Title: Improvements relating to the continuous casting of metals
IPC: B22D11/08
Filed: 1969-04-25
Abstract: 1,208,236. Continuous casting machines and processes. CONCAST A.G. and SCHLOEMANN A.G. 25 April, 1969 [29 April, 1968; 21 May, 1968], No. 21363/69. Heading B3F. In a continuous casting process where melt is poured into a tubular mould which is blocked by a starter head having a projection about which the melt solidifies, the casting is withdrawn from the mould by the starter head and separated from the starter head by tilting or rotating the longitudinal axis of the starter head out of alignment with respect to the longitudinal casting axis. In the Figure, the starter head 3 of a starter bar plugs a mould 1 and is connected to a starter bar by a hinge 49. The head 3 has top faces (16), 17 inclined with respect to the casing axis and a recess which terminates at an inclined plane 22 extending into the head along the mould side 6. The mould is sealed with asbestos fillets 26. Within the recess the starter head is provided with a semi-cylindrical projection 5. The melt then solidifies in the starter head in the form of a hook, and separation of the casting and starter head is effected by pivoting the starter head about a point 27.

Title: Improvements in safety pins
IPC: A44B9/18
Filed: 1920-07-20
Abstract: 166,052. Schenk, E. July 20, 1920. Catches and sheaths for hinged pins; hinged joints for pins.-A safety-pin or brooch-pin is provided with means for automatically locking its point comprising a catch member and a spring bolt, the bolt being retained in its drawn-back position by the catch member as long as the pin is open and moving automatically under the action of its spring so as to lock the point of the pin as soon as this attains its closed position, and the spring of the bolt being compressed in the action of releasing the pin. Fig. 3 shows a form in which the bolt e, provided with a flange f, slides back against the action of the spring g and is held in its open position by means of a projection m on the catch k. The catch k consists of a leaf-spring fixed at one end and at the other carrying a half-tube l, which acts as a guide for the pin. On closing the pin, the tube l is depressed, causing the bolt to be released. Fig. 7 shows a form in which the bolt e<1> is formed by a rod-piston sliding in a socket g<1>. At the free end of the rod of this piston is fixed a hollow plug f<1>, which fits on the socket g<1>. The socket g<1> is cut away at the top for the passage of the pin and at the bottom for the reception of the catch member k<1>, which operates similarly to the catch k shown in Fig. 3. Fig. 10 shows a form in which the bolt member e<2> is carried by a cylindrical slide, within which is mounted the spring i<2>, At the other end, the slide has a circular notch m<2>, which, when the pin is opened, is engaged by the circular part of the head of the pin and thus locks the bolt in its open position. Fig. 11 shows a similar form in which the head of the pin is provided with teeth m<3> which engage the rack cut in the slide r<3>, so that the brooch may be opened by pressing on the button f<3>, and so that first the bolt is released and afterwards the pin turned.

[Also in Group XL (c)] A variable electric component such as a resistor is housed within a hermetically-sealed container and is adjusted from outside the container by arranging that a portion of the wall of the container be flexible to permit a mechanical transmission to be effected through the wall of the container without any coupling actually penetrating the wall. The container may be evacuated or alternatively filled with air or another gas under pressure. In the arrangement illustrated the container 13 is a bellows construction, rotation of the knob 20 causing movement of the upper surface of the container and hence rotation of the shaft of the variable resistor 16 through a rack-and-pinion gearing 24, 25. Other forms of gearing both between the manual actuating member and the movable wall of the container and between the said wall and the shaft of the variable component are also described. Furthermore it is also stated that the container need not be of bellows construction; it may instead comprise rigid side walls but have a flexible end wall.

Abstract: 734,202. Hose couplings. ENGLISH ELECTRIC CO., Ltd. Aug. 21, 1953 [Sept. 5, 1952], No. 22381/52. Class 99 (1). In a coupling for connecting flexible, fluidconveying hoses to apparatus in which the fluid is used, a body portion 1 having selfsealing fluid joints 2 is provided with a latch 4, e.g. a T-piece carried on a shaft 3 extending through the body, engageable with the apparatus, and there is means which causes relative movement between the latch and the body and sealing of the joints with corresponding joints on the apparatus, and means for remotely initiating the operation of an actuator, e.g. a lever 9 slidable on a splined portion 8 of the shaft 3, which releases the latch and is operated by the fluid conveyed. As shown, a knob 5 rotates the shaft 3 to orientate the latch 4 when the latter has been passed through a slot in the apparatus and the joints 2 have been aligned with those on the apparatus. A hand wheel 6 on a threaded portion of the shaft is tightened to force the body against the apparatus and engage the joints 2 and to compress a spring 17. Release of the coupling is effected by energizing a solenoid which causes a valve to connect the high-pressure side of the fluid supply to a cylinder in which a piston 11- is moved against the pressure of a spring 12. A plunger 10 attached to the piston actuates the lever 9 which rotates the shaft until the latch 4 becomes disconnected from the slot in the apparatus thereby permitting the coupling to be ejected under the action of the spring 17. In a modification, relative movement between the latch and the body during coupling is caused by a motor powered by the pressure fluid and under the control of a manuallyoperated valve.
