Title: Improvements in or relating to vehicle brake systems
Inventor: SKOYLES DEREK ROBERT
IPC: B60T8/34
Filed: 1964-04-21
Abstract: 1,101,078. Fluid-pressure brakes. MULLARD Ltd. 12 Feb., 1965 [21 April, 1964; 30 July, 1964], Nos. 16474/64 and 30214/64. Heading F2F. An arrangement for facilitating control of brake pressure in a vehicle hydraulic braking system by anti-skid devices, comprises a control piston B1 arranged to operate in a cylinder having large and small diameter bores separated by a shoulder R and which is located between a master cylinder connection MC and a wheel brake cylinder W, a rod C through which movement can be imparted to piston B1 to move it from the position shown, where fluid is free to by-pass it, to a position beyond the shoulder R where the fluid supply is cut off, whereby continued movement forces fluid back to the master cylinder and allows fluid to flow away from wheel cylinder W, and a positive feedback arrangement between the master cylinder connection MC and the piston B1 which consists of a second piston Bf subjected to master cylinder pressure and acting via a suitably shaped cam or equivalent force-balancing member FB on the rod C. The arrangement is such that the forces acting on piston B 1 are balanced or nearly balanced at all times so that only a small additional force, e.g. one produced by an electromagnet energized in response to a signal from a skid-sensing device, is needed to move the piston B1, while resulting in a much greater transfer of energy away from the wheel cylinder than that which is expended in moving the piston B1. The energy transferred away from the wheel cylinder W on operation of the antiskid device is shown, by mathematical formulµ, to be only partially expended in moving the piston Bf which has a smaller bore X stroke than that of piston B1. The remaining energy is transferred either to the master cylinder (Fig. 4, not shown) which would result in undesirable kick-back of the driver's pedal, or preferably, as shown in Fig. 5, to a spring S1 It is shown mathematically that spring S1 cannot absorb all the surplus energy at every position, so that the alternative arrangement of Fig. 6 may be preferred, in which the fluid displaced by piston B1 is exactly compensated by a second, gauged, piston B2, a spring S2 acting between piston Bf and the cam FB then operating as a non-linear energy absorbing device. Spring S2 may be replaced by an accumulator bulb S2(a). A single piston having a valve arrangement (Fig. 7, not shown) operating in a plain bore without shoulders R, R<SP>1</SP> may be substituted for the arrangement shown in Fig. 6. Fig. 8 (not shown) is a modification of the arrangement of Fig. 7. Figs. 9 and 10 (not shown) disclose modifications of the simpler arrangement of Figs. 4 and 5 to reduce pedal kick back in this case. A suitable electromagnetic actuator for moving the rod C in response to electrical impulses is indicated diagrammatically in Fig. 11 (not shown), the impulses being supplied, after amplification, by a magnetic sensing unit indicated diagrammatically in Figs. 13 and 14 (not shown).

Title: Improvements in or relating to electric circuit control means
IPC: H02P7/08
Filed: 1927-06-21
Abstract: 287,041. Ritter Dental Manufacturing Co., Inc., (Assignees of May, A. J.). March 12, 1927, [Convention date]. Retractive switches; switches. quick-action. - An electric switch which may be employed for controlling a reversible motor for raising and lowering a dental chair has a plurality of operating elements comprising spaced sets of actuators, the actuators of each set being adapted to effect operation of the movable contact device to its different control positions. As shown in Fig. 2 the switch operating elements comprise sets of pedals 66, 68 and 67, 69 which may be operated from one or other sides of the chair to complete at will the circuit of the motor for raising or lowering the chair, the switch being automatically returned to its off position on release of the depressed pedal. The pedals 66, 67 are secured to a shaft 63 bearing a switch-operating crank 59 (Fig. 9) and the pedals 68, 69 are secured on shafts 70 bearing plates 72 having forked ends engaging pins 73 on a plate 62 carried by the shaft 63. The circuit arrangements of the switch may be of the type described in Specification 261,774, the switch itself having a sliding insulating block 32 (Fig. 6) carrying contacts 30, 31 which may be brought into engagement with one or other of sets of fixed contacts 26, 27 or 28, 29 corresponding to different directions of rotation of the motor. A quick-action mechanism for the movable contact member is provided consisting of a sliding frame 42 which carries a pin 60 engaged by the furthest end of the switch operating crank 59. The frame 42 carries an upper rod 43 surrounded by the quick-action spring 47 and a lower rod 41 surrounded by a centralizing retractive spring 57. Thus when the arm 59 is moved in a clockwise direction by depression of pedal 66 or 69 the spring 48 is compressed between collars on the shaft 43 but the frame 35 attached to the movable contact member is held from movement by a spring pressed pawl 50 engaging a groove in its upper surface. When, however, the resistance of the retaining detent is overcome by the compression of the spring 48 or by the positive action imparted to the frame 35 after further movement of the operating-member the frame 35 snaps over to the position in which the motor circuit is completed. The movement of the frame 41 also compresses the lower spring 57 against a fixed projection 40 so that when pressure on the operating pedal is released the switch is automatically returned to off position with a quick action. Depression of either pedal 67, 68 causes a similar spring-returned movement to complete the motor circuit in the reverse direction.

Title: Improvements in Means for Automatically Tipping Trucks and like Vehicles.
Inventor: JOHNSTON WILLIAM HAWTHORN
IPC: B65G67/00
Filed: 1916-11-17
Abstract: 111,322. Johnston, W. H., and Francis, C. E. Nov. 17, 1916. Rotary tipplers.-In rotary tipplers, the truck is held in place by the engagement of an axle with the ends 14 of a bifurcated lever 12, the other end of which is pulled down by a spring 18 and bears against one end of a lever 17. In order that the incoming truck may release the truck which has already been tipped, the other end 21 of the lever 17 is arranged in the path of the axles of the incoming truck. The tippler is retained in position to receive a truck by a spring catch 29 and catchblock 30 which are disengaged when the lever 34 connected to the former is actuated by the truck. The circular side plates 1 of the tippler are provided with buffers 37 which impinge on bumping-blocks 10, and the recoil, aided by gravity, brings the tippler &c. back to the position shown.

Title: Improvements in and relating to pipe joints and the like
IPC: F16L27/10
Filed: 1923-06-26
Abstract: 215,297. Watson, C. W. April 30, 1923, [Convention date]. Butt joints.-Pipe-like butt joints are formed by means which in addition to providing axial compressive forces also provide axial converging forces to render the joint tight; in addition, the packing between the butt ends may be shaped so that pressure within the pipe will also act to render the joint tighter. Opposed segments S with interfitting bevelled claws 11 and gripping claws 5 are loosely held to each pipe end in opposed relationship by spring grip means 18 or band 19 while the packing P is placed between the joint and covered by a flexible band 16. The claws 5 are adapted to grip raised rings on the pipe ends or rings clamped to the pipe ends. On tightening nuts on the bolts 9, the segments are drawn together to cause axial compressive stresses, and the bevelled surfaces 14 of the segments bearing on the raised periphery after packing causes convergent transverse stresses. In Fig. 3 are shown pipes meeting at an angle, the packing P being so shaped to admit of this, and, in addition, provide internal flange portions 22 which are expanded against the shaped inner edges of the joint by the internal fluid pressure within the pipe after the joint has been formed as previously described.

Title: Rotary baling machine
IPC: B65B27/12
Filed: 1956-05-29
Abstract: 785,586. Baling presses. ALLIS-CHALMERS MANUFACTURING CO. May 29, 1956 [June 6, 1955], No. 16635/56. Class 94(1). [Also in Group XXIV] In rotary baling presses of the kind described in Specifications 594,421 and 594,422 [both in Group I], a variable speed output shaft is provided in driving connection with both the baling and wrapping mechanisms, and a changespeed transmission (see Group XXIV), is interposed between the power shaft and the variable speed output shaft to automatically drive at a low speed for the baling operation and at a high speed for the bale wrapping operation. The material passing between rolls 3, 4, is engaged by bale rotating mechanism 20 including endless bale forming bands 22 and 24 and rolled into a compact cylindrical bale 68 and when the bale attains a desired diameter the conveyer 43 is stopped automatically and latch release bar 19 is actuated to lift latch 37 on arm 11 whereupon upper and lower trip roll assemblies 7, 16 move apart, ejecting the bale rearwardly from between the bale forming bands 22 and 24 and out of the machine, the trip and tension assemblies automatically returning to their initial starting positions. Mechanism for wrapping twine 70 is mounted on frame 1, including a pair of spring pressed twine tensioning disks 69 and a twine roller 71. A twine feeding member or tube 73 has on its upper end a twine guide roller 74 for conducting the twine into the tube, an intermediate cam edge portion 76 and at its lower end a twine feeding ferrule 77. A roller 189 is mounted on an arm of crank 191 which is trunnioned on a bracket of frame 1 and biassed by spring 210 so as to urge roller 189 against an internal cam surface 192 on gear 89. When the twine 70 is caught and starts to wrap about a bale, the tension of the twine causes roller 122 to swing away from stop 123. As a result gear 89 is rotated clockwise by the action of a spring so that the raised portion of cam surface 192 contacts the roller 189 and moves the other crank arm 199 of crank 191 to actuate switch 195 thereby energizing magnet winding 186 of a clutch 177 and the shaft 172 is now driven by gears 167, 176 at a substantially higher speed. Upon establishment of the high speed drive a spring clutch 169 permits gear 168 to overrun gear 167 and the high speed operation continues until the twine is severed. When this occurs the circuit to winding 186 is broken by arm 199 having moved away from the switch actuating button 195 and the shaft 172 is driven through gears 168, 171 at a slower speed.

Abstract: 434,621. Regulating - apparatus for winding-apparatus. SMITH, G. D., Clevedon, Brooklands Road, Baguley, Cheshire, and ASSOCIATED ELECTRICAL INDUSTRIES, Ltd., Crown House, Aldwych, London. June 4, 1934, No. 16645. [Class 78 (v)] A control mechanism for winding, hoisting, hauling, and other moving apparatus comprises manual or pedal control 1 for the power, manual or pedal control 8 for the brakes, and automatic emergency control 14 whereby the power, if acting, is reduced before application of the brakes and also whereby when the brakes are applied the power is not increased till the brakes are released. The mechanism comprises a floating lever 7 to an intermediate point of which the automatic control member 14 is pivoted and to the ends A, B of which are hinged links 6, 13 pivoted respectively to ends c, c<1> of floating levers 4, 11. The lever 4 is connected to the power control 5 at an intermediate point b and its outer end a is linked to an arm 2 moving. with the control 1. The lever 11 is connected at b<1> to the brake control 12, and at a<1> to a link 10 operated by the control 8. Weights 15, 16, of which 15 is the greater, are suspended from the ends A, B of lever 7. These weights may be replaced by other biassing means. In action, upward pressure by the member 14 keeps the pivots c, c<1> up against abutments 17, 18 and allows the controls 1 and 8 to function normally. Emergency retraction of the member 14 removes first the pivot c from its abutment 17, owing to the greater weight of the mass 15 relative to that of 16, thus lowering the pivot b and reducing the power. The pivot c<1> later leaves the abutment 18, lowering the pivot bl and putting on the brakes. When the emergency conditions cease and the member 14 returns the brakes are released before the power is increased. Specifications 312,113, [Class 78 (v)], and 424,223 are referred to.
