Title: Improvements in apparatus for wrapping up quantities of pills, seeds, or any granular or pulverulent material
IPC: B65B51/00
Filed: 1940-10-10
Abstract: 541,195. Packeting. BEECHAMS PILLS, Ltd., and SUMNER, W. Oct. 10, 1940, No. 15091. [Class 94 (i)] Relates to apparatus described in Specification 252,090, [Class 94, (i)], for wrapping-up small quantities. of pills, seeds, or granular or pulverulent material, in which pills are deposited in a paper blank, and the edges of the blank are gathered into a neck by two grippers, one of which is rotated to twist the neck. According to the present invention, the lower gripper is moved downwards during the twisting operation in order to lengthen and consolidate the twisted portion of the neck. The pills are inserted in a paper blank 11 by a filling-tube 8 which descends and forces the blank through an aperture 26, and through the upper grippers 12 and the lower grippers 10, o form a receptacle. The plunger then rises and both sets of grippers close and form a neck on the receptacle which rests in the vertical discharge tube 38. The lower grippers 10 are pivoted to a circular member 37 which is rotated in one direction on the tube 38 by a spring pawl 54 attached to another circular member 52 that is oscillated on the tube 38. A spring 5, between the members 37, 52, presses the member 37 and the grippers 10 upwards, but a helical cam 6, secured to the member 37, engages a pivoted arm (not shown) and forces the member and the grippers downwards during the twisting operation. This draws the paper through the upper grippers 12, and forms a longer and consolidated twist. When the twist is completed and the grippers opened, the package falls through the tube 38, the arm is swung out of engagement with the cam 6 and the member 37 and the grippers 10 are raised by the spring 5. The foot of the tube 8 may be used to apply adhesive or wax to the paper to render the twisted neck airtight.

Abstract: 871,442. Refrigerators. TAMM, W. May 4, 1959 [May 3, 1958], No. 15269/59. Class 29 The relative humidity of the air in a refrigerating chamber is maintained constant, within limits, by supplying heat from an automatically controlled radiator i when the humidity is too high and water from a spray or trickle device c controlled by an automatic shut-off device l when the humidity is too low, the arrangement being such that water trickles or sprays over the radiator i and is evaporated on the surface thereof. A humidity responsive device h has two contacts 3, 9, the heater i being switched on when the contact 3 is engaged due to excessive humidity, and both heater i and the electromagnetically controlled water valve l when the contact 9 is engaged due to the humidity being too low. Neither the valve l nor heater i are switched on if the humidity lies between the desired limits. When contact 3 or 9 is engaged, a time switch k is set in motion so that the elements i, l are only on for a proportion of the time e.g. two minutes out of every ten. A fan may be used to force air in the chamber over the radiator which may be heated by hot water controlled by an automatically actuated valve.

Abstract: 387,214. Variable-speed gearing. TSCHERNE, A., 22, Kronenstrasse, Rorschach, Switzerland. June 7, 1932, No. 16051. Convention date, June 11, 1931. [Class 80 (ii).] Variable-speed gearing suitable for vehicles comprises an epicyclic train controlled by variable friction gearing with two sets of interpenetrating discs. A drum 3, Fig. 4, carries planets 9 meshing with a side gear 8 fast on a driving-shaft 1 and with a side gear 11 fast on a driven shaft 10. Fast to the drum 3 is a gear 13 meshing with two gears 14, Fig. 1, supported in a fixed frame 18 and connected by universally jointed shafts 15 to two shafts 16 mounted for parallel sliding motion on two pairs of slides 17, 171. These slides are supported in guides in the frame 18 and are formed underneath as racks, and the slides 17, 17<1> of each pair are constrained to move together by being connected by pinions 19, Fig. 2, on a connecting spindle. Coned discs 20, a set for each shaft, are freely slidable on feathers on the two shafts 16 and penetrate between discs 6 feathered on the shaft 1 and all slidable except the end one on the right of Fig. 1. Control of the speed is effected by moving a longitudinal slider 22 through gearing 35, Fig. 2, from a control lever 34. The slider 22 is formed with a rack 23, Fig. 1, on each side connected by a bell-crank lever 27 pivoted on the frame 18 and a link 28 to a slide 17. Thus displacement of the slider 22 effects parallel displacement in unison of the shafts 16 towards and from the shaft 1, and by varying the speed of the drum 3 varies the speed of the tail shaft 10. Frictional pressure in the friction gearing is maintained by axial thrust upon a bearing 7 exerted by a pair of levers 30, Fig. 2, pivoted at 29 on the frame 18 and acted on at their upper ends by thrust pins 31 engaged by a pair of bell-crank levers 32, Fig. 5, the long arms of which are drawn together by a spring 33.
