Title: Improvements in and relating to hoists
IPC: B66D3/22
Filed: 1935-07-19
Abstract: 446,871. Winches. BURGESS, A. F., 10, New Court, Lincoln's Inn, London.- (Harnischfeger Corporation ; 4400, West National Avenue, Milwaukee, Wisconsin, U.S.A.) July 19, 1935, No. 20604. [Class 78 (v)] In a hoist having motor driven gearing for driving the drum in either direction, the imparting of a lowering movement causing the automatic actuation of a restraining brake, the gearing comprises two internally toothed gear members 38, 40, Fig. 1, meshing with rigidly connected planet pinions 33, 34, the gear 40 being secured to the drum 4 while the gear 38, during the lowering movement, is permitted a limited rotation to actuate the automatic brake. An electric motor 5 drives a shaft 26 on which is fixed a driving pinion 30 meshing with the pinions 33 of the planet pinions which rotate on shafts 35 mounted in plates 36, 37 of a carrier. The automatic brake comprises a braking disc 47 connected to the carrier plate 37 by a one-way clutch 49, 50 and disposed between braking discs 45, 46 of which the disc 45 is fixed and the disc 46 is capable of a limited rotary and sliding movement. Arms 60 extend from the gear 38 through arcuate slots in the disc 46. When the drum 4 is being rotated in the lowering direction, the gear 38 rotates and the arms 60 rotate the disc 46 in such a direction that cams thereon engage cams on a fixed plate 57. This causes the disc 46 to move towards the disc 45 and press against the braking disc 47. When a load is being raised, the disc 47 is disconnected from the carrier plates 36, 37 by the clutch 49, 50. A stopping brake 10 comprises a disc 70 mounted on the hub 31 of the driving pinion 30 and disposed between fixed and movable discs 65, 66. The disc 66 is urged towards braking position by a lever 71 under the action of a spring-pressed plunger 74 which is withdrawn, when the motor 5 is running, by the pivoted armature 80 of an electromagnet 81 in the motor circuit. The switch controlling the motor 5 comprises an arm 89, Figs. 2 and 8, having contacts 90, 91 movable over contacts 87 on segments 85, 86, the arm being moved to the right or left according as the motor is to run in the direction for hoisting or lowering. The arm 89 is pivoted on a shaft 93, but is releasably connected thereto by a link 99 having a stud 102 engaging a notch 101 in an arm 98 fixed to the shaft 93, the stud being held in the notch by a spring 103. Fixed to the shaft 93 is an operating lever 19 provided with pull cords 191 for turning the shaft 93 and the switch arm 89 in either direction. If, during hoisting, the load block 11 approaches too close to the drum 4, it moves a lever 20, Fig. 2, which depresses a rod 109 and a crank arm 112 pivotally mounted on the shaft 93. A camming arm 113 on the arm 112 releases the stud 102 from the notch 101 so that the switch arm is turned on the shaft 93 by a spring 94 to circuit breaking position as shown in Fig. 8, thereby stopping the motor 5. Should the block continue to approach the drum, the lever 20 will cause the camming arm 113 to move the switch arm 89 and reverse the motor.

Title: Improvements in or relating to supply circuits
IPC: G05F1/56
Filed: 1954-07-16
Abstract: 751,679. Automatic voltage-control systems. PHILIPS ELECTRICAL INDUSTRIES, Ltd. July 16, 1954 [July 18, 1953], No. 20866/54. Class 38 (4). The D.C. voltage applied to a load is stabilized by connecting a D.C. source to the load via the emitter/collector path of a junction transistor or via the collector/base path of a pointcontact transistor, and controlling the first transistor by a second transistor in accordance with the difference between load voltage and a reference voltage. In one embodiment, Fig. 1, the load 2 is supplied from a battery 1 via junction transistor 5 which has its base connected via resistor 7 to the collector of the second junction transistor 6. A reference source 3, having one pole common with the battery 1, is connected to the base of transistor 6, the collector of which is connected via resistor 7 to the base of transistor 5. Variations in load voltage are amplified by transistor 6 to control the base current of transistor 5 and hence the supply to the load. Resistor 8 serves to maintain the correct bias voltage for the base of transistor 5 and the collector of transistor 6. The reference source 3 may be shunted by a resistor 9 to carry the reverse current which would otherwise flow through the source 3. In a modification, Fig. 2 (not shown), the transistor 6 is replaced by one of opposite conductivity type, so that the resistors 7 and 8 of Fig. 1 may be dispensed with. In a second modification, Fig. 3, the load 2 is supplied from battery 1 via the collector/emitter path of transistor 5<SP>1</SP>, the base of which is again connected to the collector of transistor 6 which now has its base connected to the load and its emitter connected to the reference source. Resistors 7, 8 again provide bias. In a third modification, Fig. 4 (not shown) the transistor 6 of Fig. 3 is replaced by one of opposite conductivity. In a fourth modification, Fig. 5, the load 2 is supplied via the collector/base path of a point contact transistor 5<SP>11</SP>, the emitter of which is controlled by the junction transistor 6.

A curved windshield 15 comprises two sheets of glass 17 and 18 bonded together with between them a thermoplastics interlayer 19, e.g. of polyvinyl butyral, which has graded bands 20 and 21 of glare-reducing dye across the length of the windshield adjacent its upper and lower edges and is curved in such a way that when the windshield is mounted in functional position the inwardly opposed edges 22 and 23 of the glare-reducing bands are horizontal. Apparatus for preforming the interlayer comprises a rectangular frame 25 having pairs of slots 29 in its upper and lower rails 26 and 27 whereby clamping bars 32 can be bolted to the frame at an adjustable distance apart. U-shaped brackets 47 extend downwardly from a plate 46 welded to the upper rail 26 and rods 50, threaded at one end to receive wing nuts 51 and affixed to a clamping member 53 at the other end, extend through apertures in the brackets. Method.-A rectangular plastics sheet having glare-reducing bands adjacent its longitudinal edges is clamped between the clamping bars 32 which are then bolted to the frame 25 located in a heating chamber. The sheet is clamped along its upper edge by the member 53, the wing nuts positioned on the rods 50 to a predetermined distance from the bracket ends, and weights 61, 62 and 63 are suspended from spring clamps 64 fixed along the lower edge of the sheet. The temperature in the chamber is raised to between 150-250 C. so that the plastics sheet is deflected downwards until it is partially arrested when the wing nuts 51 rest on the bracket ends. Deflection of the lower edge is allowed to continue until the sheet has the required curvature when it is then cooled, removed from the frame and the final interlayer cut therefrom. More than one sheet may be preformed simultaneously.

Patent GB-585760-A (GB)
Title: Improvements in or relating to photographic emulsions
IPC: G03C1/04
Filed: 1944-10-30
Abstract: 585,760. Photographic emulsions. HART, J. A. H., and LEE, E. W. Oct. 30, 1944, No. 21093. [Class 98 (ii)] A photographic emulsion comprises a dispersion of silver halide in a colloid medium which includes both a hydrophobic colloid (e.g. cellulose nitrate or acetate or ether, polystyrene, polymethyl methacrylate, or polyvinyl acetate) and a colloid containing free acid groups (e.g. a partially hydrolysed polymethyl methacrylate, cellulose acetic acid, alkyd resins containing free acid groups such as the condensation products of glycerol, glycols, or sugars with polycarboxylic acids such as phthalic, succinic, tartaric, or maleic acid, interpolymers of maleic anhydride with styrene, methyl methacrylate, or rosin, polyvinyl esters of polybasic acids such as polyvinyl phthalate, or a natural resin such as silvestic acid, the alkali-soluble fraction of Yellow Gum Accroides, abietic acid, or shellac). The colloid medium may contain a water-soluble colloid such as gelatin, or a silver halide dispersing agent, but should be readily dispersible in a predominantly organic solvent medium. If the acid colloid is freely soluble in dilute alkali, the proportion of such colloid is less, up to 90 per cent. The silver halide may be formed by double decomposition in the colloid medium or in one of the colloid constituents, the other colloid or colloids being later added. The silver halide may be formed in the acid colloid dissolved in an aqueous or aqueous-organic solvent medium, but is preferably first formed in gelatin, ripened and digested therein, separated by sedimentation or otherwise, and redispersed in the colloid medium. In an example, salicylic acid is added to a ripened and digested gelatino silver bromide emulsion, which is then melted and diluted with methyl alcohol. After standing, the supernatant liquid is decanted, the sedimented silver bromide stirred with methyl alcohol, allowed to stand and most of the supernatant liquid decanted, and added to a composition comprising methyl alcohol solutions of cellulose nitrate and partially hydrolysed polymethyl methacrylate, ethyleneglycol monomethyl ether, and methyl alcohol. The resultant emulsion is spray-coated on to a cellulose nitrate surface on a metal sheet. Other solvents such as acetone, ethyl alcohol, ether, or dioxane may be used, or the colloids may be separately dissolved in different solvents and the solutions mixed. The emulsion may also be applied to a support by dipping or beading, and the support may be of cellulose nitrate or acetate film, glass, or paper. The emulsion may contain sensitising -dyes, stabilizers, dyes, or dye intermediates such as colour formers. Specifications 397,489 and 573,917 are referred to.
