Patent GB-1298223-A (GB)
Title: Collagen products
Inventor: CHVAPIL MILOS
IPC: A61L15/40
Filed: 1969-11-27
Abstract: 1298223 Paper M CHYAPIL 27 Nov 1969 [27 Nov 1968] 58167/69 Heading D2B An absorbent collagen network is made by forming a suspension of comminuted untanned collagen tissue, homogenizing the slurry, including a non-collagenous cross-linking agent, adjusting the pH to less than 5.5 unless it is already below 5.5, freezing the slurry, holding it frozen for from 12 hours to 30 days, thawing the frozen slurry and squeezing out most of the water, e.g. in the nip of a pair of rolls. The cross-linking agent may be a tanning agent, e.g. glutaraldehyde, or may be a melamine-formaldehyde resin. The extent of the cross-linking can be controlled by varying the temperature and duration of the freezing to obtain a felt-like or spongy product. A plasticizer, e.g. glycerin or sorbitol may be included in the slurry. A textile reinforcement may be inserted in the slurry before freezing, or the porosity may be increased by beating in air or an inert gas, or by including a gas-generating substance such as sodium bicarbonate. The product may subsequently be sterilized for surgical use, or an antibiotic, analgesic, disinfectant or material that inhibits or promotes blood clotting may be included. Antibiotics used in an example are bacitracin, neomycin and tetracyclin. Sterilization may be by radiation from a cobalt-60 source or by means of ethylene oxide gas.

Title: Automatic frequency controlled oscillator circuits
IPC: H03L7/181
Filed: 1972-12-20
Abstract: 1409290 Automatic frequency control; gating Circuits SIEMENS AG 20 Dec 1972 [22 Dec 1971] 58834/72 Headings H3A and H3P An a.f.c. system for an oscillator 1, Fig. 3, comprises a first counter 4 to which the oscillator output is fed via a gating circuit 3 that may be enabled by a control pulse of a predetermined duration P applied to a first control input B or by a pulse K derived from the output of the counter applied to a second control input C, the output from gating circuit also passing to a second forward/backward counter 6 to advance its count if pulse K arrives during pulse P or to subtract from its count until the arrival of pulse K if pulse P terminates before the arrival of pulse K, the final count in counter 6 being applied to a D/A converter 7 to form the control voltage for oscillator 1. Arrival of the leading edge of pulse P enables output Z<SP>1</SP> of the gating circuit to pass the oscillator output to the counter 4. The count is compared with a reference count in comparator 19 to produce the output pulse K when the two are equal. If pulse P ends before the arrival of pulse K, output R<SP>1</SP> is enabled by the end of pulse P, and remains enabled until the arrival of pulse K. If pulse K arrives before the end of pulse P, output V<SP>1</SP> is enabled by pulse K and remains enabled until the arrival of pulse P. The comparator 19 also provides a coarse frequency control via D/A converter 20. In a modification, Fig. 1 (not shown) the signal K is produced directly by counter 4 filling up. Gating circuit, Fig. 2.-Arrival of a P pulse enables gate 15, to pass the signal at A to output Z<SP>1</SP>. If the P pulse terminates before the arrival of a K pulse, the trailing edge of it sets bi-stable 9 to give a "1" on its Q output to hold gate open, and provide inputs to bi-stable 11 such that it sets to enable gate 14 to pass the signal at A to output R<SP>1</SP>. Subsequent arrival of a K pulse resets bi-stable 9 inhibiting gate 15 and causing bi-stable 11 to reset inhibiting gate 14. If a K pulse arrives before the P pulse terminates, it causes bi-stables 10, 12 to set enabling gate 13 to pass the signal at A to output V<SP>1</SP>. Subsequent arrival of the end of the P pulse then inhibits gate 15 and causes bi-stables 10, 12 to reset inhibiting gate 13.

Patent GB-2021887-A (GB)
Title: Radio receiver channel selector
IPC: H03J5/02
Filed: 1979-05-18
Abstract: A frequency selector and tuning means for a radio or TV includes a keyboard input to receive a code from a user and a processor for calculating an address from the code and also for incrementing a signal applied to a phased locked loop. Once the station has been found, the incremented signal, which is a division ratio fed to a programmable divider which applies an output signal to a phase comparator of the phased locked loop, is stored in a random access memory at a location designated by the address calculated by the processor. A search mode allows a user to locate all stations and store, in the above described manner, division ratios in the memory which may be used to tune to that station later. To tune a particular station, the user keys in the code he has selected. The processor calculates the address and retrieves the division ratio from the memory. This division ratio is fed to the programmable divider to cause the frequency synthesiser to tune to the station represented by the code.
