The radome 12, which may be moved between the stowed position within the recess 11 and an extended operational position clear of the exterior surface, is connected by a member 13 to a transmitter/receiver 14 which is guided within four guide tracks 15 supported by a support structure 22. The transmitter/receiver 14 includes a motor (not shown) for rotating the radome 12, and is supported by a threaded shaft 17 universally jointed to its upper surface and engaging with a rotating nut in an actuator 18. Rollers 23 at each corner of the transmitter/receiver 14 engage the guide tracks 15, the upper ends of which are attached to the legs of a spider 16 at the centre of which is located the actuator 18. An hydraulic motor 24 is secured to the actuator casing and is connected via reduction gearing to the nut within the casing which engages with the threaded shaft 17. The motor within the transmitter/receiver 14 for rotating the radome 12 is automatically isolated except when the radome is in the fully extended operational position or a predetermined intermediate position during retraction when the radome is incorrectly aligned with the recess, and alignment means are incorporated so that the radome is automatically aligned with the recess before retraction can be completed. The alignment means includes a microswitch carrier 32 located around the connecting member 13 and slidable vertically on guides 38 extending upwardly from a fixed structure 33. In the fully extended position, the carrier 32 rests on the structure 33 with the microswitches 34, 35 clear of a camming surface 36 but on raising the member 13 (and radome 12) a distance F, the microswitches are depressed by the camming surface 36 and before any further retraction of the radome 12 occurs, it is rotated until in alignment with the recess 11 when the microswitches are released by dropping into recesses in the camming surface 36. On further retracting the radome 12, the camming surface 36 engages projections on the carrier 32 which then rides up the guides 38 with the microswitches 34, 35 within the recesses in the camming surface 36.

Abstract: 1,176,889. Semi-conductor arrangement. INTERNATIONAL BUSINESS MACHINES CORP. 23 Jan., 1968 [14 Feb., 1967], No. 3382/68. Heading H1K. [Also in Division C6] A pattern of conductivity is formed on an amorphous substrate by transforming selected portions on the surface thereof into crystalline form and electro-plating a conductive material on to said portions. The amorphous substrate may be of semi-conductor material, e.g. germanium or silicon, and may be doped. The selected portions may be transformed into crystalline form by heating said portions, e.g. with a laser beam or an electron beam. The plating may be carried out electrolytically, e.g. copper or silver may be electroplated on to a germanium substrate from cyanide baths. A doped amorphous substrate may be formed on a base material, e.g. of quartz, by vapour deposition of substrate and dopant from separate sources using rate monitoring devices to maintain the proper ratio between the two evaporations, or by using a doped starting material of such composition to give the required deposit (this will not be an identical composition).

Abstract: 524,606. Actuating controllers. WEST & CO., Ltd., A., and PADDOCK, W. J. Feb. 2, 1939, No. 3516. [Class 38 (iii)] A drum controller 1 is moved in its accelerating direction by means of a pneumatic motor 3 having a piston 5 operating through a rack 7 and pinion 8. Control of fluid pressure to the motor 3 is effected by a valve 10 controlled by contacts 14, 15, carried respectively by a handle 2 and the controller 1, the valve being operated to stop the motor 3 when the controller 1 has followed movement of the handle 2. Movement in the reverse direction to braking-positions through the neutral position shown is effected by the engagement of a lug 19 on the handle 2 with a lug 20 on the control drum. The movement of the drum 1 in the accelerating direction is controlled by a piston 21 forcing liquid through a valve 26 which is closed to arrest motion upon overload conditions by the energization of a coil 30. Liquid returns to the cylinder 22 freely through a valve 31 and the connection between the rack 7 and the piston 21 permits movement of the controller to its braking positions after the piston has returned to its end position under fhe influence of a spring 32.

Title: Bowling pin spotting and respotting mechanism
IPC: A63D5/08
Filed: 1957-02-01
Abstract: 820,655. Skittle alleys. TRIGGS, W. W. (American Machine & Foundry Co.). Feb. 1, 1957; No. 3534/57. Class 132(2) In a skittle alley in which spotting and respotting of skittles is effected by vertical reciprocation above the alley bed of a table 312 carrying an array of spotting and re-spotting units the spotting units have cups 330 movable 'on the table and releasable from the pins by downward movement relative to the axis of the standing pins on the alley bed as the table approaches a lowermost position. The cup 330 normally occupiesthe position shown in Fig. 10 and holds a pin 11 which is prevented' from slipping out by a half ring 336. To spot the pin, the table is lowered and the cup is swung to the position shown in Fig. 7; then* as the table continues down the pin contacts the alley bed and the cup moves down relatively to the pin in the direction of arrow E to free half ring 336 from the pin. The cup is then swung further back to the dotted position of Fig. 7, the table and cups are raised clear of the pins, and the cups are returned to the position of Fig. 10 to receive a fresh set of pins. The machine operates on the following cycle. Dead pins are lifted from the rear pit of the alley by a rotating conveyer wheel which supplies them to an endless telescopic conveyer carrying them te the table. The front end of the conveyer moves up and down with the table and is caused to move from spotting cup to spotting cup to deposit a pin in each. By a first push button, the machine makes one cycle to spot a set of pins from the cups as described above. If the first ball knocks all pins down, the alley bed is swept clear and the first push button is operated to spot a new set of pins. If the first ball leaves some pins standing a second push button is operated, which prevents swing- ing of the cups 330 to spotting position but allows descent of the table As the latter descends a pad 388 contacts a standing pin and is thus arrested side grippers 376 however continue to descend and by cams 366 move in to grip the pin and are locked in this position. They automatically centre themselves to an off-spot pin. The table then rises to lift the standing pins and dead pins are swept from the alley bed. The table then descends to respot the standing .pins, the side grippers 376 are unlocked, and the table rises again. After the second ball, the alley bed is swept clear and, by operation of the first push button, a new set of pins is spotted. The level and position of the table can be adjusted. If the descending table foul an obstruction, the driving motors are automatically stopped. U.S.A. Specifications 2,767,983 and 2,767,984 are referred to.

Abstract: 1,047,084. Preserving and shelling crustaceans. MASCHINENFABRIK BUCKAU R. WOLF A.G. Jan. 30, 1964 [Feb. 1, 1963; Aug. 23, 1963], No. 4028/64. Headings A2D and A2U. In preserving and shelling crustaceans, such as shrimps and prawns, freshly caught crustaceans are boiled in water or a desired aqueous liquid and cooled, in air and then in a refrigerator, to a temperature between 1 aid 4‹C. They are then freeze-dried and their shells are mechanically broken up and detached from the meats, as by feeding the freeze-dried crustaceans through the nip between two elastic, resilient and gripping surfaces, one of which moves relatively to the other, which is preferably stationary. Suitable shelling apparatus comprises a roller 1, rotating in the direction indicated by the arrow A, curved with an elastic, resilient covering 3, e.g. of profiled rubber having an underlying base of foamed material, a concentric curved fixed plate 2 covered with elastic and resilient coverings 4 and 5, of which covering 4 is harder than covering 5, a perforated delivery screen 7 and a centrifuging roller 10 rotating rapidly in the opposite direction to the roller 1. The freeze-dried crustaceans are fed, by an endless conveyer belt 8, along a shoot 9 into a narrowing, wedge-like passage 6 between the coverings 3 and 4. As the crustaceans are carried through the nip between coverings 3 and 4 and 3 and 5, their heads and tails are torn off, and their shells are torn open, detached from the meat and broken up. The resulting mixture of meats and broken shells then passes over the screen 7, through which most of the broken shells pass into a receptacle 14. The meats and remaining pieces of shell fall on to the roller 10, which flings meats into a receptacle 12 and pieces of shell into a receptacle 13. A suction device 15 may be provided, over the screen 7, to remove lighter pieces of shell. Alternatively a blower may be provided near the screen 7, to blow or winnow away the lighter pieces of shell. The whole apparatus may operate in a protective gas, such as nitrogen or carbon dioxide in a surrounding chamber.
