Title: Improvements in or relating to apparatus for indicating and/or recording the time average of the pressure of the working fluid in piston engines
IPC: G01L23/02
Filed: 1924-12-01
Abstract: 250,156. Geiger, J. Dec. 1, 1924. Steam-engine and like indicators; pressuregauges, indicating means for; with damping- arrangements.-To determine the time average pressure within the cylinder of a piston engine a piston 2, which is subjected to the fluid pressure in the cylinder through a flexible pipe connection, is connected by a rod 34, link 36, a lever 5 and a link 17 to a rocking shaft 37 carrying a toothed arm 7 meshing with a pinion 8 on a shaft 38 provided with an inertia mass formed by a fly-wheel 3. The piston is normally held in a certain position of equilibrium by an exchangeable spring 4. A flat spiral spring acting directly upon the heavy fly-wheel may replace the spring 4. The magnification of the movement of the piston-rod may be varied by adjusting the position of the link 17 in the connection between the lever 5 and the rocking shaft 37. A diaphragm or a Bourdon tube may be used in place of the piston and the spring or in place of the piston alone. The movement of the fly-wheel may be damped by arranging the wheel in a chamber filled with oil or a damping device such as a series of blades turning in a chamber filled with oil or a cylindrical drum adapted to move in a closely-fitting casing may be fitted. The piston 2 moves in a cylinder 42 provided with a water jacket 43 and to prevent carbon being deposited on the end of the piston and in the cylinder 42 an exchangeable connection member 18 between this cylinder and the flexible tube leading to the engine cylinder is provided with one or more holes 19 by which the hot gases may be deflected from the wearing surfaces. Annular spaces 20 in the cylinder at the rear of the piston communicate with the outside of the casing and provide an escape for any gases passing the piston. Lubricant is forced between the piston and the cylinder through a non-return spring-pressed valve 64 by the pressure oil supply of the engine or by a hand pump 62. Adjustable tubular members 22 of yielding material act as buffers to limit the range of movement of the piston. The pressure is indicated by a pointer directly connected to the fly-wheel and a permanent record is made on a rotating recording disc by a writing point 23 actuated from an intermediate part of the transmission gear. The point 23 in the no-load position moves clear of the disc.

Title: Electrical connector for use in combustible gas environments
IPC: H01R13/527
Filed: 1964-01-31
Abstract: 1,057,903. Two-part couplings. PYLENATIONAL CO. Jan. 31, 1964 [July 16, 1963], No. 4265/64. Heading H2E. A pin-and-socket electrical connector, for use in the environment of a combustible gas, comprises a socket with an elongated inlet into which the mating pin 23 slides into engagement in the socket 37, the inlet being lined with a sublimate material 46. The line has a length equal to more than half the axial length of the inlet. Shortly before pins 23 engage socket contacts 37 an arc may be drawn between the metal elements which will ignite any combustible gas in the bores. The energy of the burning gas may be used to volatilize the material of sleeve 46, the absorption of energy causing a temperature reduction, such that the burning gas is brought below its ignition temperature. The lining material is also chosen so that on sublimation it generates combustion extinguishing gases to accelerate the extinction of the burning gas. A combination of a cross-linked organic polymer and a dienic polymer is a suitable material for the lining.

Title: Improvements in and relating to dispensing devices
IPC: B22D39/02
Filed: 1962-02-05
Abstract: 964,133. Casting metals. G. FRIES, A.G. EYSSEN, and L. ROMEN, [trading as J. S. FRIES SOHN]. Feb. 5, 1962 [Feb. 10, 1961], No. 4423/62. Heading B3F. [Also in Division B8] Measured quantities of molten metal for use in pressure casting are displaced over the spout 26 of a crucible 18 by the downward movement in successive steps of a plunger 24 and after each step the plunger is raised slightly so that the metal falls in the narrow neck of the crucible to a level 21 which is within the furnace 14 and which presents a minimum surface to the air. The plunger 24 is counterbalanced by a weight 34 attached by a cable 36 to a rod 28 and the rod has spaced studs 40 which are engageable by spring-loaded or counterweighted pawls 42, 44. The pawl 42 is pivoted on the piston-rod 64 of a piston 66 of a cylinder 68, and the pawl 44 is pivoted on a cross-member 56 secured to a cylinder 76. When pressure fluid, such as compressed air, is supplied through a conduit 90, it is fed below the piston 78 in the cylinder 76 connected to the cross-member and passes through a conduit 94 to the space above the piston 66. The cylinder 76 moves down and the pawl 44 lowers the plunger 24 until the level of molten metal rises to the level 23 of the spout. The piston 66 also moves down and its longer stroke, through the pawl 42, causes the plunger to move further down and displace the required quantity over the spout; the lower pawl 44 meanwhile clicks over a stud 40. The supply of compressed air is then reversed and both pawls move up; the plunger follows the movement of pawl 44 until it is arrested and the upper pawl 42 then clicks over a stud 40. A stop in the path of the weight 34 or of the top 40 may limit the downward travel of the plunger. Slotted nuts 74 and 84, which can be opened and closed by a screw 86, adjust the range of movement of the pawls.

[Also in Division E2] A universal joint for a vehicle rear-view mirror which will accommodate vertical and horizontal misalignment has a detent so that if the mirror is swung inwardly to avoid an obstruction it will re-engage the detent when moved back and so be correctly positioned. The mirror is carried by arms 25 and is supported from the vehicle by arms 15, 16. A detent plate 37 forming part of the joint has protuberances 37a engaging projections 38 on the arm 25 and has protuberances 37b engaging ball-headed elements 39 to accommodate any misalignment. The elements 39 are mounted on an adjustment plate 40 threaded on a hinge 33 and locked by a nut 33b whereby the mirror can be set at any required angle. The projections 38 are not seated so deeply in the protuberances 37a as are the elements 39 in their protuberances 37b, this ensures that when the mirror is swung about the bolt 33 the elements 38, 37a will disengage and subsequently re-engage. A spring 42 prevents looseness in the joint when the mirror is swung inwardly. In other embodiments, the spring is replaced by a resilient pad, or the detent plate 37 may carry projections instead of the seatings 37a, 37b. The projections may be hardened pins.
