Title: Improved dough-rolling machine
IPC: A21C3/02
Filed: 1960-02-22
Abstract: 877,161. Rolling dough. SEEWER, G. A. Feb. 22, 1960 [March 3, 1959], No. 6106/60. Class 87(2). [Also in Group XXIV] A machine for rolling dough comprises a pair of superposed cylinders 2, 3 which are driven in opposite directions and which may be reversed, a driven endless conveyer 15, 16, on the feed and delivery sides of the machine, and a drive mechanism which connects the cylinder and the conveyer drives including, a primary clutch 20, Fig. 5, operating with or without slip depending on its direction of rotation so that during the rolling operation the drive member on the delivery side operates without slip while the drive mechanism on the delivery side operates with slip, each of the two primary clutches being provided with secondary clutches 29 which operate without slip when engaged, and means which hold the secondary clutch in engagement when the cylinders are not acting on a lump of dough. As shown, Fig. 2, when the cylinder 3 is lowered by the absence of dough between the cylinders, an interconnecting eccentric 10 in turn lowers a shaft 8. This movement pivots an arm 43, Fig. 4, about a pair of fulcrums 42 thereby moving the dog clutches 30 into engagement with a pinion 33 whilst continuing to engage the primary clutch 22. Thus the cylinder 2 drives the rollers 13, 14, in a positive manner through a train of gears 17, 19, 22, 29 and 30. In a modification to control the amount of slip of the feed conveyer the springs 25, Fig. 5, of the clutch 22 are removed so that the clutch is either locked whilst rotating in one direction or completely free whilst rotating in the opposite direction, the idlers 19 being replaced by an adjustable single plate clutch 19, 51 (not shown). Thus the amount of slip required can be controlled by the adjustable plate clutch 19, 51 (not shown). In a further modification, the dog clutches 30 can be actuated by an interconnecting yoke which can be attracted by an electro-magnet which is controlled by a pilot switch operated by the vertical movement of the shaft 8. Specification 749,970 is referred to.

Title: Improvements in and relating to the automatic operation of the variable speed gears of vehicles
IPC: F16H59/50
Filed: 1925-03-07
Abstract: 235,815. Holmes, G. E. March 7, 1925. Addition to 232,437. Automatic gear control. - The change-speed gear and the clutch are automatically operated according to the gradient by a pair of weighted arms 1, 2 swinging loosely on a pin 3 carrried by a casing 4 fixed to some part of the vehicle. Teeth 18 on the lower ends of the arms engage a pawl 19 carried by the casing. When the vehicle is on a gradient and the casing consequently rotates, the arm 1 at first swings with the casing but the arm 2 is stated to remain vertical and one of its teeth acts on the pawl 19 and disengages the latter from the arm 1. The arm 1 then swings back to the vertical position and in doing so rotates a shaft 5 through bevel gear 20 and operates the change-speed gear and clutch rod 12 by means of an eccentric 7 on the shaft. Each tooth on the arm 1 corresponds to one ratio of gearing of the change-speed gear. The casing 4 is connected to a fixed part of the vehicle by a sleeve 9 and can be rotatable adjusted relatively to this sleeve by means of a locking arm 8.

Title: Process of manufacture of an abrasive substance and an abrasive substance obtained by this process
IPC: B24D18/00
Filed: 1962-02-19
Abstract: Abrasive materials are produced by mixing particles of hard substances having a number of 8-10 on Moh's scale, such as powdered diamond, ruby, sapphire, tungsten, chromium, silicon or boron carbides, or mixtures of metal carbides with diamond powder with a relatively high melting hard solder, e.g. eutectic Cu/Ag alloys, and heating the mixture in an inert atmosphere, e.g. of argon or helium, in contact with titanium or zirconium at a temperature high enough to melt the solder and to dissolve therein titanium or zirconium.  The hard substances may be diluted by the presence of metals having a melting point above that of the brazing temperature in the form of powder or small lumps, e.g. nickel, iron or tungsten.  The titanium or zirconium may either be added to the materials to be heated in the form of a powder and the mixture heated in a refractory or metal crucible, or the mixture of hard substance and alloy heated in a support of titanium or zirconium.  A homogeneous abrasive mass of any desired shape may be obtained.

Title: Phonograph
IPC: G11B3/095
Filed: 1965-02-15
Abstract: 1,124,591. Pick-up arms. H. C. HANSEN. 11 Feb., 1966 [15 Feb., 1965], No. 6451/65. Heading G5R. The swinging movement of a phonograph pick-up arm 10 from a position outside the edge of a record to a start-of-play position is obstructed by a brake plate 16 which is pivoted on a pair of ball points 28 and urged downwardly by a spring 30 into contact with abutments 22 on a reciprocable lever 24. A rotatable cam disc 14 is provided on its undersurface with a track 60, Fig. 5, engaging a pin 62 on a lever 64 having a cam 66 to control the raising and lowering of pick-up arm 10. When cam 14 rotates in the direction of arrow C it releases a pin 36 on a member 18 from a slot (40), Fig. 4 (not shown), in cam disc 14 to allow member 18 to move in the direction of arrow A under the influence of a spring 34 until a pin 98 on member 18 engages an abutment on disc 94. Member 18 has a oam surface 20 which engages abutment 22 on reciprocable lever 24 and thus causes swing- ing movement of pick-up arm 10 inwardly to its start-of-play position. On completion of this swinging movement a pin 100 on the underside of brake plate 16 engages a cam member 102 on cam disc 14 so that brake plate 16 is tilted and the brake becomes ineffective.

Title: Improvements in or relating to indicators for fire extinguishers and like liquid spraying apparatus
Inventor: SANKEY JOHN BRUNDRIT
IPC: A62C37/50
Filed: 1955-03-07
Abstract: 829,184. Fire extinguishers. NATIONAL RESEARCH DEVELOPMENT CORPORATION. March 7, 1956 [March 7, 19551, No. 6596/55. Class 47 [Also in Groups XVIII and XXVIII] An indicating device for a spraying apparatus in which liquid is discharged from a container under pressure, consisting of a unitary structure which includes a gas pressure indicating member and a float, the position of the gas pressure indicator being controlled by the gas pressure in the container and the float serving to indicate the quantity of liquid in the container. In a fire extinguisher having a closure member 3, a valve 13 secured to a tube 9 is normally held upon its seat 14 by gas pressure within the flask assisted by the pressure of a light spring 18 on one side of a plate 16 attached to the tube 9 and opposed by a stronger spring 17 on the other side of the plate 16, the arrangement being such that in response to a reduction in pressure in the flask due to leakage of gas the valve 13 and the tube 9 are moved downwardly by the spring 17 so that an enlarged head 19 of the tube 9 occupies a position below a guard member 21 to serve as a visual indication of loss of pressure. Within the tube 9 is provided a float 20 which can be observed through a transparent part of the tube 9 at its upper end. In the event of leakage of liquid the float 20 sinks and is no longer visible. The tube 9 is provided with holes 27, 28, whereby when the tube moves to its depressed position in response to leakage of gas, the lower hole 27 moves into the upper part of the flask which is thereby placed in free communication with the atmosphere. In order to operate the extinguisher, the guard 21 is pivoted to the side (Fig. 4) so that a slot 22 in the guard embraces the tube 9. The tube 9 is then manually depressed to open the valve 13, its downward movement being limited by engagement of the head 19 with the sides of the slot 22 so that the hole 27 does not move into the flask. The liquid is then forced up the tube 9 past the valve 13 and through the nozzle 26. Due to fall in pressure in the flask upon discharge, the spring, 17 maintains the valve 13 open without further manual assistance. The head of the tube, or the float, may be used to control an indicating disc or the like. When charging the flask the closure member 3 is fitted after the liquid has been introduced and a cap 15 on the closure member is moved into an upper position in which the pressure on the spring 17 is relieved while gas is introduced through the nozzle 26 until a pressure has been built up in the flask enabling the cap 15 to be moved into its lower position.

Abstract: 558,076. Pins. LEYLAND MOTORS, Ltd., and CHARNOCK, A. J. May 15, 1942, Nos. 6638 and 9552. [Class 24] [Also in Groups XXXI, XXVI and XXXIV] Means for retaining a shaft in a bearing or a pin 2 in its socket 4 comprise a rubber plug 3 or 17 having a collar 7 adapted to fill an annular recess 6 in the socket or bearing, the plug being of such size or form that the collar thereon can be compressed or deformed to pass into the socket or bearing and expand into the annular recess. In the construction shown in Figs. 2 and 3 applied hinge-pins 2 of an endless-track, the plug 3 is a sleeve on a metal core 1 having a groove 12 into which the collar part of the plug can be compressed when the plug is being inserted in the socket. To insert the plug a tool 8 shaped as shown in Fig. 2 is used, its inner end, being inserted in the socket 4 and the plug pushed in until the collar can expand into the recess 6. The inner end of the core is rounded to minimise the area of contact with the pin 2. In the construction shown in Fig. 5 the rubber plug 17 is solid and is sufficiently flexible to permit the collar to be contracted within the diameter of the socket when the plug is being inserted. A rounded metal plate 16 is provided to make contact with the end of the pin. Modifications are described in which (1) the rubber sleeve 3 is thicker than shown in Figs. 2 and 3, and the core 1 is correspondingly smaller in diameter, and the groove 12 is dispensed with, the greater thickness of the rubber allowing the collar to be contracted sufficiently to enter the socket, and (2) the rubber sleeve is initially cylindrical but is forced on to a core 19, Fig. 7, having an enlarged inner end, until the inner end 24 of the sleeve is expanded to form a collar.
