Title: A machine for picking up vegetation from the ground
IPC: A01D89/00
Filed: 1952-10-09
Abstract: 713,302. Picking up loose vegetation. JACOBSEN, J. A., and JACOBSEN, E. J., [trading as BRODRENE JACOBSEN.] Oct. 9, 1952 [Oct. 16, 1951], No 25368/52. Class 6 (3). [Also in Group XXX] A pick-up loader, of the type having a pickup cylinder comprising a multi-section drum 6 with prongs 9 protruding through the spaces 8 between adjacent sections, the prongs being mounted on an eccentric shaft 7 within the drum, is characterized in that the drum and shaft are driven at the same speed from a common source but by independent driving means. The machine includes a wheeled frame 1 carrying an endless elevator 17 which lifts the pickedup crop to a point above a trailer (not shown) attached to the hitch 20. The frame 1 is drawn by a tractor which drives a cross-shaft 12 through bevel gearing 15. Sprockets 13, 14, and chains 10, 11 transmit the drives to the drum and shaft respectively. The drum (Fig. 4) comprises endwalls rotatably mounted in bearings 32 on the frame 1 and interconnected by tubular transverse shafts 23 to which arcuate drum-sections 6a, 6b, 6c are bolted, the sections being stiffened by internal webs 26. The shaft 7 carries spaced triangular plates 37 from which bars 38 extend equi-angularly. The bars carry the prongs 9 which have resilient mountings comprising helical or spiral coils 42. The prongs retract completely into the interior of the drum at the point where the pick-up cylinder passes its load to the elevator 17.

Title: Apparatus For Use In Error Detection Systems
Inventor: COOK HAROLD DALE
IPC: H04L1/24
Filed: 1966-06-09
Abstract: 1,152,412. Parity check signal generator. TELETYPE CORP. 9 June, 1966 [6 July, 1965], No. 25704/66. Heading G4A. [Also in Division H3] Apparatus for generating a parity check signal comprises means for generating a simple parity signal, means responsive to the parity signal and to each element of the input signal to produce a plurality of bits, each of which corresponds to a different one of the elements of the input signal, and means responsive to said control signals to produce said parity check signals. Input signals from a data source are passed by AND gates 29a-29h to two sets of EXCLUSIVE OR gates 31-33 and 30a-30h. The gates 31a-31d, 32a, 32b and 33 generate a simple parity bit, producing a " 1 " if an odd number of " 1's " exist in the input signal, and a " 0 " otherwise. The simple parity bit or vertical parity bit signal is passed as one signal to gates 30a-30h the other signal of which is supplied by the corresponding output of the gates 29a-29h. The output of gates 30a-30h is passed to bi-stable devices 38a-38h respectively, which form a shift register to produce a spiral parity check bit. The bi-stable devices have trigger inputs F.E.C.D., priming inputs H.J.M.N., one of which must be supplied with a " 1 " for its corresponding trigger input to change the state of the bi-stable device if a " 1 " is supplied thereto and outputs K, L, K, for a " 0 " storage and L for a " 1." Thus a signal from the corresponding gate 30a-30h will change the state of the bistable devices 38a-38h since the appropriate priming inputs are cross-coupled to the outputs of the same stage. A shift signal applied to terminal 39 causes the contents of the bistable devices to be shifted right as shown in Fig. 3, and for the spiral parity check to emerge from the PARITY BIT OUT terminal.

Title: Improvements in gate catches
IPC: G02B6/44
Filed: 1922-09-22
Abstract: 206,976. Winfield, A. T. Sept. 22, 1922. Catches, automatic.-A gate is secured by a gravity catch directly pivoted on the gate or gate - post at right-angles to the plan of the gate, and has a slot between two projecting parts of unequal length, the shorter one having a cam-face, for coacting with a fixed pin on the gate-post or gate. The catch a is pivoted at b and has a slot k working over a pin j to limit its movement. When the gate is closed, a pin rides along the cam-face f of the shorter projecting part, lifting the catch, until the pin enters the opening h, when the catch drops by gravity to secure the gate. A part i on the longer projecting part g, forms a stop to prevent the catch rising too high when the gate is slammed. The opening h has a constricted neck p and a backwardly sloping side q which prevent the latch from being forced upwards on recoil of the gate after being slammed. The catch is released by handles d, e.

Abstract: 843,858. Valve oscillators. GENERAL ELECTRIC CO. Ltd. May 14, 1958 [Aug. 14, 1957], No. 25708/57. Class 40(6). An oscillator of the Colpitts type for use at high frequency and high power has the anode-earth capacitance shunted by a low impedance, the cathode being effectively isolated from earth at the operating frequency by a cathode choke. As shown the tuned circuit of a Colpitts type oscillator is formed by an inductive impedance constituted by the series combination of the inductance 9 and capacitor 12, and a capacitive impedance formed by the inter-electrode capacitances of the valve Cga, Cgk, Cak the capacitive impedance of the chokes 5, which are tuned above resonance, and the capacitor 11. The oscillator is contained in a screened box 2 which is earthed and the anode is connected to the box by a short lead. In an alternative embodiment described with reference to the Figure accompanying the Provisional Specification (not shown) the capacitor 12 is omitted.

Filed: 1953-09-21
Abstract: <PICT:0742207/IV(c)/1> <PICT:0742207/IV(c)/2> <PICT:0742207/IV(c)/3> Figs. 1 and 2 show an apparatus for printing piece goods comprising a pigment padder P, and washer W of conventional design and an ager A. The fabric F after padding at P with a solution containing a reducing agent is passed for a period of 5-30 seconds into the ager A which contains an atmosphere of wet steam, free from oxygen at a temperature of 212 DEG F-220 DEG F.  The entrance to the ager is heated by steam pipes 16, 20 to prevent condensate from dripping on to the fabric which passes over guide roller 22 and driven conveyer rolls 10 and finally out into washer W.  The fabric F is supported on the unprinted side only thus preventing the running of colours and condensation from the walls of the ager chamber 5 is prevented by heating with steam pipes or coils 32, 48.  Mounted above the floor is a perforated baffle 34 through which runs a steam pipe 36.  Any condensate is discharged through funnels 40, 41 and the ager is insulated by lagging 52 the steam pressure in the chamber prevents the entrance of air from outside. In a modification Figs. 3 and 4 (not shown) the ager chamber is supported from the ceiling is slightly arcuate and has a flat perforated baffle supported from its floor.  The fabric after passing from the padder ascends vertically through an insulated steam heated conduit into the ager and descends vertically through a similar conduit on the exit side of the ager before passing into the washer.  In a further modification Fig. 5 (not shown) the padder is located at a higher level than the washer and the ager approximates in shape to an inverted J the steam distributer comprising a series of transversely extending perforated pipes each provided with a semi-circular baffle.  In a modification shown in Fig. 6 the fabric path through the ager may be changed thus permitting different periods of exposure whilst allowing the same rate of travel.  The ager is of inverted U-shape and steam is blown in from steam pipes 95 cooperating with perforated cylindrical baffles 96.  The fabric F may take any of three different paths viz. over guide rollers 10a, 10b, 10c or 10a, 10d, 10e, 10c or 10a, 10f, 10h, 10i, 10j, 10k, 10g, 10c.

Abstract: 648,566. Warp stop motions. ELECTRICAL PRODUCTS (COLNE), Ltd., and PEARSON, E. Oct. 7, 1948, No. 26111. [Classes 142(i) and 142(iv)] A warp stop motion comprises a pivoted thread guide which drops, upon thread breakage, and moves a U-shaped lever whereby an electric circuit is closed and the machine stopped. Thread guides 12 are clipped on to a rod 14 mounted in a slotted grid 13 which positions the guides and which is attached to a frame 10. When a guide drops, upon thread breakage, its lower end rocks a U-shaped lever 15 so that an insulated projection on the end of a shaft 15a, to which the lever 15 is secured, closes two spring contacts and the machine is stopped. A tell-tale lamp may be lit when the machine stops. The threads pass over a rod 22 carried by rods 24 pivoted to the frame 10 and, to facilitate threading of the guides, the rod 22 may be swung downwards when a rod 26, also carried by the rods 24, brings the guides to an approximate vertical position. Any guides not required may be unclipped from the rod 14 or engaged behind a U-shaped pivoted arm 27. A stop 20 prevents the levers 15 from dropping too low and out of range of the lower ends of the guides.
