Title: Photographic camera with built-in flash socket
Inventor: BLATTNER DIETMAR
IPC: G03B7/16
Filed: 1969-02-10
Abstract: 1,262,355. Photographic apparatus. EASTMAN KODAK CO. Feb.10, 1969 [Feb. 9, 1968], No. 7105/69. Heading G2A. A photographic camera is provided with a shutter controlled in dependence on the prevailing exposure light by an electronic timing device having an R. C. -member, a rotatable lamp socket 12 for a flash cube 18, and a central control pin 16 in the socket movable against spring bias upon insertion of the flash cube into the socket, since this insertion depresses a collar 16a of the pin. Depression of the pin 16 closes a switch 17 to connect a fixed resistance (23) Fig. 3 (not shown) in parallel with a photo-resistance (21) of the R.C. -member to provide an exposure time appropriate to flash exposures. In the absence of the flash cube 18, the control pin 16 projects beyond the rim of the socket so as to serve as a manual switch for arbitrarily terminating a long time exposure, since the shutter will not close automatically due to low illumination of the photo-resistance.

Abstract: 493,616. Motors. VIDAL, C. H., GOSSLING, C. E., and SMALL ELECTRIC MOTORS, Ltd. March 11, 1937, No. 7222. [Class 35] [Also in Groups XXIV and XXVII] In an electric starter for an aero engine, a rod 111, Fig. 1, extending through the motor shaft 30 is normally retracted by a spring 90 and carries at one end the armature 113 of an electromagnet 92 controlled by the starter switch, whereby, on closing the latter, the armature 113 is attracted and moves the rod 111 to engage a dog member 63 with the corresponding member on the engine shaft through a spring 91. At the same time, two contact plates 94 are bridged by a spring- mounted member 93 carried by the armature 113 so as to energize the motor. Each brush holder of the motor comprises a sheet-metal socket 97 housing the brush 98, Figs. 1 and 4, and formed with lugs 99 riveted to an insulating ring 96 and with a bracket 105 to which is attached a terminal post 106 passing through the ring 96 and an insulating bush 107. A pair of flexible leads 101 extending from each brush is secured to a member 102 secured to the bracket 105, and a spring 104 abutting against the member 102 serves to apply the brush against the motor commutator. The ends of the posts 106 are slotted to receive conductor strips 110, Fig. 3. Leads to the field coils are connected through posts 108, 109, the former of which is connected to a pair of brushes and the latter of which is connected to one of the contacts 94.

Title: Improvements in or relating to a method of securing articles in a package
IPC: B65B9/02
Filed: 1947-03-17
Abstract: 622,355. Packing. KARTRIDG - PAK MACHINE CO. March 17, 1947, No. 7289. Convention date, Oct. 8, 1941. [Class 94(i)] A method for securing articles such as sausages in a unitary package which includes a supporting strip 1 with abutting articles 3 tangentially secured thereto comprises the feeding of a strip towards a securing zone, securing a second strip 2 thereto, feeding the strips forwardly and the insertion of one of the articles between the strips, moving the strips and article forwardly and sealing the strips together about the article, moving the strips and article to provide space for securing the next article, and so on. In the construction shown, the strips 1, 2 are fed from a platform 12 on to a roller 9 having a compressible surface 11. A head 14 having a heating element 20 and perforating teeth 16 may be lowered into engagement with the strips 1, 2 against the roller 11 by means of a handle &c., (not shown), connected to the head 14 by a rod 23 and links 24. A casing 25 completely surrounds the head 14 and is in slotted engagement with the rod 23. Springs, (not shown), act between the rod 23 and the casing to urge the casing into a normal position which covers the perforating teeth 18. When the head 14 is pressed against the strips 1, 2 the teeth 18 move downwardly relative to the casing 25, and the strips which are coated with heat-responsive adhesive are sealed and perforated. Alternatively, the strips may be secured by other means such as staples. The strips may be of different widths and may be at least as wide as the articles. The strips may be of differing degrees of rigidity, for example the lower strip 1 may be of cardboard and the upper strip 2 may be relatively flexible. The perforations may alternatively be dispensed with or may be replaced by marginal notches capable of intiating tearing.

Abstract: 789,929. Making artificial wood boards. BIBBY, R. D. March 14,1956 [March 15, 1955], No. 7924/56. Classes 70.and 87(2). An artificial wood board 30 is formed by extruding wood chips and a binder, e.g. urea formaldehyde resin, between heated platens 22, 23. The maximum dimension of the chips lies within the range of from 0À5 to 0À9 of the thickness of the board. It is stated that because the chips are of such a size they become disposed endways in alignment with the thickness of the board, during extrusion, although the ends of the chips near the surfaces of the board are inclined rearwardly to give them an arcuate formation. The material in the hopper 20 may be agitated by rotating members 29 or by vibration. The mixture may comprise hard woods, e.g., ash, oak, and hickory, soft woods, e.g. pine and cedar, the resin, flour, and a lubricant. Specification 784,179 is referred to.

Abstract: 773,312. Electrically conducting transparent films. GENERAL ELECTRIC CO. March 18, 1955 [March 19, 1954], No. 8015/55. Class 37. A film of titanium dioxide is rendered electrically conducting by covering it with a layer of finely divided zinc and baking it at an elevated temperature, such as 550-660‹ C., in a non- oxydizing gas, such as hydrogen, nitrogen or hydrogen sulphide. The baking is effected for at least an hour in a glass or refractory oven 13 through which the gas is passed, the powdered zinc 15 being placed on the film 12 resting on a glass plate 11. The film thickness may be measured by optical methods when greater than 0.7 microns and by observance of change in colour below 0.7 microns, a thickness of between 0.2 and 0.4 microns being most suitable for electroluminescent screens as used in cathode ray tubes.

Class 46 [Also in Group XXIX] In an automatic filtration plant control system. responsive to demand wherein each of the units, e.g. 6, 7, in parallel respectively in a stage, e.g., 3, 4, of the plant is provided with means, controlling the unit water level, responsive to the next down. stream water level and comprising a flow adjusting device, e.g. 15, 16, at the downstream end of the unit, a water chamber, e.g. 40, associated with the device, means actuated by the head of water in the chamber for operating the device to control the passage of water inversely to the level in the chamber to keep the level in the chamber substantially constant at C, and an accurately sized orifice, e.g. 17, 18, downstream of the device for delivering into a common collector, e.g. 10, 11, for all the units under a head h' formed by the difference of water levels in the chamber and collector, a feeding canal e.g. 8, 9 provides a common inlet level for all the units of a stage fed from all the units of the next upstream stage. When the demand for filtered water increases at 5 the level in collector 11 tends to decrease and lower the level in chamber 40 so that the device 16 allows more water to flow from filter 7 to maintain the level. These steps are carried by degrees up to the decantirig reservoir 2 where an inlet adjusting device 12 allows more raw water to enter the plant. The level D in the collectors when the orifices are unwatered corresponds to the maximum flow. Before each stage level adjusting devices 13, 14, may be provided to stop the upstream level of the next. downstream stage at a predetermined level, but if they are dispensed with, the feeding and collecting canals are combined and the walls of the lower stages built up to accommodate large level variations. The adjusting devices may consist of balanced valves and may be operated by the level in a branched water chamber or a manometric capsule. A main pipe containing any device e.g. an automatic throttle valve, preventing the pressure in it decreasing below a minimum value may replace the collector.
