Title: Improvements in self-operating mechanisms for retarding the movement of an object down an inclined runway
Inventor: COWAN HENRY
IPC: B65G13/00
Filed: 1965-03-01
Abstract: 1,083,082. Roller conveyers. ISO-SPEEDIC CO. Ltd. May 31, 1966 [March 1, 1965], No. 8660/65. Addition to 1,024,936. Heading B8A. [Also in Division F2] The wheel or roller 17 of the parent Specification is provided not only with a narrow passage (30), Fig. 4 (not shown), interconnecting parts of a chamber 26 on either side of sun and planet wheels 27, 28 acting as a gear pump, which passage (30) provides a continuous braking effect, but also with a second passage 32, (33), (34), Fig. 5 (not shown), having a throttle valve comprising a ball 38 urged away from its seating (37) by a spring (39). At low rotational speeds the pump pressure differential is insufficient to close the throttle valve so that oil is pumped through the two sub-circuits formed by passages 30 and 32, (33), (34). These subcircuits provide a resistance which increases as the speed increases, part A of the curve in Fig. 7. When the load on the roller exceeds a certain value the pressure differential acts to close the throttle valve so that the second sub-circuit 32, (33), (34) is closed and oil can only flow around the first sub-circuit 30. This introduces a sudden increase in resistance, part B of the curve of Fig. 7. Subsequent increase in rotation speeds increase the resistance according to part C of the curve of Fig. 7. In this way light loads are able to reach a reasonable velocity but appreciably heavy loads are not able to reach an excessive velocity. The passage 30 may be eliminated, the ball 38 reaching a stop before closing the passage 32, (33), (34). Alternatively the high resistance may be provided by the necessary small clearances in the pump. In an alternative embodiment, Figs. 8 to 11 (not shown), a sun-wheel (59) co-operates with an internally toothed rotor (61). Two kidneyshaped slots (63), (64) are interconnected by a sub-circuit consisting of bores (66), (67), (69) and are each fitted with a leaf spring (71) one end of which forms a closure member overlying the entrance to the corresponding bore (66) or (67) but is held away to a limited extent by a screw (74) and by means of a spring (75). In this case the device operates in either direction.

Title: Improvements in or relating to resilient suspension springs
Inventor: SEDDON ROBERT MAXWELL
IPC: B60G3/18
Filed: 1951-04-14
Abstract: 703,641. Rubber springs. DUNLOP RUBBER CO., Ltd. April 4, 1952 [April 14, 1951], No. 8731/51. Classes 103(6) and 108(3) A resilient suspension spring comprises a plurality of resilient members 21, 25, 26 adapted to be compressed in series, by a predetermined value of relative movement in one direction, of loading members 2, 13, and means whereby displacement of the members 2, 13 beyond the predetermined value causes compression of the members 21, 25, 26 in parallel. In operation of the construction shown in Fig. 1 under tension, initially the members 21, 25 are stressed in series and the member 26 is unstressed. When a backing washer 23 of the resilient member 25 . engages an abutment 5 of the member 2, an abutment 18 on the member 13 engages a backing washer 22 of the resilient member 21. This results in the resilient members 21, 25 being stressed in parallel. On further movement, a backing washer 27 of the resilient member 26 engages an abutment 4, and all three resilient members 21, 25, 26 are stressed in parallel. On recoil, the resilient member 21, only, is loaded. Any number of resilient members above a minimum of two, may be employed, and they may be disposed side-by-side. Instead of a two-piece tubular member 2, as shown, held together by the threaded abutment 4, the member 2 may be a one-piece tube with the abutment 4 welded in position. The spring may be so dimensioned that a metal spacer ring 29 between the washers 22, 23 is not needed. Rubber annuli 24. 24', 31, are bonded to the washers 22, 23, 27. The spring may be used in the suspension of a rail-vehicle bogie wheel, Fig. 2, or in road vehicle suspension, or in trailer vehicle ,drawgear.

Filed: 1926-04-06
Abstract: 250,579. United Shoe Machinery Corporation, (Assignees of Kelly, J. A.). April 7, 1925, [Convention date]. Cutting-out apparaius.-The flap of the shoe sole which is secured to the breast of a Louis or like heel is cut to conform with the outline of the breast surface before the securing operation. Prefeiably, this cut is made in the sole blank before the sole is split, the subsequent splitting severing the horse-shoe shaped remainder. A suitable cutting-machine comprises a table E provided with a holder F for the sole blank and a crosshead H carrying a die G. The cross-head is normally raised by springs h<2>; and is depressed, on the cutting stroke, by a treadle h<3>. Preferably, the die is adjustable, comprising a rear portion g, Fig. 2, adjustable longitudinally of the sole by a slot and screw g<3>, and side portions g<1> adjustable towards and from each other by a right-and-lefthand screw. After the rear end of the sole is split, Fig. 3, a lip a, Fig. 4, is left by gashing the sole, which lip is compressed against the edge c<1> of the heel by a plunger I. The flap B is finally secured, as usual, to the heel breast. Specification 244,452, [Class 17 (i), Boots and shoes, Apparatus for making &c.], is referred to.

Filed: 1959-03-17
Abstract: 863,698. Starting fuel injection engines. BOSCH G.m.b.H., R. March 17, 1959 [March 26, 1958], No. 9114/59. Class 7(3). [Also in Group XXVIII] A fuel injection pump piston 4 is supplied with liquid through ports 43, 42 and a throttle 41 by a feed pump 38 driven by the engine and controlled by a valve 48 such that the discharge pressure varies according to the engine speed. The feed pressure acts against the action of a spring 20 above a slidable sleeve 3 which controls spill from a port 25 in a portion 5 of the piston. On starting the feed pressure is insufficient to move the sleeve 3 and the pump discharges maximum fuel; thereafter the feed pressure increases and varies the position of the sleeve 3 between limits set by a pin 52.

Title: Improvements relating to materials and articles made from bonded inorganic fibres
Filed: 1940-05-31
Abstract: 540,342. Synthetic resins. GLASS FIBRES Ltd., and HALLAWELL, A. M. May 31, 1940. No. 9571. [Class 2 (iii)] [Also in Group VIII] The synthetic resin content of materials or articles comprising loosely felted inorganic fibres such as glass fibres bonded by a heathardenable synthetic resin is hardened in such a manner as to render the whole or part of at least one of the surfaces rigid leaving the main body of the material resilient or flexible. The synthetic resin is sprayed in water-soluble form on to the fibrous mat and the solvent evaporated. If desired the surface to be rendered rigid is sprayed with additional synthetic resin. Hardening is effected by contact with a hot surface under slight pressure, the opposite surface being supported by a cold surface. The surface may be rendered rigid in strips by leaving alternate strips unhardened or partially hardened, by spraying on additional resin in strips, by bonding treated strips of the material to the surface or by forming the surface with ridges which are flattened during hardening. The product may be united by its unhardened surface to an untreated mat of inorganic fibres. The Provisional Specification describes also the use of thermo-plastic substances such as bitumen, shellac and cellulose derivatives.
