Title: Improvements in and relating to apparatus for producing casting moulds
IPC: B22C11/10
Filed: 1958-08-19
Abstract: 848,604. Moulding machines. JEPPESEN, V. A. Aug. 19, 1958 [Aug. 30, 1957, Sept. 17, 1957], No. 26611/58. Class 83 (1). A method of producing moulds consists in compressing the moulding material in a chamber 5 between pattern plates 11, 12, and subsequently pushing the mould out of the chamber by one of the plates, the moulds forming a continuous series ready for pouring. The moulds are guided between channel sections 2, 3, adjustably mounted on a base 1 and containing cooling passages 18. Moulding material is blown into the chamber from a blower 8 supplied by a conveyer 9. The chamber is then sealed by a slide 7, and the mould set by CO 2 . The pattern plate 11 is slid away and the mould pushed forward, causing a completed mould at the end of the series to fall on to a knock-out grid. The guiding channel may be closed past the casting section, or may be circular in crosssection as in Fig. 5. A number of channels may be supplied from one chamber, and the pouring ladle 16 may be operated after the production of each mould or after a series have been completed. Cores may be inserted between the moulds.

Abstract: 426,122. Propelling-pencils. LEISTENSCHNEIDER, A., 5, L³tzowstrasse, Diisseldorf, Germany. Sept. 27, 1933, No. 26651/34. Divided out of 426,060. [Class 146 (iii)] In a propelling-pencil of the kind comprising a magazine for leads, an internal leadcarrying tube adapted to receive leads from the magazine and to be pressed forwardly by hand operation of the pencil cap and returned by spring pressure, a clamping- device carried by the tube and adapted to be closed to grip the lead during the forward movement of the tube while being released during the return movement thereof, and a slidable clamping - ring adapted to engage abutments in the pencil casing at each end of its travel, forward movement of the clamping- device relatively to the ring when this is at the forward end of its travel causing the release of the device, and rearward movement of the clamping - device relatively to the ring when this is at the rearward end of its travel causing the closing of the device, there is provided means for facilitating the entry of the leads from the magazine to the lead-carrying tube, comprising means in association with the magazine which are adapted to execute a movement within the lead-space of the latter during movement of the pencil cap to impart a movement to the leads within the space. The cap 6 is attached by screw or resilient locking means to a slidable sleeve 3 which forms the magazine and in one modification carries a member 8, the sleeve 3 and member 8 being movable relatively to the lead-carrying or guide tube 12, the limits of such movement being fixed by the stops 13, 14 and shoulders 15, 16. The end of the tube 12 is formed shovel-shaped, so that on pressing the cap, the end 17 is projected into the magazine and separates one lead for feeding to the pencil tip. Alternatively, the fixed outer casing may carry spring members which project through slots into the magazine tube so that upon pressing the cap, the magazine tube, and the lead tube which is fixed thereto, move downwards, and deflect the spring members to impart a movement to the leads in the magazine, whereby one may be separated and caused to enter the end of the lead tube. In a further modification, the end of the magazine tube is attached to the upper end of the lead tube, by flaring out the latter into a flexible diaphragmlike member which is attached to the end of the magazine tube, so that when the latter is depressed by pressure on the cap, the lead tube moves upwards relatively to the guide tube, changing the inclination of the base of the magazine and shaking up the leads.

Abstract: 675,676. Automatic voltage control. ASSOCIATED ELECTRICAL INDUSTRIES, Ltd. Aug. 29, 1950 [Oct. 27, 1949], No. 27595/49. Class 38 (iv). In a voltage stabilizing system the supply to be stabilized is applied to the cathode 5 and the accelerating electrode 8 of an electron gun and the beam is focused on to a bisecting electrode 10 at the entrance of a spectrometer-like arrangement 11 subjected to a constant magnetic or electrostatic field. The beam follows an arcuate path and is intercepted by an electrode 13 to an extent dependent upon the radius of the path and therefore upon the magnitude of the accelerating voltages. The current received by electrode 13 is applied to a triode 17 connected across the load 1 so as to modulate the supply from source 2 in a manner to oppose changes in the supply voltages. The electrode 10 intercepts approximately one half of the beam and the image of the " halfspot " so formed is focused on to the electrode 13 which is formed as a knife edge, with the straight edges parallel with and slightly overlapping the " half spot " In a modification, the part of the electron beam which spills over the electrode 13 presses across a gap to a further beam correcting electrode connected to the grid of the triode. In another arrangement, wherein higher gain is obtained, the triode is replaced by an electron multiplier, the electron beam of the multiplier itself effectively loading the circuit.
