Title: Method and a decision unit for analysing polyphase psk or am-psk signals
IPC: H04L27/38
Filed: 1976-03-25
Abstract: 1530417 Data transmission; polyphase PSK or AMPSK systems CSELT CENTRO STUDI E LABORATORI TELECOMUNICAZIONI SpA 25 March 1976 [27 March 1975] 11943/78 Heading H4P In the demodulation of a polyphase PSK or AMPSK signal transmitted over in-phase and phase-quadrature channels and in which there are sets of optimal zones in the quadrants for recognizing a signal, the zone and the quadrant are determined separately. Analogue phase (quadrature) signals from conventional demodulators are a/d converted in AD1 (AD2) into seven bit modulus words plus a sign bit representing the binary value of signal samples. The seven modulus bits are reduced in AR1 (AR2) to six bit words which are decoded by DEX (DEY) in which address rows and columns of ROM1 comprising a matrix of 64 x 64 cells each storing a 2 bit word, read when a clock signal CK is applied. This identifies one of 3 optimal zones (see Fig. 4, not shown) but not which quadrant. Output from ROM I is led to a decoder SN2 which together with decoder SN1 receiving sign information from AD1, AD2 address columns and rows in a 4 x 4 cell ROM2. Each cell contains 3 bit words defining the relevant optimal zone which appear on line 8, also in a feedback receiver m bit words, representing e.g. sine and cosine, which appear on lines 9, 10. The two memory structure is stated to allow reduction in memory capacity, a change in sync. system geometry necessitating only a change in ROM 1 and a change in angular functions a change of ROM2. ROM's 1, 2 may be replaced by read/write memories.

Title: Process for extracting glycerine from distillery residual liquors
IPC: C11D19/00
Filed: 1937-04-27
Abstract: In a process for the recovery of glycerine from the residual liquor from the distillation of fermented must, flocculation of suspended and colloidal matter is effected by neutralizing with lime and adding ferrous and aluminium sulphates, the clarified liquor is separated by decanting and filtering, freed from calcium salts, e.g. by adding sodium carbonate and ferrous sulphate (which causes flocculation of suspended calcium carbonate), and concentrated, and the sodium and potassium salts which crystallize are removed; the resulting liquor may be further purified or distilled, e.g. under reduced pressure.  A small quantity, e.g. 5-10 per cent, of the filtered residue from the treatment of another batch may be added to the crude liquor in order to improve the flocculation; part of the clarified liquor may be used for the preparation of musts, the repeated re-circulation increasing the concentration of the clarified liquor which is to be treated for removal of calcium; the clarified liquor may be partially concentrated before treatment for removal of calcium salts; and the concentration of the purified liquor may be effected in multiple or single-effect apparatus under pressure, the first or the single compartment of the evaporator being heated by the main steam supply and the alcohol distillation column being heated by the steam formed by the evaporation.ALSO:In a process for the recovery of glycerine, in which the residues from the distillation of fermented must are treated with lime, ferrous sulphate, and aluminium sulphate, and the clarified liquor is treated for removal of calcium salts before concentration, part of the clarified liquor is used for the preparation of musts, the repeated re-circulation increasing the concentration of the clarified liquor which is to be treated for removal of calcium.

Title: Data analyzer
IPC: G06F7/38
Filed: 1976-03-25
Abstract: 1507776 Data processing MATEMATIKI I MEKHANIKI AKAD NAUK KAZAKHSKOI SSR 25 March 1976 [25 March 1975] 12005/76 Heading G4A During addition (or subtraction using complemented addition) of two operands each represented by the remainders when the operand is divided by a plurality of relatively prime bases the sign of the result and whether the result has overflowed (exceeded the range, equal to the product of the bases, of the number representation) are determined by a logical unit 17. The two operands are supplied at 3, 8 together with representations at 5, 10 of the values of the respective operands in a positional (e.g. decimal) notation, to number evenness formers 1, 6, which supply signals indicating whether the operands are odd or even. A third number evenness former 11 receives the algebriac sum of the two operands and the output of a circuit 14 generating the attribute representing the value of this sum in the positional notation. The signs of the two operands are supplied at 24, 25. If the two operands to be added have the same sign (determined by modulo two addition) logical unit 17 provides the same sign for the sum and calculates whether there is an overflow by taking the modulo two sum of the outputs of the evenness formers 1, 6 and 11; if the evenness of the sum, from 11, is equal to the modulo two sum of the operand evennesses from 1, 6 no overflow occurs, otherwise an overflow occurs, as the range is odd. If the two operands to be added have opposite signs (or same sign operands are subtracted) no overflow can occur. The addition is carried out by adding the complement to the range of the negative operand to the positive operand and it is determined whether this sum has overflowed; if it has the sum of the two operands is positive, otherwise negative, the result in the latter case being the complement to the range. The indication that the sum is negative may be used to complement the result.

Title: Machine for knotting the wire ends of upholstery springs with their end coils
IPC: B21F33/04
Filed: 1955-04-27
Abstract: 769,636. Coiling ends of springs. SPUEHL AKT.-GES. April 27, 1955 [July 3, 1954], No. 12107/55. Class 83 (4). A machine for knotting or winding the wire end of an upholstery spring around its end convolution by means of a knotting wheel having a radial slot for receiving the wire end and part of the end convolution is characterized in having a main shaft, driven by a clutch and carrying a driving wheel and cam discs for pivoting an arm carrying the knotting wheel into and out of engagement with the driving wheel, jaws for holding the spring, and a shaft, which may be coupled to a machine for winding the spring, having a cam disc controlling the clutch and the jaws. An upholstery spring P, Fig. 5, is inserted by conveyer mechanism of a spring winding machine (not shown) into open jaws 38, Fig. 4. A cam 44, on a shaft 40 coupled with the spring winding machine, operates a valve 43 to actuate in turn a valve 49 to supply compressed air to valve means 52 which, through a pipe-line 63 and rod 67 rock a lever 37 to close the jaws 3<SP>8</SP>. The rocking of the lever 37 operates a valve 70 of the valve means 52 to actuate a valve 72 to rock a lever 16 to allow a clutch element 12, keyed on a shaft 1, to engage a gear 9 rotating loosely on the shaft 1 so that the shaft 1 rotates. As the shaft 1 rotates, a cam 22 thereon rocks an arm 7 carrying a knotting or winding wheel 6 so that the wire end and the end convolution of the spring enter a slot in the knotting wheel. Continued movement of the arm 7 bends the wire end down and finally the knotting wheel 6 engages a driving wheel 5 on the shaft 1 and is rotated three times thereby to wind the wire end around the end coil of the spring. The jaws 38 are held closed by a ratchet disc 32 on the shaft 1 until a notch 33 is engaged by a projection 34 on the lever 37. The clutch 12 is disengaged by a cam 15 thereon. The slot in the knotting wheel 6 is aligned by a camoperated stop 28 engaging a recess 29 in a wheel 31 meshing with the knotting wheel. The machine may be actuated electrically, Fig. 9 (not shown), by the cam 44 on the shaft 40. In another arrangement, Figs. 10-16 (not shown), interconnected linkage means actuated electrically, pneumatically or hydraulically operate the lever 37, arm 7 and arm 16.

Title: Three position actuator
IPC: G05D23/12
Filed: 1962-03-29
Abstract: 928,978. Hydraulic apparatus; valves. GENERAL DYNAMICS CORPORATION. March 29, 1962 [April 5, 1961], No. 12140/62. Classes 69 (2) and 135. An hydraulic actuator for positioning a member 19, which may be connected to a valve, in three indexed positions, comprises a tubular cylinder 6 receiving a piston 12 carrying the actuator member 19 which extends through a slot 20 in the cylinder, one end face of the cylinder and both ends of the piston being open to first and second chambers adapted to be connected by ports 7, 10 to a source of fluid pressure, the arrangement being such that when fluid pressure is supplied to one port or the other, the piston and cylinder move to one or the other of their extreme positions and when fluid pressure is supplied to both ports the cylinder moves to an extreme position in one direction and the piston moves to an extreme position in the other direction wherein it engages an abutment 6a on the cylinder to determine an intermediate position of the member 19. The first and second chambers are formed in blocks 2, 3 mounted on a plate 1, the first chamber being formed by a cylindrical recess 4 which slidably receives the cylinder 6. The opposite end of the cylinder is received in an annular recess 5 in the member 3, the recess being vented by a passage 5a. The piston 12 slides in the cylinder 6 and its ends are exposed to fluid pressure supplied through the ports 7, 10. The movement of the piston to the left relative to the cylinder is determined by the abutment 6a which defines a port 6b. The abutment member is carried by the piston and is in the form of a pin which extends through a slot 20 in the cylinder and carries rollers 21 engaging a forked arm 22 on a shaft 23 which may be connected to the valve. When fluid pressure is supplied through the port 7, the piston 12 moves to the left and engages the abutment 6a to move the cylinder also to the left to define one extreme position of the member 19 and shaft 23. If fluid pressure is then supplied to both ports, the pressure acts on the left-hand end of the cylinder to move it to the right but the fluid pressure acting on the larger area of the piston at the right, because of the abutment 6a, returns the piston in engagement with the abutment, the movement of the cylinder being effective to move the pin 19 and rotate the shaft 23, say, 30 degrees. When fluid pressure is supplied to the port 10 only, the piston moves to its extreme right-hand position, the total rotation of the shaft from one extreme position to the other being 90 degrees.
