Title: Edible grainy caviar and process for producing same
Inventor: ROGOZHIN SERGEI VASILIEVICH
IPC: A23L17/30
Filed: 1984-05-09
Abstract: Edible grainy caviar comprising a shell of a gel-forming agent and a granule, the caviar containing the following components, per cent by mass: proteins                  3-25 gel-forming agent         0.5-4 vegetable oil             25-55 aminoacids                0.1-3 vitamins                  0.05-0.5 common salt               3-6 flavouring, odorant and dyeing agents             0.1-3 water             the balance. The granule contents are liquid and encapsulated in a transparent shell so that a major portion of the protein component in the granule is localized within a limited volume of the granule contacting with the shell thus forming a nucleus simulating a germ of natural caviar.   A process for producing the above-mentioned caviar comprises formation of granules by way of extrusive encapsulation in a device comprising two coaxially mounted tubes. An aqueous-protein suspension in a vegetable oil containing 3-25% by mass of the protein component is passed through the inner tube and an aqueous solution of a gel-forming agent containing 0.5-4% by mass of the gel- forming component is passed through the external tube. The resulting granules are dipped in a layer of a cooled oil, then separated, washed, dried and subjected to a culinary treatment.

Patent GB-2184657-A (GB)
Title: Hypodermic syringe
Inventor: MORLEY ROGER HUBERT
IPC: A61M5/50
Filed: 1985-12-19
Abstract: As shown in Figure 1, a pawl 30 is held displaced by a sleeve 34 located behind the piston 18. When the piston is retracted to draw liquid into the syringe the sleeve is displaced to the opposite end of the barrel where the pawl is then resiliently urged into the path of the piston. When the syringe is used to make an injection, the piston displaces the pawl to the inoperative condition as the piston passes the pawl, but then the pawl resiliently returns behind the piston, because the sleeve 34 is out of the way, and the pawl 30 then prevents the piston being withdrawn on a second occasion. This makes the syringe capable of use once only. <IMAGE>

Title: Optical transmission system
Inventor: GODDARD ISOBEL JENNIFER
IPC: H04B10/213
Filed: 1986-04-30
Abstract: An optical fibre transmission system has a large number (eg. 30) of nodes connected to an optical transmission line by passive couplers, there being at each node an incoming coupler and an outgoing coupler. If the adjacent nodes have adjacent frequencies, crosstalk is a problem. In the present system the allocation of frequencies to nodes is on a non-adjacent basis, preferably to a preset pattern. This reduces crosstalk between the channels formed by the various frequencies. In the system described the transmission line uses mono-mode optical fibre, and the frequency allocation to the nodes is as in the following table   <IMAGE>  and so on. When the odd-numbered frequencies have all been allocated, the even-numbered ones 2, 4, 6, 8... are used. <IMAGE>

Filed: 1986-06-10
Abstract: Three or more marine seismic sources (1-4) are positioned with critical inter-source spacing (D) to produce, when fired in the water, an acoustic pulse whose "primary to bubble ratio" for a given recording band width is substantially maximized. The sources of the array are adapted and positioned so that each produces when fired a bubble of substantially equal maximum radius (R). In one preferred embodiment, the array includes four sources positioned approximately at the vertices of a square having side length equal to  2ROOT 2 R, where R is the maximum radius of the bubble that would be produced by each source in the array if fired alone. In all embodiments, the critical spacing between each source and the source nearest thereto will be not less than 1.2 times the maximum bubble radius and not greater than the quantity 2R. In another embodiment, two or more sets of sources are employed, with the sources in each set being positioned and oriented in the water to produce when fired bubbles of substantially equal maximum radius, and such that each source in each set is separated from the other sources nearest thereto in the set by the critical spacing. <IMAGE>

Title: Theft alarm system
Inventor: MORGAN BARRY ALFRED
IPC: G08B13/14
Filed: 1987-08-26
Abstract: The alarm system is primarily for protecting valuables during transit, e.g. valuables carried in a briefcase, and comprises a transmitter and a receiver with the receiver including an alarm device and being attached to or associated with the valuables. The system is arranged to generate an alarm signal when the receiver is taken from the vicinity of the transmitter to an extent such that a predetermined signal transmitted by the transmitter fails to be detected at the receiver or when a substitute signal is received. The transmitter is operable such that the transmitted signal comprises a carrier signal modulated by a modulation signal which is determined or identified by the carrier signal. In the receiver (Figs. 2, 3 and 4, not shown) a reconstituted carrier is generated in a predetermined manner using the received modulation as a reference. If the receiver picks up a different transmitted signal which is incorrectly modulated, even if the relationship between the modulation frequency and the carrier frequency differs from the correct relationship by only a small amount, this is detected and the alarm activated. To increase security and save battery power the transmitter can be arranged such that the modulation signal is transmitted as a plurality of short bursts. A phase shift keying technique or a frequency shift keying technique (Figs. 5 and 6, not shown) may be used. <IMAGE>

Title: Continuous monitoring of electronic equipment
Inventor: COLTON MICHAEL WILLIAM
IPC: G06F11/00
Filed: 1987-11-12
Abstract: The apparatus includes various modules for testing specific types of equipment, e.g. AF circuitry, RF circuitry, etc.. In one example, an AF test module receives AF signals from the equipment under test into one of terminals SK1 or SK2. A test signal from a 1KHz source is applied to terminal 3. In order to test, for example, an AF amplifier, the 1KHz test signal is also applied to the input of the amplifier so that the apparatus effectively compares 53 the 1KHz test signal before entering the amplifier under test with that having passed through the amplifier. The circuitry tests both for amplitude variations outside a certain range, and for excess noise and/or distortion, and actuates a latched alarm when a fault is detected. Frequency reponse and RF tuner and receiver characteristics may also be monitored. <IMAGE>
