Title: Process for the production of spray-dried food extracts, in particular coffee extracts
IPC: A23F5/20
Filed: 1961-03-23
Abstract: In the process for the production of a dried food product according to the parent Specification, which comprises charging a food in liquid form with an inert gas under superatmospheric pressure, aromatic constituents of the food having previously been entrained in the inert gas, and thereafter spray-drying the mixture to yield a free-flowing powder, the liquid form of the food is a concentrate prepared from the food after extracting aromatic substances and subsequently carrying out a steam or other treatment deleterious to the aromatic content of unextracted food and the aromatic substances extracted are included with the gas-charged concentrate before the spray drying.  The extraction may be carried out by vacuum distillation, steam distillation, solvent extraction, or blowing-out with an inert gas at an elevated temperature.  According to an example, from 100 Kg. of roasted coffee beans the aromatic substances were distilled off under vacuum and condensed at about -80 DEG C, after which the steam volatilisable aromatic substances were separated and combined with the vacuum condensate in the form of an emulsion.  The residue of the coffee beans from the de-aromatization was then subjected under pressure to steaming for improving the taste and digestibility by removal of caffeine, and was subsequently ground and extracted with water, in part at an elevated temperature of above 100 DEG C.  The aqueous concentrate so obtained was then charged with inert gas containing the aromatic substances and thereafter the mixture was spray-dried to powder.

Title: Improvements in tyre building drums
Inventor: SMITH SALATHIEL SAUNDERS
IPC: B29D30/24
Filed: 1952-05-06
Abstract: 736,007. Tyre building drums. INDIA TYRE & RUBBER CO., Ltd. April 24, 1953 [May 6, 1952], No. 11372/52. Class 144 (1). In a collapsible tyre building drum comprising a hub 5 and a pair of diametrically opposite radially movable arcuate segments 1, each segment comprises two axially movable part segments la and the remainder of the drum periphery is formed by a plurality of radially movable arcuate segments 18 located between the segments 1 and adapted to collapse over and around them when the constituent part segments la are in their radially and axially innermost position, means being provided for effecting radial movement of the segments 1, 18 and axial movement of the part segments 1a. As shown co-operating part segments 1a are engaged respectively by the oppositely screwthreaded ends of a shaft 2 rotatably journalled at its centre in a head 6a of a radially extending rack 6, rotation of the shaft 2 thereby effecting relative axial movement of the part segments la. Each part segment la carries a drum edge part 4 which is slidable on the inner periphery of an arcuate plate 3 attached to the rack head 6a. To ensure axial alignment of the part segments la of each pair on adjustment, each part carries axially extending guide bars 12 or 13 which slidably interengage and are slidably located in housings 15 fixed to the rack head 6a. Radial adjustment of the segments 1 and 18 is effected by pinions 29 and 30, Fig. 5, rotatably mounted coaxially within the hub 5 to engage respectively the two racks 6 and two racks 17 extending radially inwardly from the intermediate segments 18. The pinions 29 and 30 are driven by a rotatable sleeve 36 which is slidably mounted within the pinions and carries a dog clutch 38, 37 at each end to engage respectively, on appropriate axial movement, with dog clutches 32 and 35 carried by the pinions 29, 30, the sleeve being urged by a spring 40 normally to engage the clutches 37 and 35. The intermediate segments 18 each comprise arcuate drum edge parts 20 which are slidably bridged by arcuate periphery plates 19 to allow for axial width adjustment of the drum, and hinged on each side of each segment 18, at the radially inner corners of the drum edge parts 20, is an additional axially adjustable segment 24. The segments 1, 18 and 24 provide a substantially continuous drum periphery in the expanded position. Each segment 24 is connected to its segment 18 by a compression spring 28 so that when the segments 1 are moved, by operation of the shafts 2 and pinion 29, to their collapsed position, Fig. 3, the segments 24 are urged thereover by their springs 28. Subsequent radially inward movement of the segments 18 by operation of the pinion 30 causes the segments 18 and 24 to close further around the segments 1.

Abstract: 542,246. Supporting lamps. SHEPHERD, G. R. (Westinghouse Electric International Co.). July 8, 1940, No. 11395. [Classes 75 (iii) and 75 (iv)] [Also in Group VI] Lighting apparatus, particularly for use in hospital operating rooms, has means for generating ultra-violet radiations arranged in conjunction with the lumination lamp; regulating means are provided so that the intensity of the ultraviolet radiations are maintained at a constant value on the patient on the operating table whatever be the position of the lamp. The lamp unit is shown in Fig. 1 suspended, above the operating table 4, from the ceiling support 6 in which it is rotatable. The hanging member 5 supports a bifurcated member 7 in which is pivoted a shaft 9 carrying the lamp unit in a bifurcation at one end and a counter-weight 12 at the other. The lamp unit consists of a spider 16 and a framework 14 of a truncated conical form carrying a number of inclined trapezoidal mirrors 15; the lamp is arranged at the centre at the focus of an annular Fresnel lens. A control knob 17 protrudes from the counter-weight 12 and by means of suitable mechanism enables the shaft 9 and the lamp unit to be swung into various positions about their supports, while the lower periphery of the lamp unit is maintained parallel to the table. The unit is provided with two semi-circular ultra violet lamps 18 arranged at the periphery in a reflecting section formed by the curved lower part 19 of the frame 14, and a parabolic section 20. The ultra-violet lamps 18 are connected to the supply through a transformer 24 and rheostats 25, 36. The latter 36 can be set so that a pre-selected maximum violet ray intensity cannot be exceeded. The former 25 is automatically varied as the position of the lamp unit is varied. A housing 22 is carried by the member 7 and encloses the transformer 24. A shaft 27 with a control knob 28 protrudes from the housing and carries a pinion 29 meshing with a rack bar 30 pivoted to a link bar 33 secured to the yoke 21 by a nut and bolt arrangement 34 which can be adjusted in the slot 35. By means of this adjustment the rheostat 36 is set and the nut 34 tightened to maintain its position. The set-screw 37 is loosened and control knob 28 is manipulated to set the rheostat 25 to an appropriate value corresponding to the position of the lamp and the set screw is then tightened. Thereafter the rheostat 25 is adjusted automatically when the lamp unit is moved. In a modification the adjustment is effected  hydraulically.
