operated by the use of the key 5 to allow the plungers 11 to engage sleeve 7. The steering-column 31 of a motor vehicle is locked against rotation by sliding a plate 35 with teeth urged by spring 36 into engagement. with a toothed ring 34 secured to column 31. The plate 35 is enclosed in a casing 32 and can be withdrawn from engagement by a key-operated barrel lock 37. Barrel 37 has a disc 38 with a projection 39 which operates a rotatably mounted disc 40 with an upstanding pin 41<2> adapted to be engaged by projection 39 and with an arm 42. When the barrel is rotated clockwise, Fig. 9, projection 39 moves round to engage the left side of pin 41<2> and then rotates member 40 to cause arm 42 to engage a projection 43 on plates 35 and withdraw the plate from engagement. When disengagement has been effected, barrel 37 has made a complete rotation and the key can then be withdrawn, thus looking plate 35 in retracted position. Movement of member 40 in anticlockwise direction is limited by a projection 44 on plate 35. Plate 35 may be further secured in retracted position by a spring-pressed plunger 45 passing through an aperture 49 in plate 35, the end of the plunger also serving to close contacts 48 in the ignition circuit. Plunger 45 may be held withdrawn by helicoidal cam surfaces 50 when the plunger is rotated by a trigger 47.

Abstract: 610,012. Ignition systems. BRITISH THOMSON-HOUSTON CO., Ltd., WELCH, D. F., and COE, R. T. Sept. 12, 1944, No. 17405. Drawings to Specification. [Class 7 (iv)] In a high-frequency ignition system in which a condenser is charged by interrupting current in an inductive circuit having primary and secondary windings, the condenser being in circuit with the secondary winding, and is discharged through the primary of a transformer, the secondary of which is connected to the sparking plug or plugs, by the breakdown of a series spark-gap and in which the breakdown is initiated in response to the current charging the condenser by de-saturation of a peaking transformer or choke, the values of the components in the part of the system which charges the condenser are so chosen that the ratio of the higher to the lower frequency components of current in the secondary is between 2.5 and 4.5 to 1. By this means it is possible to ensure that the charging current reaches zero for the first time at the moment when the voltage is a maximum. Further, by the choice of component values referred to a peaking secondary voltage wave is obtained. It is also possible to design so that the primary current energizes a bias winding on the core of the peaking transformer the winding being inserted in the lead feeding the contact breaker. The resultant circuit may be so adjusted that the peaking transformer operates before, after or exactly at voltage maximum. Specifications 529,558, 537,317, 545,857, and 598,053 are referred to. The Provisional Specification refers also to Specification 610,013.

Title: Improvements in chain or belt tensioning devices
Inventor: BAYLISS CECIL THOMAS
IPC: F16H7/08
Filed: 1956-06-07
Abstract: 810,274. Belt and chain tensioning. PERRY CHAIN CO. Ltd. March 27, 1957 [June 7, 1956], No. 17572/56. Class 80 (1). The timing chain if an internal-combustion engine is tensioned by a sprocket or slipper 9 actuated by a spring-loaded hollow piston 8 slidable in a fixed compartment 5 communicating with an oil reservoir 4 through a non- return valve formed by the end of a flexible blade 13 whose other end is riveted to the piston. As the piston 8 is moved outwardly by the spring 11 to take up slack in the chain oil flows into the compartment 5 and prevents the piston from moving back by more than a slight amount. To allow passage of the oil, a groove 7 in the inner wall of the compartment 5 or in the outer wall of the piston 8 connects a hole 6 in the bottom of the reservoir with an aperture 12 in the piston 8, said aperture being closed by the circular curved end of the steel blade 13 forming the non-return valve. The spring 11 is held clear of the blade 13 by a guiding pin 15 pressed into the piston 8. The blade 13 mav have a small calibrated hole allowing a slight return movement of the piston 8. The reservoir 4 may be replenished by splash or by a pipe in the lubricating system. 'Instead of being fixed to the piston 8 the slipper 9 may be pivoted to a fixed part and be engaged by the piston. In a modification the piston is fixed and a slipper is attached to the housing of the oil reservoir, the housing being movable over the piston under the action of a spring. In a further modification, Fig. 8 (not shown), avoiding the use of a slipper the piston 8 activates a jockey sprocket rotatable on a carrier slidable on the reservoir housing. The sprocket may have three rings of teeth to engage a triple chain and is then acted upon by a pair of parallel spring-loaded pistons. The tensioning devices described are applicable to other driving chains or belts.

Abstract: 558,677. Moulding by dipping. FAIRWEATHER, H. G. C. (Chemical Enterprises Inc.). Oct. 9, 1941, No. 17914/43. Divided out of 558,649. [Class 87 (ii)] A device for rolling a bead on the open end of a hollow dipped article or for stripping the article from its former, comprises an elongated tapered brush member pivotally supported at one end and supported at its other end by eccentric means which impart to the brush member a wobbling motion about its pivoted end. Two forms are described :-(1) The brush member A, Figs. 1 and 2, carries four brush elements 80 of felt or soft rubber, and is mounted at one end in a universal bearing 86. At the other end an eccentric shaft 87, driven by a pulley 88 ; imparts a wobbling motion to the member A, which is prevented from rotating by the engagement of a stem 94 in one of four recesses in the member. Only one brush element 80 at a time engages with the passing dipped articles. (2) The brush member 115, Figs. 3 and 6, carrying brush elements 114, is pivoted at one end in a knuckle or universal joint 116 and at its other end also in a universal joint 119 carried on a bracket 120 formed with a cam opening 121. The bracket 120 is pivoted at 122, and as cam 125 rotates the large end of member 115 wobbles and the operative brush element 114 rolls a bead on the dipped article. The amplitude of the wobbling movement is greater at the large end of the member 115 than at the smaller end, so that as the article 113 progresses past the element 114 it is brushed with longer and longer strokes, the strokes simulating hand-rolling. The cam 125 is rotated by an electric motor 126. A manuallyretracted, spring-urged rod 128 engages a selected recess 130 in member 115 to hold the latter in position. The dipped articles may be rotated while the beads are being formed.
