Title: Optical reader correlation circuit
IPC: G06K7/10
Filed: 1975-08-08
Abstract: 1515386 Data reader E-SYSTEMS INC 8 Aug 1975 [20 Nov 1974] 33195/75 Heading G4M A reader for bar coded data, e.g. on letters, has three spaced sensors (95, 97, 99) past which the data is moved. The sensors produce time displaced signals and the centre signal (B) is amplified twice the amount of the other two signals. The signals from the outer sensors are added together and subtracted from the amplified signal from the centre sensor. The resulting signal clearly indicates the edges of the bar code and will indicate an error if for instance bar 93 should have been a space and due to dirt or smudging is indistinguishable from the bars on either side. The reader has an image intensifier tube 10 on which an image of the bar code is produced by a lens 14. Electrons from the photocathode 36 of the tube are deflected by coils 38 to appear at a desired position on a phosphor screen 40. The phosphor screen is coupled by a series of fibre optic strands 18 to a matrix of light responsive sensors in a signal conditioner 54. This supplies signals to a logic circuit 58 which derives signals for the deflection coils to centre any off-centre image on the phosphor screen. The matrix of sensors feeds signals to a circuit containing an encoder which generates a digital code identifying the topmost zone of sensors through which the lower portion of a bar code passes. This code is fed to a read only memory which generates signals which are converted to deflection signals to centre the image in the phosphor screen. The circuit is arranged to alter the horizontal deflection signals after the first pass of the bar code so that the code passes a second time past the sensors.

Patent GB-311297-A (GB)
Title: Ironing machine
IPC: D06F71/32
Filed: 1927-12-09
Abstract: 311,297. Reeps, C. O. Dec. 9, 1927. Ironing-presses.-An ironing- machine, of the type wherein two ironing members are relatively movable to each other to apply pressures to the article being ironed, is provided with means for forcing air through the pressing member and article, and subsequently forcing air therethrough in the opposite direction to cool the article. Upon starting a motor 43, Fig. 2, a rotary motion is given to a disc 30 to reciprocate a. link 29 thereby pressing a head 18 upon a buck 17. The head 18 is guided by arcuate slots 15 so that it is rocked upon the buck 17. The head 18 has a line contact with the article and consequently exerts greater pressure on it than otherwise would be the case. The buck is heated by steam flowing in pipes 71, Fig. 7, connected to a live steam chamber 69. The steam flows through pipes 71 into pipes 67, thence to an exhaust chamber 70 and outlet 77. A motor 46, Fig. 2, is started after the operation has placed an article to be ironed on the buck. The motor actuates a fan 48 to blow air through the buck. During this operation a button 50<1> of the switch will be in its outermost position. The air forced into the buck is pre-heated by the steam pipes and emerges through perforations 80, Fig. 8, so as to augment the drying of the article and also to force the article away from the perforations and give it a smoother press. When the ironing is finished, the extension 51<1> connected to a rod 25 forces the switch button 50<1> downwards breaking the circuit of the motor 46 and reversing it. The fan 48 then functions as suction medium to draw air downwards into the buck 17, cooling and drying the article.

Abstract: 604,104. Aircraft gun turrets. NASH, A. F. Dec. 3, 1935, No. 33466. [Class 92 (i)] An aircraft turret capable of being raised and lowered is guided during such movements by a straight line link motion mechanism. This mechanism may consist of upper levers 11, 16, and lower levers 19, 23, pivoted about fixed axis and joined as shown to the arms of levers 14, 21 pivoted to the turret. Similar mechanism is provided on the other side of the turret. The raising and lowering movements may be effective by two hydraulic rams 10, which are connected to the arms 11, the rams being controlled by movements of a handleaccessible to the gunner. The handle may serve to move a cam which moves a link which is connected by Bowden mechanism with the control valves of the rams 10. The link may be associated with a roller which cooperates with a cam surface rotating with the turret, whereby the turret may rise and fall as desired when it is made to rotate.

[Also in Groups XXVI and XXVII] An engine starter (see Group XXVII) is powered by a gas turbine 6 driven by a mixture of hot gases and compressed air in the case of Fig. 1, and hot gases and steam in Fig. 2. In Fig. 1, compressed air from a bottle 1 or from a cooled compressor enters an expansion chamber 14 through a metering aperture 15 and passes through a valve 24 into a pipe 5 to rotate the turbine at slow speed. By means of a primer 17 powder in a container 16 is then ignited and fires a cartridge bag 18, the gases acting on a piston 23 to open a valve 25 so that air at high pressure passes into the pipe 5 and mixes with hot gases passing through apertures 22; the action of the valve closes the valve 24 through a trigger 29. When the powder in the bag 18 is all consumed, the valve 25 returns to its seat and the turbine stops. The valve 24 is reset by means of a handle 32. In Fig. 2, hot gases produced by firing a cartridge bag 36 pass through a port 40 into a chamber 39 so as to mix with a spray forced out of a nozzle 41 by the pressure of hot gases entering a water tank 33 through a pipe 38. The cartridge bag is such as to produce a reduced pressure initially.
