Title: Serial printing arrangement
IPC: B41J7/34
Filed: 1970-05-20
Abstract: 1316621 Control of printing machines ING C OLIVETTI & C SpA 20 May 1970 [23 May 1969] 24492/70 Heading G4H [Also in Division B6] A serial printer (see also Division B6) comprises a carriage permitting relative movement between a tyre head and a paper support, the carriage being driven through an endless band by a reversible stepping motor 93 under control of a comparator 173 which compares the contents on lines 174 of a register (not shown) indicating the required position of the carriage with the contents on lines 172 of a counter 171 indicating the current position of the carriage. The comparator 173 emits signals M1, M2 according to the direction of motion required of the carriage, each signal presetting an AND gate 166 or 167 the outputs of which are applied to a two-stage counter 165 controlling rotation of the motor 93 in either direction. The start of a line is established by depressing a key 147 whereby the carriage is driven backwards through a signal Z until a photoelectric cell 97 is energized by light reflecting off a plate (99, Fig. 1). Simultaneously, the signal Z sets a type disc (69) in home position whereat a photoelectric cell 90 is energized by reflection, the type disc being rotated by a stepping motor 66 under control of a comparator 134 comparing the required character on lines 135 with the positioned character indicated by a counter 132, a coincidence causing presetting of an AND gate 145 which actuates a print solenoid 82 when opened by a signal 14 from a counter 139 and a signal M indicating that carriage movement has ceased. Character spacing is controlled by a signal M4 after a print operation, a space is caused by a signal M5 from a space bar, back space by signal M6 from a back space key, and carriage return by signal M7.

Abstract: 762,643. Shovelling machines. AVELING-BARFORD, Ltd. Aug. 19, 1955 [Aug. 24, 1954], No. 24566/54. Class 68 (1). In a power operated crowd face shovel one end of the rope 50 of the bucket arm hoisting tackle is wound about a winch 26 and then having been passed over pulleys 45, 51, 46, of which the pulleys 45, 46 are mounted on the jib 23 and the pulley 51 is mounted on the bucket arm 38, the rope 50 is so wound about a winch drum 29 connected by a chain drive 35, 52, 41 to a winch 40 for crowding and retracting the arm 38 that the torque applied to the winch drum 29 due to the tension in the rope 50 tends to produce crowding of the bucket arm. The winch drums 26, 29 are mounted about a driven shaft 19 and are individually coupled to the shaft by clutches 27, 31 and controlled by brakes 28, 42. A drive in the reverse direction to that due to the shaft 19 may be applied to the drum 29 from a driven shaft 18, clutch 34, sprocket 25, chain 33 and a sprocket 32 secured to the drum 29. The drum 24 of the jib-hoisting winch can be coupled to the shaft 18. To raise or lower the bucket arm 38 the drum 29 is locked in a stationary position by brake 42 and the drum 26 rotated under control of clutch 27 and brake 28. For controlled retracting of the bucket arm the winch 40 is driven from drum 29 in turn driven from shaft 19 through clutch 31 under control of brake 42. For advancing the bucket arm the drum 29 is driven in the opposite direction from shaft 18 through clutch 34 and chain drive 25, 33, 32. During the last two described manners of operation the rope 50 is paid on or off the drum 26 at a rate which allows of the desired movement of the bucket arm and maintains a torque on the drum 29.

Title: Improvements in or relating to vacuum operated brakes for automobiles and the like
IPC: B60T13/46
Filed: 1923-10-03
Abstract: 228,225. Kennington, W. O. Oct. 3, 1923. Controlling different functions by same handle or lever; pneumatic transmission.-In a vacuum brake for automobiles and like vehicles, the suction of the engine is utilized to actuate the brake mechanism when the throttle valve of the engine is moved beyond the normally closed position. The intake pipe 1 of the engine is provided with a recess 3 connected by a pipe 4 with a cylinder 5 having a piston 6 secured to a brake-rod 7 and the right-hand end of the cylinder may be connected to atmosphere, or, as shown, to the carburettor side of the intake pipe by a pipe 9, so that, in the event of leakage past the piston 6, the composition of the combustible mixture is not affected. With the throttle valve 2 in the normally closed position shown, the brakes are held off by the spring 8, but if the valve is moved across the recess 3, the brakes are applied gradually. Sufficient combustible mixture leaks round the edge of the valve to keep the engine turning over. The movement of the valve 2 is controlled by a pedal 10, and when the pedal is allowed to rise, a strong spring 16 attached to an arm 12 closes the valve. As the valve closes, a projection 17 on the arm 12 engages a projection 18 on an arm 19 connected to a weak spring 20, so that further movement of the pedal is effected against the resistance of this spring, the driver being thereby apprised that the brakes are being applied. Alternatively a manuallyoperable stop may be used to arrest the pedal in the position in which the throttle is closed. Means may also be provided to permit personal actuation of the brake rod 7.

Patent GB-712283-A (GB)
Title: Improvements in tunable oscillators with automatic frequency stabilisation
IPC: F02G1/043
Filed: 1952-10-02
Abstract: 712,283. Valve generating circuits. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Oct. 2, 1952 [Oct. 5, 1951], No. 24701/52. Class 40 (6). [Also in Group XXXV] A main oscillation generator tunable to a number of closely-spaced frequencies in the region of, say, 40-60 mc/s, mixes its output in a CR tube with that of a reference standard of lower frequency, to produce new frequencies differing from that of the main oscillator by multiples of the reference frequency. In the circuit diagram a frequency standard is provided by a crystal-controlled source 27 of narrow pulses which may have a repetition frequency of 100 kc/s and a duty cycle of 1/50. The source 27 feeds tuned multiplying stages 29, 32 giving a sinusoidal output at 1 mc/s at 33. This output is supplied in push-pull to the deflecting plates 36 of a CR tube 35 which receives the output of the main oscillator on its control grid 43. The output anode 37 of the tube 35 lies in the shadow of a slotted electrode 38', so that the anode can receive current only when the beam is central. In order that this may occur only one deflection per cycle, a quadrature-phase oscillation is applied from the anode of the tube 32 to a rectifier 39 which has its cathode biased positively and its anode connected to a control electrode 38, thereby cutting off the beam except near the positive peak of the quadrature voltage. The tube thus passes current only once per cycle of the deflecting voltage, and the amplitude of the resulting pulses is a measure of the instantaneous voltage applied to the grid 43 from the main oscillator. This output is fed to a filter 20 passing a range of 1.6 to 1.9 mc/s, or tunable over this range in steps of .1 mc/s. If the main oscillator is pre-set to about 23.7 mc/s, this will beat with the 22nd harmonic of the 1 mc/s wave from the reference source 32 to produce a wave of 1.7 mc/s which is selected by the filter 20 and amplified at 21.

Title: Improvements in or relating to fluid pressure apparatus
IPC: F15B11/15
Filed: 1958-07-31
Abstract: 935,326. Drilling. BALDWIN INSTRUMENT CO. Ltd., and C. H. HAY. Oct. 29, 1959 [July 31, 1958], No. 24760/58. Class 83 (3). A machine tool comprises means for applying a fluid pressure signal to initiate a feed movement and valve means operative to prevent a subsequent feed movement until the fluid pressure signal has been re-applied. Signal fluid, entering a passage 22 passes through passages 23, 26, 15 to move a valve 12, thus allowing compressed air to pass to the operating piston 10 by way of passages 30, 31, 33. When the piston reaches the end of its stroke it operates a valve 20 to cut-off the passage 23 to unbalance a control valve 18. The control valve moves upwardly to exhaust the passage 15, allowing the valve 12 to be reversed by a spring 13 and so return the piston 10. The valve 12 cannot again be operated until the signal pressure has been cut-off and then restored, since the control valve 18 is held in its upper position by the signal pressure. In modifications, the control valve has a waisted centre portion and is engaged by a spring- controlled detent.

Filed: 1973-05-25
Abstract: 1424367 Automatic exchange systems SIEMENSAG 25 May 1973 [26 May 1972] 25096/73 Heading H4K In a PCM, TDM exchange system which interconnects incoming and outgoing highways via a time-space switching network, time slots on outgoing highways are allocated according to the extent to which the corresponding time positions are in use at the output of the time stage thereby to ensure an even distribution of traffic over the space switches during each frame. The network comprises a plurality of so called switch-through units D1-D16, which each perform time slot interchanges and spatial switching between 16 incoming highways and 16 intermediate highways, and a number of space switches K1-K16 which couple the intermediate highways to outgoing highways. In setting up a connection to a particular outgoing highway it is usually found that a plurality of free time slots are available on the outgoing highway and consequently that free time slot is selected which has a time position in a time frame which corresponds to that being least utilized by the calling switch-through unit. The switch-through units operate to interconnect the 30 time slots of each of 16 incoming highways in a non-blocking manner to the 32 time slots of each of 16 intermediate highways, i.e. by using 512 speech stores and by reading out 16 stores during the time period of one time slot. During one time position of a frame each switch-through unit can be supplying information to between 0 and 16 time slots, one being available on each intermediate highway, and by choosing a free time slot on the desired outgoing highway corresponding to the time position in which the calling switch-through unit is using least time slots, it is said that the blocking probability is reduced, the blocking probability being the probability that a chosen free time slot on the outgoing highway has no corresponding free time slot on the intermediate highway connecting the space switch K and the switch-through unit D via which the call is to be routed. Connections are of the four wire type and once the connection has been set up in one direction, the same time slots are utilized for the connection in the reverse direction.
