Title: Improved method of conditioning an edible fatty substance
IPC: A23G3/22

Abstract: 1,122,461. Tempering chocolate; coating with chocolate. J. W. GREER CO. 25 Oct., 1965 [29 Jan., 1965], No. 45018/65. Heading A2A. [Also in Division B1] A method of obtaining an edible fatty substance in a desired condition for coating (e.g. tempering chocolate) comprises (1) heating a molten fatty substance having meltable crystals therein, to. a first temperature to melt all the crystals, (2) simultaneously agitating and cooling the fatty substance to a second temperature at which the fatty substance contains at least the desirable crystals and (3) re-heating the fatty substance to melt any undesirable crystals during which heating additional desirable crystals are formed. In the case of chocolate the desirable crystals are the #-crystals and the undesirable crystals the #<SP>1</SP>-crystals and α-crystals. An apparatus for tempering chocolate and coating confectionery carried on an open meshed conveyer 14 with the tempered chocolate, comprises pump 42 for continuously transferring chocolate from tank 26 via water jacketed heat exchanger 46 to coaters 56, 58, the chocolate passing through conveyer 14 being returned to tank 26. Tank 26 is surrounded by enclosure 10 divided into 2 by a partition to form an endless circuit around which air heated by heaters 36, 38 is circulated by fan 32. The heat exchanger 46 is able to be connected via a valve 114, 118, or 120 to a different source of water at the appropriate temperature for each of the steps in the tempering process. When the tempered chocolate is produced the fluid passed via valve 116 through the heat exchanger 46 is cooler than that used in step (3) and this fluid is heated intermittently by heater 104 to maintain the chocolate at the temperature reached in step (3) while the coating process is carried out. Electrical control means are provided to connect the heat exchanger to the appropriate sources of water at the appropriate times and to switch on and off the heater 104 during the coating process. The apparatus may include a blower 90 for removing chocolate from conveyer belt 14, vibrator 84 and roll 80 for making details on the coated confectionery.

Title: Stabilising the response of a resonant filter
Inventor: REEVES ALEC HARLEY
IPC: H03M1/00
Filed: 1966-10-17
Abstract: 1,102,350. Analogue-to-digital converters. STANDARD TELEPHONES & CABLES Ltd. 17 Oct., 1966, No. 46296/66. Heading G4H. In a PCM system of the kind in which successive samples are applied to shock-excite a damped tuned circuit 2, Fig. 1, the number of oscillations above a given amplitude being a measure of the sample, the damping of the tuned circuit is controlled by a temperature-sensitive resistor, the output of the tuned circuit being applied to a stable reference circuit, the output of which decays at a fixed rate, this output being compared with the output of the tuned circuit and the difference being applied to the heater of the temperature-sensitive resistor to adjust the damping so that the output also decays at the fixed rate. The output of the tuned circuit is applied to an overload amplifier which limits the amplitude of the oscillating signal (a), Fig. 5, a low-level linearizer which imposes a linear law on the output of the amplifier. Bistable 5 acts as a threshold device producing pulses which, after differentiation and rectification, pass to counter 9. The value reached is transmitted serially. The signal (a) from the overload amplifier is applied to amplifier T1, Fig. 3, and passes via clipping diodes, which reduce the direct current component, to amplifier T2, passing only the positive part of the signal (b). This is applied to the comparator T4, T5 via an emitter follower, and through a peak voltmeter T3 acting as a peak storage circuit. The output (c) passes to a second peak voltmeter D4, the delay rate of which is faster than that of the first and gives the fixed value for comparison. The output signal of D4 is applied to comparator T4, T5, the initial parts of the signal being augmented by a circuit LLBC to produce signal (h). The difference signal (f) after further processing is passed to the heater of the temperature-sensitive resistor connected in the L-C circuit of the oscillator to bring the decay rate to the standard value as given by the peak voltmeter D4.

Abstract: 1,160,514. Centrifugal casting-machines. SHAHMOON INDUSTRIES Inc. 17 Oct., 1966 [23 Oct., 1965], No. 46400/66. Heading B3F. [Also in Division C3] In a centrifugal pipe-casting machine the pipe moulds 30. 40 are carried on shuttle cars 14, 16 that are moved individually or as a pair by hydraulic rams 118, 120 from a central pouring and core setting station 20, 18, to pulling and spraying stations 22, 24, 26, 28 where the cast pipe is pulled from the mould and the mould sprayed internally with a mixture of, for example, silica flour and bentonite suspended in water. The molten metal is poured from a holding ladle 54 into ladles 52 in measured quantities and then poured via rectractable boots 50 into the pipe moulds that are water cooled. The moulds rest in pairs between two spaced sets of spin wheels cornprising driven centre wheels 32, 33 and idler wheels 34, 35, 36, 37. The shuttle car carrying the charged moulds is then moved to a pulling and spraying station and the shuttle car carrying the empty moulds is moved to the pouring station. The pulling station comprises a pulling head (80), (Fig. 3, not shown), that is advanced hydraulically into the pipe, breaking the core in the process. An air cylinder (86) operates an expansion shoe (84) to grip the pipe and the pulling head is retracted pulling the pipe from the mould on to rollers (90) and on to inclined tracks 46, 48. The spraying station comprises lances 92 that are advanced hydraulically into the empty moulds to coat their insides. The lances are connected to a supply of coating material. The casting machine may be arranged so that there is a central pulling and spraying station and pouring stations are sited at the ends of the track 12.

Title: A process for purifying a lower alkyl ester of a phthalic acid
IPC: C07C69/80
Filed: 1963-11-26
Abstract: Alkyl esters of phthalic acids (containing 1-4 carbon atoms in the alkyl groups) which have been prepared by the oxidation of aromatic compounds not containing an a -tertiary carbon atom and, as a result, are contaminated with esters of formylbenzoic acid, are purified by treatment with molecular oxygen in the presence of a compound of chromium or/and a compound of nickel which is soluble in the reaction mixture, the treatment being followed by distillation.  The treatment with molecular oxygen may be effected at 140-300 DEG  C., preferably 200-280 DEG  C., under atmospheric, reduced or raised pressure.  The ester is preferably treated in the molten state, but a solvent may be present.  The proportion of iron compounds in the ester should not exceed 20 p.p.m.  The starting materials may be obtained by oxidizing xylene, toluic acid, tolyl aldehyde, methyl-benzyl chloride or ditolyethane with nitric acid, molecular oxygen or sulphur-ammonia and esterifying the product, which may be given a preliminary distillation. Examples are given of the purification of dimethyl terephthalate and dimethyl isophthalate, the naphthenates of chromium and nickel being used as catalysts.
