Title: Improvements in timing and alarm apparatus
IPC: G04F3/02
Filed: 1921-04-09
Abstract: 183,196. Anger, J. E. April 9, 1921. Alarms and alarm mechanism.-A time-alarm in which the clockwork driving means are engaged by setting an indicator, is set to run for a definite length of time, at the expiration of which an alarm is sounded. As shown in Fig. 2, the indicator 2 mounted on a spindle 4 which carries a toothed sector 5, is set by pulling it outwards and turning it over a dial until it comes opposite the required indication and then pushing it inwards. Alternatively a free-wheel clutch may be employed in order that the indicator may be freed from the control during the setting operation. This operation increases the tension of the driving spring 6 mounted on the spindle 4 or other suitable spindle and engages the sector 5 with a pinion 7 on a spindle 8 of the clockwork. The pinion 9 of a ratchet-wheel 10 of an alarm 11 is so located that on the expiration of the time period for which the indicator has been set, the sector 5 leaves the pinion 7 and being free from the clockwork control, it engages with the pinion 9 and actuates the alarm. In a modification, the toothed-sector is dispensed with and a toothed-rack 17, Fig. 7 is employed, which during the setting operation is pulled outwards. This rack is provided with teeth wide enough to mesh simultaneously with two toothed wheels, one for winding the driving spring and the other forming the first wheel of the clockwork train, which during the setting operation is freed from the rack by means of a free-wheel clutch. During operation, the rack 17 moves inwards under the control of the clockwork, but when the cut-away part 33 of the rack arrives under the first wheel of the clockwork train, the rack is freed from the control, but continues to move under the action of the driving spring.

Title: Cathode-ray tube apparatus
Inventor: NEALE DENIS MANKTELOW
IPC: H04N5/202
Filed: 1953-04-17
Abstract: 736,899. Television. ILFORD, Ltd. April 15, 1954 [April 17, 1953], No. 10599/53. Class 40 (3). [Also in Group XL (c)] In cathode-ray tube apparatus, such as, for example, a flying spot scanner, a desired light output modulation control voltage characteristic of the tube 1 is obtained by means of an arrangement including a photo-cell 5 which feeds back a voltage ef proportional to the light output to the modulation control circuit. This circuit comprises a differential amplifier 15, 16 to one input grid 19 of which is applied a modulation voltage ec and to the other input grid of which is applied the feed-back voltage ef. A voltage ea proportional to the difference of the inputs appears in the anode circuit of amplifier 15 and is applied through D.C. amplifier 22 to the control grid 14 of the cathode-ray tube. The polarity of the feedback voltage ef is arranged such that a fall in light output causes a compensating increase in beam current. The circuit tends, therefore, to reduce any difference between ec and ef and by utilizing a high value of anode resistor 18, or a large gain in D.C. amplifier 22, the difference between ef and ec can be made negligibly small. Where the feed-back voltage ef is a linear function of the light flux incident on the photocell 5, the circuit operates to produce a linear relationship between the light output of the tube and modulation voltage ec. To produce a non- linear relationship there is inserted in the feed-back path between photo-cell 5 and differential amplifier 15, 16 a non-linear circuit element having a law corresponding to the inverse of the desired relationship. If it is desired to vary the electron beam current over a scanned raster to compensate for deficiencies in an optical system projecting image 3 this may be effected by placing a graduated filter or a replica of the optical system in the light path in front of the photo-cell.

Title: Improvements in or relating to servo assisted means for controlling the movement of road and like vehicles
Filed: 1941-10-02
Abstract: 575,314. Valves. CLAYTON DEWANDRE CO., Ltd., and EDGE, S. H. Oct. 2, 1941, No. 10856/42. Divided out of Complete Specification of 575,313. [Class 135] [Also in Group XXXI] A pneumatic control system for vehicles comprises for each side of the vehicle a single operating member 1 acting on valves 5, 4, 3 to control servo cylinders 10, 11, 12 in succession to disengage a clutch, control a gear drive and finally apply the brakes to stop or steer the vehicle. In the construction shown, the lever 1 is connected by a link 14 to the valve 5, and acts directly on the valve 3 and through a lug 40 on the valve 4, so as to connect the cylinders 10, 11, 12 either to the atmosphere or to a compressed air pipe 6. When the lever is in. position I, as shown, the gear and brake cylinders are connected to atmosphere through ports 34, 31, in their valves 4, 3, and the clutch cylinder 10 is connected to the air pipe 6 through the valve member 19 of its valve box 5, so that the clutch is held engaged. When the lever moves to position II, valve 19 is seated by its spring 21 to shut off the air supply and a valve sleeve 15 moves away from its valve 17, integral with valve 19, to allow air to exhaust from the clutch cylinder 10 through pipe 7, valve 17, sleeve 15 and ports 16, so that the clutch is disengaged. When the lever moves to position III, the lug 40 pushes in a plunger 30 to compress a spring 32 and move a piston 23 to the right to press a valve seating 25 against a double valve 26, 28, closing the exhaust valve 26 and opening the air valve 28 ; thus, air is admitted to the gear cylinder 11 through pipe 8 and a valve box 47, the valve 42 being open. A reduction gear is thus brought into operation to drive the vehicle at a lower speed than when the clutch is engaged'. When the lever moves to position IV it pushes in plunger 34 of valve box 3, closes the exhaust valve 36 and opens the air valve 38, so that air is admitted to pipe 9 and brake cylinder 12 and the brakes are applied. The gear drive is simultaneously disconnected by means of a cylinder 41 having a piston 43 acted upon by the pressure in pipe 9, so that this piston moves to the left and valve 42 is seated at 48 to shut off the air supply to gear cylinder 11 which is then exhausted through cylinder 41 and outlet 46.

Title: Dry transfer materials
Inventor: LYTHGOE ALAN LENNOX
IPC: B44C1/17
Filed: 1962-03-21
Abstract: 954,459. Transfers. LETRASET Ltd. March 5, 1963 [March 21, 1962], No. 10862/62. Heading B6C. A dry transfer material comprises a carrier sheet 1 having a polymer surface susceptible to solvent attack, indicia 2 in printing ink on said carrier sheet, said indicia being resistant to said solvent attack, and adhesive 3 covering said indicia and overlapping on to the sheet 1, the adhesive power of the adhesive 3 for the receiving surface being less in the said overlapping areas than in those areas registering with the indicia by reason of a modification of the adhesive in the overlapping areas resultant on solvent action of the surface of the sheet 1 in those areas. In one example, the sheet 1 comprises a transparent or translucent film of basically orientated polystyrene and the indicia 2 is applied by screen printing and includes a cellulose nitrate polymer, a plasticizer and a solvent. The adhesive 3 is pressure sensitive and may comprise an elastomer such as crepe rubber, a tackifying resin, an antioxidant, and a solvent such as a mixture of aromatic and aliphatic hydrocarbons which react with the sheet 1 on drying to produce a coarse matt finish in the overlapping areas as shown. A protective cover sheet comprising a non- migratory and strongly adherent release coating on a vegetable parchment sheet may be applied to the transfer assembly. To effect the transfer pressure is applied manually or mechanically on the sheet lover the required portions of the indicia a localized stretching of the sheet takes place. The solvent which attacks the sheet 1 may be applied before the adhesive. Printing surfaces.-The indicia may be transferred to offset lithographic plates as direct images. The plates may comprise a paper or metal support and the indicia may be applied with a typewriter or drawn with a greasy ink. Stencils.-The indicia may be transferred to a screen printing mesh by a curved &c. bar which frees the indicia without distortion on to the mesh surface. Stencil filler may be applied all over the transfer after the application of the transfer, and the transfer, which acts as a mask, then removed. The indicia may also be transferred directly to motion picture film, being sufficiently adhesive to withstand repeated projection and then enough to remain in focus. Furthermore, the indicia may contain ceramic pigments so that after transfer to glass or ceramic surfaces, the indicia may be fired into the surface. The indicia may also be used as an etch resist or may be a partially polymerized thermosetting resin which hardens fully on heating. In addition, the indicia may contain conductive pigments and the transfer used in printing circuits or resistors. In a further embodiment, aluminium is applied by vacuum techniques to the sheet 1 before the indicia is applied and in use the metal coating is transferred with the indicia.
