Title: Improvements in or relating to means for forming cellular structures from a pile of webs joined together by spaced glue lines
Inventor: STEELE ROGER C
IPC: B31D3/02
Filed: 1954-03-01
Abstract: 784,135. Laminates. HEXCEL PRODUCTS, Inc., [formerly CALIFORNIA REINFORCED PLASTICS CO.]. March 1, 1954, No. 5959/54. Class 140. In making a cellular structure by expanding a pile of webs or strips joined to each other along lines which are parallel and staggered from strip to strip, the necessary pulling force is applied to the pile at spaced points along the pile through means capable of relative movement so as to allow them to move inwards as the pile contracts in width concurrently with its expansion in length. As shown, a strip 16, Fig. 5, of cloth having evenly-spaced, closed loops 17, the base ends of which are joined together by adhesive, stitching, or staples 18, is secured to the end web 29 of a pile A of honeycomb-forming webs by means of a tape 28 coated on both sides with pressure-sensitive adhesive. Each loop carries a tug-pin 19, and the ends of the tug-pin projecting from the loop are slidably mounted on trackways 26 and 27, Fig. 8, hingedly supported on a frame 22 by pivoted arms 23 and 24. A similar arrangement of looped tape, tug-pins, and frame is secured to the other end web of the pile. When the frames are pulled apart to expand the honeycomb, the end webs purse inwardly and the tug-pins carried by the loops slide inwardly on tracks 26 and 27. The tracks may be slightly bowed towards the centre of the pile.

Title: Radio time interval measuring system
IPC: G01S13/78
Filed: 1945-03-09
Abstract: 593,151. Radiolocation. STANDARD TELEPHONES & CABLES, Ltd. March 9, 1945, No. 6007.' Convention date, March 13, 1944. [Class 40 (v)] [Also in Group XXXVI] The time interval between the pulses of pairs of pulses forming a pulse train is measured by producing a rectangular impulse of duration equal to the time interval, and a rectangular impulse of substantially constant duration greater than the longest interval between the pulses of the pairs and measuring the ratio between the energy content of the two rectangular impulses. In the radio distance measuring system of Fig. 1, a pulse generator 40 controls the transmitter 42, and pulses relayed from distant repeaters are picked up by receiver 54 which is coupled to the pulse generator by a sensitivity control means 52. The transmitter control pulses are fed to a multivibrator 44, followed by a limiter 46, which produces rectangular impulses of a constant duration corresponding to the maximum distance to be measured. These impulses are fed to one coil 48 of a cross-coil ratiometer 50. The pairs of pulses from the output of receiver 54, corresponding to the direct received transmitter pulse and the repeated pulse are supplied to operate a trigger circuit 56 which produces a rectangular pulse equal in duration to the pulse spacing. These pulses are fed over limiter 58 to the other coil 60 of meter 50, the scale of which may be calibrated in terms of the distance of the repeating object. The system may be tuned to operate with different pulse repetition rates for the purpose of selectively energizing and identifying different repeater stations. The Specification as open to inspection under Sect. 91 comprises also a radio range-measuring system, Fig. 1 (Cancelled), consisting of a pulse generator 10, transmitter 12, receiver 20 and sensitivity control means 18 which co-operates with distant repeaters such as 14, 16. The pairs of pulses 20a, 20b from the receiver control a trigger circuit 24 producing the rectangular pulses 24A of width proportional to the range of the repeater. These rectangular pulses are converted at 26 to saw-tooth waves 26A of constant scope and thus of amplitude proportional to range, the peak amplitude being indicated by a voltmeter circuit comprising condenser 38, diode 34 and meter 36. This subjectmatter does not appear in the Specification as accepted.

Title: Improvements in or relating to the determination of the hardness of materials
IPC: G01N3/42
Filed: 1950-03-10
Abstract: 708,171. Testing hardness of materials. TSCHIRF, L., and MITSCHIE, R. March 10, 1950 [March 10, 1949], No. 6029/50. Class 106 (2) A method of determining the hardness of a material consists in employing a hardnesstesting apparatus in which a penetrating body is pre-loaded and, after contact with the test piece is given a main load and which, during the application of said main load (or during its continuance after application) is subjected to controlled vibrations to an extent where further vibrations do not affect the indicated hardness value the hardness value being read after removal of the main load and before removal of the pre-set load. The indentor a, Fig. 1, is housed in a bore of a pressure die b in which a spiral spring c exerts a force of 10 kg. (" minor " load). The " major " load is produced by 'a set of springs F fitted in a bush d in a casing k and is transmitted via a spring dish T, a ball-bearing f, and a collar b<SP>1</SP> to the die b. The tops of the springs F abut a die b. The tops of the springs F abut a screwed plate P by which their tension may be adjusted. The dish T has a ramp which cooperates with a ramp on a ring h which can be rotated by oscillation of a lever H to allow application of the " major " load to the test piece. The depth of penetration is indicated by a dial indicator n. An indentor protecting cap g is pressed outwards by a spring j in a ring i. Surrounding the casing k is a ring q, Fig. 4, which is rotated during the test to compress a spring t the subsequent expansion of which causes a pair of pawls N carried by a lever B to ride over the teeth of a fixed ratchet s so that a pair of clappers r strike the casing k and produce vibrations of the appliance and test piece.

Title: Improvements in microwave circuits
Inventor: MULLETT LESLIE BADEN
IPC: H01P5/12
Filed: 1949-03-04
Abstract: 667,290. Wave-guides. NATIONAL RESEARCH DEVELOPMENT CORPORATION. March 23, 1950 [March 4, 1949], No. 6035/49. Class 40 (viii). A microwave circuit arrangement having a number of input and output connections between certain of which power can pass without affecting other connections comprises a number of rectangular wave-guide sections supporting H 01  modes connected at spaced points to a section of circular guide supporting a H 11  mode. In the first construction a fourarm bridge arrangement is shown. Power is fed from two sources into input guides 1 and 2 respectively, the latter being arranged at right angles. By the transformer action of their junctions with circular guide 5, each gives rise to a H 11  wave in guide 5 polarized at right angles to the axis of its corresponding rectangular guide. Two output guides 3 and 4 positioned at right angles are provided and, by a suitable choice of the angle # between the two pairs of guides, the resultant wave in guide 5 is coupled to one output guide and does not affect the other. An application to an attenuator is shown in Fig. 2. Power passes from an input guide 11 to output guides 17 and 18 through two circular guides joined by a rotatable rectangular guide 14. This latter varies the plane of polarization of the wave in guide 16 and thus varies the ratio in which the power is divided between guides 17 and 18. One of these is connected to a dummy load and the other provides a variable output. Specification 654,906 is referred to.

Abstract: 973,704. Reciprocating pumps. AUTO RESEARCH CORPORATION. Feb. 17, 1961 [Feb. 19, 1960], No. 6036/61. Heading F1A. A reciprocating pump for a lubrication system with branched distribution piping has an adjustable stroke hydraulic piston driving the pump piston through reduction gearing. The pump unit is mounted in a reservoir A provided with a sight glass G. A transverse shaft E is actuated by a lever H and a hydraulic cylinder arrangement J having a slidable plate 60 to adjust the stroke of the piston L. Ratchet wheels 89, 108 allow unidirectional rotation of the shaft E which rotates a shaft 136 through bevel gears. A cam-shaft 153 is rotated by worm gearing 150, 152 and the cam follower 160 is mounted between side plates 162 of a lever T pivoted about a bolt 163. The plates 162 lift the pump piston P to draw in lubricant through a filter Q and a spring 193 forces the piston down to pass the lubricant into outlet pipes R, Y, the latter lubricating the shaft E and the gears 133, 135. Rotation of the knurled member 170 alters the fulcrum setting of the lever T to vary the stroke of the pump piston (see Fig. 5). Manual operation of the pump is provided by lifting a knob F, which raises the lever T and pump piston (see Fig. 3). A lost motion device 154, 155 allows the cam to swing round and so permit a full stroke of the pump on releasing the knob F.

Title: Sealing
Inventor: FELDMAN PETER BLANDFORD
IPC: B26F3/06
Filed: 1965-02-12
Abstract: 1,060,183. Seaming non-metallic sheet material. MONSANTO CHEMICALS Ltd. Jan. 7. 1966 [Feb. 12, 1965], No. 6153/65. Heading B5K. A seal 1 between a biaxially orientated thermoplastic synthetic resin sheet and a thermoplastic synthetic resin surface extends continuously around the edges of and between a series of perforations 4 in the sheet, the perforations 4 being spaced at intervals from one another so as to form a line of weakness along which the sheet can be torn so as to break the seal when required. Specified resins for the sheet are polystyrene, isotactic polyethylene or polypropylene, styrene copolymers, e.g. styrene-acrylonitrile copolymers, polyacrylates, polymethacrylates, polycarbonates, polyvinyl chloride and polyethylene terephthalate. The surface to which the sheet is sealed may be of any of the above specified resins or a toughened polystyrene or a styrene/ acrylonitrile/butadiene copolymer. Preferably the seal 1 is made between two biaxially orientated polystyrene sheets 2, 3. The orientated sheet may have a thickness of 0À0005-0À020 inch, e.g. a cover of 0À001-0À005 inch thickness is sealed to a container made from a sheet 0À01 inch thick. The perforations 4 may be circular, elliptical, square, rectangular or triangular. The major dimension of each perforation is 0À01-0À2 inch, preferably 0À02-0À1 inch. Preferably, the perforations 4 are evenly spaced with the distance between adjacent perforations being approximately the same as their major dimension. The seal may be produced by a heat scaling method or an adhesive may be used. The former method may be effected by an electrically heated tool 11, Figs. 2 and 3 (both not shown), having a line of teeth 12 with flat sealing surfaces 13 therebetween, both the teeth 12 and the surfaces 13 being coated with polytetrafluoroethylene to prevent the resin adhering thereto. A silicone rubber anvil 14 is provided. The operation is preferably performed at a temperature between 175‹ and 300‹ F. and at a pressure between 5 and 14 lbs. per square inch. A thermostat may be provided to maintain the tool at the sealing temperature. The tool may be maintained in contact with the sheet for up to 5 seconds, e.g. between 0À75 and 4 seconds. If it is desired to form a seal which is stronger on one side of the line of perforations 4, then the tool 11 or the anvil 14 is asymmetrically shaped or the anvil 14 is constructed of two materials of differing hardness to apply a greater pressure on one side. Alternatively, differential heating is employed, e.g. the tool 11 or the anvil 14 is constructed of two materials of different thermal conductivity. The seal of the invention may be used to seal a flat cover around three sides of a square container with a conventional seal on the fourth side to be used as a hinge. After sealing, the flat cover may be heat shrunk by radiation.

Abstract: 778,603. Centrifugal separators. DE LAVAL SEPARATOR CO. Feb. 29, 1956 [March 25, 1955], No. 6324/56. Class 23 A rotary bowl separator 15, discharging major and minor liquid components through outlets 15b, 15d respectively, has a float chamber 17 in the outlet 15d, the float 28 within the chamber rising on discharge of the minor component above the normal rate to cut off the feed to the separator and stop rotation of the bowl. The invention is applied to the separation of small quantities of water from oil, the bowl being first partly filled with water and the oil and water mixture being supplied to the bowl from a tank 10 by means of a pump 12 and pipe 14. The separated water discharging through the outlet 15d passes to the float chamber and during discharge at the normal rate overflows through notches 22b in an annular wier 22a to discharge to waste. If excessive quantities of oil are discharged with the water the rate of discharge increases, the chamber fills with oil, and the float rises to operate a switch 23 which cuts off the electrical supply to the motors 13, 16 driving the pump and the bowl respectively and causes a solenoid operated valve 18 in the pipe 14 to close. After adjustment of the feed rate, the separation is restarted by pressing a reset button 25. The wall 27a of the float chamber is transparent to enable the operator to observe and divert for collection oil which is discharging with the water at a rate insufficient to operate the switch. The switch is also actuated when abnormal amounts of water are discharged through the outlet 15d.

Abstract: 508,605. Coating with metals. DAEVES, K., and BECKER, G. March 1, 1938, No. 6443. Convention date, March 1, 1937. [Class 82 (ii)] To make an article which is assembled from a number of parts and has a corrosion-resistant surface, the parts are first fabricated from an iron alloy which is not resistant to corrosion and are assembled together to form the composite article, and chromium is then introduced into the surface of the composite article by diffusion from a chromium-containing gas. The articles are preferably heated in a furnace to 900-1100‹ C. and a current of chromous chloride gas, which may be produced by passing gaseous hydrochloric acid over red-hot ferrochromium or other chromium alloy or compound, is passed over them until a corrosionresistant layer has been formed on the whole exposed surface and in all joints &c. The chromium-containing gas may alternatively be produced directly in the furnace, e.g. from a chromium chloride salt. The manufacture of milk cans with their strengthening rings, foot ring, handles, &c. is described, the parts being made of soft ingot steel. After the introduction of the chromium, the cans may be polished. The Specification as open to inspection under Sect. 91 describes also the treatment of irregularly shaped articles and refers to screwthreads and pipe fittings. This subject-matter does not appear in the Specification as accepted.
