Title: Improvements in apparatus for securing bale and like ties
IPC: B65B13/34
Filed: 1934-03-14
Abstract: 435,391. Strapping packages &c. SIGNODE STEEL STRAPPING CO., 2600, North Western Avenue, Chicago, U.S.A. March 14, 1934, Nos. 8080 and 8081. Convention dates, March 14, 1933 and Sept. 14, 1933. [Class 45] [See also Group XXII] Relates to a package-strapping apparatus wherein the straining of the iron hoop and the sealing and cutting thereof are all effected by a single lever. This lever is formed in two interpivoted parts 3, 4, Fig. 3, which are latched together by spring-pressed plungers for the straining operation-the lever being oscillated as a whole for this purpose about the shaft 2 of the serrated straining disc 8, and the parts are unlatched for the sealing and cutting operations, the part 4 that performs these operations being swung about a cam-shaft 19 for these purposes. The serrated straining disc is eccentrically mounted on the shaft 2 and is lowered into contact with the iron hoop by manually rotating the shaft, the disc being subsequently rotated for straining the hoop by the engagement of a pawl 6 carried by the lever 3 with a ratchet wheel 7, another pawl 6<1> preventing reverse movement of the disc. The sealing and cutting mechanisms 15, 29 are carried by and move with the lever 3 during the straining operation after which the parts 3, 4 are unlatched by swinging the lever as a whole into the fully horizontal position shown and then raising, against its spring 55, a lever 53 pivoted to the part 4. This permits a spring 60 to rotate a lever 56 counterclockwise so that a lug 58 carried thereby engages under a stationary lug 59. The part 4 may now be rotated counterclockwise about the shaft 19 to the position shown in Fig. 8, the part 3 and the sealing and cutting mechanisms now remaining stationary due to their being locked at 58, 59. The lever 4 is now rotated clockwise so that the projecting end 54 of the lever 53 engages the heel 20<1> of a cam 20 to rotate the latter which engages between the arms 21 of the sealing blocks 15, 15<1>, Fig. 7, normally held apart by a spring 44 and forced together by the cam to coact with the stationary jaws 45. The blocks 15, 15<1> are notched at the parts where they coact with the jaws 45. The cam subsequently acts on a lever 29<1>, Fig. 3, to depress a plunger against its spring 26 to operate the cutter blade 29 which is secured to the plunger. A plate 41 separates the two laps of the hoop and prevents the severing of the lower lap. In the form shown in Fig. 15, the cam for operating the sealing jaws is provided with three bosses 20<11> each having a heel 20<1> and narrowing from both sides to the points 20<111>. These cams act on rollers 21<11> on the arms of the sealing blocks 15, 15<1>.
Patent GB-639258-A (GB)
Title: A new or improved method of drying salt fish
IPC: A23B4/03
Filed: 1947-03-25
Abstract: A process of drying fish comprises spreading a single layer of fish upon each of a plurality of open stackable frames (see Group XIII) adapted to support the layer while permitting of free circulation of air to its under surface, and alternately spacing the trays apart from one another while exposed at the same time to a drying atmosphere, and stacking one on top of the other in superposed relationship with the layers of fish pressed tightly between the adjacent frames, the steps of alternately spacing and stacking the frames being continued without removing the fish from the frames until the desired degree of drying of the fish has been effected. The exposure of the fish to a drying atmosphere may be effected by placing the frames successively on a moving conveyer adapted to permit of free circulation of the air to the undersurface of the frames, or by retaining the trays in stacked relationship but separated from each other by blocks of wood. Instead of the natural drying effect of the sun and wind being used warm air may be blown through a shed in which the trays are exposed.

Abstract: 912,617. Valve amplifying circuits. COMMISSARIAT A L'ENERGIE ATOMIQUE. March 10, 1959 [March 10, 1958], No. 8233/59. Class 40 (6). [Also in Groups XXXVI and XL (b)] In a photo-electric servo-system (see Group XL (b)) a frequency selective amplifier comprises two long-tailed pair stages, of which only one input is used, followed by two parallel pentodes as an output stage, the anodes of which supply a frequency dependent negative feed-back to the grid of the first long-tailed pair. The input from the photo-cell pre-amplifier 33 is applied to one grid 36 of double triode 37, the other grid being kept at constant potential, to minimise negative feedback due to the resistor 40. The output from the second, similar, stage is applied to the grids of pentode drivers 42, 43, in the cathode circuit of which is a solenoid 11 acting to keep the light falling on the photo-cell 13 constant. The anode of pentode 42 is connected through a variable low-pass T-section filter 45 to grid 36 to provide negative feed-back. Specification 727,171 is referred to.

Filed: 1964-02-28
Abstract: 986,656. Hydraulic control systems for lift truck attachments. YALE & TOWNE Inc. Feb. 28, 1964 [March 14, 1963], No. 8342/64. Drawings to Specification. Heading B8H. An electro-hydraulic control system for a rotating, side-shifting clamp attachment on the lifting carriage of a lift truck comprises a pair of hydraulic lines extending from a source of fluid pressure and through a main directional control valve on the truck body, Fig. 3 (not shown), to two solenoid valves on the lifting carriage controlling the hydraulic rams for rotating, side-shifting and operating the clamp arms of the attachment. The arrangement is such that on moving a hand lever controlling the main control valve fluid passes through the solenoid valves to the clamp rams which are extended or retracted according to the direction of movement of the hand lever. The solenoid valves are actuated by push-buttons on the hand lever which is connected to a switch whereby operation of the push-buttons is rendered ineffective unless the hand lever is in its neutral position so that rotation or side shift of the attachment cannot be effected during operation of the clamp. On pressing one of the push-buttons with the handle in the neutral position, a circuit to the appropriate solenoid valve is set up and on subsequently moving the handle in the desired direction the switch actuated thereby sets up a holding circuit and pressing of the other push-button is rendered ineffective. In a second embodiment, Fig. 4 (not shown), a pair of solenoid valves is provided to control the rams for effecting the three operations, each pair being actuated by a push-button on the hand lever, the arrangement being such that during one of the three operations, the push-buttons corresponding to the other operations are rendered ineffective.

Title: Frequency modulation systems
IPC: H03D3/00
Filed: 1943-05-26
Abstract: 564,041. Telephone transmission. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. May 26, 1943, No. 8432. Convention date, May 27, 1942. [Class 40 (iv)] [Also in Group XL] In a frequency modulation system the frequency deviation is kept within comparatively narrow limits by compressing the volume of the signal at the transmitter prior to modulation and correspondingly expanding the volume at the receiver after demodulation. A pilot signal indicating the degree of compression and expansion comprises a variable supersonic frequency sent as a frequency modulation of the carrier. The transmitter, Fig. 1, may comprise a microphone 1, amplifier 2, thermionic variable reactance 3, carrier wave source 4 and aerial 5. The amplifier 2 feeds a rectifier 9 which comes into action at a determined input voltage and produces an " envelope " voltage across its load resistance 10, which voltage is applied to the amplifier 2 to reduce its amplification as the volume of signal increases. The voltage across resistance 10 is also applied to a thermionic reactance 7 so as to vary a supersonic frequency generated at 6 and applied to the reactance 3 to frequency-modulate the carrier wave. At the receiver, Fig. 4, the amplifier 13, which may include a superheterodyne stage, feeds a detector 14 from which the detected signal passes through amplifiers 15, 16 to the sound reproducer. The supersonic pilot signal is selected by a filter 17 and its frequency variations are detected by a resonant transformer 21 and rectifier 18, the resulting voltages across the resistance 19 being applied to the amplifier 16 to expand the volume in accordance with the compression effected at the transmitter. On account of the reduced frequency deviation of the carrier, the amplifier 13 may pass a comparatively narrow band.

Abstract: 633,868. Sewage disintegrator. SULZER FRERES SOC. ANON. March 28, 1947, No. 8477. Convention date, March 30, 1946. [Class 28(ii)] [Also in Group II] A disintegrator for sewage, which acts like a mincer, has an adjustment whereby the rotary cross bladed knife 5 can be adjusted axially towards or from the cooperating grating 7 without stopping its rotation. The shaft 4 carrying the knife 5 at its lower end is supported by a thrust bearing 13 in a casing 16 which can be moved up or down by rotating a handwheel 22 which screws the flange 20 of the casing 16 up or down to effect the adjustment. The adjustment is then held in clamped position by screwing down the studs 23. In practice, to clear the blades of adhering matter they are first moved away from the co-operating fixed grating 7 and clean water may be flushed through, after which they are adjusted to within about 1 millimetre. A scale 35 indicates the degree of adjustment. A distance piece may be inserted between the grating 7 and the knife 4. The adjustment could also be made by suitable levers or eccentrics. A distance piece could be inserted to adjust the grating. Another non-rotating blade 27 cooperates with the lower edges of the blades of the knife 5 to effect further cutting. This blade is adjustably slidable in a guide 38. Channels 32, 33 and 34 can also provide flushing water under pressure between the knife 4 and the grating 7. The shaft 4 is coupled at 26 to a power drive, e.g., an electric motor.
