Filed: 1977-01-12
Abstract: 1512359 2-Styryl benztriazole derivatives BAYER AG 12 Jan 1977 [16 Jan 1976] 01145/77 Heading C2C The invention comprises compounds of Formula I wherein R is C 1 -C 4  alkyl, benzyl or C 1 -C 4  alkoxyethyl. These compounds may be made by reacting a compound II with p-phenylbenzoaldehyde in the presence of a condensing agent, e.g. a secondary amine. A 5 - alkoxybenztriazolyl - 2 - acetic acid of Formula II may be obtained (a) by reductive cyclization of a compound of with subsequent removal of the anilide grouping by treatment with alkali (this gives a mixture of N-acetic acid benztriazoles), or (b) by addition of the -CH 2 COOH group to the corresponding benztriazole by reaction with chloroacetic acid. Compounds of Formula I are optical brighteners.

[Class 80 (i).] In a machine for pressing wire hooks into driving belts of the type comprising an anvil and a pivoted press-head, the anvil has a removable section or sections so that the whole force available may be applied successively to separate sections of the row of hooks. In the form shown, the centre section 8 of the surface of the anvil 5 may be swung about a pivot 9 into the inoperative position shown. In operation, the press-head is first pressed down lightly while the section 8 is in operative position, so as to force the hook ends into the belt. The section 8 is then swung back as shown and the hooks near the edges of the belt pressed home by the full force of the press on the parts of the anvil. The section 8 is then swung into operative position and the centre hooks pressed home. The removable section may be slidable into or out of position.

Filed: 1973-01-10
Abstract: 1407113 Winch brakes A BRUSSELLE 10 Jan 1973 [12 Jan 1972] 1372/73 Heading B8B [Also in Division F2] A circular band brake for a rotary drum (e.g. a cable drum) 3 comprises a fixed support 1, a cylindrical rim 5 integral with the drum and a band 6 optionally provided with friction linings 7 passing around the rim; two connections are provided, one between end 8 of the band and the fixed support, and the other between the other end 19 of the band and the same fixed support; either of the connections between an end of the band and the fixed support can be selectively rendered inactive by a disengaging device, only one connection being active whilst the other is inactive. As shown in Fig. 1, a block 10 pivoted at 9 to end 8 is further pivoted at 15 to a piston-andcylinder device 11, 12, (the disengaging device) pivoted in turn at 13 to the support 1; the block 10 also supports a composite cylinder body 22, 26. End 19 is pivoted at 17 to a rod 16 having a slotted connection with a fixed pin 18 acting also as a pivot; end 19 is also pivoted at 24 to a traction rod 23 slidable in block 10 and acted upon by spring washers 21, or by pressure fluid above a connected piston 27. In one mode of operation, Fig. 1, pressure fluid is supplied beneath piston 11 so that it remains in the upper position shown. With pressure relieved above piston 27, springs 21 tighten the band by raising piston 27 and rod 23 while rod 16 slides freely on pin 18, leaving a clearance A. The degree of braking down to full release, may be controlled with high precision by admission of pressurized fluid above piston 27 because end 19, where the greatest tractive force occurs, is movable. In the second mode of operation, Fig. 3, pressure is relieved beneath piston 11, so rod 16 is able to slide down pin 18 and remain in its lowermost position while piston end 29 occupies an intermediate position in cylinder 12. With pressure relieved above piston 27, the brake now operates by downward pressure of springs 21 through the end of cylinder part 22, on (movable) end 8 while end 19 is fixed. In this mode the drum is effectively locked against rotation.

Class 70 Rubber articles such as inner tubes are spliced by gripping the end portions of the article, allowing a portion of the ends to project beyond the gripping means, severing the projecting portions close to the gripping means, increasing the gripping pressure on the article to cause the ends to squeeze partially out of the gripping means, moving the squeezed out surfaces into tight abutting relationship and releasing the gripping means. A preferred apparatus for splicing inner tubes comprises lower clamping jaws 1, and 2, Fig. 1, positioned in complimentary relationship with upper clamping jaws 3 and 4 respectively. Brackets 5 and 7 connect jaws 1 and 2 with fluid operating cylinders 6 and 8 respectively. Jaws 1 and 2 are moved in a horizontal path by means of* fluid operated cylinders 9 and 10 respectively.

Rotation of the spindle against a counterweight 57 is transmitted through reduction gearing to the wiper arm of a potentiometer, and rotation of the frame 54 is transmitted via step-up gearing to the wiper arm of a second potentiometer. The two potentiometers control voltmeters which are calibrated to indicate the deviation and the range of the golf ball. A magnet 58 retains the ball 50 in its rest position. The potentiometers may be replaced by magslip transmitters which are connected to magslip receivers (83, 84) (Fig. 5 not shown). The receivers operate a projector which throws a spot of light (simulating a.gilf ball) onto a screen, which includes a picture of a green; thus the position of the ball in relation to the flag is indicated.

Filed: 1922-01-24
Abstract: 196,671. Eyre, J. R. Jan. 24, 1922. Pressure regulating and reducing valves; fluidactuating mechanism.-In a pressure-reducing valve, steam acts on the opposed faces of a lift valve and leaky piston connected together, passes to the underside of the piston, and then upwards through the hollow spindle to a regulating throttle valve opening to the outlet side of the valve. The casing A is provided with a cylindrical chamber B carrying the seating for the valve E and enclosing the piston F. The hollow spindle D is guided in the projecting stem of the chamber B and in a projecting stem a from the cover A<1>, and its central bore d extends downwards to the openings d<1> below the piston. The piston is a slack fit in the cylinder, so that steam which passes through the openings b<4>, b<5> into the space B, may pass into the space G and thence through the bore d to the throttle valve H. The latter controls the passage of steam through the openings a<5> to the outlet side of the valve. A weighted throttle valve may be provided in a compartment J communicating with the bore d. A modification is described in which the throttle valve H is replaced by a rotary piston valve and an indicating quadrant moving over a fixed pin is provided. A thin flexible ring or washer may be arranged at the lower end of the chamber B so that a steamtight contact with the lower end of the piston may be obtained notwithstanding variable beat expansion. The valve opens by the pressure of steam which leaks into the space G, and remains open until the pressure on the outlet side of the valve balances the pressure in the space G, when the pressure on the larger area subjected to downward pressure closes the valve. The pressure on the outlet side of the valve then falls and the valve opens again. When the relief valve is employed, a constant pressure is maintained under the piston, and a constant reduced pressure is obtained independently of variations of the generator pressure.
