Title: Improvements in levelling apparatus
IPC: G01C9/22
Filed: 1933-07-03
Abstract: 421,829. Levels. BROOK, H. R., Westcarr, Bushey Heath, Hertfordshire. July 3, 1933, No. 18776. [Class 97 (ii)] In a liquid - level in which two vertical tubes mounted on suitable base plates are connected together by a flexible pipe and the system partly filled with liquid, the upper ends of the vertical tubes are sealed from the atmosphere by slack membranes of rubber, skin, silk or other flexible material. As shown, the membrane c covers a vent hole t in the handle member b, which is screwed to the top of the casing a supported on the base d. A graduated glass tube g in the casing a communicates at the top with the space beneath the membrane c and at the bottom with a flexible tube f leading to the second vertical tube. The latter is shaped to have a large cross sectional area at the liquid surface. The membranes c serve to prevent loss of liquid from the system and also to damp extreme movements of the liquid. According to the Provisional Specification, one of the vertical tubes may be provided with a pointer or spring clip to be adjusted to the level of the liquid surface or the tube may be slidably mounted on a stand. The variation of liquid volume due to temperature or evaporation may be compensated by a watertight screw projecting into the liquid.

Abstract: 848,591. Mechanical toys. METTOY CO. Ltd. May 11, 1959 [June 12, 1958], No. 18798/58. Class 132(3). In a toy, a device simulating an hydraulic cylinder and its ram comprises a block connected to one of two relatively movable parts of the toy, a rod connected to the other of these parts and passing slidably through the block, and a friction pad carried by the block which engages the rod and offers resistance to the sliding movement of the latter. In a two decked car transporter vehicle, the friction pad' comprises a rubber sleeve 13, Fig. 2, fixed in a block 9 either by a retaining sleeve 14 or by spinning over the material of the block. Alternatively, the sleeve 13 can be replaced by a rubber grommet engaging an inwardly projecting annular flange provided on the block. In a vehicle with a tipping body, the friction pad comprises a rubber sleeve 22, Fig. 4, loosely mounted on a pin 21 and compressed against a sliding arm 19, the pin 21 also pivotally supporting a block 20. In each of the above cases, the block may be formed by a metal die casting or may be moulded or machined from synthetic plastic and the rods representing the rams may be of wire or may be turned rods or pins. Specification 831,015 is referred to.

Filed: 1925-07-30
Abstract: 257,397. Paget, F., and Horseman, S. H. July 30, 1925. Pressure and roller-separating arrangements for mangles and wringers.-The laminated spring 2 is housed in a arched bar 5 of channel section which can swivel about the pressure screw 3. The arched bar bears on the ends of levers 6 pivoted to a cross-bar 7 which transmits the pressure to the bearings of the upper roller. The other ends of these levers normally are engaged by a crossbar 12<c>, and are kept horizontal thereby, and the cross-bar is connected to levers 8, the ends of which are joined by guard rods 9. If either guard rod is moved towards the roller, the cross-bar 12<c> is freed from the levers 6, which consequently tilt under the pressure of the spring 2 transmitted through the arched bar 5; this member therefore swivels and releases the pressure from the rollers.

Title: Improvements in or relating to processes of treating tin-containing ores and metallurgical products
IPC: C22B25/02
Filed: 1926-08-05
Abstract: 256,634. Krupp Grusonwerk Akt.- Ges., F. Aug. 7, 1925, [Convention date]. Tin oxide and sulphide.- Tin-containing ores and metallurgical products are heated to volatilize the tin in the form of sulphide, solid sulphurcontaining materials such as pyrites being added if necessary to supply the requisite sulphur. The operation may be effected in a reverberatory furnace such as a rotary tube, in which case there is added some reducing agent such as fuel to avoid oxidation; or a blast furnace may be employed, when sufficient fuel will usually be present throughout. The furnace gases themselves may be oxidizing and need not contain sulphur, and' in these circumstances the tin sulphide volatilized from the material is converted to, and recovered as, oxide. If, however, the furnace gases are neutral the tin sulphide is recovered as such.

Title: Vibrating roller
IPC: E01C19/28
Filed: 1974-05-03
Abstract: 1449370 Vibrators I L MARTINEZ 3 May 1974 [3 May 1973] 19519/74 Heading F2X A vibrating roller is provided with a shaft and an eccentric mass, the mass comprising at least one body idle relative to the shaft and at least one body rigid with the shaft, which bodies are so arranged that upon reversing the direction of rotation of the shaft, the respective centres of gravity of the bodies take distinct positions, the centrifugal forces generated thus attaining predetermined levels in each case. The roller is also provided with means for damping mechanical shock occurring upon reversing the direction of rotation of the shaft. In one embodiment (Figs. 2 and 4) employing hydraulic damping, an outer eccentric body 2 is fixed to a driving shaft 1 by means of keys 10 and houses an inner eccentric body 3. The inner body 3 rotates in an idle manner about the shaft 1 and takes predetermined positions depending upon the direction of rotation of shaft 1, when a projection 7 it carries abuts against a projection 5 on the outer body 2. Gaps 8 are formed between the bodies 2, 3 through which a damping liquid flows upon reversing the direction of rotation. In a second embodiment (Fig. 6) employing mechanical damping, an idling inner body 12 is mounted on the driving shaft 1 between two outer bodies 11 fixed to the shaft 1 by means of keys 10. Projections (13) (Figs. 5 and 7, not shown) rigid with the bodies 11 engage one of two diametrically opposite shoulders on the body 12 depending on the direction of rotation of the shaft 1. Shoes 14 positioned between the bodies 11, 12 are urged by springs 15 to provide the frictional force necessary for the driving engagement when the shaft 1 is rotated counterclockwise by making the bodies 11, 12 rigid with one another up to a predetermined speed, with a subsequent sliding therebetween when the centrifugal force generated in the idly rotating body 12 on the shaft 1 is higher than the frictional force, thus avoiding violent shocks.

Cam-, lever-, and spring - actuated pumps; disconnecting actuating- mechanism; stroke, varying; timing-devices. -In a fuel pump, the plunger 13 is actuated on the delivery stroke by a spring 10 and on the suction stroke by a lever 8, a lever 16 pivoted on the lever 8, and a rocker 20 on the lever 16 operated by a cam 3. The stroke may be varied by means of an adjustable stop 14 engaging the lever 8, and also by a governor-controlled wedge 18 sliding on another wedge 21 and engaging a rod 17 on which the lever 16 abuts. The wedge 21 may be adjusted vertically by a screw 22. The lever 8 is pivoted on a lever 5 which may be adjusted on its pivot 4 by screws 6 to vary the time of injection. Delivery may be stopped by means of a cam 24 which can be turned to hold the rocker 20 out of contact with the cam 3. The time of injection of several pumps may be simultaneously adjusted by driving the cam-shaft 2 by means of oblique gears 33, 34, and making the shafts 35 axially adjustable by screws 36 and lever 38 respectively. The wedges 18 may be adjusted by the governor rod 26 through springs.
