Title: Sterile articles for the surgical repair or replacement of living tissue
IPC: A61F2/06
Filed: 1964-10-02
Abstract: Sterile articles for the surgical repair or replacement of living tissue, absorbable by living tissue, are formed from polyhydroxyacetic ester (also known as polyglycolide or polyglycolic acid).  One aspect of the invention relates to sterile surgical sutures having from 1 to 4, 000 dernier and made from solid, stretched and oriented polyhydroxyacetic ester.  The ester in monofilament or polyfilament form may be attached to a surgical needle and then enclosed in a sterile package, e.g. transparent polyester-polyethylene packets, and sterlized by ethylene oxide permeating the seal line.  Other substances may be present, e.g. dyes, antibiotics, antiseptics, anaesthetics and antioxidants, and the surfaces of the fibre can be coated with a silicone or beeswax. The polyhydroxyacetic estor may also be formed into tubes or sheets for surgical repair and may also be spun as thin filaments and woven or felted to form absorbable sponge or gauze.ALSO:Polyhydroxyacetic ester is spun as thin filaments and woven or felted to form sponges or gauge which are absorbable by living tissue and used for surgical repair.

Abstract: 1,160,684. Radio receivers. E. MORICI, and C. ZIMATORE. 14 Sept., 1966 [l4 Jan., 1966], No. 40995/66. Heading H3Q. An automatic tuning arrangement for a radio receiver comprises a frequency discriminator fed from the receiver and controlling a bi-stable circuit; in one state of the bi-stable circuit a capacitor is charged continuously, the charge on the capacitor controlling electronic tuning means so that the receiver sweeps over a band, and in the other state the capacitor is isolated so that the receiver stays tuned to the same frequency. The output of the discriminator is such that the receiver sweeps until a signal is found, when the receiver is held to the frequency of the signal. When fully charged the capacitor may be discharged by a mono-stable circuit. The receiver may be provided with manually operated means for switching the bi-stable circuit to the sweep mode, and with a potentiometer to allow manual tuning. The tuning means may be coupled to indicating means.

Heading G2C The method of the parent Specification in which a layer comprising a dye, such as a dye sheet used for mechanical preparation of spirit printing sheets, is pressed against a gelatine silver halide emulsion layer bearing an image in silver and hardened gelatin to transfer emulsion from the non-hardened areas to the dye layer, and in some instances to transfer dye to the image areas of the emulsion layer, when both layers may be suitable for spirit printing, is modified by using an emulsion layer exhibiting lesser gelatin hardness in the silver image areas than other areas for the transfer. In an example a chloride emulsion on a paper sheet is reflex exposed to a document, treated in a specified metal-hydroquinone developer and then in an acidified cupric chloride-hydrogen peroxide solution, pressed on to a dye sheet which may be a duplicating carbon paper or a hectographic dye sheet, the sheets separated, and the original sheet used for spirit printing.

Title: Improvements relating to type casting machines for the printing trade
Inventor: WHITTAKER HAROLD PETER
IPC: B41B5/12
Filed: 1961-11-18
Abstract: 956,694. Type-bar making machines. M. H. WHITTAKER & SON Ltd. Nov. 19, 1962 [Nov. 18, 1961], No. 41346/61. Heading B6W. A type-casting machine is arranged for alternatively casting slugs when matrices are held in a clamping block 9 and continuous strip when, a strip mould is in use, the strip being drawn from the mould by the clamping block. A pot 1 for molten metal has a pump 2 actuated by an hydraulic cylinder B and carries a slug-ejector plate 3. The pot is reciprocated horizontally by an hydraulic cylinder A to move the pot outlet into and out of contact with one face of a mould in a rotatable mould wheel 4 rotated through 90 degrees in either direction by gearing 6 driven by an hydraulic cylinder C. The cylinder A also reciprocates the block 9 towards and away from the wheel 4. The block 9 has a setting stick 10 for casting slugs and a gripper 11, Fig. 2, operated by an hydrauilic cylinder D, Fig. 1, for strip-casting. In operation, when casting slugs the operator sets the matrices, not shown, in the stick 10. The pot 1 and block 9 are moved up to a mould in the wheel 4 and retained there while metal is pumped from the pot 1 into the mould. The plunger of pump 2 is then withdrawn by cylinder B. The wheel 4 is then turned by cylinder C. The pot is again advanced to eject the slug and then retracts to enable the mould wheel 4 to be returned. For casting continuous strip, wheel 4 is turned by a hand wheel 7, Fig. 2, to bring a strip mould into casting position and the pot 1 is advanced and locked in position by a lever 44, Fig. 3 (not shown). A dummy strip, not shown, is inserted in the block 9 with one end projecting into the mould. The gripper cylinder D, Fig. 2, causes the gripper 11 to grip the strip, metal is pumped into the mould and is cast on the end of the dummy strip which is drawn away from the mould by movement of the block 9 by actuation of cylinder A. At the end of the stroke, the gripper 11 is released and the pump plunger 2 is withdrawn. The block 9 is then advanced with the gripper 11 re-applied and the cycle repeated to produce the desired length of continuous strip. A spring-actuated gripper (not shown) may replace the gripper cylinder D. An electric or pneumatic control system may be used to control the sequence of operation of the machine.

Title: Memory device
IPC: G11C7/00
Filed: 1972-09-07
Abstract: 1406312 Data processors CASIO COMPUTER CO Ltd 7 Sept 1972 [11 Sept 1971] 41465/72 Heading G4A A shift register store, in which words of variable length can be written at a selected address, has its output connected directly or via an overflow shift register, as necessary, to the input of the main register. The overflow register output is disconnected from the main register at the start of each recirculation cycle. In the embodiment shown, a buffer register BR feeds data via an adder ADD to the main register SR1. The last stage Do of SRI feeds overflow register SR2. Feedback of data from stage Do of SR1 or from a stage D1-DN of SR2 is controlled by the count on counter RC. The main register SR1 is initially filled from unit M with a start code F and space codes S. Code F is taken as denoting the first address of a sequence of addresses each denoted by a code S. The register is thus filled with a circulating sequence SSS ... FS ... S. Read-in.-When a data word placed in the buffer register BR is to be stored in an address N in SR1, address counter ADC is set to N. When start code F reaches stage Do it is detected by unit MD and counter ADC is decremented by 1. Each subsequently occurring code S also decrements the counter until the counter reaches zero. During this process, counter RC being at 0, the output of stage Do has been fed back to the input of SR1 via ADD. If N=1, for example, code F will now be in the first stage of SR1. Successive digits of the word in BR are now read in to SR1. Since there was previously no data at the selected address, readin from BR will cause overflow of codes S to regisrer SR2, counter RC indicating which stage of SR2 contains the first S code to overflow. When register BR has been read in to SR1 recirculation takes place from the stage of SR2 indicated by RC. When code F again reaches Do counter RC is reset and feedback is again from Do, the overflow signals in SR2 being lost. Should a word d digits long be subsequently read in to an address lying between address N and start code F, the word at address N will be automaticatly shifted d stages further away from F, and d codes S will overflow and be lost. Read-out is non-destructive, the word from the required address appearing in BR. Addition takes place in a similar manner to read-in, the digits of the word in BR being added to the word at the selected address, digit by digit, as it is fed back from stage Do. If the addition results in a carry digit, overflow of an S code into SR2 occurs as described above.
