Filed: 1928-07-11
Abstract: 315,566. Wellman Smith Owen Engineering Corporation, Ltd., (Wellman Seaver Morgan Co.). July 11, 1928. Charging.-In apparatus for feeding fuel to gas producers of the kind comprising superposed hoppers 11, 12 closed by alternately operated counterweighted bells 20, 21, the latter are actuated by a cam with which is combined a second cam adapted to move a separate weight simultaneously with but in the opposite direction to the bell weights 35, 36, this arrangement assisting the driving mechanism to raise the weights and preventing over-running during their descent. The arms 22, 25 carrying the bells 20, 21 are secured to squared portions of shafts 26, 27 by hubs which are sector-shaped, as shown in Fig. 2, to prevent passage of fuel through the openings 31, 32. A shaft 59, which is intermittently rotated from a main driving-member 43, 44 through links 58, 55, 67, and pawl and ratchet mechanism 61, 66, has rigidly secured thereon a sleeve 68 which is formed with two cam surfaces 69, 70 of the form shown in Fig. 4. The former is adapted to engage alternately with followers 74, 85 mounted on arms 84 carrying eye-bolts 76 which engage over pins 78 on crank arms 79 formed integral with the counterweights 35, 36. The cam 70 co-operates with a follower 82 mounted on an arm 81 which is connected, in the same way as the arms 84, to a weight 80 loosely mounted on the shaft 26. The shaft 59 is operated by the inward stroke of the driving- member 43, 44, the outward stroke of the latter being utilized to actuate, through arm 53, 54, yoke 51, and link 48, pawl and ratchet gear 45, 47 which intermittently rotates a pooketted drum 39 to deliver fuel from the inlet 42 to the upper hopper 11. The link 48 is pivoted at its lower end to a nut 49 on a screw 50 which latter is mounted in the yoke 51 and carries a handwheel 52 by which the rotation imparted to the drum 39 may be adjusted. To prevent injury to the mechanism should the feeder or bells jam, the driving member 43, 44 and the arm 53, 54 are each formed in two parts connected by a shear pin 185, an adjustable stop 87, locked in position by a wing nut, being provided to take up any looseness due to a badly fitting shear pin. The bell valves 20, 21 co-operate with seatings 16, 17 formed on annular discs 14, 15 which are disposed between the, parts 11, 12, 13 and may be removed by separating these parts by means of set-screws 19, Fig. 1.

Filed: 1918-12-05
Abstract: 135,952. Forrester, H. J. C., (Michle Printing Press & Manufacturing Co.). Dec. 5, 1918. Rotary machines; tripping and like arrangements.-A rotary printing-press, adapted to be used as a single-colour, two-colour, or perfecting press, is provided with two plate surfaces cooperating with two impression surfaces and adapted to be moved individually, as desired, into an inoperative position, so that one surface may be plated and prepared for printing the new job while single-colour work is being printed from the other surface. The press shown in Figs. 1 and 3 comprises an impression cylinder 13 with two impression surfaces 26, 27 coacting respectively with plates 30, 31 on plate cylinders 14, 15. The cylinders 14, 15 are mounted in sliding bearings 17 operable by toggles 19 and hand-levers 20 so that either cylinder may be moved into an inoperative position for replating while sheets are being printed in a single colour by the other cylinder. A transfer cylinder 33 coacts with the cylinder 13 and is mounted to slide in an arcuate guide 23 by hand-operated screw and bevel gears 24, so that it may be moved into contact with the cylinder 15 while remaining in contact with cylinder 13. For two-colour work, the cylinders are arranged as shown. The sheet is taken from the feed-board 11 by the grippers 28 of the impression surface 26 and printed by the cylinder 14. It is then taken by the cylinder 33 and transferred to the grippers 29 of the surface 27 to receive the second impression from the cylinder 15. The sheet is delivered by a delivery apparatus 12. For single-colour work, one of the cylinders 14, 15 is moved out of contact with the cylinder 13, the passage of the sheet being the same as before. For perfecting, the cylinder 33 is moved into contact with the cylinder 15, which is moved out of contact with the impression cylinder 13. By this arrangement, the cylinder 33 acts' as an impression cylinder while the sheet is being perfected by the cylinder 15. Fig. 6 shows diagrammatically a combination of two presses such as described above, with a transfer cylinder between them. With such a press, sheets may be printed in four colours on one side, or three colours on one side and one colour on the other, or two colours on each side.

Title: Improvements in peak-reading circuit
IPC: G01R19/04
Filed: 1959-06-12
Abstract: 866,232. Peak voltage measurements. GENERAL ELECTRIC CO. June 12, 1959 [June 16, 1958], No. 20185/59. Class 37. In a peak voltage reading device, a capacitor 10 develops, through rectifier 9, a voltage E10 proportional to the input peak-to-peak voltage at terminals 1<SP>1</SP>, 2; and a decrease in this peak voltage causes a control voltage E14, across capacitor 14, and which is greater than E<SP>1</SP>0 for an increasing or constant peak voltage, to decrease, thereby reducing the bias on a discharge path for capacitor 10, constituted by rectifier 17 and resistance 15, and enabling E10 to follow the decrease in the peak voltage. The input voltage is applied across resistors 5 and 6, the voltages E10 and E14 being derived respectively from the voltages across resistor 6 and from a tapping on resistor 5. Discharge of capacitor 10 through rectifier 17 and resistance 15 is prevented, by the biasing effect of E14, unless reduction in the input peak voltage occurs, in which event voltage E14 is reduced thereby enabling E10 to decrease in accordance with the new peak voltage. In a second embodiment, Fig. 4 (not shown), a measure of the zero-to-peak rather than the peak-to-peak input voltage is obtained; and impedance matching cathode follower circuits are provided at the input and output of the device.

Title: Apparatus for continuous chilling of fowl carcasses
Inventor: SHARP ALLEN WILEY
IPC: A23B4/06
Filed: 1961-06-05
Abstract: 994,179. Cooling poultry. BARKER AUTOMATION Inc. June 5, 1961, No. 20255/61. Heading F4H. An apparatus for a continuous process of chilling eviscerated fowls in an agitated body of water, comprises an open topped elongated water tank, mounted for a transverse rocking movement on a support. Two elongated tanks 11 and 12 are arranged end to end, Fig. 1, one containing cool tap water for pre-cooling the fowls, and the other water and ice for the final chilling of the fowls to a temperature not exceeding 36‹ F. Each tank is formed from a number of tank sections 14 bolted together at adjacent end flanges 20. One flange for each section has an arcuate bearing surface 25 which runs on rollers 27, Fig. 4. A reinforcing tube 32, Fig. 5, is butt welded between the flanges of each section, and welded to the underside of the tube 32 of one of the sections of each tank is a pair of lugs 34, Fig. 11. A connecting rod 36 driven by a crank arm assembly 44 mounted on the support 10, is connected to the lugs 34 and provides the rocking movement of the tank. If the tanks were semicircular in section, no agitation would be imparted to the water. The tank is therefore built so that the central portion of the bottom wall extends above any other portion of the bottom wall. As shown in Fig. 5, the tank is made from a plurality of flat, longitudinal extending sections 16 and 18, giving a correct cross-section for agitation. In another embodiment (not illustrated), the bottom wall has an inner surface of convex arcuate form, and the side walls of concave arcuate form. The extreme left end of each tank is provided with a further tank section 50 containing a conveyer 54 mounted on arms 64 to bring it into and out of operation, as shown by the dotted lines of Fig. 10. Water in each tank is pumped up an upright duct 80 by an impeller 81 from the bottom of the tank section 50 and flows along an open flume 88. With tank 11, it then flows through a pair of discharge conduits 90 back into the right hand end, causing a flow of water along the tank. With tank 12, a similar pair of conduits 94 are provided together with an intermediate trough 92, shown in Fig. 8. A certain amount of water is allowed to flow into the tank 11 from the trough controlled by a gate 95. Each tank is provided with a cool water tap 72. Fowls are introduced into the right hand end of the tank 11 and subjected to a free unrestricted turning and displacement action and simultaneously moved to the opposite end of the tank by the flow of water. They are then transported by the conveyer 52 to the tank 12, where the same action takes place.

Abstract: 1505190 Field-effect transistor switching circuits RCA CORPORATION 14 May 1975 [5 June 1974] 20327/75 Heading H3T [Also in Division H2] A voltage multiplying circuit comprises eight complementary enhancement-mode field-effect transistors connected substantially as shown. As described, transistors P71, N71 are made alternately conductive by a clock frequency square wave at Q, giving an inverse clock Q which drives transistors P74, N74 in opposition. When Q becomes + V, N71 and P74 turn on so that the right hand side C72 swings from O to V. Assuming Z was initially at + V, it must now change to + 2V, this turns on N72, clamping plate Y of C71 to +V. When Q becomes O, N71 is turned off and C71 on causing plate X of C71 to rise towards + V, thus turning off P74 and turning on N74. This changes the potential at W from + V to O and that at Z from +2V to +V. Signals at E and D are available swinging from +V to +2V. When power is initially supplied to the circuit, plates Z and/or Y are charged initially by the forward biased diodes formed by the diffused regions of transistors N72, N73. P75 and P76 operate on these waveforms to provide a D.C. supply of 2V.

Abstract: 478,881. Sewing-machines. ROBERT, R. C. July 22, 1936, No. 20336. [Class 112] A compact feeding device has a dog operated by a triangular-shaped eccentric and a forked lever. When the shaft 1 rotates, two non- consecutive quarters of a revolution of the eccentric 2 actuate the forked lever 13 which gives a rise-and-fall movement to the pin 15 on which is mounted the feed bar 6 carrying the dog 16. The feed bar is guided by vertical guides 6<1> on the rod 3. During the other two quarters of the revolution of the eccentric 2, alternating with the quarters producing the rise-and-fall movements, the eccentric operates the rod 3 by working in a square hole 4, causing the rod to swing about the pivot 5 on the link 8 swinging on the pivot 7 and so impart the feed movement to the dog 16. The stitch length is regulated or the feed reversed by loosening the screw 11 and swing- ing the arm- 10 to the right or left. This turns the shaft 9 axially and alters the relation between the pivots 5 and 7. The device may be put out of action by moving the eccentric axially out of the square hole 4.
