Title: Souffle mix
IPC: A23L1/00
Filed: 1961-04-18
Abstract: In a two-package mix for preparing a souffl<\>ae by the addition of a hydrating liquid and fresh egg, one package contains dried egg white and an improving agent therefor and the other package contains dried, pregelatinized starch, water-dispersible protein, a free-flowing fat powder and a minor proportion of a polysaccharide which has been hydrolysed sufficiently to allow diastatic enzymes to attack it in preference to the pregelatinized starch.  The egg white improving agent permits attainment of a fine foam which supports the souffl<\>ae ingredients, and is exemplified by an alkali metal phosphate, especially sodium hexametaphosphate triethyl citrate calcium stearate or palmitate. Cream of tartar may be incorporated in the first package.  The pregelatized starch may be pregelatinized potato tapioca maize, arrowroot, or sago starch or precooked wheat, oat, maize, or potato flour, pregelatinized potato starch being preferred.  The protein may be dried skim milk, sodium or calcium caseinate, casein soy or other legume protein.  The preferred fat powder is a dried emulsion of hydrogenated oil e.g. hydrogenated cottonseed oil containing fatty acid mono- and di-glycerides.  The hydrolyzed polysaccharide, exemplified by starch hydrolyzates of m.wt. 4300-7500, may be corn syrup of dextrose equivalent 24, potato syrup, a dextrin.  In making the souffle, the contents of the first package are stirred with water to a stiff foam, the contents of the second package are mixed with water and eggs and then with the flavouring material, to form a sauce, the foam is folded into the sauce, and the mixture is baked.  Flavourings referred to are sugar, fruit, vegetables, cocoa, chocolate, meat, fish and cheese.

Members 1, 2 of a low alloy steel containing 0.25-0.3% carbon, 1.5% manganese, 0.4% chromium, 0.2% nickel balance iron are preheated to 200-250‹ C. and layers 5, 6 are deposited from an electrode containing 0.06- 0.1 % carbon and an alloy content similar to that of the members with a slight increase in the chromium or nickel or an addition of molybdenum to compensate for the reduction in carbon. The layers 5, 6 having a carbon content higher than that of the electrode owing to dilution with the metal of the members 1, 2. Layers 7, 8 and if desired 9, 10 are deposited from an electrode having less than 0.13% carbon to produce a carbon content less than that of the layers 5, 6. The welds are stress relieved. The prepared members are welded by a deposit 17 similar to the layers 9, 10 after preheating to 100-125‹ C. which can be carried out on site. The layers are deposited on the members 1, 2 using retaining plates 13, 14 and spacers 11, 12.

Abstract: 825,822. Laying pipes. SULZER FRERES S. A. May 2, 1958 [March 22, 1958], No. 14141/58. Class 99(2). A lifting device, for use in joining heavy pipes comprises a retaining ring 51 clamped inside an already laid pipe 25, Fig. 1, and on which a vertically adjustable jib 28 is mounted which projects into and supports a pipe 22, Fig. 5, to be joined to the pipe 25. As shown, the ring 51 is part of a stiffening cage 50 described in Specification 825,824. Alternatively, the ring 51 forms part of the lifting device alone. The jib 28 consists of struts articulated to the retaining ring and to one another in the jib head on which a supporting roller 64 is mounted.

Title: Improvements in or relating to multichannel single sideband radio transmission systems
IPC: H04J1/00
Filed: 1952-06-06
Abstract: 696,356. Multiplex radio signalling. WESTERN ELECTRIC CO., Inc. June 6, 1952 [June 8, 1951], No. 14291/52. Class 40 (v). In a two-way multi-channel single side-band radio transmission system substantially the same range of frequencies is used for signalling in both directions, the two oppositely directed carriers being continuously transmitted during periods of operation with a frequency spacing sufficient to avoid interference therebetween. At the western terminal of the system the land lines 11 of subscribers A, B, C, D, are connected to the transmitter 12 and receiver 13 through a vodas 10, which when a signal comes in from a line disconnects the receiver from that line and connects the transmitter, similar apparatus being assumed at the eastern terminal. In the transmitter each channel has two stages of modulation, a first modulator 14 followed by a filter 15 which passes one of the side-bands, and a second modulator 16 followed by a filter 17 passing the desired side-band, the carrier being suppressed to the required degree. The oscillators 18 derive the frequencies fa, fb, fc and fd from a common stable oscillator 22, and the carrier oscillator 23 may derive the frequency f1 from the oscillator 22. The outputs of the filters 17 are combined in the amplifier 24. Incoming signals are applied to the amplifier 32 of the receiver 13 and thence to a common first detector 33, the resultant intermediate frequency being amplified at 34 and the channel side-bands being separated by filters 35. The original signal is recovered in each channel by a second detector 39 and applied to the land-line through a vodas 10. A filter 41 passes only the frequency f2 of the carrier which is applied to a frequency control circuit 42 to control the frequency of the oscillator 43, and to an automatic gain control circuit 45. The oscillators 46 derive their frequencies fa to fd from a stable oscillator 50. If the two carriers were of the same frequency the A.F.C. circuit 42 and A.G.C. circuit 45 would be affected by the locallytransmitted carrier, and to avoid this and at the same time use substantially the same bands of frequencies in both directions, the carrier frequencies are separated sufficiently to prevent the locally-transmitted carrier from drifting into the pass-band of the filter 41. Since the carriers are separated by only a few hundred cycles the audible note produced may be selected by a filter 51 tuned to the frequency f2 - #1 and applied to the oscillator 23 of the transmitter to maintain the frequency difference constant. Figs. 2, 3 and 4 (not shown), illustrate alternate arrangements for the frequency spacings of the two carriers and the side-bands.
