Title: Improvements in apparatus for spraying printed sheets in printing presses
IPC: B41F23/06
Filed: 1936-08-10
Abstract: 478,284. Fluid- - actuated valves. CHIESA, A. D. D., and FROEHLICH, L. P. Aug. 10, 1936, No. 22005. Convention date, March 11. [Class 135] [Also in Group XVI] Admission and exhaust of compressed air from a cylinder 30 controlling the valves 19, 21 of a device 17 for spraying printed sheets, is effected by a valve structure 37, Fig. 6, to which is connected a pipe 28 leading to the cylinder 30 and another pipe 27b leading to the compressed-air supply. The admission-valve 38 is pressed on to its seat by a spring 39 and has a hollow stem 38a forming a passageway to the exhaust port 42. A valve 40 controlling the exhaust passage has a reduced extension 40a which passes through the valve 38 and abuts against a spring 43 in an extending part integral with the valve 38. The stem 40b of the valve 40 abuts against a rod 44 which is moved axially at intervals by a member of the printing- machine so as to close the valve 40 and then open the valve 38. Admission of compressed air to the cylinder 30 causes a piston 29 and a tube 32 fixed thereto to move upwardly, the tube 32 carrying a stop 34 engaging a lever 22 so as to operate the air valve 21. The stem of the needle-valve 19 controlling the supply of liquid to the sprayer 17 passes through the tube 32 and piston 29 and is loaded by a spring 36 pressing against an adjustable stop 19a thereon, the stop being engaged by the piston 29 to open the valve 19 shortly after the valve 21 has been opened.

In use the arm 5, 6 is moved so that the element 8 rocks and slides along the edge 11, when half the ellipse may be drawn.
Patent GB-392136-A (GB)
Title: A process and apparatus for obtaining synchronised screening and de-screening of picture and sound in the production of sound films
IPC: B22D27/11
Filed: 1931-08-04
Abstract: 392,136. Associated sound and picture recording-apparatus. KLANGFILM GES., 4, Askanischer Platz, Berlin. Aug. 4, 1931, No. 22111,. Convention date, Aug. 2, 1930. Void [Published under Sect. 91 of the Acts]. [Class 40 (ii).] Apparatus for recording combined sounds and pictures is provided with means whereby, at the commencement or end of a recording, the building up or cutting off of the picture record and the increasing or fading of the sound record can be effected synchronously. As shown in Fig. 1, applied to combined picture and variable-density sound-recording apparatus, the picture camera 1 and sound camera 2 are provided with synchronous motors 3, 4, whose stators are fed from the supply wiring while their rotors are interconnected. Normally these motors, which are provided in addition to the driving motors of the cameras, are stationary, but cranks 5, 6 are provided on the motors 3, 4, respectively, so that if, for instance, crank 5 is turned through a certain angle, then the motor 4 with the crank 6 is automatically turned through the same angle due to the electrical connection of the motors. This rotational movement operates the screening means which can thus be controlled either from the picture camera by the crank 5 or from the sound camera by the crank 6. Fig. 2 illustrates the screening means of the picture camera. When the crank 5 is rotated, a gear wheel 11 transmits the drive to a gear 12 in such a way that a member 13 abuts against the end of a crank 10 to transmit the rotational movement to a cup-shaped screening sector 9 which is adapted to move in front of the objective of the picture projector. The screening means for the sound camera comprises a screen 15 carried on a screen holder 14 which is moved by rotation of a cam disc. The screen 15 may be shaped so that the recording light beam is screened gradually across its width in any desired manner. When applied with soundrecording means of the variable width, electromagnetic, or groove record types, the screening or descreening means is used to control the output of the amplifier which supplies the varying currents to the recording head. For this purpose, rotation of the motor 4 is caused to adjust a regulating resistance inserted in the amplifier output to the recording head. The synchronous motors 3, 4 may be utilized to control an indicating device to enable the operator to control the sound record in synchronism with the cutting off or commencement of the picture recording.

Abstract: 1314625 Permanent waving and uncurling EUGENE-GALLIA 19 April 1971 [5 June 1970 2 Nov 1970] 22294/71 Heading DIP Human hair is permanently waved, curled or uncurled using a composition comprising thioglycollic or thiolactic acid or an alkali metal or ammonium salt thereof, and an alkalinizing agent in the form of the carbonate of an amino acid alkali metal salt, the composition being substantially devoid of free ammonia. The aminoacid alkali metal salt carbonate may be prepared separately, or formed during the preparation of the composition by adding lithium, sodium or potassium carbonate to an amino acid selected from: glysine, lysine, methionine, tyrosine, glutamic acid, leucine, valine, or alanine, either in optical isomeric or racemic form. Either the carbonate or the amino acid may be in excess, or the quantities may be stoichiometric. The composition may include a base, such as morpholine, monoethanolamine or triethanolamine, to increase the hair permeability, lauryl pyridinium chloride or cetyl-trimethyl-ammonium bromide to increase the curling rate of the hair, and oxyethyleneated lanoline to have a softening effect. Other additives include sequestering, and opaquing agents, and perfume. De-mineralised water may be used to make up an aqueous solution for use in permanent waving. For uncurling hair, the solution is applied as a viscous emulsion containing cetyl alcohol emulsified with oxyethylenated cetyl alcohol. The action of the composition may be accelerated by heat.

Title: Improvements in or relating to television receivers
Inventor: MONTAGUE BRYAN WILLIAM ST LEGE
IPC: H04N3/20
Filed: 1951-09-24
Abstract: 740,613. Cathode-ray tube circuits. MULLARD RADIO VALVE CO., Ltd. July 29, 1952 [Sept. 24, 1951], No. 22324/51. Class 40 (7). Relates to a television receiver having permanent magnet focusing of the cathode-ray tube in which pulses from the line and frame timebases are applied respectively to diodes 2 and 5 whose load resistors 3, 4 and 6 are connected in series in the grid circuit of the tube, the cathode of the tube being held at a potential higher than that at the top of potentiometer 3 so that under normal operating conditions a suitable bias is applied to the grid of the tube by the potentiometer slider but if one or both of the timebase circuits fail the voltage across the resistor chain 3, 4, 6 is reduced and the beam current is cut off, thereby preventing damage to the screen. If the receiver is then switched off, the H.T. supply falls rapidly leaving the tube without bias and so allowing the stored energy of the E.H.T. supply to discharge into a stationary focused spot and so damage the screen and according to the present invention this is prevented by connecting the lower end of the resistor chain to earth through a diode 7 whose anode is also connected to H.T.+ through a resistor 8 shunted by a capacitor 9 so that under normal operating conditions the diode is conductive and capacitor 9 is charged almost to the full H.T. voltage but on switching off, the stored charge on capacitor 9 drives the anode of diode 7 negative to earth and biases the tube off, the time constant of 8 and 9 being such that this condition is maintained until the tube cathode ceases to emit electrons. The diode 7 may be replaced by a contact rectifier or by an unused section of another valve, e.g. the suppressor grid of an R.F. pentode.

Abstract: 692,471. Testing physical qualities of material. CADLING, L. O. T. Aug. 25, 1948 [Sept. 5, 1947], No. 22395/48. Class 106 (ii). Apparatus for testing soil comprises a core rotatably mounted in a tube and having at one end a bit formed with radial vanes, means secured to the upper end of the core connected elastically to a rotatable member co-axial with and adjacent to the upper end of the tube and means for indicating angular displacement of the core resulting from rotation of the rotatable member. A rod 3, built up from sections, is protected by a tube 4, also in sections, which are joined by collars 6, and carries at its lower end a bit 1 having vanes 2. The rod 3 and tube 4 are driven into the ground to the depth at which a test is to be made and then the bit 1 is projected to the position shown into soil undisturbed by the tube 4. A torque is then applied to the rod 3 by a handle 13, rotatable upon a collar 9 secured to the tube 4 and connected by springs 14 to a bar 8 secured to the rod 3. When the bar 8 commences to move due to shearing of the soil, the handle 13 is held stationary and the time for the bar 8 to move through a predetermined arc is observed. This is stated to be a measure of the property of the soil under test. A calibrated disc 10 mounted on the collar 9 enables the angular displacement of the rod 3 and bit 1 to be observed. The rod 1 is guided by a plug 5 in the tube 4 and the rod 3 is guided by internal projections 7 of the collars 6 and by a similar projection 12 of the collar 9. The tube 4 may be extended so as to protect the bit as it is driven into the ground. The Specification as open to inspection under Sect. 91, states that electrical strain gauges may be secured to the vanes of the bit. This subject-matter does not appear in the Specification as accepted.
