Patent GB-1286616-A (GB)
Title: Gate arrangement
Inventor: LOOTS GILLIAM
IPC: E05F13/04
Filed: 1970-12-07
Abstract: 1286616 Gate operating mechanisms; catches G LOOTS 7 Dec 1970 58060/70 Headings E2A and E2M An automatic gate arrangement has means whereby the gate can be opened by a motor car, consisting of a rod 28 extending vertically between the gates 10 when closed and connected via a bar 16 to crank mechanisms which open the gates when the rod is pushed over, and the bar 16 thus rotated, the length of time for which the gates remain open being determined by two receptacles 104 mounted at opposite ends of a tilt arm 100, a duct 106 between the receptacles 104 allowing the flow of fluid between them depending on their relative positions, this fluid flow which occurs when the gates are opened and the tilt arm 100 tilted eventually causing the gates to close. As shown in Fig. 4 the rod 28 has an abutment bar 32 coaxial with it below ground level and also connected to the bar 16, a drawbar 38 pivoted to this having ropes 40 and 42 connected to it which run to the crank mechanisms, one to each door and connected thereto by arms 58 and brackets 60, the crank arranged such that when rod 28 is pushed over and ropes 40 and 42 thus pulled up the gates open. The closing of the gates under the action of springs 57 is prevented by the short arm 74 of a bellcrank 70 which cooperates with the abutment member 32 to hold the gates open. The opening of the gates also causes, by means of wire ropes 114 and 108, the tilting of tilt member 100 about its axis 102 to the dotted line position shown and so the liquid flows from the right hand to the left hand receptacle, the weight acting through chain 118 of the left hand receptacle, which increases as the liquid flows into it, eventually being sufficient to move the bellcrank out of abutment with the abutment member 32, this allowing the springs 57 to close the gates and tilt the arm 100 back. The rope 108 is such that it has enough slack in the fully open position of the gates to allow this to occur. Two bellcranks are provided so that the gates may be opened either way. In addition to the rod 28 two inverted U formations in the bar 16, designed to be contacted by the vehicle's wheels, also serve to open the gates. Catches provided on the gates to prevent them from continuing to swing when shut consist of two bars 122 and 124 mounted to the gate by, and pivotable on, a stud 126, a spring holding them against an abutment lug 127. Feet 132 and 134 which can swing freely inwardly are mounted at the lower ends of the bars and engage the stop bar 36 mounted on bar 16. The strength of the spring 130 and the spring 157 closing the gate are adjusted so that this can take place.

Title: A device for continuous manufacture of patterned paper
IPC: D21F1/44
Filed: 1967-12-21
Abstract: 1,220,070. Papermaking. HOKKAI SEISHI K.K. 21 Dec., 1967 [16 March, 1967; 27 May, 1967; 1 Aug., 1967], No. 58259/67. Headings D2A and D2B. A device for the continuous manufacture of patterned paper comprises a movable machine wire (14), means (10) for distributing stock (12) uniformly on the wire, first means (18) to remove the bulk of the water from the stock, a patterning belt (24) having perforations and moving at the same speed as the wire, means (28) for ejecting water under pressure through the perforations and on to the web, a waterpressure equalizer (36) between the ejector means and the patterning belt, second means (34) for removing the ejected water after it has passed through the web and the belt, and means (42) for heating the web to dry it. As described, the headbox has a variable slice (Fig. 2, not shown), the ejector means is an array of shower pipes (Fig. 3, not shown), the pressure-equalizer is a metallic screen, the second dewatering means is an array of suction boxes, the web is couched on to a felt 40 and transferred to a Yankee drier 42, from which it is creped by a doctor 44. Reference is also made to embossing, chemical softening by the use of a surface-active agent such as a fatty-acid amide or alkylamine. Non-heatshrinkable fibres may be mixed with heatshrinkable fibres, e.g. heat-stretched fibres of polyacrylonitrile or polypropylene. When such a sheet is heated the shrinkable fibres shrink, to yield a soft cloth-like paper. Water-resistance may be improved by the use of ureaformaldehyde, melamine, epoxy, polyethylenimine or dialdehyde-starch resin, or waterrepellancy by silicone resin, wax or stearatochromic chloride. These treatments can be done by adding the agents to the pulp, or by impregnating the paper after drying. Patterned and non-patterned papers may be laminated together by laying the patterned paper on a wet web and rolling them together. In a first Example, the stock comprises rayon, "pulp" and polyvinyl alcohol fibres. In a second Example the patterned paper from the first is laminated to a wet web of "pulp" only, at a water content of 88%.

Title: Closure flange feed apparatus
IPC: B21D51/38
Filed: 1971-12-23
Abstract: 1353790 Jointing by stamping AMERICAN FLANGE & MFG CO Inc 23 Dec 1971 [14 Jan 1971] 60059/71 Heading B3Q Closure flanges 47, Fig. 10, are fed to an anvil 56 which co-operates with a curling anvil 60, Fig. 13, to secure the flanges in container wall openings 55 by apparatus comprising a slide 7, Fig. 1, reciprocably movable on a base 1 by a piston and cylinder assembly 3, a flange receiving member 33 mounted on the slide for relative movement thereto, a shoot 43 for feeding flanges to the member 33 when the slide is in a retracted position, and a spring-biased presser 36 overlying the member 33 and operatively connected to the assembly 3 such that when the slide is in a fully advanced position a flange is urged downwardly on to the anvil 56. In operation a closure flange is fed down the shoot 43 on to the member 33 where it is received in pockets 15 is arms 13 and 14 of the slide. The piston-rod 5 of the assembly 3 is then advanced causing the slide 7, the member 33 and the presser 36 to move towards the anvil 56. As the slide advances a guide 17 prevents entry of a following flange from the shoot 43 on to the member 33. As the piston-rod continues its movement, Fig. 10, stop nuts 24 on rods 22 contact a wall 2 and terminate the movement of the member 33. However the slide 7 continues to advance causing the downwardly spring- biased presser 36 to move into contact with the top of the flange due to the engagement of cams 42 and 35. On completion of the piston-rod stroke, the pockets 15 are vertically aligned with the anvil 56 and the flange is pulled off the member 33 and urged on to the anvil by the presser 36. The piston-rod is then retracted and the anvil 60 lowered to force the flange base against the anvil 56 and the container wall 53 to depress a compression ring 57. Continued downward movement of the anvil 60 curls the upper part 51 of the flange outwardly about the upper end of the wall opening 55.

Title: Improvements in photoelectric measuring devices
IPC: G01J1/16
Filed: 1969-12-10
Abstract: 1287158 Photo-electric apparatus MACHINES AUTOMATIQUES MODERNES 10 Dec 1969 [27 Dec 1968] 60260/69 Heading G1A [Also in Division G4] A photo-electric measuring system of the type in which a light beam is divided, one half going direct to a reference photo-electric cell and the other to a data photo-electric cell via a specimen under examination, is characterized in that the light beam is chopped, the outputs of the two cells are compared and the output of the reference cell is progressively attenuated in steps until it matches that of the data cell. As described a light beam 1, is chopped 6, 7 and divided 2, and the two halves f 1 , f 2 , pass direct to a reference photo-sensitive diode 3, and via a specimen 4 to a data photosensitive diode 5. The output signals PN from these are arranged to be of opposite polarity and they are combined in a resistor network C to produce a signal E having an amplitude given by E = aP+bN, where a depends upon which of a set of resistors 16, 17, 18, 19, 20 is operative, and b depends upon a resistor 15. The signal E is sampled at its mid-point, shown dotted, E, by a contact 24a under the control of pulses derived from the reference photo-sensitivie diode 3, and the resulting signal is differentiated 22, 23 and amplified 25 to produce a signal RA. Alternate pulses of this signal RA, namely those that occur when the output of the reference photo-sensitive diode 3 is positive, are gated 27, 28 to a transistor counter S which sequentially closes contacts I, II, III, IV, V, so as to reduce the factor a in the above equation. The signals shown in the drawing occur when the output E is determined predominantly by the reference photo-sensitive diode output. As the contacts I, II, III, IV, V, are sequentially closed, the amplitude of the signal E will decrease and will eventually pass through zero effectively to cause a change of phase of the signal E. When this occurs no further pulses pass the gate 27, 28 so that stepping of the counter S stop and the measurement is complete. The result of the measurement is determined by the last contact closed and may be printed RG or displayed. Calibration of the maximum and minimum limits of the system is achieved by potentiometers 36, 38 and specimens of known composition.

Title: Waveguide junctions
IPC: H01P1/213
Filed: 1979-04-18
Abstract: A coaxial/waveguide hybrid junction has two coaxial ports 1, 2 and dual-mode waveguide ports. The junction shown is an analogue of a directional coupler since orthogonal modes in the symmetrical waveguide each excite the co-axial ports 1, 2 in quadrature. If the coupling is rotated through 45 DEG  such that the co-axial ports lie in the centres of opposite walls, an analogue of a hybrid-T is obtained, the co-axial ports being excited either in phase of in antiphase by the orthogonal modes. The waveguide section may operate in evanescent mode so that a substantial reduction in size and mass results. The junction can be used alone, for an aerial feed for example, or, if two are coupled by their waveguide ports as shown, as a directional filter in which a series of carrier frequencies are dropped off (or collected) one at a time. A combined equaliser and filter construction is shown. <IMAGE>
