Title: Machines for cutting shaped pieces from sheet material
IPC: B26D1/60
Filed: 1955-08-02
Abstract: 783,650. Cutting-machines. SVIT, NARODNI PODNIK. Aug. 2, 1955 [Aug. 2, 1954], No. 22153/55. Class 31 (1). A machine for cutting shaped pieces from plastic or other sheet material 11 comprises a knife carrier 2 which is guided, by means of rollers 3 movable along rails 4, to carry out a reciprocating movement between a rest position, Fig. 1, and an end position, Fig. 2, which is biased to return from the end position to the rest position and carries knives 1, means for moving a driven pressure roller 5 into contact with the knives so as to cause, by frictional engagement, the knife carrier to advance towards the end position, and automatic means to move the roller 5 away from the knife carrier when the latter has reached the end position so as to allow the knife carrier to return to its rest position. The roller 5 is rotatably mounted at the end of one arm of a bell-crank lever 7, the other arm of which is actuatable by the rod 8 of a piston and cylinder device 9, 10. The knife carrier is provided with projecting bars 6 of resilient material. The sheet material 11 is conveyed by means of belts 12, 13 over the roller 5 and then to a discharge belt 14. The turning movement of the roller 5 acts to tension a helical spring 21 through the movement of a gear associates with the spring along a rack 20 so that when the roller 5 is moved downwards, the knife carrier is returned to its rest position by the action of the spring 21, the force of the resulting impact being reduced by means of an adjustable brake 22. The roller 5 and belt conveyers 13, 14 are driven from an electric motor 15 through a clutch 17 and belt drive 18, 19. A dog on the knife carrier is engageable with abutments 24, 25 on a rod 23 which actuates a switch for stopping and starting the motor 15. In operation, the belts 13, 14 are caused to move as long as the roller 5 is pressed against the knives 1 and bars 6. The movement of the knives 1 and bars 6 over the roller 5 causes the knives to be pressed into the material to cut shaped pieces therefrom. At the end of its movement, Fig. 2, the knife carrier engages the abutment 25 to interrupt the current to the motor 15. The belts 13, 14 are then stopped, the roller 5 moved away from the knives, and the knife carrier returned to its rest position, Fig. 1, by means of the released spring 21. At the end of its return movement, the knife carrier engages the abutment 24 so that the current to the motor 15 is restored and the cycle repeated.

Title: Arrangement for determining the quantity of fuel injected in mixture-compressing internal combustion engines
IPC: F02D41/34
Filed: 1975-05-22
Abstract: 1516411 Automatic control of fuel injection to I C engines ROBERT BOSCH GmbH 22 May 1975 [5 Dec 1974] 22155/75 Heading G3N The fuel injection period of an I.C. engine is determined by the final voltage on the timing capacitor of a monostable circuit, which capacitor is charged through a circuit whose time constant is inversely proportional to the position of the throttle valve for a period determined by the engine speed. The circuit shown includes transistors T1, T2 connected as a monostable multi-vibrator whose unstable period is determined by the initial charge on capacitor C1 and produces a pulse output on the collector of transistor T2 which is used as the injection pulse. Effectively capacitor C1 is charged through the phantom resistor RE and discharges through resistor R4 under the control of engine speed pulses applied through resistor R and diode D1 to the base of transistor T1. The phantom resistor is shown to be equivalent to the arrangement shown including transistors T3, T4 and its value depends on the setting of potentiometer P1 connected to the butterfly valve so that the charge in RE is inversely proportional to the angle α of the butterfly valve. In operation the receipt of an engine speed pulse 6a causes transistor T1 to conduct and a differentiated negative pulse UN (6b) equal to the instantaneous voltage on capacitor C1 is applied to point S which turns off transistor T2 to produce an output voltage 6c. The voltage at point S is dissipated through resistor R4 until the voltage VP is reached when transistor T2 conducts to define the end of output pulse t i . The capacitor C1 then recharges, Fig. 6d, at a rate dependent on the position of the butterfly valve until the next speed pulse is received. The time ti is thus dependent both on throttle position and engine speed. Resistor R7 is used to set an idling level of fuel supply.
Patent GB-1580829-A (GB)
Title: Tyre chains
IPC: B60C27/08
Filed: 1977-05-25
Abstract: The tyre chain is composed of chain links (1, 2) which are arranged upright and, respectively, horizontally and form meshes composed in each case of four chain links (1) which are arranged upright and are joined to one another by a chain link (2) which is arranged horizontally. The mesh area bounded by adjacent junction points (4) and the free link-aperture area bounded by the chain link (2) which is arranged horizontally and is elongate, are essentially of the same size. By this means, uniform wear of the tyre is achieved. Due to the elongate design of the chain links (2) forming the junction points (4) a considerable saving in chain links is achieved for a given chain length. The tyre chain is of a low weight, as a result of which small centrifugal forces and only a low degree of inner wear of the tyre chain occur during driving. The elongate chain links (2) rotate with their longitudinal axis in each case in the direction of the main force component, as a result of which a self-tightening effect is achieved. <IMAGE>

Title: Improved hoist
IPC: B66D3/18
Filed: 1949-08-29
Abstract: 665,527. Hoists. WILSON, S. Aug. 29, 1950. [Aug. 29, 1949] No. 22410/49. Classes 78 (iii) and 78 (v). A hoist has a rig adapted to be mounted in an elevated position, the winch being hoistable under its own power from an initial position where it rests on or is supported from the ground without any anchorage to a position in the locality of the rig, and means being provided for securing the winch in such locality. A winch 2 has a winding drum 6 mounted on a shaft 13 operated through gearing driven by a motor 5, Fig. 1. The drum is driven by a clutch which comprises shoes 17 brought into engagement with the flange 16 by pulling a cord 29 attached to a bell crank lever 26 which operates a wedge member 19 through a rod 28, lever 31 and rod 20. The drum is braked by shoes 22 which normally are held in the brake on position by a spring 25 but are released by pulling a cord 35 which operates through a lever 33 and rod 24 to release the brakes from the spring pressure. Pulling the cord 29 puts in the clutch and releases the brake, whereas pulling the cord 35 releases the brake leaving the clutch inoperative. The cable 37 secured to the drum 6 passes upwardly between guide rollers 38 through a tube 40 and conical member 41, through a stop member 48 round sheaves through an angle member 54 and spring 55 to a fall block 56. A latch 59 slides between guide plates 58 and has connected a pair of bell crank levers 62 secured to a spring 65. A pair of finger pieces 70 secured to a lever 66 project into the path of the lever 62. The forked ends of the lever 66 straddle the hook. In operation, the cable 37 is wound until the fall block engages the spring 55 and when the latch 59 is moved to the right further winding hoists the winch past the latch which engages beneath the conical member 41 and holds the winch in the elevated position. To release the winch to ground level, the cord 29 is pulled to raise the lever 66 to move the latch 59 to the inoperative position, then releasing the clutch and releasing the brake by the cord 35, the winch descends under its own weight.

Abstract: 1,182,012. Silicate fibre containing refractory compositions. FOSECO TRADING A.G. 15 May, 1967, No. 22444/67. Headings C3N, G3P and C3R. A silicate fibre containing foamed refractory heat-insulating composition is produced by mixing a granular or powdered refractory material, silicate fibres, sufficient foaming agent to cause the composition to foam during mixing and a liquid binder which is an aqueous alkali metal silicate or a settable synthetic resin or precursor therefor, the silicate fibres being the only fibrous material present. In the example an aqueous solution of a blend of the sodium salts of alkylaryl sulphonates was used as the foaming agent and was added to a mixture of the refractory, e.g. silica flour or fine silica sand, and liquid urea-formaldehyde resin, and after foaming the silicate fibres, e.g. slag or rock wool, asbestos or an alumino-silicate, were added. Other materials suitable as the various ingredients are also specified. A defoaming agent, e.g. hexanol, may be added to the above composition which may be used to form slabs and sleeves to line the head of an ingot mould and for lining a head box for such a mould. When producing the slabs and sleeves the hardening of the alkali metal silicate may be accelerated by passing an acid gas (e.g. CO 2 , S0 2 , HCI, S0 3 ) through the composition.

Title: Improvements relating to cathode ray tube circuits
Inventor: BILLIN JAMES JOHN
IPC: H04N3/185
Filed: 1949-08-30
Abstract: 678,173. Automatic voltage regulation; rectifying. ELECTRIC & MUSICAL INDUSTRIES, Ltd. Aug. 30, 1950 [Aug. 30, 1949], No. 22448/49. Classes 38 (ii) and 38 (iv). To compensate variations of the E.H.T. volts on the anode of a C.R. tube resulting from variations of the mean brightness of the reproduced picture by variations of the cathode/ anode electron beam, the E.H.T. voltage, which is derived from the diode/condenser combination 12, 13 in the output of valve 1 during " fly-back " of the saw-tooth voltages via condenser 8, is controlled in accordance with the mean beam current by a resistor 10 which has a negative-temperature coefficient and is heated by a resistor 18 in the beam circuit. The resistor 10 controls the time constant of the saw-tooth circuit, the maximum effect being produced on the steep flank of the saw-tooth and hence on the rate of current variation in the output circuit of the valve 1 during " flyback." The amplitude of the output pulses and the value of the rectified voltage across condenser 13 are therefore varied to maintain the E.H.T. volts substantially constant. Specification 678,156 is referred to.

Abstract: 709,334. Electric clocks. SYNCHRONOME CO., Ltd. Sept. 18, 1951 [Sept. 18, 1950], No. 22885/50. Class 139. A secondary clock comprises a pawl which is reciprocated to drive a ratchet wheel, an electromagnet by which the pawl is periodically disengaged from the ratchet wheel and which is energized through an electric circuit including a mercury switch which is normally open and is movable to closed position by a projection moving with the ratchet wheel, and a catch by which the switch is held closed, said catch being movable, to release the switch so as to re-engage the pawl with the ratchet wheel, by an electromagnet which is energized by an impluse from the master clock. The ratchet wheel 19, Fig. 1, is stepped-on by a pawl 18 freely pivoted to a crutch 17. The ratchet wheel 19 is connected through a worm and worm wheel 21, 22 and suitable gearing to the hands 24 of the clock. A stud 25 projecting from the ratchet 19 rocks a rocker 27 every revolution and a mercury switch 29 carried thereby is closed to close a circuit from a battery, (not shown), to an electromagnet 30 which is energized to lift the pawl 18 from the ratchet 19. The rocker 27 is retained in this position by a spring-loaded catch 32 integral with an armature 34 of an electromagnet 35. When the electromagnet 35 receives an impluse from a master clock the armature 34 and catch 32 are moved to release the rocker 27 to return to its initial position opening the mercury switch 29 to de-energize the electromagnet 30 and allow the pawl 18 to again drive the ratchet 19. A lever 40 may be manually moved to move the rocker 27 to close the mercury switch and thereby arrest the drive. The hands of the clock may be advanced by operation of a hand wheel.. Specification 709,335 is referred to.

Abstract: 650,857. Smoothing pulsating currents. SCOLES, G. J., and METROPOLITANVICKERS ELECTRICAL CO., Ltd. Sept. 2, 1948, No. 23173. [Class 38 (ii)] A choke-capacitance or resistance-capacitance filter network for smoothing a fluctuating unidirectional current has means provided whereby a point D in the network at or towards the output end where fluctuations are liable to occur coupled through a potential dividing circuit C2, C4 to a point B nearer the input so that the point at which fluctuations may occur is fed with a compensating voltage substantially equal and opposite in phase to the fluctuations. The tapping point of the potential divider C2, C4 is coupled to the later point D through a condenser C3. By the use of this circuit a smoothed output current is obtained, the condensers C2, C3 being of smaller size than those normally used in smoothing networks while the condenser C4 may be of a low voltage type. The resistor R is provided to ensure that the voltage across C4 does not exceed the ripple amplitude. A resistance-capacitance filter circuit is shown in another embodiment, the neutralizing coupling in this case being across two resistance stages.
