Title: Improvements relating to information transmission systems
IPC: H03M3/02
Filed: 1970-07-03
Abstract: 1,254,820. Delta encoder. TEXAS INSTRUMENTS Ltd., and C. S. DENBRINKER. 3 July, 1970, No. 32490/70. Heading G4H. In a delta encoder (Fig. 1) in which the counter 3 in the transmitter is incremented or decremented one unit in accordance with whether an input at terminal 1 exceeds or is less than the previous input level represented by the count in counter 3 a count up/count down pulse being transmitted via a gate 7 through the receiver RX, when the counter is full or empty, gate 7 is inhibited and count up or count down pulses respectively are transmitted so that the receiver counter is stepped to bring it into synchronism with the transmitter counter. The counters ignore pulses tending to make them exceed their maximum and minimum values so that if the input is above the level represented by the counter 3 the counter will remain full at this time. If however the maximum count represents the maximum possible value of the input when the input is at its maximum the comparator 2 will result in alternate count up and count down signals being generated but the count down signals will not be transmitted since gate 7 is inhibited during them. As described the input signal is in analogue form the count in counter 3 being converted to analogue form in a D/A converter 4, gates 12, 13 connected to the outputs of counter 3 control the closing of gate 7 and the transmission of the pulses at full count and empty count. At the receiver a counter 15 accumulates the transmitted pulses, the counter outputs being connected to digital to analogue converter 16. Alternatively the input or output could be digital. The system may be modified to transmit three state signals representing count up, count down and no change instead of the two state signals of the embodiment of Fig. 1.

Title: Method and apparatus for determining the unbalance of a rotating body
IPC: G01M1/22
Filed: 1973-07-09
Abstract: 1393624 Measuring rotary imbalance HOFMANN GmbH Gebr] [trading as  HOFMANN KG MASCHINENFABRIK Gebr] 9 July 1973 [28 July 1972] 32561/73  Heading G1N In an apparatus for measuring rotary imbalance the output of a transducer is converted into two rectified signals in known manner to represent the x and y co-ordinates of the imbalance, and the signals are then smoothed by a circuit whose time constant becomes longer as the measuring continues. The circuit is basically an R C filter which removes interference and harmonic signals; to operate efficiently such a circuit requires a long time constant and would consequently require a long time for the capacitor to charge to the level of the rectified signal. The resistor is therefore varied from an initially low value, which allows the capacitor to charge rapidly, to a high value where filtering is more effective. The final voltage on the capacitor represents the magnitude of the x ory component. In Fig.3 one of the rectified signals is supplied to terminal I and passes via FET 18 to R C filter 6, 8. The voltage stored on capacitor 8 is available at low impedance point 12. A modulator 24 supplies pulses to FET 18 to switch it on and off. The modulator is controlled by the voltage on capacitor 17. When the apparatus commences a measurement the capacitor is initially at a high voltage and the modulator supplies pulses to the FET such that it is on for most of the pulse cycle. The storage capacitor 18 thus charges rapidly to the mean D. C. level at terminal 1. As the modulator capacitor 17 discharges, the FET is switched on for progressively shorter times, until it is effectively off. The high resistance of the FET then produces a large time constant with capacitor 8 and removes unwanted components of the input at 1. A further filter may be added to the R C filter of Fig.3. As shown in Fig.5 the extra components are R C filter 35, 38, two diodes 36, 37 and switch 39. One of the diodes will conduct, depending on polarity, when large voltages appear across it early in the measurement, but as capacitor 38 charges the diode threshold is not exceeded and the extra filter then has a large time constant. Switch 39 may be opened at the end of the measurements to prevent discharge of capacitor 38.

Abstract: 921,196. Wagon tippers fitted with vibrators. SIEMAG MASCHINEN-UND STAHLBAU WETPHEN G.m.b.H. Oct. 2, 1959 [Oct. 4, 1958], No. 33428/59. Classes 78 (1) and 78 (4). In a tipping operation, vibration device 50 assists tipper 1 to discharge material from truck 2. Device 50 includes a vibrationreceiver 8, a vibration-generator 7, and two electromagnets 9, and is mounted on frame 6 carried by arm 3 pivoted at 4 to tipper 1. When the tipper 1, and with it the truck 2, rotates so as to discharge the latter, a switch is operated to energize the electromagnets which are attracted by the body of the truck 2 and strike it, thus causing it to vibrate; and the vibrations are transmitted by pin 8<SP>1</SP> to vibrationreceiver 8. The latter converts the physical vibrations into electromagnetic vibrations and transmits them via cable 11 to amplifier 12; and the amplified vibrations are transmitted back along cable 11 to vibration-generator 7. The latter converts them into physical vibrations which are passed to the truck 2. The truck 2 therefore vibrates continuously at its own frequency at the same time as it is being discharged.

Title: Improvements in upsetting or forging machines
Inventor: FOSTER JOHN
IPC: B21D19/02
Filed: 1969-07-03
Abstract: 1,224,259. Forging; rolling. B. & S. MASSEY Ltd. 3 July, 1969, No. 33510. Headings B3H and B3M. A forging apparatus comprises a die 11 formed of movable parts 14, 23 and an ejector 26 and a die 10 adapted to carry out circular rocking motion about a point. The die 11 has a workpiece receiving recess 13 in a block formed integral with or mounted on the part 14 which acts as ram. A flange 15 on the ram is provided with a pair of hydraulic or pneumatic jacks 18. The other part 23 also acts as a ram movable inside the ram 14 by similar drive means. The ejector 26 is similarly operated within the part 23. A stop 30 is moved under the ejector after it is raised to hold the ejector relative to the die. The position of the stop 30 is adjustable. Ejection is effected as the rams are retracted. In operation a billet is placed in the die 11 and the ram 14 moved towards the die 10 by the jacks 18. The rams 14, 23 are then advanced together to upset the billet. During forging the ejector is advanced to form a blind bore in the billet. In an alternative embodiment the cylinder for the second ram (123), Fig. 2 (not shown), is formed within the main ram (14). In a further embodiment the cylinders for the second ram 200, Fig. 4, and the ejector 201 are formed within the main ram 14. In the above embodiments the rams preferably act vertically. In a further embodiment, Fig. 5, the rocking die 211a is mounted on a fixed cross-head 210 and the die 212 on a movable cross-head 213. The bore of the cross-head 213 has a wear resistant sleeve 215 which is removable for replacement by a sleeve with a different bore. A ram cross-head 216 has a main ram 217 and a second ram 218. The main ram serves to move the cross-head 213 towards the die 211a and the second ram moves bar or tube stock through the sleeve towards the die before movement of the cross-head 213. The upset stock may be ejected by the second ram 218 although it is preferable to move the cross-head 213 out of the press axis for ejection by a ram. One arrangement of this type has a pair of crossheads (213), (213a), Fig. 6 (not shown), which are alternately pivoted into the press axis. Alternatively the dies (221), (222), (223), (not shown), may be mounted on a turret for successive co-operation with a rocking die (211a). Two rocking dies (252), (252a), may be provided to initially upset the billet and finally forge it. The spare stations are used for loading and ejection. Instead of rotating the bolster the dies may be arranged on a linearly reciprocating bolster. The fluid lines are controlled by valves which may be automatically controlled.
