Title: Matrix malfeeding detection system for line casting machines
Inventor: GREENE HARRY R
IPC: B41B11/18
Filed: 1959-04-01
Abstract: 877,268. Photo-electric malfunctioning detectors. KNIGHT NEWSPAPERS Inc. April 1, 1959, No. 10993/59. Class 40(3) [Also in Group XVI] A matrix malfeeding detection system for halting a typographical line-casting machine upon failure to feed a matrix from a magazine into a matrix channel, feeding of an unwanted matrix, or jamming of a matrix at the magazine outlet, comprises a photo-electric cell and a light source disposed so that the light beam is intercepted by matrices leaving the magazine, a first stepping relay operated by a switch actuated by each character-selecting action of the machine, a second stepping relay operated on interruption of the light beam, the relays having movable contact assemblies electrically connected in open-circuit relationship but relatively movable into closedcircuit relationship during malfeeding, an electrically operated machine-halting device, and normally-inoperative locking relay means actuated when the step relays come into closed-circuit relationship to operate the halting device. The automatic control unit and the casting machine are stopped when a coil 9 is energized as a result of energization of either relay 28 or relay 30. Interruption of the light beam to the cell 20 deenergizes coil 88 and energizes the coil 94 of stepping relay 26, rotary contact blades 136, 138 of which move one step. The stepping relay 24 coil 104 is energized when the character-selectionresponsive switch 72 is closed, and rotary contact blades 132, 134 move one step. In normal operation, no circuit is completed through the blades, but if the relay 26 drops behind owing to lack of a matrix or jamming thereof, or moves ahead owing to feed of unwanted matrices, after two steps a circuit is completed to either relay 28 or relay 30. Coloured lights 56, 58 indicate which if either relay 28, 30 is energized. A pushbutton simultaneously actuates switch 42 to step the relay 26 repeatedly through contacts 98, 100 opened when the coil 94 is energized, a switch 40 similarly to step the relay 24 and break a holding circuit to either actuated relay 28 or 30, and a switch 44 to keep the solenoid 9 energized while the relays 24, 26 are being restored to their initial positions.

Abstract: 1424613 Laminating foraminous layers on a surface PLASTICS DESIGN & ENG Ltd 7 June 1974 [7 March 1973] 11026/73 Heading B5N A surface is coated with layers of foraminous material by attaching fixing devices to the surface, mounting at least one layer thereon to overlay the surface, applying one or more further layers at least the outermost of which covers the fixing devices, and impregnating all the layers, either before or after placing them in position, to bond them to one another. Metal, wood and concrete surfaces may be coated. In one embodiment, a tank is lined with chopped strand glass fibre mat impregnated with polyester resin. Studs are welded at intervals to the tank surface and a first layer of mats is loosely held in place by spring washers on the studs. The studs are then cut to a desired length and the mats are impregnated throughout. After peening to tighten the washers, a second layer of mats is applied over the first layer, and is similarly impregnated. Preferably the second layer covers the peened studs, but, if not, a narrow mat strip may be applied for this purpose.

Abstract: 1346251 Air filter UNITED FILTRATION CORP 23 April 1971 [27 April 1970] 11044/71 Heading BIT A filter for removal of dust from air for the air intake side of an I.C. engine comprises a cylindrical housing 10 formed of two halves 12, 14 and having a tangential inlet 30 and an axial outlet 35, the air passing from the inlet to the outlet via cylindrical filter element 24 comprising, in series, an outer element 26 and an inner pleated paper element 28. A helical depression 54 is formed at the inlet end of the housing so that incoming air is directed away from the inlet with helical motion towards the opposite end of the housing with consequent centrifugal separation of part of the dust before the filtration. The filter element is held in place by bolt 60 and centre bale 38. The outlet end of the filter element has two annular plastics seals 70, 82 (Fig. 4), the inner one of which 70 is shaped to aid correct seating of the filter element in the housing. The filter element is changed via open end 20 of the housing which is sealed in use by a cover 40 which is removably attached to the housing end by a bayonet-type connection and which carries an overcentre bale mechanism 98 which is operable to simultaneously supply an axial thrust to the filter element to push the seals. 70, 82 tight against the end 22 of the housing and to hold the cover 40 tight on end 20 of the housing. An outlet 36 is provided for separated dust.

Title: Improved control system for fluid servo-mechanisms

Filed: 1950-05-05
Abstract: 677,668. Variable-pitch propellers. GENERAL MOTORS CORPORATION. May 5, 1950 [May 7, 1949], No. 11117/50. Class 114. [Also in Group XXIX] The blades 22 of a variable-pitch propeller are interconnected by co-ordinating gearing 144, 146 and adjusted by servo-pistons 14 having external helical splines 140 coacting with the blades and internal helical splines coacting with similarly splined, fixed, bosses 142 to cause rotary adjustment of the blades upon axial movement of the pistons. A housing 152, which rotates with the propeller shaft 26, carries a hydraulic pump 42 which feeds the servo control valve 36 and is geared to a fixed wheel 174. The valve 36 is actuated by solenoids 58, 60 fed from an electric supply source 64 through brushes 200, 202, 204, a continuously rotating contact drum 74, and a pick-up contact 104. The drum 74 has a zig-zag insulating portion, 84 so arranged that when the pick-up contact 104 makes contact with the mid-portion of the drum, opposite deflections of equal duration are alternately imparted to the control valve 36 by the solenoids but when the pick-up contact is moved in response to a change in speed of the propeller shaft 26, as detected by a governor 122, opposite deflections of duration are imparted to the control valve to cause adjustment of the servo-pistons 14. The control point is adjusted by a hand lever 194 which moves the drum 74 axially. The lever 194 is also connected, through a link 192, gear ring 186, threaded spindles 178, a grooved ring 180 having threaded engagement with the spindles 178, and a shoe 182 coacting with the grooved ring, to the datum varying means 198 of a stand-by governor 158. This governor is normally inoperative, being less sensitive than the governing system embodying the valve 36, but is effective to cause feathering, unfeathering and pitch-reversal upon appropriate adjustment of the hand lever 194. The motive fluid for feathering and unfeathering is derived from an accumulator 168 under the control of a valve 166 which is tripped by a shoe 184 during movement of the grooved ring 180.
