Filed: 1938-11-29
Abstract: 509,119. Separating solid materials. BEAULAH, W., and OSBORNE, R. G. Nov. 29, 1938, No. 34797. [Class 117] A machine for sorting dried peas, comprises a roller with a burred or toothed surface rotatably mounted close to a member which co-operates with the roller to form a channel into which the peas are fed, and means for rotating the roller so that the peas having roughened or pitted surfaces are carried out of the mass and discharged over the side of the roller, and the remainder passes along the channel. As shown, the rollers A, A<1>, roughened on their surfaces in the manner of a rasp, are mounted in bearings c, c<1> in a bifurcated support B<3> pivoted to the main frame B at B<4> and adjustably secured to a quadrant B<6> so as to vary the height of one roller relatively to the other. The material to be separated is fed into one end of the trough A<3> from a hopper D and shoot D<1>, preferably with intermittent delivery by a rotating gapped disc. A trough F with spout F<1> receives the material carried over by the rollers, that remaining in the trough being caused to pass to the end either by inclining the axes of the rollers or providing a positive conveyance by means of a helical rib on the surface of one or both of the rollers. Stationary or rotary brushes F<2> are provided to clean the underside of the rollers. The machine may comprise several units.

Title: Method and circuit arrangement for the conversion of a three-colour record into a four colour record
IPC: H04N1/60
Filed: 1956-11-14
Abstract: 846,713 Local copying in colour. HELL, R. Nov. 14, 1956 [Nov. 14, 1955], No. 34897/56. Class 40(3). [Also in Group XL(c)] Relates to an arrangement for converting three colour - component signals into further colour - component signals together with a black-component signal, wherein the smallest (in terms of the relative absorption of a positive image) of the original signals is selected to form the blackcomponent signal and is also subtracted from the remaining two original signals which then go to form the converted colour signals. In accordance with the invention, the converted colour signals are modified as a function V of the selected black-component signal in accordance with the relationship shown in Fig. 3, where M indicates the black-component signal and V the function. The invention, which is stated to be of general application in multi-colour printing, is of particular use with intaglio printing. An arrangement for carrying out the invention is illustrated in Fig. 5, where the original colourcomponent signal GD, R D  and BD, which may be derived by photo-electric scanning of transparencies and, if necessary, subjected to colour correction, are applied at terminals 1, 2 and 3 and the derived signals Gv, Rv and Bv are taken from terminals 4, 5 and 6 together with a blackcomponent signal S from terminal 7. Each colour signal passes through a channel comprised of a suppressor circuit 8, 9, 10, by means of which a selected one of the other signals is subtracted from the channel signal, and a variable gain, negative feedback amplifier 11, 12, 13 (see Group XL(c)), by means of which the selected signal modifies the channel signal in accordance with the function V. Associated with each channel is a pilot channel comprising a selection circuit 14, 15, 16 which receives an input from each of the other two channels and functions to select the smaller of the two inputs, and a non-linear circuit 17, 18, 19 (see Group XL(c)) which has a characteristic of the form shown in Fig. 3. The signal from the selection circuit is applied directly to the associated suppressor circuit and via the non-linear circuit to the associated variable-gain amplifier. Each suppressor allows only the amount of the applied original signal to pass which exceeds the signal applied, from the associated selector circuit. A further selector circuit 20 is connected to receive the outputs from any two of selector circuits 14, 15 and 16 and thus selects the smallest of the original signals which then goes to form the black-component signal at terminal 7. Typical circuits for the suppressor and selector circuits are described, Figs. 6-8 (not shown). A.C. or D.C. signals may be used; preferably the main channel signals. are A.C. and the pilot-channel signals D.C.

The shaft 19 also carries a disc 15 having cam surfaces 16 for actuating the piston of a pump to deliver oil or grease to the nozzle when the latter has been lowered by the action of cam 32 and a spring pressed check valve in the nozzle end dips below the upper rim of the pan. The pans are guided by top rails secured to frame 5 and by side rails 37.  The chains are driven by an electric motor and to allow backward movement of <PICT:0849498/III/1> <PICT:0849498/III/2> <PICT:0849498/III/3> the pans, where necessary, a ratchet wheel 20 on shaft 19 and an arm 21 on the frame cooperate to stop the paddles 10 in a position which permits the pans to pass over them.  In a modification, Fig. 6 (not shown) the pans are fed through the machine by table top chains and the mechanism is enclosed in a stainless steel casing with a hinged lid.

The resin solution may also contain caprolactam, sugars, toluenesulphonamide, glycols and glycol ethers and acid catalysts. The silicate may be lithium, sodium, potassium or a quaternary ammonium silicate. After curing the laminates may be reshaped, or bent whilst being heated if in the resin solution the formaldehyde/3NH 2  ratio is between 1 : 1 and 1À5 : 1.

Title: Frequency generator
IPC: G08G1/081
Filed: 1965-08-20
Abstract: 1,115,603. Road traffic signals. E. W. BLISS CO. 20 Aug., 1965 [1 Sept., 1964], No. 35896/65. Heading G4Q. In a road traffic signal system the cycle time is varied in accordance with traffic flow by varying the division ratio of a divider fed from a master oscillator locked to mains frequency. In Fig. 2 the output of the oscillator 12 is converted into pulses and fed to a five-stage binary counter C each stage of which is coupled to six count signalling circuits L1-L6. Each of these circuits is adapted to produce an output when a predetermined count is reached, for example counts of 8-13 respectively, thereby giving a corresponding division ratio. Selection of one of circuits L1-L6 is determined by relays CR1-CR5, one or none of which is energized in accordance with the maximum traffic flow recorded by three inbound detectors D1-D3 or three outbound detectors D4-D6, Fig. 1 (not shown). The output of one of circuits L1-L6 passes to a pulse generator (PG, Fig. 2A, not shown), which changes the state of a bi-stable circuit (30) and after a short delay provides a resetting pulse for the counter C. The bistable (30 controls the conduction of a transistor (32) which in turn controls a silicon-controlled rectifier (46) in parallel with an output potentiometer (50). The input to the potentiometer may be the pulses supplied to the counter C, or a different carrier, or a direct voltage, and the output is supplied through an amplifier to local controllers which recover the square wave modulation and use it to supply synchronous motors (M). Other local controllers (LC3, LC4, Fig. 1) not controlled by the master controller are synchronized by the A.C. mains. In modifications, Figs. 6 and 7 (not shown), the oscillator 12 is replaced by a magnetic gearwheel (58) driven directly or through gearing by a synchronous motor (56) and providing an output to an adjacent stationary magnetic pick-up (66).
