Title: Improvements in or relating to safety devices for apparatus for opening doors
IPC: E05B47/06
Filed: 1932-08-25
Abstract: 391,012. Door-operating appliances. BERTELE, R., 3, Stradone Duomo, Verona, Italy. Aug. 25, 1932, No. 23801. [Class 65 (i).] In a door-operating appliance having a detent operated electrically, the circuit which operates the detent is only closed when a signalling circuit, adapted to be closed from the outside when the door is required to be opened, has been closed. In the arrangement shown, P is a part of the door-operating mechanism which is normally held against movement by a spring-controlled pivoted detent L held in engagement with the member P by the armature of an electromagnet E. The circuit of the electromagnet E, controlled by a pushbutton t, includes contacts a, normally open, operated by a spring-controlled crank R which is held in the position shown by the armature of a second electromagnet e. Pressing the pushbutton t therefore has no effect unless a button s has been pressed to energize the electromagnet e, the circuit of which also includes a signal bell V ; energization of e releases R to close contacts a, and if the button t is now pressed the electromagnet E is energized and the detent L is rendered free to be pushed aside by the member P of the dooroperating mechanism. When the member P moves, the detent L is forced against the crank R so that the latter again engages the armature of electromagnet e and allows the contacts a to open. The detent L is restored to its locking position, in engagement with the armature of electromagnet E, by its spring. In a modification, the contacts a are dispensed with and the crank R is arranged to hold the armature of electromagnet E in the normal position.

Title: Electrostatic separation of alkali metal salts from ore
IPC: C01D3/08
Filed: 1952-09-24
Abstract: Potash ores (e.g. Sylvinite, Langbeinite) are concentrated by (i) heating the comminuted ore to between 575 DEG  to 1300 DEG  F., (ii) inducing a differential electrostatic charge to the ore as it cools (e.g. by rubbing contact with a grounded plate), and (iii) passing the heated charged ore through an electrostatic field as it cools to between 425 DEG  to 100 DEG  F.  Optimum separation takes place between 150 DEG  to 250 DEG  F.  A charge may be applied to the ore by a vibratory shoot which imparts different electrostatic charges to the halite and sylvite particles.  Five examples of the treatment and concentrates obtained are given.

Title: Improvements in or relating to stokers of the stepped reciprocating firebar type
IPC: F23K3/08
Filed: 1949-09-21
Abstract: 678,565. Furnace grates. MARTIN, J. J. Sept. 21, 1949 [Oct. 1, 1948], No. 24216/49. Class 51 (i). In a stoker of the stepped reciprocating firebar type protuberances in the form of right prisms or truncated oblique prisms are provided on the upper longitudinal surface at the head and transversely of all or some of the moving firebars, said protuberances being arranged in such a manner that, when the firebars are in their operative positions, one lateral face of each protuberance is approximately vertically disposed, or is inclined so that the top edge of said face overhangs the junction of said face with the top surface of the firebar, a plurality of such faces acting substantially on every return stroke of the pertaining firebar or when the distance between the top ends of adjacent firebars decreases due to relative movement therebetween. The invention is shown applied to the firebars 1 of an " advancing stoker, Fig. 1, having a main stoking action towards the clinker discharging end of the grate and to an " inverse " or "backward pushing" stoker, Fig. 2, in which the main stoking action is towards the feed end of the grate, the protuberances being shown applied to firebars 1 having pusher surfaces 5 partly at right angles to the longitudinal axis of the bars, and partly bevelled, Fig. 5, or having pusher surfaces 5 wholly at right angles to the longitudinal axis of the bars, Fig. 7. The pusher surfaces may protrude or be bevelled off, Fig. 9 (not shown). In the embodiment shown in Fig. 1 in which the distribution of protuberances is such that they increase in number from the middle of the stoker to the head thereof, the other end of the grate having no protuberances, Fig. 2 (not shown), the main action of the latter is, on the return stroke, to convey small incandescent fuel particles backwards, improving ignition in the fuel bed. In the embodiment shown in Fig. 3, the protuberances increase in number from the middle of the stoker to the rearward end and have their vertically disposed or steeply inclined faces directed towards the discharge end of the stoker. With this construction there is a return movement of small incandescent fuel on the conveying action of the firebars, but the main action, on the return stroke of the firebars, is to move large pieces of clinker towards the discharge end of the stoker. In either embodiment, by giving alternate steps of the stoker opposite movements or by keeping alternate steps stationary, a crushing of coke or clinker agglomeratives is obtained between the protuberances on the bars of one step and the pusher heads of the bars on the alternate step.

Title: Improvements in and relating to the manufacture of filaments and threads
IPC: C08J5/02
Filed: 1934-08-23
Abstract: Fabrics, including lace, are made wholly or in part from threads formed by coagulating aqueous dispersions of natural or synthetic rubber, glue or gelatine having been incorporated with the dispersion or with the coagulant, the glue or gelatine being removed from the fabric as by boiling out.  The proportion of glue or gelatine may vary from 3 to 25 per cent by weight, calculated on the dry rubber content of the latex.  Before incorporation into the fabric, the threads may be stretched in the presence of moisture, from one to several hundreds per cent, and then cooled and dried while stretched. Thus, on removing the glue or gelatine from these threads of the fabric they contract.  Vulcanization and/or dyeing may be effected by the bath removing the glue or gelatine or the dye may be incorporated during the process of adding the glue or gelatine.  Specifications 442,931, 442,935, 442,936, and 443,284 are referred to.
