Patent GB-1014420-A (GB)
Title: Improvements in or relating to the testing of temperature
Inventor: JOHNSON CHRISTOPHER LINLEY
IPC: G01K11/22
Filed: 1963-11-07
Abstract: 1, 014, 420. Measuring temperature electrically. ROLLS-ROYCE Ltd. Nov. 7,1963, No. 44068/63. Heading G1N. Relates to a temperature determining transducer comprising a body which is set in vibration at a frequency which is modified by the temperature of a surrounding medium, and a sensing device which senses the frequency of vibration, and a means for comparing the frequency sensed with the frequency of vibration at a known temperature. The transducer 9 (Fig. 1) comprises a thin walled sealed cylinder 11 within a sealed outer casing 10. The casing 10 contains in space 14 a high thermal conductivity fluid e.g. hydrogen while cylinder 11 contains low conductivity fluid e.g. hydrogen/nitrogen. Within the cylinder 11 is a core 15 in which two magnets 16, 17 are disposed at 90 degrees to one another and carrying coils 18, 19 respectively. The electromagnet including coil 18 vibrates the cylinder 11 and the sensing device includes a permanent magnet 17 and coil 19. The two coils 18, 19 are connected across an amplifier such that a self sustaining vibration is induced in cylinder 11. The transducer is firstly operated at a known temperature To and a signal output S 0  is obtained from coil 19 which is taken as a reference, being proportional to the frequency of vibration at the known temperature. The transducer is then placed for example in the air stream of a gas turbine engine the temperature T of which is required, and the change of temperature acts through the walls of casing 10 to alter the pressure of the hydrogen. Thus the pressure difference across the walls of the cylinder 11 will vary, and also its frequency of vibration will vary. The difference between signal S obtained now from coil 19 and the reference signal S 0  will be proportional to the difference between temperatures T and T 0  In testing gas turbines, to obtain a value, directly, of #T the signals S, S 0  are combined by passing them through a heterodyne 25 (Fig. 2) and obtaining a beat frequency S b  which is proportional to #T. An oscillator 26 is provided which is adjusted to produce the reference signal S 0  identical with the natural resonant frequency of the transducer 9 before it is filled and sealed. Further a ratio of the speed of a compressor of the engine to the temperature i.e. N/#T is obtained by connecting a tachogenerator 28 to the compressor shaft, to provide a signal S n  proportional to N. The signals S n  S b  are fed to a common gate circuit 30, the signal S b  being used to switch the gate on and off, successive pulses effecting these operations alternately. The number of pulses S n  passing through the circuit when switched on is measured, i.e. the number of cycles of S n  for one cycle of S b  is determined, and hence the ratio N/#T is determined.

Abstract: 3 - Hydroxymethyl - ceph - 3 - em - 4 - oic acids of Formula (II) <FORM:1121308/C2/1> in which X represents an acylamino or amino (NH2) group, are prepared by the hydrolysis of compounds of Formula (I) <FORM:1121308/C2/2> in which X is as defined above, by means of wheat germ esterase or an esterase derived from a species of the genus Rhizobium. Specified species are R. trifolii, R. lupinii, R. japonicum, R. leguminosarum and R. phaesoli.  A wild-type strain of R. trifolii is preferred.  The microorganism is cultured in a medium containing (a) meat extract and peptone, or (b) yeast extract, mannitol and nutrient salts in submerged culture.  The cells are harvested, washed and poured into acetone.  The solids so obtained are used in the hydrolysis process. An aqueous extract of defatted wheat germ is also used.  The hydrolysis is effected at pH 5 to 8 in aqueous media and the pH is maintained within this range by the addition of NaOH. After completion of the hydrolysis, protein is precipitated by the addition of a watermiscible solvent, e.g. acetone and the 3-hydroxymethyl ceph - 3 - em - 4 - oic acid is extracted with a water-immiscible solvent or is adsorbed on an anion exchange resin, if not soluble in a solvent. In the case of 3-hydroxymethyl-7-amino-ceph-3-em-4-oic acid, adjustment to pH 4.5 is sufficient to cause the product to precipitate. A typical compound is 7-benzylthioacetamido-3 - hydroxymethyl - ceph - 3 - em - 4 - oic acid.

Filed: 1966-10-14
Abstract: 1,121,028. Counters. FERNSTEUERGERATE - ZACHARIA - OELSCH - MEIER. 14 Oct., 1966 [16 Aug., 1966], No. 46027/66. Heading G4D. [Also in Division G1] A D.C. integrating voltmeter or ammeter consists of a D.C. motor 12 and associated gearing by which it drives a roller counter 34 which is visible through a window 14 in the front face 11 of the meter casing. This front face is rectangular and is required not to exceed the DIN standard dimensions of 72 mm. high by 36 mm. wide. This is achieved by using a miniature motor, of not more than 30 mm. in diameter and 60 mm. in length. Such a motor has a higher speed than the larger motors conventionally used in such meters, and so a correspondingly greater gear reduction is necessary in the drive connection between the motor and the counter. The casing is therefore so dimensioned that two or more gear shafts &c. can be positioned between the motor and the counter. These shafts 21, 22, 23, 26 and the counter shaft 16 are horizontal shafts mounted between a pair of vertical plates (19), (20), (Fig. 2, not shown) which are disposed in the upper front portion of the meter casing. They are driven by a worm drive 24-25 connecting the vertical shaft 13 of the motor to the first horizontal shaft 26. The space beneath the gearing and in front of the motor is available for ancillary indicating apparatus, e.g. a photo-electric (Fig. 4, not shown) or Hall effect device responding eleotrically to rotations of a member driven by the gear train, or a potentiometer resistor (40), (Fig. 5, not shown) similarly driven.

Abstract: 1373782 Fibre-plastics laminates ENGLISH ELECTRIC CO Ltd 5 Oct 1972 [5 Oct 1971] 46349/71 Headings B5N and B5A Fibre-reinforced plastics material is made by impregnating at least one layer of a fibrous material (A) with synthetic resin, passing the material through a first die under such conditions of temperature and time that the impregnant thoroughly wets the material and is not fully set (but is preferably gelled), applying a layer of fibrous material (B) over at least part (preferably the whole) of the surface of material (A), impregnating material (B) with synthetic resin, and passing the laminated product through a second die under such conditions of temperature and time that all the impregnant is fully set. The fibrous material (A) may comprise a plurality of layers of woven or non- woven glass, sisal or polyester, which may either be fed together through a chamber into which the impregnant resin is introduced or be separately impregnated and pressed together before or during passage through the first die. The impregnated material (A) may have core layers of balsa wood, asbestos, steel wire or aluminium incorporated therebetween before passage through the first die. After passage through the first die the structure may be coated with resin, and, before application of material (B), may be degreased or shot-blasted. The fibrous material (B) may be continuous filament tow or woven continuous filament tow of carbon fibres, and may be formed as a series of strips. The impregnant resins for (A) and (B) may be the same or different and may be polyvinyl chloride, polyethylene, polytetrafluoroethylene, polyester or epoxy resin. The process may be carried out centinuously by passing the materials through two series of units each comprising an impregnation chamber into which resin is injected as the materials pass through and a die which is heated by platens such that it comprises a cool portion followed by a hot portion (see Fig. 2, not shown), the hot portion being longer in the second die to ensure full setting. Specified cool and hot temperatures are 15-70 C. and 115-135 C. for isophthalic polyester. The two dies may be of the same or different cross-sectional shape and the second die should allow a wider gap than the first. The fibrous materials (A) and (B) may be partially impregnated, before the process is carried out, by passage through a bath of resin.
