Title: Strainer for Nightsoil from Pails as used in Military Latrines and elsewhere.
Inventor: METZNER ALBERT EDWARD
IPC: A47K11/04
Filed: 1918-03-22
Abstract: 122,549. Metzner, A. E. March 22. 1918. Sanitary pails.-In a sanitary pail for removing nightsoil from military latrines &c. of the type comprising a perforated inner vessel for separating liquid from solid matter, the inner vessel has a hinged bottom for discharging the solid matter to the destructor. The perforated inner vessel D is supported by its handles in the solid outer vessel A, and the hinged bottom G of the inner vessel is held in place by a catch J forming part of a rod passing through bearings K and provided with a handle by which it can be turned to release the bottom. When the vessel D is full of solid matter, it is placed over the opening of the destructor and the matter allowed to fall into the destructor by turning the handle J, thus releasing the hinged bottom G.

Abstract: 1431411 Anti-theft lock VOLVO PENTA AB 4 Feb 1974 [9 Feb 1973] 05104/74 Heading E2A  In an anti-theft lock for a boat having wheel steering, the latter, having a cog wheel, engages a steering cable, having a cogged surface formed thereon, to actuate a rudder. the steering is locked by a slidable bolt 23, Fig. 2, having a portion 24 provided with teeth 25, being moved into engagement with the cogged surface of the cable 13. The latter passes through a housing 11 and has a core 14 with steel wire 15 helically wound therearound to form said cogged surface. The bolt 23 is mounted in a portion 17 of the housing 11 and, having a flange 31, is urged by a spring 32 away from the cable 13. A member 28 is rotatably mounted on the bolt 23 and carries a member 34 which when the bolt 23 is moved axially, is engagable with stops 35, 36 on the housing portion 17 to retain the bolt in contact with the cable or to prevent the bolt from contacting the cable. The bolt may be connected, via the member 28, with an ignition lock 37, Fig. 3, having a cylindrical member 38 which is rotatable by a key (not shown) to allow a contact 41 on the cylindrical member 38 to connect with an electrical supply 39 and to rotate the member 28.

Title: Improvements in or relating to thermionic amplifiers
IPC: H03F3/28
Filed: 1933-02-27
Abstract: 402,964. Valve amplifying circuits. TELEFUNKEN GES. FUR DRAHTLOSE TELEGRAPHIE, 12, Hallesches Ufer, Berlin. Feb. 27, 1933, No. 5965. Convention date, Feb. 25, 1932. [Class 40 (v).] Relates to push-pull amplifiers in which the valves are active in turns for alternate half-waves and the grid bias is determined by the voltage-drop in a resistance 6, with smoothing-condenser 7, in the plate circuit. In known arrangements of this kind (Fig. 1, not shown) the grid bias ceases to be independent of amplitude if the amplitude is so great that the plate current falls to zero during negative halfwaves (Fig. 2, not shown). According to the invention this is prevented by the use of a device for maintaining a constant voltage across the resistance 6 ; thus, the resistance may be shunted by a glow discharge lamp (Fig. 3, not shown) ; or the grid bias may be tapped off a resistance 10 in series with an iron-hydrogen or like constant-current resistance 10 ; or there may be a common constant-voltage device together with two constant-current devices, one for each valve, (Fig. 5, not shown).

Title: An improved mechanical infinitely variable torque converter
IPC: F16H33/08
Filed: 1954-03-02
Abstract: 787,505. Variable-speed gear. AUTO UNION GES. March 2, 1954 [March 3, 1953], No. 6098/54. Class 80 (2). In a variable-speed gear, for a motor-vehicle, of the kind in which masses 17, 20 are rotated by an input shaft 5 about eccentric axes on an intermediate shaft 12 spring-coupled to an axledriving output shaft 23, such rotation developing alternating opposite drive impulses of which those in the direction not required are suppressed by a one-way detent, the said detent comprises a helix, e.g. 27, embracing the shaft 12, secured at one end to the fixed housing 7, and having coupling means for moving its other end into frictional engagement with the shaft 12. As shown, two detent helices 27, 28 of exponentially tapered cross-section are provided, acting in opposite directions under the selective control of a forward, neutral, reverse and park-lock lever 40, which allows the free end of either one helix to be contracted into contact with the shaft 12 whilst simultaneously expanding that of the other, by oppositely turning flared sleeves 33, 37, each surrounding a helix and connected to its free end by a light spring 31 which gives the helix end an initial contracting stress. Lever positions 41, 42, 43 give forward, neutral and reverse, whilst the transverse position 44 allows both detents to act simultaneously for parklock. The helices 27, 28 may be formed by slitting a tube and may be single or double start. In Fig. 1 the masses 17, 20 are formed on planets 16 carried by the intermediate shaft 12 and meshing an internally toothed ring 22 on a flywheel 8, driven through chain reducing gear 3 by an engine 1. In Fig. 6 (not shown) the masses are carried on arms linked together and to a crank-pin on the flywheel 8, whilst in Fig. 7 (not shown), the masses are on planet-sprockets chain-geared to an input sun. The spring coupling connecting the intermediate and output shafts 12, 23 comprises a single rectangular sectioned forwardly tapered torsion bar 45, secured to the output shaft 23 and engaged by internal driving ribs 46, 47 on the intermediate shaft 12 over a contact length which increases . with increased deflection, due to the taper of the bar. Maximum deflection is 180 degrees divided by the gear-ratio (4 to 1). In Fig. 4 the torsion bar 45a has three laminations which successively contact steps of driving ribs 46a, 47a. In Fig. 8 the shafts 12, 23 are coupled by a helical torsion spring 65 of taper cross-section, surrounded by a flared sleeve 67. The spring is contracted by relative forward acceleration of the shaft 12 and expanded by its retardation.

Title: A ceramic dielectric material
IPC: H01G4/12
Filed: 1960-02-22
Abstract: A sintered ceramic dielectric material suitable for use in capacitors comprises two phases, one of which is formed by ferro-electric tetragonal barium titanate and the other is formed from ferro-electric mixed crystals which contain barium titanate, the Curie point of the mixed crystals being lower than that of the tetragonal barium titanate and the size of the crystals of the individual phases being smaller than 3\m.  Substances (not oxides) may be added which are capable of forming ferro-electric mixed crystals with barium titanate and others may be added which restrain the growth of crystals so that the size of the crystals of the individual phases is less than 3m .  Suitable materials for addition are stannates, zirconates or titanates, for example MgSnO3, MgZrO3 and MgZrSiO5, and these may be subjected to a preliminary burning (at above 1300 DEG C.) to improve their growth restraining effect.  Fe and Fe2O3 may be added to restrain growth during the final sintering.
