Title: Embossing or cutter crush presses
IPC: B41F1/02
Filed: 1930-01-24
Abstract: 346,065. Embossing-presses. CAMPBELL, J. D., 54, Marlborough Road, Forest Gate, London. Jan. 24, 1930, No. 2469. [Class 100 (ii).] In a press for cutter-crush embossing, operated by toggle mechanism C, the depth of embossing can be varied by means of a bush D screwed into the upper fixed part of the press and forming a cylindrical housing at its lower end to receive a spherical end on the upper link of the toggle. The upper link C<1> is situated centrally between two links C2 forming the lower part of the toggle, and the adjacent parts of the links are formed with spherical seatings to accommodate similarly shaped parts on a pivoting bar E. As an alternative, the upper link may be slidable on the bar E so that it automatically takes up a position for the even distribution of the pressure. The ends of the lower links C<2> removed from the bar E are formed spherical in shape and are loosely housed in cylindrical borings K in the movable member F of the press which is normally supported by springs I engaging side extensions thereof. The extensions slide in slotted extensions of the bed H and may be rectangular or circular in section, the latter form permitting pivotal movement of the member F. The toggle mechanism is operated by a hand-lever G through links B, and a stop is provided to prevent it passing beyond the vertical position.

Filed: 1938-01-26
Abstract: 491,193. Machinery guards. MANSFELD, C. G. H., and MANSFELD, K. H. W., (trading as MANSFELD, C., [Firm of]). Jan. 26, 1938, No. 2483. Convention date, June 3, 1937. [Class 80 (iv)] In foot-operated platen presses the treadle 8 is locked in the engaged position by a catch 16 connected to the guard bar 24, and is released if a hand comes in contact with the bar. When the treadle is depressed a clutch operated by a shaft 7 is thrown in, the bar 11 moving to the left until a stop 17 passes the catch 16 which thereupon falls to lock the bar 11 and treadle. The platen 1, driven by a rotating crank-pin 2a moves to the right. If a hand strikes the bar 24, bell-cranks 21, 19, are turned, the catch 16 rises and the clutch is thrown out by a spring 13. During its passage a cam face on the platen strikes a roller 28 on a bell-crank 26 raising a rod 25 to hold the treadle raised during the last part of the stroke ; alternatively, the treadle may be held by an electromagnet energized by a switch closed by the platen. In Fig. 5, is shown means for holding the treadle even after the solenoid 31 is dead, so long as the clutch is in. When the treadle is depressed a detent 37 catches behind an arm 38 pivoted to the rod 30 and rigid with the treadle, and bears with a nose 39 on a key 40 on the rod 11. When the rod moves to the disengaged position the key 40 lifts the detent so that the treadle can be depressed when the solenoid is de-energized.

Patent GB-824972-A (GB)
Title: Silica fiber and method of making
Inventor: LABINO DOMINICK
IPC: C03C25/68
Filed: 1957-01-26
Abstract: Silica fibres (containing about 99% silica, or, as in one example, at least 99.9% silica) are produced from fibres having diameters of less than about one micron (particularly 0.01 to 1.0 micron) made from a glass consisting essentially of silica and alkali metal oxide in a weight ratio of about 4 to 1 and leaching the alkali metal oxide from the fibres to leave essentially silica and chemically combined water. The chemically combined water may be removed by heating to about 1000 DEG  F., leaving substantially pure silica in fibre form.  A particular glass from which the fibres are made consists of about 78.2% silica and 21.8% sodium oxide.  The leaching agent may be (hot) water, a mineral acid solution, or an aqueous solution of ammonium chloride to which a small amount of H2PtCl6 may be added.  The leached fibres may be dispersed in water and then flowed on to a screen to form a felt.  When pressed the fibre forms a paper which may be used for electric or heat insulation or as a screen for repelling the effects of radiation as in nuclear units.
