Title: Refrigeration compressor
IPC: F04B27/10
Filed: 1972-10-04
Abstract: 1412776 Compressors JOHN E MITCHELL CO 4 Oct 1972 45788/72 Heading FIN In a reciprocating compressor some of the oilentrained refrigerant gas entering suction chambers 16A blows past the compressor pistons 26 into a sump 20, the difference in pressure between the sump 20 and the suction chamber 16A causes oil collected in the sump 20 to flow through lubricating flow paths back into the suction chambers 16A. The pistons 26 are reciprocated by connecting rods connected to a plate 24 which is caused to wobble around a bevel gear 34 by a rotor 22. The oil and refrigerant is sucked into the chambers 16A through rotor bearings 46, 50 and spaces 44, 48 into a cavity 40 surrounding a shaft 36 for driving the motor 22 and thence by passages 56, 58. A passage (60) having a calibrated orifice (60A) extends between the sump 20 and the chambers 16A to prevent an excessive amount of oil from collecting in the sump 20.

Title: Improvements in or relating to press control systems
Inventor: BEARD JACK HERBERT
IPC: B30B15/24
Filed: 1962-12-04
Abstract: 1,039,517. Forging presses. DAVY & UNITED ENGINEERING CO. Ltd. Oct. 30, 1963 [Dec. 4, 1962], No. 45794/62. Heading B3H. [Also in Division B5] In a forging press the crossheads 11, 12, driven by main rams 13, 14 have control rams 16, 17 respectively. Sides 16A of rams 16 are connected to an hydraulic pump 18 via line 23, valve 22 and line 21. Sides 17B of rams 17 are connected by lines 27 and valve 22 to tank 20 when the crossheads are being closed, and to pump 18 when the crossheads are being withdrawn (see connections 39 and 37 in valve 22). Sides 16B of rams 16 are connected via line 24 valve 25 (in the position shown) and line 26 to sides 17A of rams 17, this " closed circuit " having a relief valve 29 and a one-way valve 30 connected to tank 20. If during closure crosshead 12 meets more resistance than the other crosshead and thus moves more slowly the fluid pressure in the " closed circuit " is increased which increase in 16B acts against the pressures 16A thus slowing crosshead 11. If crosshead 11 encounters more resistance then the pressure in the " closed circuit " is lowered and the speed of crosshead 12 consequently reduced. Symmetry about the forging axis 43 is thus maintained to some degree. If any excessive resistance is encountered by crosshead 11 or 12 then the rear cylinder of the other crosshead continues to urge that crosshead forward which causes in the case of continued movement of 11, an increase in pressure to the " closed circuit " resulting in a loss of fluid through valve 29, and in the case of continued movement of 12 a decrease of pressure causing more fluid to enter the " closed circuit " through valve 30, a consequent asymmetry of motion being produced in both cases. Pulse generators 40, 41 feed signals dependant upon the distance of crossheads 11, 12 from the forging axis into a difference detector 42 which when the asymmetry exceeds a certain degree sends out a signal which cause the valve 22 to be operated to initiate the return stroke of the press. The first crosshead to reach its outer position actuates either switch 31 or 32 which operates solenoid 33 to move valve 25 to connection position 35, thus allowing either the excess fluid in the " closed circuit " to drain off, or more fluid to be introduced (depending upon which crosshead encountered excessive resistance), thus allowing the other crosshead to reach its outer position. The other crosshead actuates the other of switches 31, 32 and moves the valve 25 back to its original position and overrides the signal from the difference detector 42 so that a new stroke may be initiated.

Apparatus for removing sludge 30 from a bed 11 comprises a carriage mounted to traverse a supporting structure movable lengthwise on the walls of the bed. The carriage has a slat elevator 21 running in an open-bottomed vertical casing 18 which has a sludge-digging member 29 mounted on the bottom which can be pivoted to operate in either direction of carriage movement. The slat conveyer is reversible and discharges on to one of two crossconveyers 28 which take the sludge to a conveyer on the supporting structure for discharge beyond the side of the bed. In operation, as the digger 29 reaches a side wall a limit switch stops the carriage, the easing raising motor is started to raise the casing 18 and by a suitable linkage reverse the digger 29, then the casing is lowered after the apparatus has been moved lengthwise of the bed and the carriage and elevator are re-started in the reverse direction. In a modification the whole elevator assembly is mounted on a turn-table on the carriage.

The initial aqueous solution may be a recycled portion of the NH 4 SCN solution made up, as necessary, with dissolved O 2 . Additional O 2  may be supplied to the gas/liquid contact zone. Thermal decomposition of the NH 4 SCN may be effected by spraying the solution into a chamber where oil or fuel gas is burnt with air, the air : fuel ratio preferably being adjusted so as to minimize SO 2  formation. A fluidized bed arrangement may be used. A suitable catalyst for decomposition of HCN in the resulting gas comprises one or more sulphides of Fe, Ni, Co, Mo, V, Th or U. Free S and SO 2  may also be removed in the same catalytic zone provided the gas stream contains enough H 2  to hydrogenate to H 2 S. The H 2  may be added, or obtained by operating the combustion/NH 4 SCN decomposition zone so that a CO/H 2 O shift reaction occurs. NH 3  and H 2 S are removed from the residual gas by conventional means.

Abstract: 1277671 Differentiating measured variables BP CHEMICALS Ltd 27 Oct 1970 [30 Sept 1969] 47936/69 Heading G4H A circuit for differentiating a measured variable such as photo-electron current i with respect to a retarding voltage v in a photoelectron spectrometer comprises circuits A, B, D, E for producing the voltage v which increases with time, a detector M for measuring the current i, a voltage to frequency converter L and a counter J which adds the pulses received from the converter L during one clock pulse from the source A and subtracts from the total the pulses received during the next clock pulse. Switches in a control circuit C are manually preset to determine the rate of increase of the voltage v which is supplied as one input to an X-Y recorder G via the digital to analogue converter E. A frequency divider K which is also connected to the circuit C provides an output the frequency of which is proportional to the measured current i and which is differentiated with respect to time by the counter J. Since the voltage v increases linearly with time the output of the counter J is also proportional to #i/#v which is fed via a store I and a digital to analogue converter H to the other input of the X-Y recorder.

Abstract: 1428699 Address-code multiplexing LICENTIA PATENT - VERWALTUNGS GmbH 22 Oct 1973 [26 Oct 1972] 49057/73 Heading H4P Instead of combining the address codes each representing an information bit of different transmitters to give a multiamplitude signal, they are mod-2 added so that the multiplex signal is still binary. A multiamplitude signal may however be reconstructed at the receiver to permit normal correlation techniques to be used for channel identification. Each transmitter (S, Fig. 1, not shown) sends its address code Xk, Fig. 2, to represent one information bit. This is first transformed to a differential code signal Yk in which a level change represents a 1 in the address, Xk. This is mod-2 added at 5 to the composite signal #Yi from other transmitters to give a multiplex signal M for transmission. At the receiver, the signal M is differentiated and the result rectified at 7 to give a pulse train T. A pulse train Xkd corresponding to the address (Xk or Yk) of transmitter S is compared with pulse train T (by means not shown) to detect the presence of a transmission from S. Alternatively a multiamplitude signal #Si is constructed at the receiver by using each pulse T to generate a clock-period-length pulse S 1 , S 2  &c. and adding these; this is done with a delay (9) and an integrator (8). A correlator (10) then detects if the S transmission is present in #Si.
