Abstract: 210,721. Hazel-Atlas Glass Co., (Assignees of Oliver, G. G., and Stenhouse, T.). Jan. 31, 1923, [Convention date]. Annealing - furnaces; charges, conveying.- Glassware is conveyed through an annealing leer on suspended carriers 2 which support one or more trays 8 for the ware, the carriers being moved successively through entrance, annealing and cooling zones. Each carrier is suspended by a plate 10 passing through a slot 9 in the leer roof from the lower flange of an overhead I-beam 15 situated in a chamber above the leer, the plate 10 being extended to form two pairs of brackets 12 which carry the runner wheels 13. Escape of heat through the slot 9 is minimized by flange members 11, and these are extended beyond the plate 10 at one end to form a V-notch 11<a> in which engages the projecting portion 10<a> of the plate of the next carrier. Mounted on the upper flange of the beam 15 is a reciprocating frame consisting of yokes 18 and angle bars 17 carrying pawl members 16, which are so pivoted that they will engage behind a plate 10 when the frame is moved in one direction, while on the reverse strode they slide over the plate, the pawls being positioned for the next forward stroke by spring-mounted stops 28. The stroke of the frame is preferably twice the length of a carrier. The entrance, annealing and cooling zones are separated by swing doors in relation to which the pawl members are so positioned that a clear space is always maintained for the opening and closing of the doors.

Title: Improvements in or relating to die casting machines
IPC: B22D17/14
Filed: 1961-04-06
Abstract: 928,100. Casting-machines. DIE CASTING MACHINE TOOLS Ltd., and A. R. MILLS. April 3, 1962 [April 6, 1961], No. 12392/61. Class 83 (1). In a pressure die casting machine evacuation of the die cavity is effected in conjunction with the injection operation, whereby a piston 22 within cylinder 23 is controlled for injection and return movements of plunger 21, to which it is attached, by admission of a pressure medium via pipe 24 and valve 25 alternately to each side of the piston 22. Connected to cylinder 23 is a pressure responsive switch 30 so that when a given pressure is reached within cylinder 23 to promote a downward injection movement of the plunger 21, this same pressure closes contacts 32, 33 within switch 30 which then energizes a solenoid coil 35 of a valve 29 which lifts movable valve member 36 from its seating which permits the evacuation of the die cavities by extraction pump 28 via reservoir 27. At the end of the injection stroke of the plunger, pressure is applied to the other side of piston 22 to return said piston to its original position. This creates a pressure drop in relation to the switch 30 which breaks contact and permits the closure of the valve 29 to cut off the die evacuating means.

Filed: 1975-03-26
Abstract: 1502372 Asbestos laminate CARL MUNTERS AB 26 March 1975 [9 April 1974] 12636/75 Heading C1A [Also in Divisions B1 B5 and F4] A contact body is made from an assembly of hydrated asbestos fibre layers, bearing against one another at spaced positions to form through channels and coated or impregnated with at least one inorganic substance for mechanically strengthening the finished body, by passing a hot gas current through the channels to dehydrate the asbestos by releasing water of crystallization. The treatment time may be less than 1 hour. The gas, e.g. air, may be passed through the channels by a fan. The heating may be sufficient to sinter the coating with the dehydrated asbestos residue, and the coating may comprise a mixture of reactive substances (e.g. water glass-CaCl 2 ), silica or Si-Al containing substances. The coatings and methods of Specifications 1,502,373 and 1,502,374 may be used. The water in the coatings is driven off during the heating. Combustion of organic binders and additives in the fibrous layers by the gas current may contribute some of the necessary heat. The body may be a cylinder or rotor-shaped assembly of plane and corrugated papers or all layers may be corrugated with alternate corrugations crossing. Specified uses: moisture and heat exchange, cooling towers, ventilation and drying systems, and catalyst supports.

Title: Safety circuit and apparatus incorporating it
IPC: G05B19/02
Filed: 1974-03-25
Abstract: 1461480 Protective systems GRACO Inc 25 March 1974 [26 March 1973] 13129/74 Heading H2K An electrostatic spray gun protective circuit comprises a resistor connected in series with the spray gun electrode for developing a voltage proportional to the current through the electrode, a control circuit having an input connected to the resistor and an output connected to the high voltage source for the spray gun and which generates a signal when the voltage at its input exceeds a threshold level indicating overload, which signal causes the high voltage source to be switched off, and a time delay circuit and desensitizing means connected to the control circuit to cause the control circuit to respond to the voltage exceeding the threshold level only after a certain time delay after switching on to prevent initial surges from causing the spray gun to be switched off. During the desensitized period the control circuit may be responsive at a different threshold level or switching off of the high voltage source may be prevented. The control circuit comprises transistors 35, 36 and 40 which are switched on when a trigger switch 7 on the spray gun is closed to repeatedly charge capacitor 41 through resistor 46 to cause unijunction transistor 43 to repeatedly fire and send a train of firing pulses to SCR 31 in the supply circuit, thus allowing current to flow to the spray gun. A resistor network 55, 56, 57, 58 is in series with the supply to the spray gun and when excessive current flows the voltage at point 54 on the network exceeds the threshold voltage of unijunction transistor 63 causing it to conduct and pass a positive signal to SCR 59 which causes SCR 60 to fire in turn and cut off transistor 40 which cuts off the train of pulses to SCR 31 and thus stops current flowing to the spray gun. On switching on the spray gun an RC timing circuit 49, 50, 51 desensitizes the control circuit by switching on transistor 48 for a timed period to short out resistances 55, 56 and 57. In a second embodiment, Fig. 5, not shown, a resistance in series with transistor 48 establishes a different overload setting during this timed period. In a further embodiment, Fig. 6, not shown, an additional voltage divider resistor network alters the response of the unijunction transistor 63.
