The head 13 is of sandslinging type fed from a hopper 24 by a belt conveyer 26 driven by a motor 27 which also drives the head. The slide 14 is reciprocated beneath the head and moved to an unloading station 41 by the twin hydraulic rams 39, 40. A slide 114 is similarly actuated, each slide carrying hand-operated means 42, 142 to raise a completed mould off its pattern. Automatic loading and unloading means may be provided at each side of the machine. A motor and pump 43, 44 for supplying hydraulic fluid can be withdrawn along rails 45 through a door 47 for servicing. Wires 50 are carried on vertically adjustable brackets 51 to strickle the sand as the moulds are withdrawn. In operation, the mould box makes several reciprocations for each stroke of the head and the operation is finished by the operation of a valve either by a timer or the operator. The strokes of the reciprocations are determined by switches operated by the movements of the head and box.

Title: Improvements in and relating to glue applying apparatus
IPC: B31B50/62
Filed: 1964-04-07
Abstract: 993,620. Coating apparatus. EMHART CORPORATION. April 7, 1964 [May 1, 1963], No. 14255/64. Heading B2B. A glueing apparatus comprises a nozzle connectible with a source of fluid glue under pressure and has means for selectively permitting and cutting off flow to the nozzle, the nozzle being provided with at least one glue discharge orifice, and means for supporting the nozzle in engagement with a surface to which glue is to be applied but with the orifice spaced slightly from the surface, whereby upon relative movement of the nozzle along the surface, a line of glue can be placed on the surface which line will end abruptly when glue flow to the nozzle is cut off. Preferably the nozzle is provided with an elongated manifold chamber having a plurality of orifices and an elongated spoolshaped plug is disposed in the manifold to confine the flow of glue to a path around it from the source to the orifices. In the embodiment shown a glue nozzle assembly 10 consists of a support arm 16 biased by spring 20 so that the nozzle head 12 normally engages a moist pad 22 associated with reservoir 24. In operation the head 12 is moved to the full line position by the flap F e.g. of a carton to which glue is to be applied. The orifices in the head 12 are so angled that with the head 12 in contact with the flap F there is a small space between the orifice and the flap surface. A valve 14 close to the head 12 controls the flow of glue thereto and has a glue inlet at 30. Flow through the valve is controlled by a spool-like valve member which is supported and moved between open and closed positions by flexing diaphragms moved by compressed air under the control of a solenoid operated pilot valve. The solenoid is operated by feeler contacts in response to the position of flap F passing through the apparatus.

Title: Anchor bolt
IPC: F16B13/08
Filed: 1976-04-08
Abstract: A screw device, used in particular for screwing wooden parts, has a stepped bolt, provided at one end with an external thread, and an expanding dowel (8) which is provided with a threaded bore (10) and an even number of tines (11). The latter are bent in an arcuate manner in cross-section and, at their free end portions, are delimited by an inner surface widening conically towards the free tine ends, with the result that said free ends of the tines (11) form chisel-like cutting edges. These cutting edges extend over the same central angle, as does the remaining, principal portion of the tines (11). When using the screw device, the bolt is screwed into the expanding dowel (8) until the latter is expanded to such an extent that the inclined inner surfaces of the free tine ends run approximately at right angles to the axis of the bolt. <IMAGE>

Title: Pressure safety devices
Inventor: PHILIP THOMAS BRUCE
IPC: F16K17/16
Filed: 1953-05-22
Abstract: 748,953. Pressure-relieving devices for fluids. DISTILLERS CO., Ltd. May 13, 1954 [May 22, 1953], No. 14411/53. Class 135. A safety device for pressure vessels which is particularly adapted to operate at relatively low pressure differentials comprises a frangible diaphragm 1 of a relatively weak material located in the fluid escape path from the vessel and supported on its side remote from the fluid in the pressure vessel by a weakened dome-shaped disc 2 of material having a relatively good creep resistance. Examples of relatively weak material are aluminium and lead foils and films of organic plastics such as polyethylene, polytetrafluoroethylene, and polychlorotrifluoroethylene. Suitable materials for the dome-shaped disc 2 are stainless steels, nickel, and nickel alloys including that known under the Registered Trade Mark " Monel " metal. The disc 2 may be weakened by grooves, recesses or the like but preferably by perforations along diametral lines AA, BB, CC of potential rupture. Additional lines of perforations 8 may be provided along which the sectors of the disc 2 fold back when the disc is ruptured. Alternatively the perforations may be replaced by narrow slits running along the lines of potential rupture. The inner diaphragm 1 may initially be flat and allowed to assume a shape in conformity with the disc 2 under the pressure within the pressure vessel. Preferably, however, the frangible diaphragm 1 and its dome-shaped support correspond in shape. They may be fitted separately in the safety device but preferably they are permanently attached at their annular flanges by bolts or rivets or by bending the annular flange of one over the annular flange of the other. In the case where the frangible diaphragm 1 is of plastic material the two components are bonded together by an adhesive to form a composite frangible diaphragm. As shown, the frangible diaphragm 1 and the dome-shaped disc 2 are held with a clamping ring 3 between a pipe section 4 attached directly to the pressure vessel and a pipe section 6 open to the atmosphere.

Abstract: 1,089,022. Blood sampling means. J. VILLAUME. April 6, 1965 [April 9, 1964], No. 14469/65. Heading A5R. [Also in Division B8] In means for taking a sample of blood, for transporting the sample and for serving as a centrifuging tube when the sample is centrifuged, a tube (or sachet), adapted to be manually resiliently compressively deformed, has a closed end and an open end which is stiffened so as to resist such deformation. The tube is in combination with at least two alternative stoppers each adapted for sealing engagement with the open end of the tube, the first of the stoppers being provided with a hypodermic needle to enable a sample of blood to be drawn into the tube on release of manual pressure thereon, the second of the stoppers being adaptod to replace the first stopper to seal the tube for transport and for centrifuging the sample. The tube and stoppers are made of a resilient plastics material, for example polyvinyl chloride. As illustrated in Figure 1; tube 1 has a closed end 1a, which serves as a convex hemispherical base for locating the tube in a centrifuge, and an open end 1b externally reinforced by longitudinal ribs 5 and having a shaped rim 1c to provide a seal with a stopper. The tube may have reference marks 6 for taking a sample of the required volume. Stopper 2, which is provided with circular ribs 2a to give a seal with the tube and with a lug 7 to facilitate removal from the tube, carries a hypodermic needle 3 which may have been moulded into the stopper during manufacture. The.second stopper either may be in the form of a simple plug, Figure 4 (not shown), or may be hollow and serve to contain an anticoagulant for adding .to the blood sample to prevent coagulation, Figure 3 (not shown); both the plug stopper and the hollow stopper may be provided. In the embodiment of the invention illustrated in Figure 5, the tube 12 has a flat closed end 12a, the domed head 14a of stopper 14 providing the convex hemispherical base; the convex base, whether formed by the end of the tube itself or by a stopper, may be weighted. The means preferably is initially provided in a sealed pack, having been sterilised therein by ionising radiation.
