Title: Improved Depositing Apparatus
Inventor: BAKER DONALD ERNEST
IPC: A23G3/02
Filed: 1966-03-16
Abstract: 1,186,854. Depositing batter, jam, or cream. E. T. OAKES CORP. 16 June, 1967 [16 March, 1966], No. 11619/66. Heading A2A. Apparatus for depositing a paste-like or highly viscous substance such as batter, jam or cream in amounts each having a pre-determined shape and size on the upper surface of an endless travelling conveyer belt 13, or on bakery products such as cakes or biscuits placed thereon, comprises a hollow, cylindrical stationary member 23 having a longitudinal peripheral slot 27, which member 23 is concentrically located within a hollow, rotatable, cylindrical member 24 having a peripheral aperture 28, corresponding in shape to said predetermined shape and coming into register with the slot 27 during each rotation of the member 24. The two ends of the cylindrical member 23 are closed, and the substance is fed centrally into the member 23 through a pipe 29. The member 24 is journalled in brackets 15 depending from a frame 11, in which a wheel 12 supporting and driving the conveyer belt 13 is also journalled. An electric motor 16 rotates the wheel 12 through a belt 18 and pulley 20, and also rotates the member 24 through a pulley 19, belt 17, pulley 21 and a reversing gear box 26, so that the peripheral speeds of the member 24 and belt 13 are equal. The width of the slot 27 may be adjusted to vary the amount of the substance which is dispensed from the aperture 28 each time the slot and aperture come, into register. The member 24 may have a plurality of peripheral apertures 28 circumferentially and/or axially spaced apart. The rotatable member 24 may be located inside the stationary member 23, which enables the slot 27 to be made adjustable.

Title: Improvements in or relating to means for regulating internal combustion engines having variable compression spaces
IPC: F02B75/04
Filed: 1935-04-15
Abstract: 458,258. Fluid-pressure servomotor-control systems. ANDREAU, J. E., 73, Boulevard Montparnasse, Paris. April 15, 1935, No. 11626. Convention date, April 14, 1934. [Class 135] [See also Group XXVII] In an internal-combustion engine in which the compression space is varied by a servomotor, the intake throttle valve is opened by the means for varying the compression space, but is closed directly by the servomotor controller. The variation of the compression space may be effected by adjusting the crank-shaft axis, or the length of the connecting-rods, but the means described are adjustable cylinder heads. In a multicylinder engine, cylinder heads are adjusted simultaneously by being surrounded by threaded rings which are rotated by arms 6, connected through springs 15, 16 to a rod 14. This rod is reciprocated by a servomotor comprising a piston 18 and a valve 19 controlling the flow of pressure fluid from an accumulator 20 served by a pump 21. The springs 15, 16 enable the variation of pressure during the engine cycle to assist in the movement of the cylinder heads. Depression of a pedal 24 moves the valve 19, through links 36, 31, pivoted at 37, 30, and admits pressure fluid to move the rod 14, which carries, rigidly attached thereto, a member 27, 29 ; this member allows a spring 35 to open the engine throttle valve 23 and moves the pivot 30 so that the valve 19 is closed. When the pedal 24 is released, engagement with the end of a slot 34 causes the lever 28 to close the valve 23. The pivot 37 is mounted on a diaphragm 26 subject to the induction pipe suction, but it may also be connected to a diaphragm subject to atmospheric pressure. A hydraulic clutch 38 is provided. The Specification as open to inspection under Sect. 91 comprises also other means for adjusting the cylinder heads, viz. laterally displaceable wedges, and cams rotatable on traverse shafts ; curves are given showing torque variation within a speed range regulated by a speed governor. This subject-matter does not appear in the Specification as accepted.

The chromiferous dyestuffs may be made by treating the azo compound under weakly acid, neutral or alkaline conditions with the appropriate quantity of chromiumyielding agents.  Preferably 0.5-0.6 atomic proportions of chromium-yielding agent are used per molecular proportion of azo compound.  The azo compounds may be made by coupling a diazotized 2-amino-phenol carrying an SO2R group in the 4 position with an appropriate 1-carboalkoxyamino-7-naphthol. Specified diazo components are 2-amino - phenol-4-ethyl-,-isopropyl-,-propyl- and n-butyl-sulphone.  Specified coupling components are 1-carbo-methoxy-ethoxy-, -n-butyloxy-and-isopropyloxy-amino-7-naphthol.  Specified chromium-yielding agents are chromium sesquioxide, fluoride, chloride, formate and acetate, mixtures of chromium salts with alkali metal or ammonium salts of aliphatic hydroxy carboxylic acids, e.g., tartaric acid and ammonium - oxalato - aminochromate.  The chroming reaction may be effected at elevated temperatures in aqueous media preferably in the presence of an organic solvent such as ethanol, n-butanol, ethylene glycol, b  - ethoxyethanol, cyclohexanol, dimethylformamide, mono- and di-ethanolamine and pyridine. Chroming may also be effected with an alkali metal chromite and glycerol in an alkaline aqueous medium.  Wetting or dispersing agents may be present.  The dyestuffs dye wool and silk and synthetic proteins from neutral or weakly acid dyebaths.  They dye wool in grey tints.  They may be used for colouring lacquers, varnishes and plastic materials. Examples are provided of the preparation of dyestuffs using certain of the above specified components.  Specification 667,168 is referred to.
