Title: Mobile crane
IPC: B66C23/36
Filed: 1965-04-21
Abstract: 1,096,078. Folding mobile jib-cranes. H. BROZIAT. April 21, 1965 [April 27, 1964], No. 16903/65. Heading B8B. A crane jib 12a, 12b is luffed by a cable 18 which passes to a winch on a trolley 19. The latter is driven round a fixed ring 4 by a sprocket and chain to slew the jib which is supported by a ring 10. Counterweights 32 are attached to the trolley. The hoisting rope 14 passes through a hollow pillar 7 to a fixed winch 17. The jib 12a is longer than the pillar 7 so that loads may be lifted with the crane folded down and a load hook 13 may be engaged with a ring 28a. To prevent damage during folding rollers 30a, 30b are provided. Relative movement between the chassis and the axles is prevented by telescopic members which are attached one to each structure and are pinned together when the crane is working. Fig. 6 (not shown), illustrates a latch 41 which holds the pillar 7 erected. As the pillar reaches a vertical position a bell-crank 56 abuts a stop 43 and a pin 44 moves out of a recess 58 so that the latch 41 may be urged downwards by a spring 45. The latch is raised by a pneumatically lifted piston 60 controlled by a magnetic valve. An electrical interlock is provided to prevent the latch being raised until the crane is under the control of the hoisting cable with the hook engaged in the ring 28a.

IPC: F41A25/02
Filed: 1916-11-27
Abstract: 127,281. Schneider et Cie. July 12, 1916, [Convention date]. Recoil apparatus.-Relates to hydraulic recoil apparatus having means for modifying the length of recoil according to the elevation of the gun, and comprises the combination of two brakes working with entirely separate bodies of liquid, one furnishing almost the whole of the braking-force for long recoils, and the other acting for short recoils. The two brakes may be arranged side by side but, in the preferred form, are concentric, as shown. The longrecoil brake is of usual form, comprising a piston A<1> and hollow piston-rod A<2> attached to a support D on the recoiling slide E of the gun, and a cylinder A secured to the cradle B, to which is also connected the rod A<3> for regulating the run-out. The short-recoil brake is arranged between the cylinder A and the walls of a jacket F provided under the slide E, the cylinder A being enlarged at one end as at F' and constituting the piston of the second brake device, while the cylinder F constitutes the recoiling part attached to the gun. Ports f<1>, Figs. 1 and 5, are arranged in the piston head F' and, for long recoils, are. open so as to render the brake inoperative. For short recoils, the ports f<1> are closed by a fixed partition G, with ports g, in relation to which the piston member is automatically rotated as the gun is elevated. Tapered keys F<3> engage slots in the top and bottom of the member G, F<1> and prevent rotation of the member G, whilst permitting limited rotation of the member F'. For the purpose of this adjustment, the combined pistoncylinder member A is rotatably mounted in the cradle B, and is rocked on its axis through gear segments H, I, Fig. 2, by means of a rock lever L and sliding rod M, the end of which is formed with a pin and roller M<1> engaging a fixed campath N, the pin passing along the cam-path as the gun is elevated.

Abstract: 1,067,774. Selecting cards. F. FREIDL. April 24, 1964, No. 17202/64. Heading G4M. A stack of cards 17 is held in a container movable on rails 31, 32 by means of ballbearings 30, a selecting needle holder is similarly mounted on rails 33, 34 and is slidable over the card container so that the needles pass through the stack 17 and interspersed lattice plates 38. The stack 17 with the needles therethrough is pushed past a separating station comprising an endless belt 40, 41 which is driven faster than the stack 17 and serves to separate the cards, while an electromagnetic vibrator 43 causes the selected cards to be partially ejected from the stack. Each card has a lattice of pre-punched holes forming rows and columns, and data holes are formed by enlargement of selected lattice holes in the row or column direction. The enlargement may be such as to merely enlarge a lattice hole without affecting surrounding holes, or it may join two adjacent lattice holes, or it may completely obliterate a lattice hole. The enlarged holes are stated to be compatible with automatic sensing arrangements such as contact brushes, Fig. 4 (not shown).

Title: An improved log-barking machine
IPC: B27L1/04
Filed: 1958-06-02
Abstract: 849,149. Removing bark from logs. SEARLE, R. W. June 2, 1958 [June 7, 1957], No. 17559/58. Class 145. A log-barking machine has a rotatable cutting head 9 with a pair of universallypivoted arms 10 which carry rotating planing cutters 11 and the arms are pressed towards the log by a spring 50 adjustable by a lever 49. A freely-rotatable circular knife 35 or spiked  wheel is fitted on one side of each cutter and a plain disc 37 on the other side, the knife 35 penetrating through the bark and the disc 37 contacting the stripped log behind the cutter to control the depth of cut. A motor 52 drives the cutting head 9 through a chain drive 53 to a sprocket 54 and the arms 10 are mounted on universal joints on housings 12 carried by the head, a small wheel 51 on each arm limiting the movement of the arm towards the head. The cutters 11 may be driven by individual motors on the arm, either by a chain drive or by mounting the cutting blades 28 on an external rotating member of the rotor or a chain 56 passed loosley around a stationary sprocket 57 may engage a sprocket 22 on a shaft 19 in each housing 12 to form a planetary gearing driving each cutter at a high speed through a universal joint and a chain drive 34. The arms are connected by linkage 44 to spindles 39 having torsion springs 46 which tend to move the arms for withdrawal of the cutters from the log but pulleys 43 on cranks 41 on the spindles are connected by a double loop of cable 47 to the spring 50 so that, by means of the lever 49, the force of the springs 46 can be overcome to an extent according to the hardness of the wood of the log. Alternatively, springs may be connected between the arms and brackets on the cutting head. Two opposed pairs 3, 4 of double-cone feed rollers are provided on each side of the cutting head and are driven by chain drives from a second motor, the forward rollers 3 rotating faster than the withdrawal rollers 4 so as to enable logs to be fed continuously despite any slight delay in the introduction of successive logs. The rollers are moved towards the log by linkage 60 and springs 66 but each end pair of rollers can be moved apart by a foot lever 63. The forward rollers have longitudinal ribs and the withdrawal rollers have spikes.

Abstract: 1,168,219. Semi-conductor device. S. TESZNER. 11 April, 1968 [11 April, 1967], No. 17656/68. Heading H1K. A semi-conductor field effect device has two constricted regions 46 and 48 in its channel between the source 45 and the drain 49, both channel regions having smaller cross-sectional area than the channel portion at the gate 47. The constricted region 46 is shorter than the diffusion length of the minority carriers and long enough for the electric field in it to be less than the critical field value at which the carrier mobility decreases with increasing field so that the current-voltage characteristic, Fig. 5, not shown, is linear. In a further embodiment, Fig. 11, not shown, the constricted region (66) is much shorter, so that the electric field in it is greater than the critical field value at which the carrier velocity is constant, corresponding to a saturation current-voltage characteristic, Fig. 6, not shown. The device is made of silicon, germanium, or a Group III-V compound, and being bi-stable is suitable for use in a flip-flop circuit. In a further embodiment, Fig. 18, not shown, the channel is perpendicular to the major surface of the semi-conductor wafer and the constrictions (90) are formed by doped regions (86, 87) buried in the wafer.
