A cooling air blower 2 for a vehicle engine cylinder 1 is driven by an hydraulic coupling having a throttled outlet 4 and an inlet 3 so controlled by a thermostat 5 that on reduction of cylinder temperature the inlet pressure is reduced both to increase the coupling slip and to allow a spring 8 to force back a piston 9 acting, e.g. by reducing cooling or effecting heating of a supercharger delivery, to effectively pre-heat the engine combustion air. The invention is applicable to multi-fuel engines.

Title: Dc motor speed control circuit
IPC: H02P7/292
Filed: 1974-02-27
Abstract: 1454871 Automatic control of speed GENERAL ELECTRIC CO 27 Feb 1974 [6 March 1973] 8939/74 Heading G3R A D.C. motor, fed from an A.C. source through a full wave rectifier bridge with controllable rectifiers in each leg, has its speed regulated according to the error between a reference value and a speed dependent voltage across the motor armature, the error being switched to a firing angle control device for the rectifiers when the sensed armature current is zero. The firing angle of the rectifiers is thus determined by the motor speed error at zero armature current i.e. when the IR drop of the armature is zero. The voltage across the armature is then a true representation of the motor speed and errors due to the armature IR drop are eliminated. As shown, the full wave rectifier bridge comprises thyristors 42, 44, 46 and 48 and the field 16 of motor 28 is energized from a second bridge 12. At zero armature current, as sensed by resistor 50 or a magnetic amplifier, switch 66 is enabled to allow a motor speed error signal to thyristor control 32. The speed error is formed by comparator 58 from the actual speed i.e. the armature voltage of D.C. shunt motor 28, as measured using divider 52, 54, and from a reference valve from potentiometer 61.

Title: Manufacture of ester-like derivatives of ortho:ortho-dioxy-monoazo-dyestuffs
IPC: C09B43/18
Filed: 1948-04-02
Abstract: Ester-like derivatives of o : o1-dihydroxymonoazo dyestuffs containing a single sulphonic acid group are manufactured by treating the dyestuffs, in an aqueous alkaline medium, with organic acylating agents which contain as the sole acylating group a functionally converted carboxyl group and which are otherwise free from groups imparting solubility and substituents convertible into such groups by hydrolysis.  As starting materials may be employed any monosulphonated monoazo dyestuffs containing the grouping <FORM:0648715/IV (c)/1> and especially those containing at least once the residue of a component of the benzene or naphthalene series, obtainable by coupling the diazo compound of an o-aminophenol or o-aminonaphthol, which may contain further substituents (e.g. halogen atoms or nitro, alkyl, alkoxy or sulphonic acid amide groups) with a component coupling in vicinal position to a phenolic or enolic hydroxy group, e.g. hydroxybenzenes, 8-hydroxyquinolines or especially hydroxynaphthalenes coupling in o-position to the hydroxy group, acetoacetic arylides, 2 : 4-dihydroxyquinoline, or pyrazolones, especially 1-aryl-3-methyl-5-pyrazolones.  Specified components are those enumerated in Specification 636,681 and additionally in that Specification as open to inspection under Sect. 91.  Suitable acylating agents are those referred to in the said Specification, and the products may be used for the purposes therein described. In dyeing by the single bath chroming process it s sometimes advantageous to add a wetting or dispersing agent, which may be ionogenic or preferably non-ionogenic, e.g. a polyglycol ether of a fatty alcohol of high molecular weight.  Examples describe esterifications in aqueous solutions of sodium acetate and caustic soda, or caustic soda alone, or sodium carbonate, and the dyeing of wool with certain of the products.  Specification 380,431 also is referred to.  The Specification as open to inspection under Sect. 91 comprises also the treatment of other o : o1-dihydroxymonoazo dyestuffs, and the use of other acylating agents, maleic and terephthalic anhydrides being additionally specified.  This subject-matter does not appear in the Specification as accepted.

Title: Improvements in sterilizing containers
IPC: A61L2/26
Filed: 1943-06-11
Abstract: 569,395. Sterilizing containers. INGENIORSFIRMA VIGGO AKTIEBOLAG. June 11, 1943, No. 9411. Convention date, June 20, 1942. [Class 81 (i)] A sterilizing container consists of an inner basket 5 made of perforated material or netting which is inserted in a bag 8 made of filter paper or textile material, and both of which are inserted in a perforated outer casing 1 having a lid 2, a germ-tight seal being provided between the bag and the outer casing. The seal may be formed as shown in Fig. 6 by projecting ribs 9 and 10 on unperforated upper edge flanges of the casing and basket with the bag passing in zig-zag fashion between them. A seal may also be formed between the lid and the edge of the casing and/or basket, for example, as shown in Fig. 6, by using a bag extending above the top of the basket and folding it over the edge of either the casing or the basket, or as in Fig. 7, by providing two circumferential sealing strips 14 to fold over both parts. One of these sealing strips may be constituted by the extended upper edge of the bag and the strips may be of greater tensile strength than the rest of the bag. To assist in forming the seal, a rib 15, projecting downwards between the basket and the casing, may be provided on the lid. The sealing material folded over the edge of the casing may project under the lid so as to be visible from the outside. The lid may be formed of two walls of perforated material enclosing a germ filter. The Specification as open to inspection under Sect. 91 describes a construction of the twowalled lid with reference to a drawing in which the two walls are fixed together by clamps hinged on to a rim round the lower wall. This subject-matter does not appear in the Specification as accepted.
Patent GB-600027-A (GB)
Title: Improvements in cathode-ray tube spectrographs
IPC: G01J3/32
Filed: 1945-04-16
Abstract: 600,027. Photometric apparatus. DUMONT LABORATORIES, Inc., A. B. April 16, 1945, No. 9450. Convention date, April 15, 1944. [Class 40 (iii)] The invention relates to a spectrograph or colour analyser wherein a photo-tube is used to scan a spectrum produced from the light to be analysed, and its output after amplification is applied to the Y plates of a cathode-ray tube, to the X plates of which is applied a voltage to synchronize the X deflection with the scanning of the spectrum so that the tube indicates intensity against spectral component. According to the invention, scanning of the spectrum is effected by an electrically vibrated reflector and a slotted plate, the electrical vibrator and the X plates of the cathode-ray tube being fed from the same source. As shown, light to be analysed, from a source 3 or reflected from an object under investigation, is projected through a lens system 4, 7 and diffraction grating 8, or other dispersing means, to produce a spectrum which is reflected by a mirror 9 through a slot 10 on to a photo-electric cathode 19. The mirror 9 is mounted on a spring 12 vibrated by a magnet 15 fed from A.C. mains 2 to scan the spectrum. The photo-tube output is amplified at 28 and applied to the Y plates 31 of a cathoderay tube C, the X plates 37 of which are energized from the mains 2 through a transformer 39, phase-shifter and amplifier 48 so that the X deflection is synchronized with the scanning mirror 9. The cathode-ray tube thus indicates the intensity of the various spectral components against wavelength. Centring of the indication on the cathode-ray tube screen is effected by the manually adjustable phaseshifting network 49, 42, 43, 44, and blackout during return of the spot may be effected by biassing the grid 34 with A.C. from tapping 46. The indication may be restricted to desired parts of the spectrum by adjusting the impedance 16 shunting the magnet 15 to alter the vibrational amplitude of the mirror 9, by adjusting the mean position of the scanning slit 10 or by increasing the gain of amplifier 48 feeding the X plates of the cathode-ray tube. A non-linear sweep for the cathode-ray tube spot may be used to compensate for non- linearity in the wavelength distribution of either the optical system of scanner. A mirror 50 may be used to project a colour spectrum from the grating 8 on to the cathode-ray tube screen to serve as a wavelength scale. According to the Specification as open to inspection under Sect. 91, scanning of the spectrum may be effected, alternatively, by longitudinal vibration of the slotted plate 5 or 11. This subject-matter does not appear in the Specification as accepted.
