Title: Improved Process for Emulsifying Fats and Fatty Substances.
Inventor: SCHLINCK JULIUS
IPC: C09K23/00
Filed: 1916-03-27
Abstract: 104,933. Schlinck, J. March 27, 1916. Butter substitutes.-Small quantities of cholesterines or oxycholesterines are added to fats in order to facilitate the formation of emulsions with water or aqueous liquids, the permanence of the emulsions also being increased. The liquid employed may be milk or any aqueous liquids containing albumens, including casein in the dissolved or swelled condition, skimmed milk being particularly suitable, and the proportion of cholesterine to fat varying from 0.1 to 0.4 per cent. After this addition the fatty substance is treated with the aqueous liquid in emulsifying-apparatus of the known kind. An example of the proportions and steps in the process of emulsifying coconut butter with skimmed milk is given. By the use with skimmed-milk of mixtures of fats as neutral as possible and having a melting point between 26 and 36 C., for example cocoa fat and fats of higher melting-points, a product similar to cream or cow's milk is stated to be obtained, condensible after the addition of sugar with or without food salts to a uniform extract, the fat remaining in a state of fine sub-division. The Specification adverts to the state of prior knowledge respecting the emulsifying of sulphonation products of fats, &c., the emulsification of rubber and viscose with the aid of cholesterol, the promotion of emulsification by the addition of borax or cholesterines in small or large quantities respectively, the production of emulsions of fats in milk, and similarly of codliver oil containing 2 per cent of chloresterines, and of sesame or poppy oils. Reference is made also to proposals for adding an ether-alcohol solution of cholesterine to milk in producing an aromatic fermented milk for the manufacture of margarine emulsion.

Title: Coin checking device for a vending machine

Filed: 1977-02-07
Abstract: 1523415 Checking coins NIPPON COINCO CO Ltd 7 Feb 1977 [10 Feb 1976] 04981/77 Heading G4V A coin checking device has two coin detectors 10 and 11 consisting of differential transformers. The secondary coils 2-5 produce waveshapes 2<SP>1</SP>-5<SP>1</SP> as shown in Fig. 2, which are applied in order to level detectors 12-17. Detectors 12, 13 detect the passage of a coin and produce from flip-flop 18 a pulse output as shown at Fig. 2(6). A window circuit 20 detects the high peak levels of the waveshapes for a particular denomination of coin through detectors 14, 15 which detect the H and L levels as shown. A waveshape trailing edge detection pulse generator 24 detects the output of NOR gate 23 as shown in Fig. 2(c) and produces a short pulse as shown in Fig. 2(d). Meanwhile waveshape trailing edge detection pulse generator 27 produces pulses P 1 -P 4  as shown in Fig. 2(c) which are applied to shift register 28. The outputs of stages 28-1-28-4 are as designated in Figs. 2(f)-2(i). The signal from stage 28-1 is applied to AND gate 26 whilst waveshape 3<SP>1</SP> is being produced. If this is satisfactory pulse generator also applies a signal to gate 26. The AND gate then produces a pulse as shown in Fig. 2(j). This pulse activates pulse counter 29 that produces a pulse as shown in Fig. 2(k). Similarly, pulse generator 31 is activated to give a pulse as shown in Fig. 2(m), AND gate 31 is then activated to denote a true coin when the coin has passed detectors 10 and 11, as determined by the output of stage 28-4. Inhibit circuit 32 is operative if a true signal for different denominations is simultaneously produced. In a modification each window circuit detects two set lower levels, Figs. 4 and 5 (not shown).

Abstract: The reaction of 1-amino-2-phenoxy- or 1-amino-2-methoxy-4-hydroxyanthraquinone with the appropriate primary alcohols in the presence of polyethylene glycols which have a molecular weight of above 150 leads to 1-amino-2-alkoxy-4-hydroxyanthraquinones which carry a linear or branched alkyl in the alkoxy groups and in which the alkyl can additionally be further substituted. The process makes possible short reaction times and virtually complete reactions with those alcohols which react only incompletely or only very slowly under the conditions of the prior art. The process products are red to pink dyestuffs for synthetic fibres.

Abstract: 931,528. Casting composite articles. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Feb. 9, 1962 [Feb. 10, 1961], No. 5124/61. Class 83 (1). An electrical switch contact comprises a metal body cast directly on to a refractory metal tip in a vacuum. A molybdenum or tungsten tip 21 is located within a graphite container 1 by a graphite ring 22 beneath a graphite two-piece mould 5, 6 located within the container by pins 11. The space above the mould forms a reservoir for molten copper 24 which flows into the mould through a gate 8. The upper part of the container is surrounded by a polished molybdenum sheet 16 which together with the greater thickness of the wall portion 15 reduces heat loss therefrom so that the copper solidifies from the bottom of the mould upwardly. When an alloy of copper and 0.6% Cr is used for the contact body, those parts of the mould which come into contact with it are made of pyrophyllite. Solid copper is placed in the container which is then placed in a vacuum in a radiation or induction furnace to melt the copper. In a modification the molten copper from the reservoir 12 flows through feed holes in a graphite plate to mould cavities in a lower graphite block in each of which cavities a tip is located. After casting each contact body is detached by breaking the small neck extending through the corresponding feed hole.
