Abstract: 1369498 Forging CINCINNATI Inc 22 Oct 1971 [20 Nov 1970] 49208/71 Heading B3H A forging apparatus for forging powder metal preforms into, for example, bevel gears, pinions &c., comprises a feeding station 10 from which the preforms are fed one at a time to an induction station and are then discharged and fed to a press 20 while simultaneously a forged preform is transferred from the press. The heating station comprises a tube 14 and the apparatus may have a chamber 26 which encloses the press and the ends of the tube 14 and a discharge shoot 28. The preforms are loaded into tubes 11 on a turret 39, Fig. 5, which brings each tube successively into alignment with a discharge tube 12. The tubes 11 have removable caps 44 for loading and are purged by a vacuum tube 58, Fig. 5, and filled with non-oxidizing gas by a valve 46. The turret has 0-ring seals 42, 43 so that all the tubes 12, 13, 14 can contain non-oxidizing gas. The preforms are moved along the tubes by pushers 15, 16. The tube 14 is surrounded by an induction heating coil 18 and the temperature of the heated preforms is determined by a device 19. The preforms may be overheated and be cooled before being fed to the press in an extension (14b), Fig. 7 (not shown), with a cooling coil (18a) to allow controlled temperature distribution throughout the whole preform. Any preforms not at the required temperature are ejected into a bin 49, Fig. 1. The feed mechanism for the press is conventional and comprises a pair of parallel feeding bars 31, 32, Fig. 4, with spaced pairs of gripping jaws 33-35. A rest station 36 is provided between the -press 20 and the shoot opening 28a. The opening 28a is closed by a stopper 56 when the chamber 29 requires emptying. Alternatively two chambers could be provided and used alternately or an oil tank into which the end of the shoot 28 is immersed or a conveyer in a non-oxidizing atmosphere chamber to feed the parts for further treatment. The dies of the forging press may be heated by heating elements 52, 53, Fig. 1, and maintained at between 150-300‹ C. After each forging the dies are cooled by a water spray and lubricated with graphite from nozzles 54.

Title: Cathode ray tube voltage supply
IPC: H04N3/18
Filed: 1968-10-18
Abstract: 1,219,139. Sawtooth circuits. RCA CORPORATION. 18 Oct., 1968 [19 Oct., 1967; 22 May, 1968], No. 49412/68. Heading H3T. [Also in Division H2] In a power supply circuit for a cathode-ray tube, the focus electrode 115 is supplied by rectifying at 165 the flyback pulses induced in a transformer 153, the focus voltage being arranged to follow changes in the E.H.T. voltage by means of a circuit such as 183 which inhibits conduction of rectifier 165 during the first half of each flyback pulse and permits conduction during the latter half of each pulse to an extent dependent on the magnitude of the E.H.T. voltage. As shown, each sweep is provided by discharging capacitor 131 through the primary winding 153a of the line output transformer 153 under control of thyristor 127 and is terminated by each pulse from the blocking oscillator 121 which turns on the commutating thyristor 141. The E.H.T. supply is provided by rectifying the flyback pulses at 157 whilst a screen supply for the cathode-ray tube is similarly provided by rectifier 159 which supplies 1000 V. across capacitor 163. The flyback pulses have a double-peaked waveform shown at A due to tuning of the E.H.T. system to a harmonic of the flyback frequency, the second peak tending to reduce in proportion to the reduction in E.H.T. voltage (as shown in broken lines) following increase in E.H.T. loading. A further oscillation B is provided by a ringing circuit 183 connected to the primary 153a and is fed to the cathode of the focus supply rectifier 165 so as to inhibit its conduction during the first peak of waveform A and permit conduction during the second peak so that the focus voltage follows changes in E.H.T. voltage. The focus voltage may be adjusted by resistor 173 which alters the bias on the further focus rectifier 171. In Fig. 1 (not shown), transformer 153 is replaced by an autotransformer driven by a pair of parallel-connected line output transistors. A single thermionic diode (67) provides the focus supply, its cathode being fed with a differentiated version of the flyback pulses (provided by a capacitor and voltage-dependent resistor) so that the focus voltage follows changes in E.H.T. voltage. Fig. 3 (not shown) relates to line output transformer construction, the filament of the focus rectifier being supplied with a single turn winding the capacitance of which is arranged to differentiate the flyback pulse. Fig. 4 (not shown) relates to a line output transformer construction having a ringing circuit inductively coupled to the primary and connected to the anode of the focus rectifier so as to provide tracking according to the invention.

Title: Apparatus for filling containers
IPC: B65B57/06
Filed: 1971-10-26
Abstract: 1414967 Filling machines; filling containers with powders H J HEINZ CO Ltd 18 Oct 1972 [26 Oct 1971] 49706/71 Headings B8T and B8C Open ended containers 10 are advanced on an indexing conveyer 11 either by regularly spaced pegs 14 or by a worm drive. Positioned in line above the can path is a filling device 20, comprising two independent rotor housings 21 with integral apertured bases formed with a line of downwardly directed discharge ports 22 and a rotor 25 which fits closely into the lower part of the housing bore 23. The upper part of the bore is arched to produce a pocket 26 which communicates with inlet and output ports 27, 28 and is continuously fed from a pumped product supply 30, 31, 32. Each rotor has a peripheral helical groove 33 with three turns and of a width that overlies two of the discharge ports 22, and its pitch is the same as the can indexing on the conveyer. There is a common drive for the rotors 25 and the conveyer 11. The discharge ports 22 contain flexible tubes 58 which are normally pinched closed in groups of seven by obturating members (60), Fig. 4 (not shown), operated by pistons (64) in pneumatic cylinders (65) and actuated by can sensing arms 74, which normally lie in the can travel path. With no cans on the conveyer the product is only circulated through the housings. However, when a can 10 is on the conveyer 11, it engages sensing arm 74 which operates piston (64) and reverses obturating member 60 to open the first group of discharge tubes 58. The angular disposition of helical groove 33 relative to the indexing pegs 14 is such that groove 33 scans the first of the open apertures 22 and feeds the product to the first two delivery tubes. Continuing rotation of rotor 25 causes groove 33 to scan the remaining open outlets 22 is sequence at the same speed as the moving can, which, on approaching the next sensing arm 74 opens the second set of discharge tubes, so that in-line feeding can continue until the container is filled. The length of sensing arm 74 is so adjusted that, if no can is following, oburating member 60 will be closed before helical groove 33 feeds the product to an empty space.

Abstract: 1322549 Photo-electric focusing EASTMAN KODAK CO 22 Oct 1970 [23 Oct 1969] 50277/70 Heading G1A [Also in Division G2-G3] A film-strip or slide projector automatically senses and maintains the correct projection lens to screen distance and also the correct film to projection lens distance. Invisible radiation from lamp 26 is projected by filter and lens 30, 28 on to screen 16 and is reflected back to a gap between photo-cells 36 via lens 32 and a mirror 34. Output from the photo-cells passes to a differential amplifier 37 controlling forward a reverse rotation a motor 50. Light from lamp 26 is also reflected from the surface of a film 12 at the gate 13 on to the photo-cells 36. Insertion of a film into gate 13 actuates solenoid 72 to rotate lever 58 clockwise about pivot 56 whereby mask 68 on extension 66 blocks light from entering lens 32, and the drive from motor 50 is transmitted to the slidably mounted gate housing 22 by wheels 54, 60, to maintain correct focus of the projected image on screen 16. Removal of the film from the gate allows lever 58 to turn anti-clockwise under spring 64 whereby mask 68 is removed from lens 32 and the drive from motors 5 is transferred to lens housing 20 slidably mounted on pins 24. Projectorscreen distance is now controlled. Projected image size may be kept constant by means of a zoom lens on housing 20 controlled by a pivoting lever on the housing which engages a cam surface adjustable manually to correspond with the film size.

Abstract: 1402698 Resistance difference measurement, temperature measurement YOKOGAWA ELECTRIC WORKS Ltd 1 Nov 1973 [15 Nov 1972] 50825/73 Heading H3H A circuit for producing a digital representation of the difference between two resistances comprises an integrator I receiving as input an analogue signal and one of a pair of signals of equal magnitude but opposite polarity, comparator H for comparing the integrator output with a sawtooth reference S and means for selecting one of the pair of signals according to whether the sawtooth or integrator output is the greater. The device has two resistances, a variable Rt and a standard Rs supplied with the same current and the analogue voltage is the difference between the voltages across the resistors and the pair of voltages are the voltage across Rs. The digital output is derived from the difference in duration of the two states of comparator H. The current through resistors Rt and Rs is supplied from battery E. The junction of Rt and Rs is earthed. The voltage e t  across Rt is inverted and supplied via R 3  to the integrator and the voltage e s  across R s  is similarly applied via R 4  so that it opposes e t . The resulting voltage -(e t -e s ) is supplimented by e s  via two way switch K and resistor R 5 . The integrator output takes the form of E 10  with a change of gradient from negative to positive each time it crosses the sawtooth. The comparator output has the mark space square waveform E7 and the resistance difference is proportional to t x . If Rs is temperature sensitive and Rs = Rt when T = 0 C., the device can be used to give a direct reading of temperature.

Abstract: 1,170,586. Data processors; symbolic addresses. GENERAL ELECTRIC CO. 16 Nov., 1966 [16 Nov., 1965], No. 51390/66. Heading G4A. Symbolic address signals from data processing unit to data storage units are converted to absolute addresses by an address translator circuit including a decoding circuit and an encoding circuit having a predetermined encoding function connected to said decoding circuit. A plurality of data processors (including one exclusively for controlling transfers between peripheral devices and main memory) and a plurality of storage units may be provided together with known priority interrupt circuits for multiprogramming as indicated schematically in Fig. 1 (not shown). In the translator circuit (Fig. 2), coded signals DLP 0-4 representing programme numbers and coded signals DLB 0-4 representing symbolic storage block numbers (one block corresponding to 1024 word storage locations) are decoded by means of decoders 350 and 351 and a decoder matrix 352 into a signal on one only of 1024 output lines. This signal after passing through clocked gates 356, enters encoder matrix 355 whereby absolute address signals MACJ-MACN, MACT, MACV and MAB 0-MAB 4 are generated, signal MAB 5 being an interrupt sequent signal and MAB 6 a micro control signal. The absolute address signals thus generated may be stored in a portion of a register 40 for future direct reference. The part of a symbolic address relating to word locations within a storage block is not translated but used in unaltered form. A complete symbolic address comprises a 5-bit programme number code, a 5-bit symbolic block address and a 10-bit symbolic word address, the absolute address generated comprising a 5-bit block address and the 10-bit word address. The decoders and encoder of the translator circuit may be of any known kind including plugboard types and read/write memories and means may be provided for switching from one network to another. Alternatively an associated store may be used. Programmes may be assigned coded numbers appropriate to their priority and storage space required by a supervisory programme. Fig. 7 shows the way in which two programmes PN-11 and PN-12 each with common consecutive symbolic block numbers may be allocated non-consecutive blocks in a number of different storage units including a fast access read-write store J, conventional read-write stores N+T and a read-only store M. The memories may comprise magnetic capacitive read-only memories or conventional magnetic core memories or combinations of these. Common portions of different subject programmes may be stored in the read-only stores. A data word comprises 24-bits. As well as the storage units having varying characteristics, the data processors may also vary as to speed and capability. The memories may feed back information to the address translator, e.g. indicating when they are full.
