Title: Improvements in and relating to cargo derricks
IPC: B66C23/60
Filed: 1938-11-22
Abstract: 525,545. Ships' derricks. MACFARLANE, L. K., (Representative of MACFARLANE, G. T.). Nov. 22, 1938, No. 33943. [Class 78 (iv)] The load rope 6 passes over a speciallymounted pulley 8 at the boom head, over a pulley 10 on the mast and then down to a winding-drum 11. By engaging the hook 7 to the eye 14, the hoisting rope can be used to luff the boom, which is then secured in position by winding the rope 4 round the cleat 5. To mount the pulley 8, a bifurcated bracket 18, Fig. 2, is formed with an integral socket 16 fitting over the end of the boom. The pulley 8 is carried by a bracket 19 which can move in the plane of the boom about the trunnions 20 and also move perpendicularly to this direction about the bearings 37. 41. The rear end of the bracket 19 is guided slidably between the bifurcations of the bracket 18, and carries a thimble guide 42 for the rope, and in some cases also a pair of rope-guiding pulleys 47. Wearing-pieces 22 are fitted to the bracket 18 so that they can be replaced as necessary. The securing rope 4 is attached to the bracket 18 which may also carry lugs for attachment of guy ropes. In a modified construction the pulley 8 is carried by a bracket fitted with a U-shaped swivelling hook engaging a second U-shaped hook fixed to the outer end of the bracket 18.

Title: Improvements in or relating to portable power-driven machines for setting-up nuts, screws and the like
IPC: B23B45/00
Filed: 1929-11-11
Abstract: 336,132. Chicago Pneumatic Tool Co., (Assiguees of Meunier, L. F.). Nov. 12, 1928, [Convention date]. Bolts, nuts and screws, assembling, screwing-up, and unscrewing. - In a portable machine having a yielding clutch for screwing up nuts, screws, studs, &c., the driving shaft B has connected thereto or formed integral therewith a clutch part 3 normally maintained out of contact with a co-operating part 9 by a spring 11 acting through a centre point 11a. The part 9 is rotatably secured to a hollow tool shaft 8 by means of balls 10 and is provided with a second set of teeth 9b co-operating with teeth 7b on a sleeve 7 which is slidably keyed to the shaft 8 by balls 78. A spring 12 abuts against an adjustable nut 13 screwing on the shaft 8 and normally maintains the clutch teeth 7b, 9b in engagement. In operation, axial pressure of the screw-driver, nut socket, &c., on the shaft 8 engages the clutch 3, 9, whose teeth are large, whereas the teeth 7b, 9b are smaller so as to disengage when the nut, &c., becomes set. The teeth 7b, 9b preferably engage only once or twice per revolution. The spring 12 lies almost entirely within a recess 7c in the sleeve 7 and the latter is entirely supported by a casing 6 secured to the main casing A by bolts 5, the shaft 8 being thus supported entirely by the clutch members 7, 9. A flange 7a prevents excessive downward movement of the sleeve 7. The shaft B is rotated through reduction gearing, (not shown) from an electric or fluid pressure motor forming a part of the machine.

Title: Manually operable brake valves
IPC: B60T15/04
Filed: 1973-07-20
Abstract: 1434553 Drivers' valves ROBERT BOSCH GmbH 20 July 1973 [24 July 1972] 34727/73 Heading F2F An inlet valve is influenced by a manually operable lever and is responsive to and adapted to be closed by fluid pressure downstream thereof attaining a predetermined value thus retaining this downstream value irrespective of fluctuations in upstream pressure, the lever upon movement into a given brake application position opens an exhaust valve, the inlet valve operating as above when the lever is not in this position. With the lever 16 in the position shown (not the application position), pneumatic fluid enters an inlet 30, passes along the outside of a hollow stem 5 and through the inlet valve comprising a shoulder 23 on the stem and a seal 24 until pressure acting on the stem overcomes the force of a spring 6 of the valve to close the inlet valve thus limiting the downstream pressure at an outlet 33, when the lever 16 is moved rightwardly to a second position, a plunger 11 is forced down by an eccentric cam 15 to move a plate 9 to remove the spring force from the stem 5. Furthermore the exhaust valve, constituted by a plate 13 and a shoulder 20, is opened to exhaust pressure at the outlet 33 to atmosphere via passages 22, 21, 38. The pressure responsive areas of a piston end 27 of the stem 5 and of the annulus of the seal 24 are equal so that the freely floating stem 5 is not moved by inlet pressure fluctuations. With the downstream pressure at atmospheric pressure, a spring 19 retains the inlet valve closed.

Abstract: 1340306 Semi-conductor devices WESTERN ELECTRIC CO Inc 27 July 1972 [2 Aug 1971] 35131/72 Heading H1K A method of making an IC containing two transistors comprises forming a common collector region on a substrate, forming at a first area a high resistivity base region for one transistor, masking the centre of this high resistivity region, forming around the mask a more heavily doped base contact region and simultaneously forming a base region for the second transistor at a second area of the collector region, and forming emitter regions for the two transistors. The first device is a high-gain high-frequency transistor and the second device is a conventional planar transistor. As shown, Fig. 3, a P type Si substrate 11 is provided with two N<SP>+</SP> type subcollector regions 15, 16 and a N type epitaxial layer 18 is deposited to form the collector regions of the transistors. The surface is masked and a high resistivity P- type base region 21 for the high gain transistor is produced by implantation of boron ions followed by redistribution using a boron cap to prevent out diffusion. The centre part of the base region 21 is masked and a window is etched over the subcollector region 16, and impurities are diffused-in to form P<SP>+</SP> type base contact region 26 and base region 25. The surface is then remasked and N<SP>+</SP> type emitter regions 29, 30 are formed by diffusion. Base contact windows are opened and emitter and base contacts are formed. In the high frequency transistor the active portion of the emitter is restricted by the base contact regions to the small area in contact with the high resistivity base layer 21. In a modification, Fig. 5 (not shown), the active part of the base region of the high resistivity transistor is divided into two stripes by appropriate shaping of the base contact region, and an N<SP>+</SP> type collector contact region is formed in the top surface of the layer.

Abstract: 383,456. Fountain pens. REICHENBACH, G., 7, Kaiser-Friedrichstrasse, Pforzheim, Germany. Dec. 18, 1931, No. 35133. [Class 146 (iii).] In a fountain pen of the type in which the reservoir a, nib c, and feed-bar are slidable in an outer casing e provided with a hinged lid m which opens to permit the passage of the nib to writing- position, the relative movements of the reservoir and casing are limited by a stop h<2> formed as a ring and inserted into the casing. The reservoir is guided in the casing by a projection f on the reservoir moving in a groove g, and the engagement of the pro-, jection f with the ring h<2> limits the inward movement of the reservoir, the forward movement being stopped by the engagement with the ring of the end of the handle d on the reservoir. The bore of the casing is of larger diameter at the rear end than at the front end and the position of the ring h<2>, which is secured in place by rivets, is determined by the shoulder between the bores. The groove g extends throughout the length of the front end of the casing and is closed at the rear end by the ring h2.

[Class 97 (i)] A light-dividing system for obtaining a number of exposures simultaneously from the same point of view through a number of separate lenses, comprises transmitting reflectors for directing the light to the several lenses and refracting compensator plates to correct or equalize distortion caused by the refraction of the light transmitted by the reflectors. The arrangement shown for obtaining simultaneous exposures in three kinematograph cameras 3 which can be simultaneously operated by a handle 9, comprises parallel transparent reflectors 10, the first of which reflects part of the light to the first camera and transmits part to the second reflector which similarly divides the light between the second and third cameras. The third reflector 10 may be a mirror. The light reaching the second camera has been refracted by the first reflector and that reaching the third camera has undergone refraction by the first two reflectors. To compensate the distortion due to these refractions parallel transparent plates 11 are used, two of these being inserted in the light path to the first camera and one in the path to the second, so that all the rays undergo two refractions.
