Title: Improvements in or relating to moulds for casting stereotype printing plates
IPC: B41D3/00
Filed: 1936-07-22
Abstract: 478,956. Cooling engines &c. HOE & CO., Ltd., R. (Hoe & Co., Inc., R.) July 22, 1936, No. 20313. [Class 29] [Also in Group XVI] In order to control the cooling of the core of a stereotype, mould a circulation system, enabling fluid heated in the core to be returned thereto together with fresh fluid, is provided with a mixing- valve wherein fresh fluid is injected into a conduit leading from the outlet to the inlet of the space in the core for cooling- fluid. The valve is provided with a chamber connected to the conduit, a, second chamber receiving the supply of fresh fluid, and an adjustable member permitting fresh fluid to be injected into the chamber connected to the conduit. As shown, the mould comprises a core 12 and a matrixreceiving part 13 having cooling-chambers provided with inlets and outlets 16, 18 and 17, 19 respectively. Cooling-fluid enters the system through a pipe 21 and passes to the mixing-valve 22 through a manually-controlled valve 26 or a solenoid valve 27 which is actuated from a thermostat 28 on the core 12. After passing the valve 22, fluid flows through a pipe 30, three-way cock 31, and a pipe 32 to the inlet 16. The outlet 17 is connected to a waste cock 33 and the conduit 36 leading back to the valve 22 and to a pipe 37. The fluid flowing through the pipe 37 is led to the inlet 18 of the mould part 13 and thence through pipes 41, 44 to a waste pipe 45. The fluid flowing to the valve 22 mixes with the fresh fluid entering from the pipe 21 and is passed back to the pipe 30, so that the fiuid in the mould core is cooler than that in the part 13, the difference in temperature depending on the setting of the valves 26, 27. and cock 33. The cock 31 enables the system to be drained. The valve 22 comprises a chamber 62 into which fluid from the pipe 21 enters, this chamber being provided with an outlet controlled by a valve 67 and leading to a second chamber 63. The conduit 36 and the pipe 30 leading to the inlet 16 are connected to the chamber 63.

Title: A multi-curve graphic recorder
IPC: G01D15/14
Filed: 1960-06-09
Abstract: 944,595. Phosphorographic delay devices. G. VERNOIS. June 9,1960 [June 13,1959], No.20350/60. Heading G1A. A delay device comprises a recording device by which information is recorded on a moving layer of a phosphorographic substance and a reading device capable of recovering the recorded information. The phosphorographic layer is arranged on the external surface of a tubular cylindrical element 1 rotatable about its axis at a controllable rate. For recording, a fixed mask 3 is positioned to define a slit parallel to the cylinder axis and light from lamp 11a reflected from mirror 10a, pivoted about a vertical axis and moved by a galvanometer in accordance with the incoming signal, is directed through the slit to the recording surface. The position along the length of the slit at which the light impinges on the surface is dependent on the signal applied to the galvanometer. At a time delay dependent on the speed of rotation of the cylinder the record made reaches the fixed readout slit 7 also arranged parallel to the axis. Most phosphorographic substances require irradiation with infra-red in order to cause the part of the layer on which light has fallen to give a light output and it is necessary to direct infra-red energy on to the layer along the generatrix opposite slit 7. As shown this is done by using a filament source 4, concave mirror 5, and screen 6 inside the cylinder. Where the phosphorographic substance is such that the recorded light path is a visible track these units are not required. A photo-cell arrangement 12a is positioned opposite the slit and is arranged in known manner to automatically position itself along the slit opposite that part of the drum surface radiating luminous energy. An output can be derived from this arrangement as required. Fig. 2 shows how two signals correspond ing to two parameters of a condition under investigation can be recorded on a single record tape 14 fed between drums 14a and 14b at a constant rate. One signal, controlling galvanometer mirror 10, causes movement of a beam of light from lamp 11 along a line perpendicular to the drawing. The position of the beam along this line is sensed by an automatic following photo-cell arrangement such as that at 12a and the movement of the arrangement recorded by the device schematically shown at 13. The other signal is applied to control galvanometer mirror 10a and is delayed by the delay device a time equal to that taken by tape 14 to travel from recorder 13 to recorder 13a. The latter is moved in accordance with the position of arrangement 12a and gives a recording correctly placed with respect to the one already present.
