Abstract: 813,895. Shelling groundnuts. COMPAGNIE FRANCAISE DE L'AFRIQUE OCCIDENTALE. Oct. 15, 1957 [April 6, 1957], No. 32133/57. Class 58. A machine for shelling groundnuts comprises a hopper a having at the bottom a flat grating d, e.g. in the form of a perforated sheet of steel or steel rods. Two bars e pass slidingly through openings w in the ends of the hopper and carry, close to the grating, a beater. The ends of the bars are joined by rods j passing through wooden handles i. The beater can be adjusted to vary the clearance between it and the grating and comprises two plates m, each of which is adjustably secured to a bar e by bolts r passing throughelongated openings m<SP>1</SP> in the plate. The two plates are joined by transverse beater bars g,  which may be angle-sectioned and pointing towards the grating, as shown, cylindrical, or square rods passing through square openings each having a vertical diagonal so that an edge of each rod points towards the grating and the rods can be removed from their openings, turned through a right-angle and replaced to present another edge to the grating. Replaceable angle plates k are attached to the ends of the hopper above and below the openings w to prevent wear at their lower and upper edges. To-andfro movement of the bars e is limited by providing them with stops s which cooperate with spring buffers h on the hopper. Groundnuts are  fed into the hopper. The latter is supported on four legs b braced by struts b<SP>1</SP> and cross-braces b<SP>2</SP>. The machine is operated by two people, one at each end, who grip the handles i and give to-and-fro movement to the bars e and the beater. The nuts are shelled as they are rubbed and jolted between the lower face of the beater and the grating. Kernels and broken shells fall through the grating and are separated by blowing with air.

Title: Improvements in tubulous vapour generating and vapour heating units
Inventor: HUTCHINGS EDWARD GEORGE
IPC: F22B21/08
Filed: 1952-12-23
Abstract: 737,200. Water-tube steam boilers; steam superheaters. BABCOCK & WILCOX, Ltd. Dec. 18, 1953 [Dec. 23, 1952], No. 32676/52. Classes 123 (2) and 123 (3). A water-tube steam &c. boiler especially for marine use has two furnace chambers 1, 3 lined with refractory covered steam generating tubes and fired respectively by burner groups 8, 12 through ports 7, 9 in the front wall of the unit, the gases from furnace 1 discharging laterally through a screen 47 of generating tubes into parallel gas passes 13, 15 separated by a passage. way 17 and leading to a common uptake 19 in which is disposed an economizer 20. The gas flow through each pass 13, 15 is controlled by dampers 21 at their respective outlets into uptake 19. The passes 13, 15 locate respectively the sections 25 and 27 of a convection steam generating tube bank 23, the tubes of which extend between a water drum 31 and a steam and water drum 29, the latter also receiving the output from the furnace lining tubes which extend from lower headers 75 and 115. Between the screen 47 and the tube bank 25, pass 13 locates a superheater 33. The gases from furnace 3 also discharge laterally through a screen 60 behind which is disposed a reheater 53, the gases, after traversing the reheater, flowing through passageway 17 into a turning space 151 which serves to direct them into pass 15 and thence to uptake 19. During normal operation, both furnaces are fired, the steam output and reheat temperature being respectively regulated by adjustment of the firing rate of burners 8, 12 whilst the superheat temperature is regulated by control of dampers 21. During manoeuvring, furnace 1 is worked to give a substantial output of steam with little or no superheat whilst furnace 3 and reheater 53 are inoperative, the safety of the reheater being ensured since it is screened from furnace 1 and is not subjected to gas flow. During starting, furnace 1 only is fired, dampers 21 of pass 13 being closed to prevent damage to the superheater. In modified forms of the unit (Figs. 5-9, not shown) furnaces 1 and 3 are disposed side by side, the gases from furnace 3 flowing into furnace 1 after passing through a screened reheater.

Title: Data signalling system
IPC: G11B20/14
Filed: 1966-07-21
Abstract: 1,122,342. Digital data-storage. INTERNATIONAL BUSINESS MACHINES CORP. 21 July, 1966 [27 July, 1965], No. 32708/66. Heading G4C. Data bits are each represented by the presence of a clock pulse and the presence or absence of a data pulse during a clock interval, and format signals, such as signals indicating the start or finish of a data word, are each represented by the presence of a data pulse and the absence of a clock pulse during a clock interval. In a first embodiment, such signals from a magnetic store are fed to a variable frequency oscillator (twice the clock frequency) and two AND gates. The oscillator controls a trigger, the true and complement outputs of which enable the two AND gates respectively, to gate out data and clock pulses on to respective lines. The absence of two (in view of the possibility of drop-out) consecutive clock pulses, indicating word end, is detected by a ramp generator (normally reset by the clock pulses) feeding a threshold device. In a second embodiment, the oscillator and trigger are replaced primarily by a delay and single-shot. In this case, word end is indicated by the following read from the store in sequence: clock pulse absent, data pulse present, clock pulse present, data pulse absent. As a result, two consecutive intervals between pulses on the clock pulse line are <SP>3</SP>/ 2  the normal length, to indicate word end.

Title: Improvements in railway vehicles having automatic couplers and release mechanism therefor
Inventor: HOLLIS RICHARD JOHN
IPC: B61G3/20
Filed: 1959-09-25
Abstract: 952,058. Railway vehicle automatic couplings and draw gear. DOWTY HYDRAULIC UNITS Ltd. Sept. 8, 1960 [Sept. 25, 1959; Nov. 11, 1959], Nos. 32729/59 and 38297/59. Heading B7T. A railway vehicle having an automatic coupler slidably mounted thereon for movement in the longitudinal direction of the vehicle, and release mechanism for operating a movable coupler release member on the coupler, wherein the release mechanism comprises a release lever supported on the vehicle behind the coupler and a mechanical connection provided between the coupler and the release lever, the mechanical connection having a pivotal attachment to the release lever forming a fulcrum about which the lever can turn, and which fulcrum, by means of the mechanical connection, is longitudinally movable with the coupler, and a connecting element extending backwardly from the movable coupler release member to a point on the release lever which is spaced from the lever fulcrum. The coupler head 12 which engages by inclined swing is supported from the railway vehicle for longitudinal movement with respect thereto by a draw spring 29, and by a spring 48 which may be compressed on buff or draw by movement of either of the telescopic members 43 or 46 within a fixed cylinder 42, the head being provided with a ball- and-socket 25 and a restoring torsion spring 33 bonded to a pin 23 and a pivoted cup 32. A spring-loaded catch 17 which is adapted to lock the latch 13 of a mating coupler may be disengaged by movement of a lever 21 connected by a chain 22 to a point on the release lever 55. The lever 55 is mounted on the vehicle and guided along a strip 58 by a strap 59, and may fulcrum about either of the points 63 or 66 which are connected by chains 61, 64 to a plate 52 bolted to a rod 36 attached to the cup 32. Swinging of the lever 55 about either the point 63 or the point 66 therefore tensions either the chain 61 or the chain 64, and exerts a pull on the chain 22 to operate the catch 17. The release mechanism operates independently of the sliding movement of the drawbar 26 because inward movement of the head 12 and bar 26 causes the rod 36 and the plate 52 to move inwardly an equal amount so that no pull is applied to the chain 22. Similarly, pivotable movement of the head will not alter the effective length of the chain 22, so that the latch 17 will remain locked unless the lever 55 is swung.
