Title: Improvements in or relating to apparatus for use in connection with machines for sewing on buttons
IPC: D05B3/22
Filed: 1946-10-08
Abstract: 617,583. Sewing-machines ; setting buttons. BELLOW, A., and CARTER, A. F. Oct. 8, 1946, No. 29958. [Classes 43 and 112] A button-attaching machine is provided with apparatus for feeding buttons from a hopper, comprising a chute along which the buttons pass to a carrier at the end of a swinging arm which transfers them one at a time to the stitching point. In the form shown flat buttons 3 pass singly from a hopper 1 down a chute 2 to be picked up one at a time by a spiked wheel 4 driven at a suitable speed, preferably intermittently. The wheel 4 carries each button round inside a resilient guard 6, which retains it on the wheel, until it reaches the lowest position, when a rod 7, actuated in synchronism with the wheel, pushes the guard back to allow the button now face upwards, to fall on to a spiked carrier on the end of a swing- ing arm 8 which carries it to the stitching point ; the button is correctly positioned to engage the spikes of the carrier by the force of gravity while it is being carried by a single spike on the wheel 4.

Title: Process for the manufacture of 7-dehydro-cholesterol and its esters
IPC: C07J75/00
Filed: 1945-11-09
Abstract: 7-Dehydrocholesterol and its esters are manufactured by treating a 7-bromocholesterol ester, or a reaction mixture containing it, with an alkaline-earth metal oxide or hydroxide, preferably in the presence of an inert diluent with a high dielectric constant, and, if desired, hydrolysing the product. The 7-bromocholesterol ester is advantageously made by brominating a cholesterol-3-ester by treatment with an N-brominated acid imide in an inert solvent in the presence of a small proportion of an unsaturated organic compound as activating agent and preferably also in the presence of an alkaline-earth metal oxide, hydroxide or carbonate as acid-binding agent.  The product is preferably dehydrobrominated without isolation, though it can be isolated in a crystalline state by removing the solvent in the presence of pyridine as a stabilizing agent.  In examples: (1) cholesterol acetate is treated with N-bromosuccinimide in petroleum ether in the presence of cyclohexene and calcium hydroxide, part of the solvent is distilled off under reduced pressure, the residue is diluted with xylene and nitrobenzene and heated with calcium hydroxide, the solvents are removed by steam distillation after adding sodium carbonate, and 7-dehydrocholesterol acetate is isolated from the residue or is hydrolysed to 7-dehydrocholesterol by means of alcoholic potassium hydroxide in ether or benzene; (2) the calcium hydroxide is omitted from the first step of (1) and replaced by barium hydroxide in the second step; (3) cholesterol propionate is treated with N-bromophthalimide in petroleum ether in the presence of cyclohexene and barium oxide, and the product is treated as in (1); (4) cholesterol acetate is refluxed with N-bromosuccinimide in petroleum ether in the presence of calcium oxide, the solution is separated and evaporated after adding a trace of pyridine, and the 7-bromocholesterol acetate obtained is recrystallized several times from acetone and dehydrobrominated by the process of (1).

Title: Method and apparatus for the fermentation of solid organic waste materials
IPC: C05F17/02
Filed: 1953-11-03
Abstract: 756,373. Treating sewage and refuse; fertilizers. DANO INGENIORFORRETNING OG MASKINFABRIK, INGENIOR KAI PETERSEN'S FOND. Nov. 3, 1953 [Dec. 11, 1952; March 5, 1953], No. 30408/53. Class 111. Material to be composted is introduced at 9, Fig. 9, and moved by a worm 14 into the heating zone I of a drum 10, the heat being derived from the gases resulting from fermentation taking place in a zone II, which gases are passed through the heating zone and discharged through apertures in the region D of the drum. Compressed air is supplied through a pipe (not shown) to a fixed distributer member 32, Fig. 3, surrounding the entrance neck, and passes through a slit 34 in it to apertures 20 in those ducts 22 which at the time are in communication with the slit. The material reaches the fermentation zone II at an optimal temperature of 35-50‹ C. If its moisture content is insufficient, water may be introduced at 24 from a pipe 26 controlled by a slit 36 in the distributer 32. If the fermentation is so vigorous that the above temperature range is exceeded, more air may be supplied; undue desiccation of the material may be counteracted by admission of water. The material may be subjected to pasteurization by permitting its temperature to rise to 60-70‹ C., preferably at the end of the fermentation zone where it passes to the drying zone III. In the drying zone more air is supplied which also effects cooling of the material. Alternatively to, or in addition to, the apertured pipes 22, air may be supplied by an axial, apertured pipe 40, Fig. 9. The drum may be divided axially, in at least the fermentation zone, by partitions 44, Fig. 11, which provide air or liquid ducts 46, 48 where they meet one another and the drum wall. The heating zone may be made of larger diameter than the remainder of the drum (Fig. 10, not shown).

Abstract: 859,372. Automatic gramophones. HANSEN, H. C. Oct. 16, 1957 [Oct. 9, 1956], No. 30756/56. Class 40 (2). In a record changer having a control mechanism with a plurality of cam tracks and a track follower associated with the tone arm arranged to climb or descend sloping wall portions of one or more tracks as in Specifications 852,061 and 859,371, the track follower is arranged on an arm which is tiltable against resilient action. In the embodiment described, a follower arm 194 is provided by diametrically spaced balls whereby the said arm 194 may tilt a small amount limited by flaps 272a, 272b laterally disposed with regard to the balls. The follower arm 194 is frictionally mounted on the tone arm spindle 260 and controls the horizontal movements of the tone arm 150 as described in the above-mentioned Specifications. Similarly, the vertical movements are effected by a lever 250 acting on the underside of the cam-disc. The automatic cycle is initiated in well-known manner by a tap-tap lever 228 which rests on, and is frictionally coupled to, a hook-shaped lever 225 having an aperture engaged by a pin on an arm 227 on the tone arm spindle. The manner in which the setting down of the pickup is controlled by the engagement of the pickup with the edge of the next record to be played, in conjunction with the follower arm and the cam-disc ramp, and the manner in which the machine is switched off after the last record is substantially as in the prior mentioned Specifications. The machine may be started and stopped by a subsidiary control 113a for manual control of the pick-up for the playing of single records. In such case the drive of the turntable is stopped and started by a bar 172 which operates the switch bar 136, but owing to lost motion between the latter and the main control lever 124 operated by control 113, movement of the cam disc 190 is not initiated. At the end of a record, however, the tap-tap lever initiates an automatic cycle to lift and return the pick-up and stop the machine in the usual manner. Specification 757,379 also is referred to.
