Title: Power drive for chain conveyor assembly
Inventor: ZEBARTH RALPH STAFFEN
IPC: B65G23/00
Filed: 1957-02-13
Abstract: 808,111. Driving gear for endless conveyers. JOHNSON EQUIPMENT CO., G. Feb. 13, 1957, No. 4854/57. Class 78 (1). An endless conveyer consisting of a series of carriages 12 running in a track including straight sections 10b, 10c and an arcuate section 10a is driven by a disc 48 mounted on a driven shaft 46 and provided with pivotally-mounted driving elements 64 which engage depending stems 16 of the carriages and have their pivotal movements controlled by cams 80, 82. An endless chain 20 interconnects the various carriages 12 by attachment of the horizontal links of the chain to the stems 16, the latter having means for suspending articles. The elements 64 each consist of an upper and a lower dog 68, 70 mounted at opposite sides of the disc 48 on a pivot pin 66 and having driving faces 78 engaging the stems 16 above and below the chain 20. The inner ends of the dogs 68, 70 are connected together by a boss passing through a slot 74 in the disc. A roller 76 on the upper end of the boss co-operates with cam surfaces 90 and 92 on cams 80, 82 respectively. The arrangement is such that the elements 64 pivot freely until their rollers 76 are trapped between the lead-in surface 90a of cam 80 and the surface 92 of cam 82 which causes the dog surfaces 78 to gradually engage the stems 16. The elements 64 remain in full engagement over the arcuate section 10a of the track and are then gradually disengaged from the stems 16 by roller 76 travelling over the end surface 90c of cam 80.

Title: Improvements in or relating to apparatus for measuring the frequency of operation ofelectric contacts
IPC: G01R31/327
Filed: 1944-03-16
Abstract: 584,311. Indicating speed or rate of flow. GRASEBY, R. C. March 16, 1944, No. 4934. [Class 40 (i)] [Also in Group XIX] The invention comprises apparatus for indicating the frequency of operation of electric contacts. This operation may be caused by the rotation of a body or by the flow of a fluid, the apparatus then being a speedometer or a rate-of-flow meter respectively. A constantspeed motor 1 drives the first member 3 of a differential gear, the second or planet member of which is carried on an arm 12 fixed to the shaft 13 to which are also secured a brake disc 15 and a cam 14. The third member 4 of the differential is attached to the sleeve 5 of a brake disc 6. A pointer 25 is driven from the cam 14 through an arm 19 and gearing 23, the pointer spindle having a friction disc 26. An electromagnet 11 is energized by impulses generated by the contacts (not shown) which in the case of a flow-meter are operated at a frequency corresponding to the rate of fluid flow, the electromagnet rotating clockwise a lever 10 pivoted at X. A brake pad 16 on an arm 17 of the lever is thus applied to the disc 15 to arrest the cam 14 and planet arm 12. Another brake pad 7 on a spring arm 9 of the lever 10 is simultaneously freed from the disc 6 to release the third differential wheel 4 which is then driven idly by the motor 1. Finally, the lever 10 removes a brake pad 27 from the friction disc 26 on the pointer spindle to allow a spring 21 to bring the arm 19 into engagement with the cam 14 and to move the pointer to a new position if the reading has increased. When the impulse passes the electromagnet releases the lever 10 which is then restored by its spring 42 to brake the pointer spindle again and to remove the brake from the disc 15 and cam 14. The brake pad 7 is temporarily held. away from the disc 6 by an arm 31 latched by a latch 36, a spring 18 then restoring the cam 14 to ;zero position where a pin 40 trips the latch 36, releasing the arm 31 and allowing the spring 9 to bring the brake pad 7'once more into contact with the disc 6. Specification 549,965, [Group XXXV], is referred to.

Title: Improvements in fuel injection pumps for internal-combustion engines
IPC: F02M59/00
Filed: 1941-04-18
Abstract: 548,711. Fuel-injection pumps. COSTA, H. DA, and PLESSEY CO., Ltd. April 18, 1941, No. 5068. [Class 102 (i)] In a fuel-injection pump for internal combustion engines the pump chamber is formed between two interconnected parts 12, 13 of the plunger which are movable axially relatively to one another during each stroke of the plunger to vary the size of the pump chamber which communicates, or at required times is brought into communication, with an inlet port 17 and an outlet port 18 fitted with a non-return valve. The plunger parts 12, 13 are normally separated to the maximum extent by means of a spring 23 so as to provide a pump chamber of constant size when this chamber is opposite the inlet port 17. The plunger part 12 is reciprocated with a constant stroke by means of a cam 14, and movement of the plunger part 13 is limited by an adjustable stop 25 when the pump chamber is opposite the outlet port 18. The stop 25 may be replaced by a cam, and such stops or cams of a multiple unit may be interconnected for simultaneous control. A vent 27 may be provided in the cyclinder 11 beyond the outer end of the plunger port 13, and a port 28 may be provided opposite the inlet port 17 to act as a bleed for gravity-fed fuel, or to pass on fuel under pressure to another pump cylinder, or back to a supply pump. In a modification, the inlet and outlet ports are directly opposite one another and each is provided with a non- return valve.

Title: Scatterplate
IPC: G01B9/02
Filed: 1969-01-31
Abstract: 1,248,344. Scatter plate: interferometry. PERKIN-ELMER CORP. Jan.31, 1969 [Feb.5, 1968], No.5421/69. Heading G2J. A scatter plate 14, for use in scatter fringe interferometry testing of mirrors, has two sets of scatter points, e.g. 26, 36 and 29, 39, symmetrically disposed about a common centre point O and has an anti-reflection coating on each side. A glass substrate has a photographic film on one surface to form the scatter plate 5, Fig. 5. The plate 5 is held against an aperture by a holder 64, 77, upper and lower surfaces 65, 66 of holder 64 being parallel to an accuracy of 1 to 2 seconds of arc. The lower surface 66 rests on rolls 71, 72 on a levelling bar 73. The plate is exposed to laser light which has passed a neutral density filter and a diffuser screen. After exposure the plate is rotated exactly 180 degrees before re-exposing whereafter it is developed, washed and bleached, dried and then given an anti-reflection coating on both sides. A pair of cross-wires 68, 69 located in the aperture, but out of contact with the plate form a fiduciary mark 43, 44 on the finished plate the cross-point of which when they are correctly aligned forms the common centre point 0 of symmetry. In testing a concave mirror the mirror is located in the focal plane of a lens. Light from the lens is reflected from a 45 degree beam splitter on to the scatter plate at the focal plane of the mirror. Thus light from a scatter point in an upper quadrant of the scatter plate gives rise to specular and scattered light which is reflected from the mirror back to focus in the opposed lower quadrant of the scatter plate at an identical scatter point. This gives rise to superimposed beams of light which interfere and the interference can be observed or recorded.

Title: Process for preparing copolymers
IPC: C08L23/16
Filed: 1963-02-11
Abstract: A cross-linkable copolymer of at least one alpha-alkene and at least one non-endocyclic hydrocarbon containing at least 7 carbon atoms, at least two non-conjugated double bonds, and no vinyl group, is made by copolymerizing a mixture of the monomers in the presence of a Ziegler-type polymerization catalyst, by maintaining during the reaction the gram molecular concentration of the non-endocyclic hydrocarbon at least 5 times that of the polymerized non-endocyclic hydrocarbon.  The non-endocyclic hydrocarbon may be obtained by dimerizing or trimerizing isoprene, butadiene-1,3, or pentadiene-1,3, with a Ziegler-type catalyst and adding the undeactivated mix directly to the polymerization zone.  The term " non-endocyclic " compound means a compound that does not contain a bridged ring, i.e. does not contain a ring having a bridge joining nonadjacent carbon atoms and containing one or more methylene groups.  The " non-endocyclic " compound may be cyclo-octadiene-1,5, cyclo-dodecatriene-1,5,9, an aliphatic polyunsaturated compound such as octadiene-2,6, or Diels Alder condensation products of isoprene and/or cyclopentadiene, e.g. indene.  The copolymerization is generally effected in a hydrocarbon or halogenated hydrocarbon liquid vehicle.  Examplified catalysts are monoethyl aluminium dichloride and VOCl3, and TiCl4 and di-isobutyl aluminium hydride.  The alphaolefines may be ethylene, prpylene, butene-1, pentene-1, hexene-1, heptene-1, or mixtures, e.g. ethylene with propylene and/or butene-1, or a mixture of ethylene and/or alpha-methyl styrene.  The copolymers may be vulcanized using conventional sulphur-containing mixes.
