Title: Particulate matter counting apparatus
IPC: G06M1/10
Filed: 1961-09-29
Abstract: 938,756. Measuring particle flow. SANBORN CO. Sept. 29, 1961 [April 3, 1961], No. 35417/61. Class 40 (3). [Also in Group XL (c)] Blood cell or other particle concentration in a flow of fluid is measured by their interruption of light from a projector 1 to a photo-multiplier tube 11 causing an equal rate of pulses P to be generated by the tube and passed to a double triode limiter and amplifier tube I, II integrating the pulses across a meter M as a measure of their recurrence frequency. To compensate for larger particles producing broader pulses P producing an error on the meter, the larger amplitudes due to the broader pulses are, before limiting in tube I, proportionally passed by a potentiometer R 1 , R 2  to the grid of output tube II to reduce the output pulse amplitude in proportion to their width. Transistors may replace the valves, and recorders or numeral displays the meter M.

Abstract: 381,786. Cases for cosmetics ; pads. MAILLARD, J. E. B., Nogent-le-Roy, Eureet-Loire, France. Dec. 22, 1931, No. 35439. Convention date, Dec. 24, 1930. [Class 18.] A case for cosmetic is provided with a cover 16, a cuplike holder 9 for cosmetic or a pad impregnated with cosmetic, extensions on the holder to engage a helical screw 5 located to one side of the case, and finger actuating means for operating the screw. In an embodiment, Fig. 1, the cosmetic is a lipstick 14, and the screw is turned by a knob 8 attached to the lower or upper end thereof, the sliding movement of the holder in the case being facilitated by a roller 13. A ring and chain 18 are attached to the cover of the case. In a modification, Fig. 9, the screw, which comprises a spirally wound thread soldered &c. to a spindle, is turned by a toothed-wheel 115 extending through the sides of the case, through the intermediary of gear wheels 114, 107. The holder 9 is coupled to the screw by a threaded nut 110 which need not completely surround the screw ; and the cover 16 has a cut-away portion to receive a projecting part 103 of the case and is provided with a flange 123 by which the cover is gripped and pulled off. The wheel 115 may be replaced by a knob located outside the case and underneath the bottom wall thereof. In a further modification, Fig. 3, the holder 9 contains a pad 21 of felt, skin, &c. and the pad is impregnated by raising it until it contacts with cosmetic paste, or porous material, e.g. cotton or felt, saturated with liquid cosmetic situated in a reservoir 26 in the cover 16. The top of the cover is closed by a cap 27 held on by a spring 30 pivoted to sides of the cover. Bosses 22 attached to holder 9 facilitate its sliding movement in the case.

The cartons 25 lie along a pair of rails 2 and spindles 7, 8 carrying tracks 11, 14 each in the form of half a screw thread are rotatable so that the tracks engage and press down the carton walls. Spindles 7 are driven by a gear train and spindles 8 are driven by a chain drive from adjacent spindles 7. A shaft 18 and universal joints 17, 19 connect spindles 7 to the gear train 22-24. If a carton is warped a ring (33, Fig. 6) having a track that will bear on the top edges of a pair of opposite walls may be provided. The cartons are moved through the machine by a bar 32, Fig. 2, on an endless chain 31. To permit adjustment of rails 2 and spindles 7, 8 for boxes of different sizes the rails 2 can be moved away or towards one another by screw shafts 4 and the spindles are adjustable by screwed shafts 6 that move pushers 5 in which the spindles are mounted towards or away from the transverse centre line of the machine. The tracks 11, 14 could alternatively be solid helical bodies of a plastics material and the gear train 22-24 could be replaced by a chain gear.

In a pressure-operated micro-switch arrangement, an increase in pressure causes a corrugated tube 1 to move a lever 3 about a knifeedge 4 against the tension of springs 5 and 10 in order to operate the micro-switch 11 by means of an adjustable abutment 17. The switch may operate in one direction against the additive tension of both springs and in the reverse direction with the assistance of both springs. By suitable adjustment of a setscrew 13, the spring 10 may cease to affect the lever 3 before the micro-switch has moved in the reverse direction, thus providing for a pressure differential.

A fluid pressure cylinder 86 may alternatively or additionally be provided actuating the drilling means: When both are provided a foot operated valve controls the cylinder 86 and the handle 50 is locked relative to the platform 40. A lost motion pivot connection between the handle and drilling means 80 allows movement of the latter. The drilling means comprises an electric motor and chuck drive mounted within a housing 19 and coverplate 20. The drilling means is guided by two vertical guides (37) (Fig. 6, not shown) held in the platform and passing through bushes in the cover-plate 20, and by a guide pin 24 engaging the bottom of the housing 19. A screw adjusted stop (56) (Figs. 1 and 3, not shown) limits the upward movement, and hence depth of drilling, of the housing 19. A light source 68 gives a visual indication 66 of the operating of the machine and also supplies a light beam through a lens arrangement 64 which is aligned with the drill bit 32 axis so that the position where a hole is being drilled is visible from above.

Abstract: 1384413 Telephone exchanges SIEMENS AG 9 Aug 1972 [13 Aug 1971] 37137/72 Heading H4K In a telecommunication system in which a central control unit controls a space division switching network and a plurality of time division multiplex communication lines with converters for transmitting signals between those TDM lines and the control, unit, an additional converter is provided and arranged such that it can take over the function of any other converter while that converter is taken out of service for testing. The figure shows a stored program control unit ZS, one of the converters EKVn, a T.D.M. switch unit KFn and the additional converter EKVe. If converter EKVn is to be tested under control of unit ZS contact S 1 is closed so that both converters shown receive signals from the T.D.M. switch unit. Both units process these signals and supply signals to the central control but only the converter EKVn can supply signals to the switch unit KFn. After a period corresponding to the longest possible processing delay contact S2 is switched over disconnecting the output of converter EKVn from the switch unit KFn and connecting the additional converter EKVe thereto. The converter EKVn may now be taken out of use and contact S3 changed over to allow this converter to receive what it transmits and to perform self-checks.

Abstract: 302,662. Cosgrove, C., and Chadwick, A. E. Dec. 19, 1927, [Convention date]. Heating by electricity.-Metallic mesh for fencing, reinforced concrete roads, pipes, &c. of the kind consisting of longitudinal and transverse rods, wire &c. welded at their junctions, is made by uniformly moving the angularly disposed rods &c. past one or more electric welding heads so as to weld the junctions successively during the movement thereof. In one form, one or more heical rods &c. are wound on a number of longitudinal rods &c. to form a tubular mesh. In this case the longitudinal rods &c. are supported on a rotary collapsable drum parallel to which a travelling welding head is mounted. The welding head embodies a portable transformer 33 traversed by a screw. One terminal of the secondary is connected to two arms 56, Figs. 8 and 9, and the other to arms 58 passing over an insulated bolt 59. The arms 56 are in contact with weighted arms 62, 64 having fixed or revoluble contact members 63, 65 and the arms 58 are in contact with weighted arms 67 having a contact member 68. The rod &c. 75 to form the helix is led from a spool &c. through a tubular guide, on the transformer casing and is fixed at one end to the drum and coiled thereon by rotation of the drum and traverse of the transformer. The contact members 63, 68 engage successive turns of the helix and as the current passes continuously the junction B is preheated. When the longitudinal rods &c. 20 by rotation of the drum wipe over the contact 65 the current is increased to effect the weld. Tn making flat lengths of mesh the longitudinal rods 79 are drawn from spools by a continuously rotated drum over an endless con. veyer in which the transverse rods &c. 83 are supported. They are drawn under a series of welding heads, the contact members 87 of which are in contact with the longitudinal rods &c. so as to preheat the junctions. When the transverse rods &c. corne under the contact members the junctions are welded. The transformers may be single, two or three phase. In the form shown in Fig. 13 three phase transformers arranged star fashion by a conductor 94 are used.
