Title: Compositions containing 1,2 Propylene Glycol Monoester
IPC: A21D2/16
Filed: 1966-06-24
Abstract: 1,153,623. Stabilized 1,2-propylene glycol monoesters. NATIONAL DAIRY PRODUCTS CORP. 24 June, 1966 [28 June, 1965], No. 28410/66. Heading C2C. [Also in Division A2] The invention provides a substantially diglyceride and triglyceride free composition comprising a 1,2-propylene glycol monoester of a fatty acid containing 12 or more carbon atoms, the monoester being predominantly in the alpha form, and an ionic surface active salt stabilizer having a hydrophilic-lyophilic balance of at least 16 which is dispersible in the monoester and, in the form of its alkali salts, in water and which forms an interfacial complex with the monoester, the concentration of the stabilizer not being so high as to form a crystalline phase in the composition. These compositions, in which the monoester is stabilized in the alpha form, are used as emulsifiers and stabilizers for foodstuffs, the alpha form being preferred for its whip-imparting properties and higher emulsifying power. The preferred monoester is glycol monostearate. The composition may also include monoglycerides derived from fatty acids containing 12 or more carbon atoms. The stabilizers are characterized as including groups which are hydrogen bonding in type or act as acceptors for hydrogen bonds and may be used in amounts of 1-25% by weight of the propylene glycol monoester. Specified classes of stabilizers include (a) alkali metal and alkaline earth metal salts of C 2-6  mono-, di- or tri-carboxylic acids substituted by ester or amide groups derived from C 12-22  fatty acids, e.g. K stearoyl lactate, K stearoyl hydroxy acetic acid; (b) Na salts of an acidic half ester of a glycerol monoester of a fatty acid and a dibasic acid, e.g. Na salt of monostearin succinic acid half ester; (c) salts of acylated amino acids, e.g., Na salt of stearoyl-N-glycine, K salt of palmitoyl-N-alanine; (d) salts of half esters of dibasic acids and fatty alcohols, e.g. mono stearyl fumarate Na salt, Na salt of sulphated lauryl alcohol; (e) cationic stabilizers, e.g. the hydrochloride of stearyl glycinate. Other stabilizers which can be in compositions which are not to be used in foodstuffs include Na salts of sulfosuccinic esters and quaternary ammonium salts. The compositions can be prepared by blending the components, e.g., by melting or by dispersing in aqueous media. The formation of the required interfacial complex can be ascertained from X-ray diffraction and IR analysis and the whipability of the composition. Examples relate to the preparation of glycol monoester compositions and the use thereof in food mixes (see Division A2).

Title: Improvements in or relating to electromagnetic vibratory equipment
Inventor: NICHOLAS BRYAN ANTHONY
IPC: G05D7/06
Filed: 1963-07-18
Abstract: 1,005,414. Converting. GENERAL ELECTRIC CO. Ltd. July 8, 1964 [July 18, 1963], No. 28457/63. Addition to 904,248. Heading H2F. [Also in Division G3] Electromagnetic vibratory equipment, e.g. a conveyer or screen, of the type disclosed in Specification 904,248 is provided with means for automatic retroactive control of the amount of material fed by the equipment. Specification 904,248 discloses a vibratory equipment which is vibrated by pulses derived from an A.C. source through a silicon controlled rectifier. In the present invention a vibrator 1 which is supplied through an S.C.R7 oscillates a resiliently mounted trough 3 which feeds material to a belt 2. A weight detector 8 and belt speed detector 12 provide signals which when multiplied in an integrator 9 give a signal indicative of the total output. This is compared with a desired feed-rate signal at 13 providing a D.C. error signal to a trigger control unit 11. The error signal is fed through an auto/manual switch to a trigger circuit 18 providing phase control of the S.C.R7. The circuit 18 (Fig. 2, not shown) comprises a sawtooth generator synchronized with the A.C. supply, this saw-tooth waveform being added to the D.C. error signal to initiate, at a given level, a train of high frequency triggering pulses from a blocking oscillator. The firing instant of the S.C.R7 is thus controlled to vary the amplitude of the pulses to the vibrator to maintain the amount of material constant. With a constant speed belt the detector 12 may be dispensed with. An overload protection device 16 and a surge suppressor 15 may be provided for the rectifier 7.

Abstract: 654,505. Automatic exchange systems. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd. Nov. 6, 1948, No. 28896. [Class 40 (iv)] In a system for use in a ship where the cabins are grouped together, e.g. by decks, and each group is provided with a service pantry, the dialling of a particular number, e.g. 9, from any cabin obtains access to the appropriate pantry. In response to this number, the group selector seizes a relay set which provides a feed bridge and has an associated switch PFS. An allotter switch AD started by relay ST connects with the seized relay set and relay GA energizes. Relay D follows, and the switch PFS hunts for an idle pantry line associated with the group containing the calling line, a marking being applied over wire M, 9th level contacts of the group selector and contacts in the calling line and pantry line circuits to bank PFS 5. If no such line is found, FT energizes in the last position of the switch and connects up BT, which applies busy tone, and H, which frees the allotter. If an idle line is found, FT energizes and makes the usual test circuit for H to guard against a double connection. Relay H switches through and ringing takes place in the customary manner. When the calling party clears, BT operates momentarily and removes earth from the P wire to release the group selector, after which earth is replaced until the switch PFS restores in response to clearing by the called party.
