Title: Data processing system
IPC: G06F17/50
Filed: 1974-02-14
Abstract: 1452186 Data processing system INTERNATIONAL STANDARD ELECTRIC CORP 14 Feb 1974 [21 Feb 1973] 6752/74 Heading G4A [Also in Division H4] In a data processing system comprising a number of operational computers 1A-1N and a simulation computer 6 arranged to simulate the activity of a group of peripheral devices, a timing and synchronising system includes a common real time counter counting operating cycles of the operational computers, the counter being stopped when one of the operational computers stops, and a further counter associated with each operational computer, each further counter counting any additional cycles performed by the associated operational computer after a stop, the restarting of each operational computer being delayed for a number of cycles given by the contents of its associated further counter in order to maintain synchronism between the operational computers. A group of operational computers 1A, 1B, ...., IN are controlled by a simulation computer 6 via an interface 7. Signal delays cause the operational computers to respond to control signals after a delay ts and the controlling system to receive signals from the operational computers after a delay th, ts and th being variable but such that for each operational computer ts +th = tn which is constant. A real time counter counts clock pulses, a start command from simulation computer 6 causing all operational computers to start, each after the appropriate delay ts and the real time counter to start after a delay tn. When one of the operational computers, say 1A, stops, a stop signal received after the appropriate delay th stops the real time counter and starts counters associated with each of the remaining computers which, together with their associated counters, are stopped at the end of their current instructions. When a start command is issued the process repeats except that each computer whose associated counter is non-zero is not started until the counter has been counted down to zero. In this way the number of operational cycles performed by each computer is given by the sum of the contents of the real time counter and its associated counter. The simulation computer 6 has a conventional input/output peripheral system 10.

Abstract: 435,733. Valve circuits. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Electra House, Victoria Embankment, London.- (Assignees of Barton, L. E. ; 228, Burrwood Avenue, Collingswood, New Jersey, U.S.A.) March 6, 1935, No. 7057. Convention date, March 31, 1934. [Class 40 (v)] Hum due to energization of thermionic valves from rectified A.C. supply is compensated by a series of filters responsive respectively to the fundamental hum frequency and several harmonics thereof, the phase and amplitude of the filter outputs being adjusted and combined, then applied to the valve circuit in such manner as to balance out the disturbing currents. In Fig. 1, 11 is the delta-connected secondary of a transformer fed from a three-phase source PS, a neutral point being obtained by a starconnected resistance system 17. A series of filters f ... 6f are fed from potentiometers 19 ... 23, which are connected between the neutral 18 and potentiometers 12 ... 16. Potentiometer 12 may be connected by means of switch 24 across any of the phases a, b, c and supplies filter f which selects the fundamental ripple frequency. Potentiometer 13 may be connected across phase a or c by means of switch 25, its filter 2f being designed to pass the second ripple harmonic. Potentiometers 14, 15, 16 are across phase a and supply filters 3f, 4f and 6f which produce third, fourth and sixth harmonics respectively. The combined outputs from the filters are applied to an amplifier 66 and thence through transformer 67 to the circuit of a voice frequency modulator M for a transmitter T, which derives its heating anode and grid bias potentials from the threephase source PS and rectifier R. Filter f comprises an iron-core transformer 27, Fig. 2, the primary of which is tuned by condenser 28 to the fundamental ripple frequency, while filter 2f, Fig. 3, comprises a frequency doubler and filter consisting of a double-diode triode 55 acting as a full wave rectifier and amplifier, the output filter 34, 35 being tuned to the. second harmonic. Fig. 4 shows the third harmonic filter 3f comprising a full-wave rectifier 53 acting as an energy absorbing device which throws back into the primary of transformers 30 and 39 a current rich in harmonics, from which the desired third harmonic is selected by filter 43, 44 and stopper circuit 45, 46. Filter 4f comprises a rectifier and transformer similar to 53, 30 of Fig. 4, with the doubling circuit of Fig. 3 replacing the resistance-condenser combination 41, 42, and circuit 39, 45, 46, 44, 43 omitted, (Fig. 5 not shown). The sixth harmonic filter is in effect a combination of Figs. 3 and 4, (Fig. 6 not shown). The system has particular application to medium and high-power radio transmitters.

Abstract: 1,007,896. Inductors. PYE Ltd. Feb.27, 1962 [March 1, 1961], No. 7464/61. Heading H1T. [Also in Division H3 and H4] The invention relates to tuning an aerial (see Division H4) by means of an adjustable coil or coils 31, 32 within a fibre glass housing 2 and connected in series between a whip aerial element 1 and a further radiating element. In the embodiment shown, a plurality of adjoining ferrite blocks 25 held together by resilient pads 26 are enclosed within that part of the threaded fibre glass tube 24 on which the coil 31 is wound whilst the coil 32 is wound on a part of the threaded tube 24 (or rod) which has a metallized non-magnetic surface 30. The coils 31 and 32 are joined by conductor 29 which passes through nylon nuts 28. Each nut 28 is provided with a projection (not shown) which slides in a longitudinal slot in the wall of the housing 2. As the tube 24 is rotated by drive means 14, turns are removed from one coil and replaced on the other thus changing the resonant frequency of the aerial. In a similar embodiment (Fig. 1, not shown) only one coil and one nylon nut are provided, the coil being wound directly on to the fibre glass former. When the former is rotated, to add or subtract turns from the coil and the slack in the coil being taken up by a tensioned roller. In a further embodiment (Fig. 3 not shown) a fixed coil is formed from part of a copper tape extending between the ends of the housing and embedded therein or formed on the inner wall thereof. This coil is associated with two movable cores, one ferromagnetic and one of conductive paramagnetic or diamagnetic material. The cores are moved by a cable acting against a control spring. In this embodiment the housing is filled with oil and alumina. In each embodiment the tuning may be metered by means of a current transformer (the ferrite core of which is placed around the feeder to the aerial). After rectification this transformer output may be used to give a visual indication on a meter or to drive the means by which the inductance is varied.

Abstract: 669,342. Lathes; chucks. MERCER, G. H., and LABAN, W. H. March 20, 1950 [March 19, 1949], No. 7524/49. Class 83 (iii). [Also in Group XXVIII] Lubricating cutting-tools and work.- In a metal-cutting machine for supplying cutting lubricant to the work 10 or to a tool 13, the work gripper is operated by a fluid-pressure actuated piston 12 controlled by a valve 25 which interrupts the supply of pressure fluid to the piston when the tool is not in operation, the valve also controlling the supply of pressure fluid to a force pump 4 which is operated so as to provide a supply of cutting lubricant to the work or tool only when the work is gripped by the work gripper. A pipe 44 connects the valve body to a source of pressure fluid, and a pipe 45 from the valve body communicates with a pipe 54 leading to the force pump and also with a pipe 68 leading to the piston 12, a further pipe 66 leading from the delivery port of the pump to the cutting position. Valves 34, 35, Fig. 4, in the valve body, control the flow and exhaust of the pressure fluid, the stems 32, 33 of the valves being actuated by a cam 26 which is oscillated by means coupled to the operating lever 18 of the tool-holder 14. The pump, Fig. 3, comprises a cylinder 49 fitted with inlet and delivery valves 60, 64, respectively, and a piston 52 which is operated on the delivery stroke by the pressure fluid and on the return stroke by a spring. The cylinder is provided with transverse walls 55, 56 between which are provided inlet openings 57, covered with wire gauze, for the cutting lubricant 58. In operation, when the lever 18 is operated to bring the tool into the cutting position, the cam is moved automatically to open the valve 34 and close the valve 35. The pressure fluid received from the pipe 44 then passes through the pipes 45, 54, and 68 so as to operate the pump and the work gripper actuating piston 12. When the lever is moved back to its original position to move the tool away from the work after severing a portion thereof,' the cam 26 is turned to close the valve 34 and open the valve 35. Communication with the source of pressure-fluid is now cut off, and the pressure fluid in the cylinder 49, in the work gripper actuating piston and in the pipes 45, 54 and 68 then passes to the exhaust pipe 42 of the valve body and into a vessel 43.

Abstract: 1,184,843. Coin separator. NATIONAL REJECTORS Inc. 15 Feb., 1968 [13 March, 1967], No. 7554/68. Headings G4V and G4X. Apparatus for separating coins having milled peripheries from coins having non-milled peripheries comprises a coin passageway, a shoot for receiving non-milled coins leaving the passageway, a shoot for receiving milled coins leaving the passageway and disposed beyond the first mentioned shoot in the direction of coin travel, a separator intermediate the shoots, a movable element disposed in the passageway to engage the periphery of a coin moving along the passage whereby the coin is slowed, a milled coin being slowed to a greater extent than a non- milled coin, and a deflector positioned so that a non-milled coin leaving the passageway strikes the deflector and is directed into the non-milled coin shoot and so that a milled coin leaving the passageway will pass between the deflector and separator into the milled coin shoot. As described the apparatus is adapted to accept 10 and 25 cent pieces. A 10 cent coin falls between the fingers 161, 163 of a cradle 160 and is deflected by a member 174 through an opening in wall 20 to runways 106, 104 (Fig. 1) where its milled periphery is engaged by milling on the runway 104 and by a pivoted hook 76 to retard the coin which falls to the left of separator 130. Unmilled or smaller discs pass unchecked and rebound from projection 122 to fall to the right of separator 130. A 25 cent coin is directed by cradle 160 on to runway 182 where its milled periphery is engaged by milling on a weighted wheel 228, carried by a pivoted lever to brake the coin which falls to the right of separator 60, Fig. 4. Unmilled or smaller discs are not slowed and rebound from a deflector to pass to the left of the separator. Permanent magnets may be included in bosses 194, 196 and circular discs of magnetizable material mounted opposite on wall 20. In another modification a counterweighted lever having a pointed end is pivoted above the runway 182 to retard milled coins. Clearing apparatus.-An oversized disc on runway 104 is held by hook 76 engaging slot 71 in member 66. Initiation of the scavenging operation depresses roller 84 on scavenging lever 80 to rotate the lever about pivot 78 causing pin 86 to rotate lever 88 anti-clockwise, Fig. 1, into contact with roller 108 camming wall 98 rearwards. A link 92 secured to lever 88 rotates member 66 anti-clockwise causing hook 76 to move the disc to the right into the rejected coin shoot 118. A disc of larger diameter will contact a stud 44 causing a pendulum 42 to engage a stop 46 and hold the disc on the cradle. On clearing, lever 80 pivots to engage roller 180 and cam gate 146 away from wall 20 pushing the disc against one of the fingers of plate 202 and into the rejected slot 118.

Title: Improvements in and relating to turbines and like machines
Inventor: SHEETS HERMAN ERNST
IPC: F01D5/14
Filed: 1959-03-05
Abstract: 872,228. Boundary layer control. GENERAL DYNAMICS CORPORATION. March 5,1959, No. 7669/59. Class 4. [Also in Group XXVI] A turbine or blower blade of aerofoil section has a slot connecting the high and low pressure faces thereof, the minimum width of the slot lying in the range 2 to 2À66 times the thickness of the boundary layer at the location for the slot exit on the low pressure face at the design operating condition of the blade. Preferably in a blade of the laminar-flow type, the slot opens into the low pressure face along a line located in the transitional region between laminar and turbulent boundary layer flow, or located between the forward and rearward lines of maximum frictional intensity (the product of the viscosity and the velocity gradient in the boundary layer). The slot inlet on the high pressure surface should be in the transitional region between laminar and turbulent boundary layer floor on that surface. In a non-laminar flow blade, the slot exit in the low pressure face lies within the range from 5 to 7% of the blade chord, downstream of the line of maximum static pressure increase following the line of minimum static pressure at the design operating conditions of the blade. The boundary layer on the high pressure surfaces is thus removed at the slot, and that on the low pressure surface energized at the slot, resulting in higher efficiency. In the Figure the slot divides the blade, of chord c, into leading and trailing aerofoil portions. The entry width m of the slot should be greater than the exit width s, the latter being between one half and five% of the chord c. Similar limits are given for the length o of the slot, which may increase from tip to root of the blade. The maximum distance n y  of the mean camber line from the chord line should be at a station n x  near the rear part of the leading portion. The angle #F between the chord line c<SP>1</SP> of the leading portion and the overall chord line should be smaller than the angle #R<SP>1</SP> between the line joining the trailing edges of the two portions and the overall chord line. The angle between the trailing edge of the high pressure surface of the forward portion and the chord line of that portion should be greater than the angle formed between the tangent to the lower pressure surface of the rearward portion at the slot exit and the chord line of the forward portion. The camber angle # of the blade should increase from tip to root. The two portions may be connected across the slot by a stay of small radial dimension. The slot may be formed in rotor or stator blades. The power consumption required by a blower at flow capacities less than the design capacity, and the amount of airborne noise produced, are stated to be reduced if the minimum width of the slot lies between two and four% of the total blade chord, the slot being located at between 55 and 70% of the chord from the leading edge.
