Abstract: 254,436. Whittaker & Co., Ltd., C., and Whittaker, N. April 24, 1925. Combined moulding and re-pressing machines; moulding; stationary-mould machines; heating. -In twin machines for combined moulding and re-pressing bricks the four upper pistons of the two moulds and two re-pressing machines are carried by a common crosshead, while the two lower pistons of the moulds are carried by a lower crosshead or drop bar; the lower pistons of the re-pressing machines being arranged to move upwards with the drop bar during the pressing' operation, but not to move downwards therewith for more than a predetermined distance. Thus the four upper pistons a, a<1>, b, b<1>, Fig. 4, are connected to the common crosshead C, Fig. 1, operated by mechanism (not shown) from the cam shaft G. The two lower mould pistons registering with the pistons a, a<1> are connected to the drop bar D operated directly by the cam G. The two lower re-pressing pistons b<2>, b<3> are carried by a bar E hung by rods e<1> from the upper crosshead. In operation the sliding carriage F delivers a charge to the moulding-machine at each stroke, and also pushes two moulded bricks into register with the re-pressing-machines, and delivers two pressed bricks. During the return stroke and the initial portion of the succeeding forward stroke of the carriage all four bricks are pressed and ejected, while during the latter part of the forward stroke the lower mould pistons are lowered to receive the fresh charge. The mould pistons are steam-heated, the steam being delivered to the piston b and following through all the other upper pistons in series as shown in Fig. 4. In the case of the lower pistons, the pairs of mould pistons and re-pressing pistons each receive a separate supply of steam.

Title: Variable resistance circuit
IPC: H03G3/00
Filed: 1976-03-17
Abstract: 1514136 Variable active resistance circuit YOKOGAWA ELECTRIC WORKS Ltd 17 March 1976 [31 March 1975 (2)] 10657/76 Headings H3T and H4R A variable resistance circuit comprises a terminal 1 connected to the drain (or source) of an FET Q; a differential amplifier A 3  whose output is connected to the gate of the FET and one input is a potential corresponding to that on the source (or drain) of the FET with the other input dependent both on the potential E 1  at the terminal I and on the multiplying constant of a multiplier F, and has a reference resistor R 0  connected between the source (or drain) and a common potential point 2. The equivalent variable resistance is usable between the terminals I and 2. The multiplier may have an analog controlling input 3 or be digitally controlled as in a ladder type d/a network (Fig. 2, not shown) which can be controlled by a counter (Fig. 3). Alternatively, the analog multiplier can be controlled by a pulsewidth modulated signal which is used to gate the input of a sample-hold circuit connected in negative feedback around an amplifier A2 (Fig. 6, not shown). In these embodiments the effective resistance varies linearly with the control function, by omitting the inverting amplifier A4 another set of embodiments having an inverse (hyperbolic) variation can be obtained with analog input (Fig. 7), digital i/p (Fig. 8), counter i/p (Fig. 9) and pulse width modulated input (Fig. 12). The FET Q can be used to control a junction transistor (T, Fig. 13, not shown) in Darlington connection to carry high signal currents between the terminals with the same type of controlling inputs (Figs. 13 to 16). The variable resistance can be connected to vary the gain in an operational amplifier arrangement (Fig. 17) with one (fixed) resistor (R) from output to inverting input of an amplifier (A) and the variable resistor from inverting input to common with the same types of controlling inputs (Fig. 17 to Fig. 20).

Patent GB-728749-A (GB)
Title: Improvements relating to the production of artificial filaments from proteins
IPC: D01F4/00
Filed: 1952-04-30
Abstract: Artificial filaments are obtained by spinning a solution of a globular water-insoluble protein containing at least one fatty substance consisting of an unsaturated triglyceride fatty oil (and/or free fatty acid derived from such oil) with one or more free or combined fatty acids having at least three and preferably four or more carbon to carbon double bonds in the molecule, the amount of fatty substance or substances used being not more than 5 per cent reckoned on the dry weight of protein and the addition being made during the formation of the spinning solution or after such formation but prior to spinning.  The fatty substance may be a fish oil or other type of marine animal oil.  The spinning solution may be an alkaline solution of a protein such as casein and it may be prepared and spun at a temperature below 50 DEG  C., e.g. 10-23 DEG  C.  The fatty substance may be emulsified in water and the emulsion may be added to an aqueous solution of caustic soda which is subsequently to be used to dissolve the protein. The protein solution may be spun into an acidic coagulating bath and the filaments so obtained may be passed through various hardening baths.  Fixation of the fatty material in the protein of the filaments takes place in the acidic spinning bath or in a subsequent bath.  In an example, lactic casein is moistened with water and dissolved in dilute caustic soda solution.  To this solution there is added an aqueous emulsion of bleached herring oil.  The temperature of the solution is maintained at 20 DEG  C. during all stages of its preparation and up to the time of spinning.  The solution is spun into an acid-salt spinning bath and the filaments are passed through an acid pickling bath and then hardened by passing them through one or more baths containing sodium chloride, aluminium sulphate, formaldehyde and acids. Specifications 719,319 and 723,215 and French Specification 813,427 are referred to.
