Filed: 1937-09-07
Abstract: 486,638. Dental syringes. HAGEMEIER, H. Sept. 7, 1937, No. 24422. [Class 81 (ii)] [Also in Group XXVIII] A syringe, particularly employable for injecting cement into tooth cavities, comprises a screw-threaded plunger rod 17 carrying a nut 19 engaged by a bifurcated lug 16 on a pivoted handle grip 13, operation of which presses forward the plunger 26 through a short stroke to expel a portion of the syringe contents. The nut 19 is returned by a spring 21, whereafter the plunger rod may be fed forward by turning a milled head 23 to set the syringe for a further stroke, the contents thus being extruded in successive steps. The rod 17 rests in a socket 28 in a ball joint 27 on the plunger 26, or may rest against the plunger itself. The grip 13 co-operates with a second grip 14 which may be integral with, or pivoted similarly to grip 13, to, the syringe body. The plunger 26 works in a barrel 10, or in a capsule 24, introduced into the barrel through the end thereof or through lateral openings therein, and secured by a screw-ring 11. A nozzle 12 having a cranked portion is adjustably rotatable in a part 12<1> secured as by screwing to the capsule 24 or the barrel 10.

A packet containing a batch of articles such as cigarettes and arranged to be opened at one end to give access to the articles, contains a composite inner wrapper, e.g. of foil consisting of two parts 1, 2 partially overlapped at 3 and stuck with limited adhesion at 4 so that the parts may be treated as integral when folding the wrapper around, for example, 20 cigarettes but are easily separable so that one part can be readily pulled out of the packet to expose one end of the cigarettes. The adhesive may be of a kind that loses its adhesive properties with time so that the parts automatically become unstuck.

Abstract: 870,516. Electric remote-control systems. DREHMASCHINENWERK LEIPZIG VEB. Aug. 2, 1957, No. 24486/57. Drawings to Specification. Class 40 (1). In an electro-mechanical remote-control system for continuously variable hydraulic pumps or transmissions comprising a shiftable member for varying the delivery volume or output speed, the displacement of this member is effected by a geared servomotor controlled by electric means comprising a master potentiometer and a controlled potentiometer operated by the geared servomotor, the electrical circuit incorporating a two-way centre zone relay in a bridge circuit, and a contactor causing the servomotor to run when the bridge is unbalanced until balance has been restored. The displacement of the shiftable member is effected through a threaded spindle and nut, and a clutch is incorporated in the motor drive shaft and controlled by a hand lever for disengaging the reduction gearing of the servomotor from the motor drive shaft for the purpose of changing over to auxiliary manual control by a hand wheel mounted on the spindle. The controlled potentiometer is preferably driven from the drive shaft through a gear tain, a gear-wheel carrying a scale to provide a dial being directly connected with the controlled potentiometer. The master potentiometer may be housed in a casing separate from the switch box containing the other electrical control elements and be built into a control panel.

Title: Process for the activation of carbon and the production of carbon bisulphide
IPC: C01B32/336
Filed: 1926-10-05
Abstract: 283,267. Carpmael, W., (I.G. Farbenindustrie Alst.-Ges.). Oct. 5, 1926. No Patent granted (Sealing fee not paid). Charcoal.-Carbon is treated at elevated temperature with the vapour of sulphur or of a compound yielding sulphur whereby the carbon is actuated and carbon bisulphide, may also be produced. The properties of the active, carbon may be controlled by the choice of raw material, time of activation and the concentration of the sulphur vapour which may be diluted with an inert gas such as nitrogen. The process may be carried out in externally heated retorts, or in apparatus heated internally electrically, or the necessary temperature may be maintained by superheating the sulphur vapour. A shaft or rotary furnace may also be employed and the process conducted continuously. Reference has been directed by the Ccmptroller to Specification 270,505.

IPC: E04C2/26
Filed: 1964-06-15
Abstract: A rigid flat sheet is composed of a fibrereinforced polymeric constituent consisting of a major proportion based on one or more from methyl methacrylate, acrylonitrile and styrene and a minor proportion of a vinyl chloride polymer, the fibres being uniformly dispersed throughout the sheet and all lying in or substantially in the plane of the sheet.
