Title: Fermented milk products
IPC: A23C9/127
Filed: 1955-06-06
Abstract: A yoghurt-like product is made by inoculation of whole or skimmed milk with yoghurt lactic acid bacteria and a Saccharomyces yeast to produce alcohol and the requisite aroma and flavour, adding a mucilaginous substance, e.g. agar-agar or methyl cellulose, and fruit juice, slices or pulp, adjusting the pH to 5.0-5.5, adding unfermented milk, pasteurizing the mixture by heating, and, after cooling, inoculating again with yoghurt lactic acid bacteria. Sucrose amounting to 3-5 of the milk may be incorporated.  The lactic acid bacteria are Lactobacillus p  bulgaricus, L. acidophilus, Streptococcus lactis and Streptococcus thermophilus.  The yeast may be Saccharomyces fragilis, S. cerevisiae, S. ellipsoideus, S. elegans or S. cartilaginosus.  Fruits referred to are citrus fruits, strawberries, peaches, bananas, apples, grapes, pineapples and tomatoes.  According to an example, 1 kg. of skim milk inoculated with a culture of Saccharomyces fragilis and Lactobacillus bulgaricus is allowed to ferment at 30-35 DEG  C. for 12-24 hours until 1.6 per cent of lactic acid and 0.4 per cent of alcohol have been produced; sucrose, methyl cellulose and condensed orange juice are added, sufficient calcium carbonate to produce pH 5-5.5 is mixed in, and 120 g. of skim milk are added; the mixture is pasteurized at 75 DEG  C. and cooled rapidly, inoculated with a culture of Lactobacillus bulgaricus and poured into small containers; fermentation is allowed to proceed at 37 DEG  C. for about 5 hours, until the contents of the containers jellify and 0.6-0.7 per cent of lactic acid is formed, whereupon the containers are placed in a refrigerator.

Title: Improvements in or relating to telemetering apparatus
Inventor: LEWIS GEORGE ANDREW
IPC: G08C15/12
Filed: 1951-07-12
Abstract: 685,903. Electric selective signalling systems. SHORT BROS. & HARLAND, Ltd. July 12, 1951. No. 16550/51. Class 40 (i). The invention relates to a telemetering system wherein the time intervals between successive pulses of a cyclic train are indicative of magnitudes of successive voltages, a synchronizing pulse, being sent at the end of each pulse train. The transmitter (Fig. 1) comprises a series of single stroke multivibrators VIa, VIb &c., followed by a master multivibrator V6e, V6f. The latter is free-running, but the individual multivibrators are normally conducting on the b valve only, each a valve being fed with a voltage via terminals 1, 2, &c, determined by the readings of individual meters, except for the last V5a which is fed with a known, large voltage via terminal K. At the beginning of the scan a positive pulse is sent to the grid of valve Via from the master multivibrator, which together with the meter voltage at 1 causes V1a to conduct for a time determined by the meter voltage at 1 and the time constant of the anode circuit. When the first stage multivibrator reverts to its initial condition a pulse is sent to the second stage multivibrator V2a, V2b to make V2a conduct. Thus all the multivibrators are triggered in succession, producing a series of pulses in the common cathode line 10, the time interval between successive pulses being dependent on the magnitude of' the signal volts applied to each stage. The pulses are fed to a further circuit Fig. 2 (not shown). wherein they are clipped and amplified, and fed to the modulating circuit of a radio transmitter. The receiver (Fig. 3) comprises a tuned receiver (not shown) followed by a number of valve stages 40-42e, where the pulses are cleaned and amplified, to be fed to a multivibrator comprising valves 43a, 43b for widening the pulses, followed by a gate valve 44 controlling the amplitude of a saw tooth wave in accordance with the time duration between successive pulses. These amplitudes may be shown on an oscilloscope via terminal B. The large synchronizing pulse at the end of each scan is picked out by a suitably biased valve 45b, amplified and used to synchronize the oscilloscope display. The received pulses may alternatively be connected to a synchronous electronic distributer as described in Specification 660,270, wherein they may be routed to a series of voltmeters or servo-motors for operating required controls.
