Title: Improvements in or relating to self-sustaining gear for hoisting devices
IPC: B66D3/10
Filed: 1927-12-02
Abstract: 282,732. Faure, S. Dec. 30, 1926, [Convention. date]. Self-sustaining gear.-A self-sustaining gear comprises a pawl 1 having a slotted connection 3 with its pivot 2 and a sector 4 pivoted on the pawl at 5. Fig. 7 shows the parts in position for hoisting, during which the appliance functions as an ordinary pawl. When the hoisting effort ceases, the pressure of the load causes the pawl to swing bodily in a clockwise direction into the position shown in Fig. 8 in which the pin 2 occupies the lower end of the slot. This movement allows the sector to fall into the position shown. In this position the pawl functions as a retaining pawl but it is in an unbalanced position and when the hoisting-rope is pulled slightly to relieve the pressure, the pawl moves into the balanced position shown in Fig. 1 which allows free lowering of the load. On reversing the drum to recommence hoisting, the sector is rolled from the position shown in Fig. 1 to that of Fig. 7, thus allowing the pawl to re-engage the teeth for the hoisting operation.

Title: Improvements in and relating to a device for recording the density of a liquid
Inventor: RAMSAY BERNARD WALTER
IPC: G01N9/18
Filed: 1953-11-25
Abstract: 761,880. Electric indicating systems. IMPERIAL CHEMICAL INDUSTRIES, Ltd. Nov. 5, 1954 [Nov. 25, 1953], No. 32700/53. Class 40 (1). In a device for recording the density of a liquid using a hydrometer, movements of which are sensed by a ferromagnetic wire carried thereby and a coacting coil system connected through a bridge circuit to the recorder, linearity of the recorder response relative to liquid density changes is achieved by appropriate dimensioning of the wire and the circuit components. As shown, a glass hydrometer 12, Fig. 4, floats in the liquid whose density is to be measured, in a constant level chamber 14. The hydrometer stem carries an iron wire enclosed in a corrosion resistant sheath 13 disposed within a transmitter coil system 15, and a resistance thermometer 16 used for temperature compensation is disposed in a sheath in the liquid inlet to the chamber 14. Circuitry, Fig. 2. The coil system 15 comprises an A.C. energized primary coil 2 mounted on or inside a pair of similar secondary coils R<SP>1</SP>, R<SP>2</SP> connected in series aiding in a bridge circuit R<SP>1</SP>-R<SP>8</SP> the component values of which are chosen as disclosed in the Specification to achieve linearity of the recorder response. The galvanometer 3 of the self-balancing recorder is connected across the bridge output in series with a temperature compensating voltage applied at 4, 5. The bridge is balanced by automatic adjustment of R<SP>6</SP>, and R<SP>4</SP> is adjustable for zeroizing the recorder. The rectifiers 7, 8 permit use of a D.C. recorder but may be dispensed with, Fig. 1 (not shown), for A.C. operation. Temperature compensation, Fig. 3. The compensating voltage at 4, 5 is derived from a bridge one arm of which includes the winding 9 of the resistance thermometer 16, Fig. 4. The bridge is fed from the same A.C. source 10- 11 which feeds the coil 2, Fig. 2, through a potentiometer R<SP>9</SP> ganged with the bridge balancing resistor R<SP>6</SP>, Fig. 2.

Title: Pressure Relief Valves.
Inventor: BAKER PAUL WILLIAM
IPC: F16K17/10
Filed: 1966-07-21
Abstract: 1,150,230. Valves; energy-absorbing devices. MINISTER OF TECHNOLOGY. 21 July, 1966, No. 32770/66. Headings F2E and F2V. [Also in Division G3] A quick - acting pilot - operated pressure relief valve has an inlet 3, communicating with the zone whose pressure is to be controlled, and an outlet 15. A piston valve member 4 seats at its lower end on a resilient ring 12 and defines a chamber 13 at its upper end. When the valve is closed, a resilient ring 9 thereon engages a seat 8 to seal chamber 13. The latter communicates with the said zone via a three-way solenoidoperated valve (not shown). A pressure switch having set-point and indicating needles senses the pressure in the zone and controls the solenoid. When the pressure reaches the set point, the solenoid vents chamber 13 so that valve 4 rises under inlet pressure against a spring 21. After the valve has risen a small distance, balls 24, 25 are permitted to move outwardly into a larger diameter portion of a sleeve 19 thereby releasing the valve spindle 5 from the load of spring 21. The valve therefore accelerates upwardly into engagement with a collapsible, hollow, aluminium plug 28. The collapse of plug 28 allows a  pin 31 to fall, thereby indicating that the valve has opened. The plug 28 is replaced when the valve is reset. The spindle 5 is guided in bearings 6, 7 and the valve may be lifted manually by rotating hand wheel 18 to cause plate 32 to engage circlip 33.

Abstract: 307,374. Molins, W. E. Dec. 5, 1927. Paper bags, making. - Relates to block bottom paper packets and a method of making them. Rectangular blanks 3, Fig. 1, are fed from a magazine by an oscillating suction device 5, which pulls down the lowermost into contact with a continuously rotating roller' 6, a roller 7 on an oscillating -arm pressing it down so that it is fed by rollers 9 against a stop 10. Cutting rollers 11, 12 form slits 13, Fig. 2, and on the stop 10 being raised, the blank is fed against a stop 16. The stop 10 is raised by the action of a contact piece 18 on a lever 17 in contact with a lever 20 on the stop. Gumming may be effected as described in Specification 24306/14, [Class 100 (i), Feeding and delivering webs &c.]. A roller 14 is raised by the same movement to press the blank against a continuously rotating roller 15 to forward the blank, while the former 1 is in its raised position. The former now moves downwards, bending the blank into a U formation. An oscillating folder 22 makes folds about the lines 23 while commencing the side folding, and a smoothing device flattens this portion of the side upon the plunger. Curved folders 27 turn down the flaps 26, which may have been gummed previously, upon the inner folds, to produce a packet as shown in Fig. 3, having a rectangular external narrow side flap. The packet is stripped from the former into a heating box. Specification 231,758, [Class 100 (i), Feeding and delivering webs &c.], is referred to in the Provisional Specification.

Abstract: 534,067. Directive wireless systems; aerials. STANDARD TELEPHONES & CABLES, Ltd. Dec. 22, 1939, No. 32812. Convention date, Jan. 3. [Class 40 (v)] For radiating or receiving centimetre waves, a two-wire or coaxial feeder, or a dielectric guide, is terminated by a flared horn. Fig. 1, having a radial length and aperture so related to the flare angle # 0  that the " beam angle 29, Fig. 13, is a minimum, and the power gain (as compared with a single dipole) a maximum. In Fig. 1 a rectangular horn is connected to a " hollow pipe" section 18, of dielectric or conducting material, and is energised by, or feeds, a rod antenna 14 at the end of a coaxial feeder 10, 12. The horn may be circular or pyramidal in section. The sides may be straight, as shown, or concave, convex or hyperbolic. The horn acts as a directive radiator giving a response, Fig. 13, which is proportional, inter alia to the flare angle # 0 , the length of the side, and the working wavelength. Analyses are given of the radiating and directional properties of the horn for different forms of " guided " wave, such as the H 0,1  type, Fig. 5, and the R 1,0  type, Fig. 8, and of the conditions under which the production of undesirable secondary " lobes " of free-wave radiation can be prevented or minimised, particularly when the invention is applied to blind-landing equipment for aircraft. Alternative shapes of horn and of methods of coupling it to transmitting or receiving apparatus are shown in Figs. 2 and 3. Graphs are given which relate the optimum flare-angle # 0  and the ratio of the radial length P 1 , Fig. 4, of the horn to the working wavelength # for a given range of beam angles (Fig. 33 not shown) ; also the relation of the power gain to the dimensions of the horn (Fig. 34 not shown) ; also the optimum design of horn for a given power gain both for the H 0,1  and H 1,0  type of guided wave (Fig. 36, not shown), Using H 1,0  waves with an increase in the flarehorns of equal length. angle tends to sharpen the principal lobe of the beam and to increase the secondary loges ; whilst for horns of constant flare-angle, the width of the beam tends to increase with the length P, of the horn. The H 1,0  wave on the other hand, gives a clear-cut beam for flare-angles less than those required for maximum power gain, but produces an irregular beam for wider flare-angles.
