Title: Improvements in or relating to the manufacture of cinematograph films with sound records
IPC: G11B7/00
Filed: 1930-12-24
Abstract: 369,948. Recording sound optically. BAKER, T. T., The Hut, Hatch End, Middlesex, and SPICERS, Ltd., 19, New Bridge Street, London. Dec. 24, 1930, Nos. 38961/30 and 15878/31. [Class 40 (ii).] Relates to the optical recording of sound by the variable intensity of light method wherein a screen is placed across the light path from a sound-sensitive light source to the sound record film, the opacity of the screen being so varied along its length that compensation is effected for irregularities in the characteristics of the parts of the recording apparatus, e.g. in the microphone, the amplifier, the light source, or the light-sensitive film emulsion. As shown in Fig. 1, current from a microphone 7 is amplified by a valve 8 and conducted to a light source 9 which may be a potassium vapour lamp or a gas discharge lamp having a rectangular light-emitting cathode. Light from the source 9 is focused upon the sound record track of a film 22 and in the path of the light beam is interposed a neutral grey wedge 17 provided with a micrometer adjustment 18. In Fig. 4, AC shows the density curve of an ordinary neutral grey wedge and to compensate for the curvature of the upper part of the characteristic curve of the light source 9, the opacity of the wedge is varied to conform to the curve ABD. Fig. 5 shows the characteristic curve of an emulsion which gives too dense high lights, and Fig. 6 shows how the opacity of the wedge may be varied to compensate for this undesirable characteristic. AB is the normal curve for the wedge, ACB is the curve of a wedge modified to counteract the undesirable characteristic of the emulsion, while ACD is the curve for a wedge modified to compensate both for the emulsion curve of Fig. 5 and the light-source curve of Fig. 3.

Abstract: 806,993. Quenching. GLEASON WORKS. Dec. 21, 1956 [Dec. 22, 1955], No. 39063/56. Class 72 Ring shaped articles such as ring gears are relieved of stresses and distortion resulting from forging and machining, by heating to about 1550‹F., clamping between dies and flexing. As shown in Fig. 1, a bevel gear ring 20 having teeth 22 is heated to about 1550‹F., clamped between four ring-shaped dies 23, 24, 25 and 26 and flexed torroidally, by vertical displacement of the dies 24 and 25, about the neutral circle 27, first in the direction shown by arrows 28 on Fig. 2 and then in the opposite direction as shown by arrows 29 on Fig. 3. According to whether surface hardening or complete hardening is required the part to be treated may or may not have been previously carburized. In an example, a ring gear of carburized steel was heated in 1550‹F., flexed through two cycles by moving dies 24 and 25 vertically to 0.01 inches either side of their neutral position and quenching the gear for 10 seconds in mineral oil at 110-120‹F. whilst still between the dies, thereby lowering the temperature of the gear to 700‹F. The gear was then removed from the dies but retained in the quenching medium for a further 140 seconds, at the end of which time the temperature had fallen to 130‹F. A machine for the coninuous treatment of parts is described in detail.

An arc lamp or laser 1 with condenser lens 2 uniformly illuminates coding mask 3 producing beams B1 to B7 imaged by lens 4 in channel 14 of capillary tube 13, in which cells 12 flow in single file. Fluorescent output from each cell is imaged on photo-multiplier 17, with filter 16 blocking the exciting wavelengths or alternatively photomultiplier 17 being perpendicular to the exitation. The distance between B 1  & B2 is (#2 - #1) x the spacing factor, and (#3 - #2) x the spacing factor for B 2  and B 3  and so on. The delays of delay line 19 correspond to these spacings, so that the pulses due to beams B 1 -B 7  reach adder 20 simultaneously Processor 28 classifies the number of output signals within certain amplitude ranges. These are tabulated in registers 29, 30, 31. In the embodiment of Fig. 5 (not shown) amplifier 18 is followed by filter (32) blocking the high frequency noise and passing the low frequency signal pulses to integrator (33) feeding processor 28. Multiple responses from the transducers may be produced by exiting the cells concurrently or successively with a plurality of wavelengths.

Title: Method for the conversation of living organs
IPC: A01N1/00
Filed: 1972-08-31
Abstract: 1398565 Conservation of living organs R K DOERIG 31 Aug 1972 [2 Sept 1971 24 March 1972] 40484/72 Heading A2D In a method for the conservation of living organs by perfusion wth ai cooled medium: enriched with a respiratory gas, the perfusion is subjected to automatic regulation of flow rate in response to the flow resistance in the organ, and a perfusing pump is used which is driven by a substance which is a gas at room temperature and atmospheric pressure. The substance may be a respiratory gas or carbon dioxide derived from dry-ice. The method may be carried out in an apparatus comprising a thermo-insulated vessel which contains an organ compartment and a pump compartment, the latter compartment being provided with perfusate inflow and outflow valves, gas inlet and perfusion-pressure or perfusion-volume monitored gas-outlet valve. A suitable apparatus is shown in Fig 3, and comprises a pump compartment 3, organ compartment 5 and dry ice-containing compartment 31, the latter being provided to supply CO 2  to drive the pump, enrich the perfusable and also cool the perfusate. In operation, CO 2  from compartment 31 passes via tube 13 to gas inlet 7 of a perfusion pump and produces a pressure on the elastic membrane 23 if gas inlet valve 9 is closed. Perfusate is thus forced via outflow valve 6 to the organ 15. Perfusate flowing from vein 18 raises the perfusate level in organ compartment 4 and forces air out of valve 36. When the desired pressure is reached in compartment 3, the prestressed membrane 10 lifts from valve fitting 12 and CO 2  is vented through opening 11 and outlet 8. The membrane 23 then contracts and perfusate flows from compartment 4 via inflow valve 5 into compartment 3. The level of perfusate in 4 falls back to the dashed line mark. Air or if the dashed connection with outlet 8 is made, CO 2 , is sucked in via tube 37, thus inriching the perfusate. Membrane 10 returns to its original position on reduction of the pressure in compartment 3 to its initial value, and a new cycle of operation commences. Instead of CO 2 , air or another respiratory gas may be used as the pump-driving and perfusate-enriching gas. In this instance, the apparatus need not include a dry-ice-containing compartment (Figs 1 and 2, not shown). The monitored gas outlet valve may use magnetic elements as regulating means (Fig 4, not shown).
