Patent GB-517775-A (GB)
Title: Aircraft construction
IPC: B64C35/00
Filed: 1938-07-28
Abstract: 517,775. Flying boats. MARTIN CO., G. L. July 28, 1938, No. 22495. Convention date, July 28, 1937. [Classes 4 and 113 (ii)] A flying boat has a high wing braced by struts pivoted to adjustable brackets on the hull, sponsons being pivoted to the same brackets. Provision for angular adjustment of the sponsons relatively to the hull is provided. As applied to a high wing flying boat, Fig. 1, the main plane is braced by inclined struts 16, 17 which are pivotally connected at their lower ends to adjustable brackets such as Fig. 11, to which the sponsons 25 are also pivotally attached, the forward struts 16 passing through wells 31 in the sponsons. Movement of the latter is controlled by twopart struts 18, 19 of which each part is pivotally connected to the wing strut, the upper part being pivotally connected to the main plane, and the lower parts, which incorporate shock absorbing devices and which are also adjustable in length, being connected to the sponsons, Fig. 3. The upper surface of the sponson corresponds to that of N.A.C.A 2300 series aerofoil whilst the lower surface is formed with a tapered step 32 so disposed as to co-operate with the forward hull step 11. The.means for adjusting the root end of the sponson relative to the hull may be manual or power means. As shown in Fig. 11, bracket 28, is vertically movable by rotation of a screw 71. The mounting of the after end of the sponson is similar but the bracket is wholly above the top surface of the sponsons. The dihedral angle of the spbnsons may be adjusted by means such as shown in Fig. 15 in which the effective length of the strut is variable by moving a piston 53 in a cylinder 52 by hydraulic means comprising an electric or hand pump 59 drawing fluid from a reservoir 58, a control valve 57 and pipe lines 55, 56. The sponsons may be used for load carrying and, as shown in Fig. 12, may be adapted to serve as fuel tanks. In this form the tank area is defined by main beams, root rib and outer rib. The tank is subdivided into a number of compartments by partitions 37 communication between which is effected by longitudinal corrugations 39 formed in the lower skin Fig. 3. The tip section is separately constructed and may be upwardly tilted and the bottom surface upwardly curved as shown at 44, Fig. 9. Alternatively the tip section may continue the taper of the main section. The under surface of the hull is also corrugated in order to cushion the water shock on alighting.

Title: Radio receiver and supply assembly
IPC: H05K11/02
Filed: 1957-07-16
Abstract: 856,753. Radio receiving apparatus. FABBRICA APPARECCHI RADIO E TELEVISIONE. July 16, 1957 [July 19, 1956, May 28, 1957], No. 22501/57. Class 40(5). [Also in Group XXXV] A portable radic receiver 20 operable from batteries contained withir the receiver casing is also operable from an external source of power such as the battery in a motor car. the external power supply being connected to a base member 2 to which the receiver may be connected by contacts 6, 7-8, 9 which fit into corresponding aperture in the receiver, the connections to the internal power supply being simultaneously broken. The base member 2 which is provided with a spring-loaded insulating cover which protects the contacts when the receiver is not mounted thereon is connected by cable 23 to the car battery and is attached to the dash-board of the car by means of brackets 24. The receiver preferably employs transistors so that it can operate directly from a low-voltage battery. The base 2 may also connect the output of the receiver to an additional loudspeaker in which case it may also disconnect the internal loudspeaker in the receiver. A further stage of amplification may be associated with the additional loudspeaker as described in Specification 855,966.
Patent GB-646905-A (GB)
Title: Improvements in and relating to control apparatus for electric blankets and the like
IPC: H05B3/34
Filed: 1948-08-26
Abstract: 646,905. Control systems for electric blankets. BRITISH THOMSON-HOUSTON CO., Ltd. Aug. 26, 1948, No. 22539. Convention date, Aug. 30, 1947. [Class 38 (iv)] [Also in Group XXXVII] A switch for opening the circuit of an electric blanket at a predetermined time and, if desired, sounding an alarm comprises a clock 2, which may be driven by a spring or (as shown) by a synchronous motor having a coil 4 and magnet 3, the motor also driving a cam 7 through gearing at the rate of one revolution in twelve hours. A spring arm 12 biasses a follower 11 against the cam 7, and carries a permanent magnet 14 on which is mounted a contact 13 which co-operates with a contact 15 on a spring arm 16 to control the blanket heating circuit. The arm 16 is biassed away from the arm 12, but is made of magnetic material so that when a button 17 attached thereto is depressed the contacts 13, 15 are held in engagement, an adjustable stop 19 in a fixed insulating bracket 20 limiting the movement of the arm 16 so as just to permit this engagement. In operation, the position of a cam step 9 relative to the follower 11 is adjusted by manual rotation of the shaft 8 by a knob behind the clock so that a pointer 7a indicates the desired time the blanket circuit shall be opened. When the cam step 9 reaches the follower 11 the arm 12 moves down under its bias and opens the circuit, and the arm 16 raises the contact 15 so that on continued rotation of the cam 7 the contacts 13, 15 do not re-engage. The follower 11 has a magnetic extension 21, which, when the arm 12 moves down to open the blanket circuit, comes adjacent the motor magnet 3 whereby it is vibrated to sound an alarm. This vibration can be prevented by a slidable wedge 22 which, when a knob 23 is pushed in, holds the extension 21 clear of the magnet 3 yet permitting the arm 12 to move sufficiently to open the contacts 13, 15. The blanket is maintained at the desired temperature by a bimetal strip 35 heated by a series coil 33, the strip controlling contacts 34 in the blanket circuit and being adjustable by a knob 36 to vary the blanket temperature. In a modification, Fig. 5, the cam 7b has a raised step 44 which raises the follower 11 just prior to its moving down the step 9, thus causing a contact 39 on the extension 21 to engage an adjustable contact 38 on an extension 37 of the bracket 20 and shunt the heater 33 by a resistance (Fig. 6, not shown). The blanket is thus raised to a higher temperature before it is switched off, so as to provide more warmth in the early hours of the morning.

Title: Improvements in or relating to safety or relief valves
IPC: F16K17/10
Filed: 1928-08-03
Abstract: 320,974. Dewrance, Sir J. Aug. 3, 1928. Valves controlled by pilot or relay valves safety valves. -A safety valve for fluid-pressure systems, of the type comprising a main valve 5 and an auxiliary valve 9, has the auxiliary valve spring-loaded, in opposition to the pressure in the system, to close, a passage 10 in communication with the outlet side of the valve. The auxiliary valve is opened by electromagnetic means when the pressure in the system reaches a predetermined maximum, and thus releases the pressure on the upper side of a ported or leaky piston 6 formed integral with the main valve, the latter then being automatically lifted by the pressure acting upon a portion of its lower face, the upward movement being limited by a stop 8. The piston 6 slides in a cylindrical chamber formed by the lower portion of the passage 10 in which the auxiliary valve is located. The auxiliary valve is opened by a solenoid 13 which is energized, on the attainment of a predetermined pressure, through a relay (Fig. 3), this being in turn controlled by a switch (Fig. 2) actuated by a Bourdon tube 18 in communication with the pressure system, the free end of the tube being connected by links to a pivoted contact arm 22. When in the position shown in Fig. 2, the arm 22 causes the coil of the relay to be short-circuited but excess pressure will cause contacts 24, 25 to close thereby connecting the coil of the relay across the mains 31, 32 through a series resistance 34, thus operating the switch and closing the solenoid circuit to actuate the valve. The pressure at which the valve opens may be varied by changing the tension on the spring 33 (Fig. 2) or by adjusting the position of the contact stud 25 or by both means in combination.

Patent GB-289316-A (GB)
Title: Improvements in method of making socketed head screws
IPC: B21K1/46
Filed: 1927-08-29
Abstract: 289,316. Lyman, C. E. Aug. 29, 1927. Screws.-Grub screws with an angular socket to receive a key wrench are formed by inserting a cold metal slug entirely within a die cavity, driving an angular punch into the mouth of the die a predetermined distance whilst holding the slug stationary, then moving the die with the punch causing the metal of the slug to be extruded from the die cavity in a direction opposite to the movement of the die and punch so as to form the angular socket, and subse. quently threading the outside. The slugs cut off from a bar, are socketed at 21, Fig. 5, capped at 22, rounded at 23, tapered at 24 and threaded at 25. The die 6 is slidably fitted in a sleeve 12 in the front 13 of the machine and is pressed forward by a spring 14, a pin 15 on the ejector plunger 16 projecting into the die cavity. The slug 1 is pushed into the die cavity by a spring feed pin 4 on the punch holder 3 which is mounted on the reciprocating ram of the machine and is raised and lowered to bring the feed pin 4 and angular punch 5 alternately into line with the die cavity. The angular punch 5 is guided by a sleeve 10 in the punch block 9 and projects slightly beyond the end of the punch block. As the latter moves from the position shown in Fig. 8 to that shown in Fig. 9 the die 6 also moves and the metal of the slug is extended from the die cavity over the angular punch 5, thereby forming the angular socket in the blank and the pointed end 17 of the ejector pin 15 cupping the blank at 22. The sleeve 10 is actuated by a block 100 to strip the blank from the punch. The formed blanks are then fed to a screwing machine which rounds off the end at 23, bevels the cupped end at 24 and rolls or cuts the thread 25.

Filed: 1973-05-12
Abstract: 1475282 Fuel injection system CAV Ltd 6 May 1974 [12 May 1973] 22719/73 Heading F1B A fuel injection system comprises an electrically controlled Piezo-electric crystal actuator 30, a movable member 22 the movement of which displaces fuel which passes through spray orifices 14, and sensing means 36 for detecting the movement of the member 22 and providing a signal to the actuator 30 when fuel delivery is to cease. The actuator comprises a stack of Piezo-electric crystals 31 and a piston 32, which when the stack is energized pressurizes the space between a piston 17 and a control valve 18. In addition a valve-member 27 is moved from a position in which it allows communication of opposite ends of the cylinder containing member 21 to a position in which the ends are isolated. As a result, the pressure of fuel in accumulator 24 fed by an engine-driven pump 25 causes the member 22 to move against its spring bias. Both the control valve 18 and piston 17 are moved upwardly by virtue of the pressure differences acting on their surfaces allowing fuel to pass from the cylinder of the member 22 through a passage 20 to the injector 11. A valve-member 12 of the injector lifts away from its seating allowing fuel to pass through spray orifices 14. When the sensing means 36 has detected that member 22 has moved a predetermined distance the actuator is de-energized and the control valve 18 and piston 17 return to their former positions to prevent further delivery of fuel.
