Filed: 1937-07-07
Abstract: 491,341. Casting. METAL CARBIDES CORPORATION. July 7, 1937, No. 18905. Convention date, July 15, 1936. [Class 83 (i)] For controlling the cooling of molten metal introduced into a mould solid particles of metal are introduced thereinto during the pouring operation. In a process of continuous casting the molten metal and solid particles are simultaneously fed and may form a sheath between which the molten metal is fed. The solid particles may be in the form of a mesh. As shown in Fig. 1 powdered metal 20 from a hopper 21 is fed to the mould 33 simultaneously with the molten metal 10 from a crucible or ladle 11. In Fig. 3 is shown a continuous feed of solid particles 20 from hoppers 55 with molten material 10a therebetween, belts 50 forming conveyers. Arcuate magnets 53 cooperate with the belts to prevent the particles falling off the belts as the latter pass around the pulleys. The product 15 is suitable for further working. The Specification as open to inspection under Sect. 91 describes a modification in which metal in the form of a mesh is fed by belts either instead of or in addition to solid particles. The accumulation of solid metal on the sides and bottom of a pouring vessel is shown as also a cast metal product. This subject-matter does not appear in the Specification as accepted.

Title: Automatic cut-off nozzle for injection-moulding machines
Inventor: STUBBE FRIEDRICH
IPC: B29C45/23
Filed: 1967-04-26
Abstract: 1,148,828. Injection moulding machines. F. STUBBE. 26 April, 1967 [27 April, 1966], No. 19170/67. Heading B5A. An injection nozzle comprises two telescoping portions 1, 2 provided with a flow passage 3 for moulding material, one portion 1 having an injection orifice 5 and the other 2 being a tail portion connected to the injection cylinder (not shown), the flow passage 3 having a central portion 3a and two end chambers 3b, 3c of increased cross-section, and there being a core 4 floating freely in the passage. In the open position of the nozzle shown the head and tail portions 1 and 2 are displaced towards one another forming a flow passage for the material and when the nozzle is closed, Fig. 2 (not shown) with head and tail urged apart, sealing surfaces 6, 7 and 10, 11 on the nozzle and core engage to block the flow. The head and tail portions are normally urged apart by a spring 12, the pressure thereof being overcome by a predetermined pressure to open the nozzle. The portion 1 comprises a nozzle portion 1a with a guide portion 1b firmly screwed thereto on which an inner tail member 2a slides in sealing engagement, the part 2a and an outer part 2b being displaceable with respect to each other. In operation in the position shown with the nozzle la abutting a mould, the portion 1 is forced against the spring 12 until stop surfaces 19, 20 engage. The member 2a is now moved by the spring towards 2b until surfaces 21, 22 engage. Projections (13), (Fig. 2) on the core 4 engage the inner surface of nozzle la so that surfaces 6, 7 are disengaged, the material flowing from 3c-3b and through grooves 14 to the orifice 5. When the nozzle is moved from the mould the spring 12 urges parts 1, 2 apart and part la becomes separated from the projections (13). The core 4 is first displaced in the direction of flow under the pressure of the moulding material until surfaces 6, 7 bear together, and during further movement of the core 4 this moves member 2a until surfaces 21, 22 separate and surfaces 16, 17 engage to limit the travel of the core. Under the action of the spring 12 surface 7 bears on the surface 6 to block the flow while the spring also urges members 1 and 2a so far apart that the surfaces 10, 11 abut. During this stroke volumes 3a, 3c increase, so that material is sucked from the orifice 5 into the space 3b. The nozzle obviates explosion due to pressure increase because recesses 18 in core part 4c allow passage of material to bear on member 2a. If pressure increases above a certain value, Fig. 3 (not shown), the part 2a is moved against the spring pressure and surfaces 6, 7 are moved apart. Head portion 1 does not move, and material passes down recesses 18, passage 3 and through recesses 15 in the part 3b to the orifice 5 until the pressure decreases, when the spring returns the part 2a to close the recesses 18. Figs. 4-6 (not shown) disclose an embodiment in which the tail portion 2 comprises a single piece. A pneumatic or hydraulic device may replace the spring 12.

Title: Improvements in or relating to machines for repeating jacquard cards
IPC: D03C19/00
Filed: 1925-07-30
Abstract: 253,381. McMurdo, A., Morrell, L., and McMurdo, Ltd., J. July 30, 1925. Cards and the like, punching.-In a machine for repeating jacquard cards, the card to be punched and that to be repeated are moved step by step in longitudinal alignment, under vertically reciprocating punches and feelers, which are so interconnected that the punches only operate where the corresponding feelers indicate a hole to be repeated. A slide-block 12 mounted on a table 9 carries a pivoted perforated plate 15 under which the card to be repeated is placed and a clip 24 for the blanks. The slideblock is urged to the right by a weight 14 connected thereto by a cord 13, and is positioned by catches 67, 68 Fig. 4, on a lever 45, pivoted on the table and, engaging with pegs 70 on the block. The catches 67, 68 are respectively fixed and slidable against a spring 69 on the lever 45; when the lever is oscillated the catches alternately engage the pegs, so that the slide-clock is alternately held and allowed to shift one pegspace to the right. The main-shaft 25, Fig. 1, carries a hand-wheel and fast and loose pulleys 27. A crank 28 on the shaft 25 is linked to an arm 30 of a shaft 31, a second arm 37 on which is linked to a lever 34 pivoted at 35. A camshaft 47 is also chain-driven from the shaft 25. The arm 30 is pivoted to a rod 32, which is controlled by guides 33 and is spring-connected to the lever 34. The lever 34 is linked to sliderods 40 carrying the punching-head 22 and has pin-and-slot connection with the lever 45. A cam 48 on the shaft 47 oscillates a shaft 51, arms 53 on which are linked to the feeler-head 16<a>. When the feeler-head descends, the feelers 17 all pass through holes in the plate 15 and are then selected by the card beneath. Above each feeler is one arm of a bell-crank 19 pivoted in the feeler-head, the other arm being connected by a cord 20 to a spring-pressed slider 21 in the punching-head. Each feeler which does not pass through the card oscillates its bell-crank 19 to remove the slider 21 from above the corresponding punch 23 slidably .mounted in the head 22. When the punching-head descends only those punches which are held by the corresponding sliders, perforate the blank. As the slide-block 12 reaches the end of its traverse, a screw 64, Fig. 4, carried by an arm 63 thereon, contacts with and oscillates a lever 62 about its pivot on the table, so that a hook 60 pivoted' thereto raises a slide-bar 56 from a retaining- catch. The slide-bar 56 is thereupon shifted by a spring 58 so that a belt-fork 57, Fig. 1, carried' by the bar stops the machine. The belt-fork may be manually operated by a handle 55 on the bar 56.

Title: Improvements relating to actuating mechanism for epicyclic change-speed gearing
IPC: F16H61/02
Filed: 1934-07-02
Abstract: 440,375. Variable - speed gearing. DAIMLER CO., Ltd., POMEROY, L. H., and OLIVER, A. V., Daimler Works, Coventry. July 2, 1934, No. 19405. [Class 80 (ii)] [See also Group XXIX] Relates to servo mechanism for actuating a selected brake or clutch of an epicyclic variable-speed gear. The brake or clutch is operated by hydraulic pressure acting on a piston, not shown. Liquid such as oil is supplied from a reservoir 35, in which pressure is maintained by a pump driven by an electric motor from the car battery. To release a brake or clutch, a pedal acting through a crank 26 on a shaft 14<a> is arranged to open a relief valve 8. The shaft 14a carries a loose bell-crank 20 and pincerwise with respect to 20 is a bell-crank 13 mounted on a shaft 14 rotatable against a frictional drag device 19. The ends 12 of the bell-cranks are provided with contacts in the motor circuit and the lever 20 is provided with a stop 23 to limit relative movement of the levers in the contact-opening direction. A spring-pressed ram 11 exposed to the oil pressure has a head 16, which on a fall of pressure engages a projection 15 on the lever 13 and thus rotates it so that the contacts engage and the pressure is boosted up again. If the pressure rises too high, a shoulder, not shown, on the ram 11 engages the projection 15 and rocks the lever 13 so as to break the contact. A rocking lever 24 is mounted on a projection of the shaft 14<a>. When the operating pedal is completely depressed, the lever 24 opens a subsidiary ball-valve 30 and finally the main relief valve 8, and the pressure in the system is relieved. A spring (not shown), then moves the actuating piston to disengage the operative brake or clutch. The ram 11 is unable to start the pump motor again until the pedal is released. If the pedal is only partly depressed, the ram 11 can start the pump and re-close the valve 8 when the pressure falls and the system comes to rest with a certain reduced pressure in the servo cylinder, the valve 8 being opened if the pressure rises beyond this amount.

A system easily installed in an existing cinema or other auditorium and enabling the individual members of the audience to express their preference, by means of a visible indication, as to which one of two alternatives of the plot of the film shall be followed, comprises on an arm rest 11 of each seat a box 13 containing a radio transmitter. Each box 13 has a red button 17 and a green button 19, the person sitting in that seat expressing his choice by pressing the appropriate button. Each box 13 contains a radio-frequency oscillator 21 and an audiofrequency oscillator 23 having a frequency of 10 Hz. The oscillators 21 all operate at different frequencies to distinguish each seat from the others. If the red button 17 is pressed it energizes the oscillator 21 and applies an R.F. carrier of a particular frequency to the antenna 31. If the green button is pressed the oscillator 23 is also energized so that the R.F. carrier is modulated by the A.F. signal. The signals from all the boxes 13 are received by a common loop antenna 35 at the front of the auditorium and these signals are applied through a filter 39 and preamplifier 41 to a number of receivers 43 corresponding to the number of boxes 13, each receiver being tuned to a corresponding box. Each receiver 43 has a two-position output device 45 so that a signal is provided on a particular one of two output lines in depence upon whether the received R.F. signal is modulated or unmodulated. The output lines from each receiver are connected to a corresponding pair of red and green lamps 51, 53 and to a common pair of summation devices 47, 49. Each pair of lamps 51, 53 is on a number panel 54, visible to the audience, and indicating one of the seats. Thus each red or green button pressed causes a corresponding red or green lamp to light and the totals of the red and green lamps illuminated are displayed numerically, respectively, by the devices 49, 47. According to the "red" and "green" voting, the corresponding one of two film projectors is used to follow the chosen sequence of the film story. In a modification (Figs. 7, 8, not shown) the number of R.F. channels required is reduced by a factor of ten by arranging the seats into groups of ten and allocating a particular R.F. to each group. Only a single transmitter box is provided for each group and this box contains twenty A.F. oscillators operating at different frequencies. Each seat has a pair of red and green buttons wired to the common transmitter box and the receivers include audio stages and incorporate output devices which respond only to the R.F. carrier as modulated with the appropriate audio frequency.
