Title: Process of manufacture of multi-cellular glass
IPC: C03C11/00
Filed: 1935-05-28
Abstract: 447,805. Glass manufacture. SOC. ANON. DES MANUFACTURES DES GLACES ET PRODUITS CHIMIQUES DE St.-GOBAIN, CHAUNY, & CIREY, 1<bis>, Place des Saussaies, Paris. May 28, 1935, No. 15534. Convention date, May 28, 1934. [Class 56] A process for the manufacture of multicellular glass consists in heating a mixture of crushed glass with one or more powdered substances which emit gas or vapour at the temperature at which the glass particles become fused together. The emission of the gas or vapour causes the plastic mass to expand, the expansion being stopped when the mass has increased its volume in the desired proportion to obtain a predetermined density. The added material may consist of a reducing substance such as carbon, a carbide (particularly carborundum), or silicon or a ferro-silicon. If the substance is added to crushed glass containing a sulphate and the mixture is heated to 800-900 C., the reducing substance decomposes the sulphate to produce bubbles of gas which remain occluded in the plastic mass. In another method, powdered silica, sodium sulphate, and carbon are mixed with crushed glass and heated to 850 C. Talc, kieselguhr, or other diatomaceous earth may also be used.

Title: Improvements in current-responsive automatic electric circuit-breakers
IPC: H01H73/30
Filed: 1950-06-26
Abstract: 688,649. Automatic circuit-breakers. MARCOZ, J. A. E. June 26, 1950 [July 6, 1949], No. 15901/50. Class 38(v) In a trip-free circuitbreaker, the movable contact is biased towards the "open" position by a spring and towards the "closed" position by a stronger spring, a connection between the two springs being released by a bimetallic strip to trip the switch and a resetting push-button indicating whether the circuit-breaker is open or closed. In Figs. 1 and 2, the moving contact 2 is biased towards the open position by the blade spring 3 on which it is mounted and is normally held in the closed position by the stronger blade spring 5. The two blade springs are connected by a latch 6 which is moved aside by the bimetallic strip (not shown) to trip the breaker. Alternatively the latch 6 itself may be a current-responsive bimetallic strip. The switch is reclosed by depressing the push-button 4, so moving the strip 5 downwards until its end engages under the latch 6. On release of the push-button 4, the spring 5 moves the spring 3 upwardly until the contacts 1, 2 reclose, the arrangement ensuring that the contacts cannot be held closed by the push-button if an overload exists. In Fig. 3, the bimetallic strip 10 is secured between the spring 3 and a C-shaped contact and latch member 2, 6. When the strip 10 is heated sufficiently by the current flowing through it, it withdraws the latch 6 allowing the spring strip 3 to open the contacts 1, 2. The - switch may be opened manually by depressing a push-button 12 which acts on a member 14 fixed to the blade 5 to disengage a catch 7 from the latch 6. The current-setting may be altered by a screw 15 which adjusts the relative position of the catch 7 with respect to the latch 6. Contacts 18 in an indicator circuit are closed when the main contacts are tripped open. In a modification Fig. 6 (not shown), the stronger spring is in the form of a helical spring acting on the push-button 4 to which the opening spring blade is latched. In Fig. 7 (not shown) the fixed contact-carrying member is adjustably mounted and carries the bimetallic strip which actuates a latch member pivotally mounted on the spring strip 3. Specification 498,376 is referred to.
