Patent GB-724801-A (GB)
Title: Improvements in or relating to protective oxygen respirators providing circulation of the respiration air
IPC: A62B9/02
Filed: 1953-02-23
Abstract: 724,801. Respiratory appliances. AUERGES. AKT.-GES. Feb. 23, 1953 [Feb. 23, 1952], No. 5033/53. Class 81 (2). A closed circuit respirator has a scavenging port opened by the exhalation valve and means for ensuring that the system contains a high proportion of oxygen on being taken into use. The inhalation and exhalation valves are mounted in a unit comprising a casing 4, Fig. 3, divided into two compartments by a partition 5. Air from the breathing bag is received through a connection 15 and passes to the mask through the inhalation valve 14. Air from the mask enters through a connection 2 and passes through exhalation valve 32 and pipe 8 to the carbon dioxide absorber and back to the breathing bag. On each occasion that the valve member 32 is raised it also opens a tube 10 leading to atmosphere through a restricted orifice 12, so that a small proportion of the contained air is expelled at each exhalation, thereby reducing the proportion of nitrogen retained. The main oxygen control valve, comprising a seating 44, Fig. 4, and plunger 46 is actuated through a connection 50 by a diaphragm 40 through the middle of which is a passage 52 restricted by a choke 54. The chamber 55 surrounding the latter is closed by a valve 58, 59 which is opened by inward movement of a second diaphragm 61. When oxygen is first turned on, it enters the control valve through duct 42 and, owing to the presence of choke 54, it causes a temporary excess pressure on the lower side of diaphragm 40 which opens the main valve 46 and allows a flow of oxygen into the system until the pressures on the two sides of the diaphragm are equalised, thus ensuring that a high proportion of oxygen exists before breathing commences. In order that there may be a minimum of stagnant air in the breathing bag at this time, a light spring is provided to maintain the bag in the collapsed condition when out of use. Oxygen from the control valve passes through a tube 21 to a connection 20, Fig. 3, adjacent to the inhalation valve and, at each inhalation, the reduction in pressure in the chamber 13 is communicated through port 16 and pipe 17, Fig. 4, to cause inward movement of the diaphragm 61 and venting of the space 55. This disturbs the balance of pressure on the two sides of diaphragm 40 and the main valve 46 is accordingly opened to admit a further supply of oxygen.
Patent GB-634189-A (GB)
Title: Improvements in and relating to the manufacture of silver and bismuth nitrates
IPC: C01G29/00
Filed: 1947-02-21
Abstract: <PICT:0634189/III/1> Silver or bismuth nitrate is produced by coating the surface of metallic silver or bismuth, confined in an atmosphere of oxygen gas at substantially atmospheric pressure, with a thin film of nitric acid which is continuously renewed, any nitrogen oxides which may be produced being reconverted to acid, and collecting the nitrate solution so formed outside the reaction zone.  As shown, silver or bismuth is contained in a tower 1 which is replenished from a hopper 4.  Oxygen and nitric acid are supplied through pipes 12, 13 so as to form a spray of acid.  An observation window 29 and lamp 30 are indicated, and the tower is heated, say to 65 DEG  C., by a water jacket 24 provided with a condenser 28.  The nitrate solution formed passes through mesh 19 to vessel 17.  The oxygen supply is preferably adjusted so that a bubble every few seconds escapes through the water in vessel 21.

Title: An improved method of and apparatus for producing musical sounds
IPC: G11B11/00
Filed: 1934-02-16
Abstract: 428,322. Producing musical sounds and artificial sound-records. WIENECKE, B., 73, Honowerstrasse, Mahlsdorf, Berlin. Feb. 16, 1934, No. 5134. Convention date, March 6, 1933. [Class 40 (ii)] Relates to the production of so-called synthetic musical sounds by using artificial representations of sound oscillations by means of which a reproducible photographic record may be made, or which can be used directly for the production of sound by photo-electric apparatus. According to the invention, use is made of such a representation, (referred to in the Specification as a "basic shape"), which is so constructed that its form may be rapidly changed in order that the " tonecolour " of the sound may be varied as desired. The basic shape may consist of an elastic band 1, Fig. 2, the form of which may be changed at will by means of a keyboard 5 and pins 4 acting on the band. Means are provided for giving good photographic contrast on opposite sides of the band, e.g. by using a white background and suspending strips of dark material from the band. An alternative construction of the basic shape, Fig. 3, comprises a series of narrow bars 1, closely adjacent to each other, and coloured black and white as shown. By means of keys 2, the boundary line between the contrasting colours may be given any desired shape, for example as shown at 56, in Fig. 6. This Figure shows an apparatus whereby sound may be produced directly by scanning the basic shape 56 by means of a beam of light, which is reflected from the device 56 on to a photo-electric cell 58, connected through an amplifier 59 to a loud-speaker 60. The scanning beam is produced by a lamp 53 enclosed in a rapidly rotating slotted drum 51. To regulate the intensity of the sound, exchangeable light filters 84 may be provided ; a shutter 82 is arranged as shown, to cut off the light when desired. Fig. 1 shows an apparatus for producing a record on a film 5 by projecting on to the film, in continuous succession, images of the basic shape 1. The latter may be a variable structure such as shown in Figs. 2 or 3, or may itself be an image of such a structure, produced by optical projection on a suitable screen. When a projected image is thus employed, it may be distorted in various ways. A rotary disc 2 having an exposure slot 3 is arranged between the shape 1 and an objective 4. The disc 2 and the film 5 are driven at suitably related speeds by a motor 6, the drive of the disc being effected through a variable speed gear 7, 8. The device 1 is mounted on a spindle 17<1>, the position of which can be adjusted by means of a handle 17 so that the length of the image projected on the film may be changed by fore-shortening. Adjustment of the spindle 17<1> effects, through a cam 16, a corresponding adjustment of the variable speed gear 7, 8, thus suiting the speed of the film 5 to the length of each of the images projected thereon. By this means variations may be made in the frequency of the recorded " synthetic " sound.
