Filed: 1957-07-05
Abstract: 815,691. Weighing apparatus. WAHL, E. A. July 5, 1957; No. 21368/57. Class 143 [Also in Group XXX] Apparatus for dispensing granular material at a predetermined volumetric rate comprises a hopper 15 and a dispensing tube 22 housing a screw 35 which is rotated at a predetermined constant speed and is vibrated simultaneously. The hopper is vibrated by an electromagnetic vibrator 23 and is adjustably supported separately from the rest of the apparatus by brackets 11 secured to the base 10. The tube 22 is mounted in a trough 25 and is cut away to form an inlet 41 for the material. The trough is supported only by the yoke 28 of an electromagnetic vibrator 29 which is secured to a relatively heavy base 33 supported by a sub-base 48. This sub-base is secured to the weighing platform 49 of the scale 12 by vibration absorbing mountings 50. A small mercuryswitch 53 is mounted on the scale beam 52 in such a position that when the scale is in the balanced, or over-balanced, positions, the switch contacts are open. These contacts are in series between the electromagnetic vibrator 23 and a source of current. The beam can move between stops 54, 55. When the trough 25 and the tube 22 are empty, the weight 51 is moved along the scale beam until the beam becomes horizontal. After this occurs the weight is moved towards the free end of the beam through a distance corresponding to one ounce on the scale. In this position' the beam will rest against the stop 54 and the switch 53 will close the circuit including the vibrator 23. Powder flows from the hopper and continues to do so until the added weight causes the beam to move towards the upper stop 55. As it does so the switch 53 breaks the circuit and the vibrator 23 becomes inactive. The motor 46 driving the screw 35 and the vibrator 29 is then set into operation by a manually-operated line switch.

Title: Improvements in electro-photoluminescent signal amplifiers
IPC: H04B10/00
Filed: 1957-07-10
Abstract: 827,555. Electrophotoluminescent amplifiers. GENERAL ELECTRIC CO. July 10, 1957 [July 12, 1956], No. 21854/57. Class 39(1). [Also in Groups XXXVI and XL(c)] In a signal translating or amplifying device a polarity - dependent field modulatable electrophotoluminescent member 3 emitting long wavelength radiation when irradiated with short wave-length radiation, is radiation-coupled with a photosensitive member 7 sensitive to the emission of member 3 and the member 7 is exposed only to the radiation emitted from member 3. A first pair of transparent conducting electrodes 4, 5 contact major surfaces of the electrophotoluminescent layer 3 and a second pair 8, 9 contact different surface portions of the layer 7 which is preferably photoconductive. A first filter 2 passes only radiation having a wavelength shorter than the fundamental absorption edge of the material of the layer 3 into the device and a second filter 6 passes only radiation having a wavelength longer than the same fundamental into the photoconductive layer. When the device is irradiated with such a shorter wavelength the luminescence of the layer 3 is stated to be modulatable by an alternating signal voltage applied across the terminals 10, 11 and the modulated amplified light output of the layer 3 is converted to a modulated signal output at the terminals 12, 13 of the photoconductive layer 7. Under suitable operating conditions the filters 2, 6 may be dispensed with. The photosensitive member 7 may be photoconductive, e.g. the sulphide, selenide or telluride of zinc cadmium or lead, or may be photovoltaic or may be a photomultiplier device. The electrophotoluminescent material may comprise phosphors of the zinc-cadmium sulphoselenide family activated with silver, gold, copper, arsenic and phosphorous together with a halide in the same percentage as the activator. Preferred proportions are stated in the specification, the activator concentrations generally being lower than for electroluminescent phosphors.

Title: Feeder for sleeve-enclosed edible cones
IPC: A23G7/00
Filed: 1975-05-21
Abstract: 1463274 Feeding cone-shaped articles one by one from a stack to a conveyer BIG DRUM Inc 21 May 1975 [3 June 1974] 21940/75 Headings B8A and B8S Cones in six stacks are fed into six respective apertures formed by cups 21 of an endless chain conveyer 21. As shown, the cones are ice cream cones C enclosed in a protective conical sleeve C<SP>1</SP>. The cones are released successively from the bottoms of each stack by an upper assembly 35 of horizontally movable jaws 38, a lower assembly 37 of jaws 58 (Fig. 5), and a downwardly and horizontally moving stripper assembly 36 having stripper fingers 75. Initially each stack is supported by the lower jaws 58. These are in their inward position (Fig. 8) supporting the stack by engaging the sides of the lowermost cone C. The jaws 58 are mounted on two jaw support bars 59, 59, which are slidable at each end on fixed rods 63, 63. Movement of the jaws is brought about by cam followers 72 which engage cam slots 71, 71 (Figs. 8, 10) in a vertically movable cam plate 55. The upper jaws 38 are mounted in a similar manner to the jaws 58, and have cam followers 52 at each end which slide in cam slots 51 also formed in the cam plate 55. The stripper fingers 75 are carried by two rods 73 which pass, at each end, through slide blocks 76 slidable in a horizontal slot 74 formed in the cam plate 55 at that end. Each end of each of the two rods 73 carries a cam follower 78 which operates in a respective cam slot 79 formed in cam plate 50. Thus on vertical downward movement of the cam plate 55 (starting from the position shown in Fig. 8), the jaws 58 are drawn apart, to release the lowermost cone C and the jaws 38 move inwards to engage under the rim of the next lowest cone. The stripper bars move downwardly under the action of the cam plate 55 to strip the lowermost cone, and due to upward movement of the cam 50, the stripper bars move inwardly, so as to follow the conical contour of the second lowest cone (this prevents damage to the outer liner C<SP>1</SP> of the latter). An assembly of plugs 102 is also moved downwardly as the cam plate 55 descends, so that a plug 102 is entered into each cone of the preceding row of cones on the conveyer. These plugs 102 (which later in the cycle of operation are raised again), have a reforming action on the mouths of the cones C.

[Classes 79 (ii) and 79 (v)] [Also in Group XXI] In a mining machine having a portable base adapted to travel over the floor of the mine, there is provided power operated propelling means, power operated steering means, and mechanism for controlling the supply of motive power from a source of motive power to both of said power operated means, said mechanism including a control device for controlling the supply of power to said steering means, a control device tor controlling the supply of power to said propelling means, and means whereby the operation of said steering control device for supplying power to said steering means will prevent the supply of motive power from said source to said propelling means. The axles of the front ground wheels are mounted in frames pivotally secured to the chassis, the setting of the frames being controlled by motors 11 and each wheel is driven by a motor 105 through a dual speed gear box and suitable shafting. The rear road wheels. 3 are used for steering, each being mounted in a carrier 191 that rotates about a vertical shaft 163 mounted at the outer ends of a transverse beam 160 that is pivotally secured to the chassis and adjustably locked relative to said chassis by a motor 12. Steering is done by a motor 168 acting through a linkage 165, 166 on each axle carrier. A motor 9 drives two liquid pumps, one a high capacity pump 214 and the other a low capacity pump 213. The pump 214 delivers into a manual valve from which flow may be directed back to the sump 215 or, depending on its setting, to motors 105 to drive them in one direction or the other. The low capacity pump 214 feeds a manually operated valve chest 10 which controls the various operating motors of the machine and in addition may be used to supply fluid to motors 105 in conjunction with pump 214, or when valve 221 is closed, may supply power to these motors alone. The supply from this low capacity pump is delivered into a chamber 251 of the multiple valve box 10 containing a plurality of two-way valves. From this chamber 251 the fluid is delivered into three supply passages 246, 256, and 254. The box is divided into two sections by a block 545 and liquid can be supplied to the right-hand side of the box, which also has three supply passages 246a, 256a, and 254a, through the passages 256 and 546 only as long as any valve on the left-hand side, other than valve 244, is not supplying liquid to the motor which it controls. Exhaust passages 258, 257 pass through each block to a chamber 252 connected to the reservoir. The valve 239 can direct fluid to the motors 105 by valve 248. The Specification as open to inspection under Sect. 91 comprises also an alternative valve chest assembly which forms part of the subject-matter of Specification 655,717, [Group XXI], which is referred to. This subject-matter does not appear in the Specification as accepted.
