Filed: 1949-04-29
Abstract: 659,511. Mopping elements. GREENLEAF, N. B. April 29, 1949, No. 11517. Convention date, Dec. 21, 1948. [Class 19] A mopping element comprises a quadrangular block of sponge material, a sheet metal backing plate provided with screw-threaded attaching means and of an area less than the area of the upper surface of the block mounted centrally on the upper surface and secured to the block to permit the block to be attached to a mop head by means of the screw-threaded attaching means. A strong fabric may be adhered over the backing plate to the sponge material exposed around the edge of the plate with the screw-threaded attaching means being exposed through the fabric and if desired the fabric backing piece may be extended over the forward edge of the sponge element compressing a quantity of the sponge in a fold of the material to form a bumper. Fig. 1 shows a form of the mopping element incorporating a fabric fold stiffening rib along its upward forward surface and having an exposed reinforcing backing plate; Fig. 2 shows an alternative form of mopping element with the fabric adhered over the backing plate to the sponge material and with the stiffening rib formed at the forward upper edge of the mop by the fabric fold. The mopping element is a longitudinal quadrangular block 1 of sponge material. Adhered to the upper surface 2 of the block is a sheet metal or other stiffening plate 3, the area of the plate being slightly less than the area of the upper sponge surface. Cellulose acetate is a suitable adhesive. Adhered over and to the plate 3 is a strong fabric 5 and the fabric is adhered to the sponge material exposed around the plate 3. The forward edge of the fabric is extended beyond and folded over the upper edge 7 of the block 1 with the fabric fold 8 ending and compressing the sponge material of the forward edge 7. Formed in the stiffening plate 3 in spaced relation are the orifices 9 to receive suitable screws carrying sheet metal threads to permit the mopping element to be movably secured to a mop head.

Title: Improvements in or relating to protection circuits for cathode ray tubes
Inventor: PRATT ALAN HERBERT
IPC: H04N3/20
Filed: 1952-05-08
Abstract: 731,679. Television. ELECTRIC & MUSICAL INDUSTRIES, Ltd. April 24, 1953 [May 8, 1952], No. 11603/52. Class 40 (3). In a cathode-ray tube television receiver in which an " economy " diode arrangement supplies an increment of voltage to the high-tension supply for the (line) deflecting circuit means sensitive to this increment is provided which reduces the energy of the cathode-ray tube beam in the vent of failure of the deflecting circuit. The invention is particularly concerned with television receivers in which the E.H.T. is derived from circuits separate from the scanning circuits. In one embodiment (Fig. 1), the normal operating bias applied to the cathode 4 of tube 1 is derived, via a potentiometer 13 in the anode circuit of a valve 15 which is so biased by means of potential dividers 17, 18 and 20, 21 that the valve conducts under normal operating conditions. In the event of failure of the (line scanning circuit 5 the increment of potential which the " economy " diode 11 supplies (effective across condenser 9) is reduced to zero bringing the grid of valve 15 to such a potential that conduction ceases and the resulting rise of potential at slider 12 of potentiometer 13 reduces or cuts-off the beam of tube 1. If the circuit generating the E.H.T. (e.g. separate oscillator) and the line scanning circuit are supplied from separate H.T. sources the junction of potentiometer 13 and resistor 17 should be connected to the H.T. source which supplies the E.H.T. generating circuit to ensure that the beam of tube 1 is cut-off or reduced in intensity in the event of failure of the H.T. supply to the deflecting circuit but not of the H.T. supply to the E.H.T. circuit. In a further arrangement (Fig. 2) suitable for use in circuits in which-'the picture signals are supplied to the cathode of tube 1 the usual operating bias (applied to control electrode 3 of tube 1) is derived from the potential divider chain 24, 13, 25 so that in the event of failure of the (line) scanning circuit the drop of potential across condenser 9 is effective to reduce the bias on electrode 3 and thus cut-off or reduce the intensity of the beam.

Title: Roller felting machine
IPC: A42C1/02
Filed: 1946-04-16
Abstract: 610,783. Felt. CASSE, M. April 16, 1946, No. 11693. Convention date, April 14, 1944. [Class 42(ii)] In a roller felting machine having at least two groups of rollers, all the rollers of at least one group are given a circumferential oscillation, superimposed on their normal continuous rotation, as well as an axial reciprocation, both movements being derived from the same eccentric shaft. In a machine in which both movements are in phase (Fig. 1), the coupling disc 1 of each of the rollers is keyed to a rod 3 having a guide 4 slidable axially in a sleeve 5 integral with a pinion 10 which meshes with a worm which gives it a continuous rotation. A screw 9 on the end of the guide 4 has teeth engaging grooves in the walls of an internal cavity 6 in the sleeve 5. The rod 3 terminates in a spherical head 11 engaged in a corresponding cavity in a connecting rod head 13 mounted on an eccentric 15 on the shaft 16, which is driven by pulley 17. The reciprocating axial movements are converted by the movement of the screw 8 into oscillating rotary movements which are superimposed on the continuous rotation of the rollers. In an arrangnement in which the axial and rotary oscillations are 90 degrees out of phase (Fig. 3) the guide 4 engages the sleeve 5 by teeth and grooves 20 and 21. The worm 22 driving the pinion 10 is arranged for axial movement on the shaft 24, and is enclosed in and abutted at its ends by a sliding block 25. The latter carries a rack having oblique teeth 30 engaging grooves 31 cut in the face of a block 33, which is reciprocated by a rod 35 connected to the eccentric 15, which, as previously, also gives the rod 3 an axial oscillation. The oscillating rotary movement is derived from the axial reciprocation of the worm 22 by the blocks 25 and 33.

Abstract: 364,471. Type-bar-making machines. INTERTYPE CORPORATION, 360, Furman Street, Brooklyn, New York, U.S.A. April 23, 1931, No. 12071. Convention date, Sept. 24, 1930. [Class 100 (iii).] Moulds.-In moulds in which the cap-plate is raised, in order to facilitate ejection of the type-bar, the cap-plate is provided with projections, which are adapted to raise the liners together with the type-bar held between them. The liners 9 are held to the base 6 of the mould by bolts 10, which permit a limited vertical movement. The liners are preferably formed with grooves 11, or with ribs, which anchor the type-bar to them. The cap-plate 5 is provided with shouldered projections 4, which are so formed that, as the cap-plate rises, it moves away from the liners, and lifts the liners away from the base. Both faces of the type-bar are thereby separated from the. mould, as shown in Fig. 7. The right-hand liner is held by springs against ridges on the cap-plate and base, in order to permit of expansion of the mould when hot.

Title: Improvements in or relating to fluid-pressure governors for fuel injection pumps

Abstract: 1,069,211. Fluid-pressure servomotor systems. MONO-CAM Ltd. March 26, 1964 [March 27, 1963], No. 12129/63. Heading G3P. The parts of a governor for a fuel injection pump are in the position shown when the engine is stationary; upon starting the engine the governor gear-pump 5 supplies pressure through a restriction 7 to a chamber 3 and moves a spring-urged piston 2 and control rod 1 to the right to increase the fuel supply to the engine. The pump is also connected to a chamber 9 so that as the engine speed increases the pressures in chambers 3, 9 increase until a spring-loaded control-valve in the chamber 9 is moved rightwardly to open a passage 8, 12 from chamber 3 to the pump inlet; the engine speed at which this occurs is determined by a lever 15 that sets the loading spring of valve 11. In a modification, a by-pass across the pump is controlled by a spring-loaded valve, the opening of which is adjustable and the spring-loading of which is greater than that of piston 2 but less than that of valve 11. The lever 15 may be dispensed with and the by-pass valve adjusted to determine the governed speed. The by-pass valve may be comprised by a spring-loaded ball-valve 26 in series with an adjustable throttle 30. These two embodiments, which are intended for a greater range of engine speed than that of Fig. 1, operate with a small pressure change in pump output passage 6 over the engine speed range.
