Title: Multiple cut band knife splitting machine
IPC: B26D3/28
Filed: 1956-09-12
Abstract: 810,516. Splitting machines. FORTUNAWERKE SPEZIALMASCHINENFABRIK A.G. Sept. 12, 1956 [Sept. 14, 1955], No. 27879/56. Class 31 (1). A workpiece 5 is guided towards the cutting edge 6 of a band knife 7 by means of a radially resilient feed roller co-operating with a guide member 2 having projecting portions 31. The feed roller comprises a plurality of disc-like sections each consisting of outer and inner rings 30, 32 and an intermediate ring either of solid rubber 33 or of foam rubber 34. In operation, the portions 31 press the parts of the workpiece to be cut against sections 39 of the feed roller so as to displace these sections eccentrically relatively to the remaining roller sections. The portions 31 may be detachable and may be in the form of rollers.

Title: Improvements in or relating to regulating means for hydraulic presses for thermoplastic moulding materials
IPC: B29C43/00
Filed: 1953-10-12
Abstract: 744,108. Hydraulic moulding presses for thermoplastic materials. TELEFONAKTIEBOLAGET L. M. ERICSSON. Oct. 12, 1953 [Oct. 18, 1952], No. 28000/53. Class 87 (2). Automatic control by means of time relays: A platen 2 is moved, towards and from a fixed platen 1 by a haydraulic ram 3 controlled by a valve 5. This valve is operated manually to close the platens and thus begin an automatic cycle of operation. Another valve 8 controls the supply of heating and cooling media to mould parts 6, 7, this valve being controlled by a crank 26 driven by an electric motor 23 which rotates in one direction only, a half revolution at a time. The time between the end of the first half-revolution and the beginning of the second half-revolution is determined by two time relays 18, 20. Operation: (1) The press being open and the parts being in the position shown, the mould parts 6, 7 being heated by steam from pipe 37, the operator pulls down a gate 9, thereby rocking a lever 15 fulcrummed at 16. This movement of lever 15 reverses hydraulic valve 5, so that ram 3 is raised and the press is closed, and closes electrical contact 17. (2) Closing of contact 17 starts time relay 18, the circuit of which includes a normally closed contact 21; a pause ensues whilst the article is being moulded. (3) Relay 18 times out and moves contact 19 to the broken-line position, thereby (a) starting time relay 20 and (b) making a circuit, through closed contact 24, for a contactor 22. Contactor 22 closes to supply threephase current to motor 23, and the motor begins to turn clockwise, whereupon crank 26 on the motor shaft moves linkage 27, 28 to reverse valve 8, and cold water from pipe 38 passes through the moulds. When the crank begins to turn, the lower end of a link 29 connected to link 27 allows a contact 25 to close, and when the crank has turned through half a revolution the motor is stopped by the opening of contact 24 by the lower end of the link 29. The press remains closed whilst the moulds are being cooled. (4) Relay 20 times out and moves contact 21 to the open (broken-line) position, thereby breaking the circuit of relay 18, which allows contact 19 to move back to the full-line position, whereupon a circuit for contactor 22 is made through contacts 19 and 25. The motor then turns clockwise for a second half revolution until link 29 opens contact 25, as shown; during this half revolution the link 29 rises and rocks lever 15 counter-clockwise to the position shown, the valve 5 being thereby reversed to lower ram 3 and open the press, and the gate 9 being raised. The valve 5 may be such that when it is not actuated by the gate it assumes the pressopen position shown, a slight lifting movement of the gate sufficing to break the press cycle and restore the press to the initial position shown.

Title: Improvements in or relating to counterbalanced supporting mechanism
IPC: F16M11/04
Filed: 1933-10-11
Abstract: 427,474. Counterbalanced supporting mechanism. PIEPER, A. F., 404, West Avenue, Rochester, New York, U.S.A. Oct. 11, 1933, No. 28060. Convention date, Nov. 10, 1932. [Class 52 (v)] [See also Groups XX and XXX] In counterbalancing mechanism comprising an arm mounted to swing vertically on a support and resilient means connected between the arm and the support, one of the tensioning members for the resilient means is moved by engagement with a cam on the support during downward movement of the arm to increase the tension in proportion to the moment of the load at different angular positions of the arm. As shown applied to a bracket for supporting X-ray apparatus the counterbalanced support comprises parallel links 10, 11 pivoted to connecting members 12, 13 the member 13 carrying rotatably the X-ray apparatus 14. The member 12 is rotatably connected to the fixed support 29 by parallelogram linkages 15 .. 18 with connecting members 20, 26 and a link 24 connected between extensions 23, 25 of the links 18, 15. The counterbalancing means comprises compression springs 33 in tubes 32 disposed on opposite sides of the links 10, 11. Rods 34 extending through the springs are provided with nuts 35 for adjusting the tension and have their outer ends pivoted at 36 to the member 13. Collars 40 on the tubes 32 have inwardly-extending pivot members 41 journalled in a bearing 42 connected by a chain 44 with a yoke 43 pivoted a 45 to the member 12. As the links 10, 11 are swung downwardly the chain 44 becomes wrapped round a cam 46 on the member 12 so that the spring tubes 32 are swung successively about the links of the chain and the tension of the spring varied to counterbalance the mechanism in all positions. When the links 10, 11 reach the substantially horizontal position shown in Fig. 7 the bearing 42 is arrested by a stop 47 on the member 12, to prevent the spring passing to a dead centre position across the axis of the link 11. The sections 15 .. 18 of the bracket are locked in any position by a clamp screw 49 extending through the link 17 and engaging a lug 50 on the member 12. Downward movement of the links may be limited by a lug 53 on the link 11 engaging a spring 54 on the holder 13. The X-ray apparatus 14 is mounted on a plate 57 fixed to a hollow rotary member 58, Fig. 3, mounted in a housing 13<a> and provided with slip rings 60 for supplying the current.

Title: Improvements in propellers, pumps and fans
IPC: B63H11/00
Filed: 1928-10-05
Abstract: 324,905. Rees, E. S. G. Oct. 5, 1928. Impeller blades, inward-flow wheels.-Rotary pumps, jet propellers, and the like have impellers with circumferential blades having the forms of rotafoils; a rotafoil is defined as being a blade of the character of an aerofoil but is plotted along the arc of a circle instead of along a straight line. An impeller is shown in Fig. 1 having six rotafoils based on the standard form of areofoil C built on the line AB. The six are spaced equally round the circle D and are tilted to the full line positions D<1> - - D<4> thereby making an angle of incidence of approximately 15. In the modification shown in Fig. 2 a different aerofoil C is employed as the basis. The tails of the rotafoils are very close to the periphery of a stationary ring of blocks in which are formed passages E diverging from the circumference inwards. The fluid passing through the pump enters peripherally between the rotafoils and passes from the trough of each foil through the expanding passages E to an axial discharge. The tail of each rotafoil may have a straight or curved extension F which prevents fluid from passing under the tail to the leading edge of the next rotafoil. Instead of attaching the extensions to the tails themselves, they may be cast on a separate ring attached to the side disc. The axial discharge pipe may take the form of a diverging pipe I, Fig. 4, and a water seal 0 for the bearing is connected by a pipe O<1> to the discharge pipe in the usual manner. A pipe M connects the top of the suction inlet K to a space N from which air may be carried with water through the rotary member of the pump to the discharge outlet. The delivery pipe may be of uniform diameter externally; it then contains a tapered core to form an outlet of increasing cross-section. A modification suitable for a blower or hydraulic pump is shown in Fig. 8. The standard aerofoils is inverted and the resulting rotafoils are doubly flexed. The noses are tilted inwardly about 70 and the rotafoils occupy the full line positions D<1>, D2. The foils may be fitted with inwardly flexed tail extensions.
