Title: Improvements in machines for cleaning, polishing, or scrubbing floors
IPC: A47L11/164
Filed: 1950-06-13
Abstract: 680,307. Floor-cleaning machines. HOLT, W. E. June 13, 1950, No. 14685/50. Class 138 (i). [Also in Group XXIV] A machine for cleaning, polishing or scrubbing floors comprises an electric motor, a horizontally arranged surfacing element rotatable about a vertical axis, a rotary drive member driven by the motor and having a plurality of symmetrically arranged projecting peripheral lugs, a bracket mounted. on the surfacing element and having recesses therein to receive the lugs, spring means on the underside of the bracket adjacent the recesses and arranged to resiliently engage the lugs when they are relatively moved through the corresponding recesses and angularly to positions: below the corresponding spring means and stop members on the underside of the bracket which limit the relative angular movement of the lugs and bracket. The machine, Fig. 2, comprises a vertical shaft 20 driven by the electric motor, a. drive member 21 having a flange 22 rotatably supported in the machine casing, and an annular brush, formed with a wooden base 31 provided with tufts 32, of wire, fibre or hair, which brush has connected thereto by screws 42 a bracket 40, Fig. 4. The driven member 21, which is rotated by a gear 25 on the shaft 20 through idler gears 27 and an internal gear ring 26 on the member 21, in known manner, is provided with three lugs 47, of substantially rectangular cross-section. The bracket 40, Fig. 4, is formed with three correspondingly shaped recesses 45 and three downwardly projecting stop members 43 each having a flat vertical face 43a, on its underside. Attached to the underside of the bracket are three flat springs 46 each secured at one end adjacent a recess 45 while its remaining portion is free and spaced away from and substantially parallel to the bracket and terminates adjacent to a stop member face 43a. To attach the brush and its bracket to the member 21 the lugs 47 are relatively moved through the recesses 45 and the brush and bracket are then turned angularly relative to the lugs in a direction counter to the normal direction of rotation of the brush, so that the lugs abut the faces 43a of the stop members and are positioned below and in contact with the springs 46. To detach the brush from the drive member the operation is reversed. With the above arrangement of drive connection, a positive drive is effected while the resilient support of the brush on the lugs 47 due to the springs 46 permits a limited movement of the brush vertically relative to the drive member 21, without disrupting the drive connection. The relative vertical movement between the parts prevents whipping or hopping of the brush on rough or uneven floor surfaces.

Title: Improvements in or relating to telegraphic pulse transmission systems
IPC: H04L25/40
Filed: 1970-03-26
Abstract: 1,267,876. Telegraphic error correction. SIEMENS A.G. 26 March, 1970 [31 March, 1969], No. 14707/70. Heading H4P.  In a telegraphic transmission system where errors are corrected by repetition, a start signal effecting retransmission is inhibited until receipt from a receiver of a call-up signal demanding the re-transmission. The start signal appears on lines StL or StT (and StK, not shown), when data from a tape reader, store or keyboard is available for retransmission on lines T, L or K, and is conducted to a logic circuit AL. Upon the arrival of a call-up signal on line AI the start signal is passed on line AT to an erase and control circuit Lo of a shift register D1 to D7. Upon the shift register becoming free, data in parallel form on line T, L or K enters the register via gates G1 to G5 and is transmitted in serial form via switch A5. The strapping shown with crosses may be inserted to enable transmission without the call-up signal.

Title: Improved method of and apparatus for disinfecting or fumigating
IPC: A01M1/20
Filed: 1933-03-21
Abstract: 418,200. Vaporizing liquid fumigants. ROBERTS, H. M., and HARRIS, C. G., Norton Hall, The Green, Norton-on-Tees, and IMPERIAL CHEMICAL INDUSTRIES, Ltd., Millbank, London. March 21, 1933, No. 14774/32. [Class 81 (i).] Fumigating apparatus, particularly for vaporizing liquid hydrocyanic acid, comprises a vessel fitted with an electrical heating element and with a cut-out comprising a fusible element (not forming part of the electric circuit) and a tiltable enclosed mercury switch. The arrangement is such that when the whole of the liquid has evaporated the consequent rise of temperature melts the fusible element and the electric circuit is broken. The vessel 1 is closed, until ready for use, by a cap 3 fitted with a safety valve 5. A heat-conducting strip 6 is arranged between the base of the vessel and the heater 8 and is formed with a stud 17 carrying a detachable cap 25 to which a plate 18 is secured by solder. The plate 18 is connected by a link 19 to a pivoted plate 14 carrying a mercury switch 12. A spring 20 causes rotation of the plate 14 when the plate 18 is released by fusion of the solder. A gauze cover 21 carried by a bayonet jointed ring 22 permits access to the compartment 2 so that the switch may be re-set by removing the cap 25 and fitting another cap carrying a new plate 18.

IPC: G03C1/76
Filed: 1930-05-14
Abstract: 341,822. Printing photographic images. KODAK, Ltd., Kingsway, London. -(Assignees of Capstaff, J. G. ; Kodak Park, Rochester, New York, U.S.A.) May 14, 1930, No. 14814. Convention date, May 17, 1929. Drawings to Specification. [Class 98 (ii).] A method of printing on photographic films and plates so that scratches on the surface of the emulsion will not affect the silver image comprises passing image-forming radiations, of a nature to be absorbed by the sensitive layer, through the support so that the image is formed in the layer in contact with the support and the printing light does not penetrate to the surface layer which thus forms a protective coating. This may be effected by printing with coloured, e.g. violet light, a dye absorbing this colour, e.g. yellow, being incorporated in the emulsion during printing. The process is applicable to the printing of kinematograph films and sound films.
Patent GB-1162758-A (GB)
Title: Improvements relating to P.C.M. Encoders
Inventor: MCNEILLY JOSEPH HOOD
IPC: H03M1/00
Filed: 1967-03-31
Abstract: 1,162,758. Analogue-to-digital converters. STANDARD TELEPHONES & CABLES Ltd. 31 March, 1967, No. 14854/67. Heading G4H. A P.C.M. encoder has means for generating locally a standard reference input signal, means for multiplexing the reference input with the normal input to the encoder, means for extracting from the coder output the coded representation of the reference signal and means for deriving from this a feedback signal controlling the response of the encoder. The normal speech input is applied through switch 11 to a resonant circuit 10 which rings with a starting amplitude proportional to the amplitude of the applied sample. The damped oscillating output is amplified at 12 and applied to a Schmitt trigger. Every oscillation above the operating threshold of the Schmitt trigger causes an output pulse, the number of pulses being representative of the input sample amplitude. The reference signal is applied to the encoder via switch 16 and the pulse groups relating to reference signal are gated to an adder 18 where they are added to a rising voltage ramp. The output of the adder is a succession of pulses of successively greater peak amplitude. The last causes a peak voltmeter 19 to produce a corresponding output which is inverted at 20 and added to the input of the Schmitt trigger 13 effectively to alter its operating level. By this means the encoder is automatically calibrated and adjusted to compensate for any variation of response.

Title: Process for continuously hydrogenating higher aldehydes in liquid phase
IPC: B01J19/24
Filed: 1962-04-18
Abstract: Saturated alcohols are continuously produced by the hydrogenation in liquid phase of olefinically unsaturated aldehydes having 6-13 carbon atoms by passing an aldehyde-containing feed through a plurality of multi-tube sprinkler type reactors in series, contacting the feed in each reactor with hydrogen in the presence of a hydrogenation catalyst in a fixed bed, recycling a portion of the product of each reactor to that reactor and recovering a substantially completely hydrogenated product.  Preferably the process is carried out at a temperature in the range 110-160 DEG  C., and a hydrogen pressure of 20-35 atms. using a nickel catalyst.  If desired the series of multi-tube reactors may be followed by a single-tube reactor.  An example is given of the production of 2-ethylhexyl alcohol by hydrogenation of a -ethyl-b -propyl acrolein.

Title: Improvements in or relating to the treating of materials by laser beam
IPC: H01L21/00
Filed: 1965-04-09
Abstract: <PICT:1067803/C6-C7/1> A workpiece 16 is treated in reactive atmosphere by means of a laser beam 12.  The laser 10 may be a ruby or a gas laser controlled by a pulser 60 and whose pulsed or continuous beam is focused by a lens 14.  Workpiece 16 which may be a ceramic or a metal such as tungsten is mounted on clamps 21 for universal adjustment in a chamber 18 containing a halogen such as iodine in a vessel 62 which is vapourized by a heating element 66. When the area of the workpiece impinged upon by the laser beam reaches a certain temperature it reacts with the vapour to form a volatile or soluble compound which leaves an etched spot, aperture, groove or slot.  The workpiece position is controlled by motors 22, 34, 36, 46, 48 in response to a programme which may be recorded on tape and which also controls the laser pulser 60.  The laser beam may also be deflected to scan the workpiece.  An iodine vapour gun may be used instead of the chamber 18 and other atmospheres such as oxygen may be used.  The invention may also be employed to deposit ceramics or metals such as tungsten on a substrate using a hydrogen atmosphere and tungsten hexaiodine vapour.  This process is used for producing microminiature arc lamps by depositing tungsten electrodes on quartz plates. Microminiature superconducting circuits are produced by depositing niobium-tin elements on a substrate.  Semi-conductor bodies of silicon, germanium or gallium arsenide, may have junctions or circuit paths deposited thereon by treatment in an atmosphere of arsenic or antimony. Spot or seam welds may be produced on ceramics or metals by vapour depositing joints at localized points.
