Filed: 1934-03-06
Abstract: 434,666. Watersupply. ALTENKIRCH, E., 56, Bahnhofstrasse, Neuenhagen, near Berlin. March 6, 1934, No. 7102. Convention date, March 10, 1933. [Class 68 (i)] [See also Group XIII] The alteration of the water vapour content of air for obtaining a supply of water is effected by treating wood in a repeated cycle with air. In the form shown, a chamber with wood-filled compartments K and L, K facing west, L east, has a condenser M. In the morning there is an air flow from aperture L<4>, over the wood in L, through the condenser, over the wood in K, and out at K' or through a cooler N. In the afternoon the flow is reversed. After several cycles, the effect is that the air passes over hot, wet wood, then yields up the water so acquired in the condenser, and is further dried by cold, wet wood.

Title: Improved apparatus for supplying compressed air to deep-level mines for power and/or cooling purposes
IPC: E21F17/10
Filed: 1936-03-09
Abstract: 461,779. Pneumatic power transmission. WALKER, W. J. March 9, 1936, No. 7125. [Class 8 (ii)] [Also in Group XIII] In apparatus for supplying compressed air to deep levels in mines for power or for cooling purposes, air delivered from a compressor 11, Fig. 1 at the surface is expanded in a motor 13 or otherwise cooled and then led down a conduit 16 to another expansion motor 19 at the deep level, from which a part may be led off through branch pipe 22 for power or cooling purposes while the remainder is led back to the surface compressor by a conduit 18 in heat exchange with the down-flow conduit. Preferably the conduits are concentric, the colder one being inside the warmer one. The surface expansion motor may assist the compressor motor 14 and a heat - exchanger 23 for the return and the compressed air may be provided at the surface. The air may be circulated repeatedly in a closed cycle and cooling may be effected to such a degree that the air is liquefied at the deep levels. It is stated that by suitable adjustment of the work done in the surface and deep level expansion motors the descending air may acquire a pressure gain due to depth greater than the pressure loss in the ascending column. Fresh air may be admitted through a valved branch 10 to the compressor. In the modification shown in Fig. 2, air compressed in a compressor 26, expanded in a surface motor 27 and led to the deep level motor 31 is returned to an auxiliary compressor 34 and motor 35 at the surface and led down again through a third concentric conduit 33. A valved byepass conduit 38 is provided in front of the auxiliary compressor. In a further modification compressed and expanded air is delivered through a descending innermost conduit for use at the deep level and is cooled by a second stream of air circulating in a compression-expansion cycle in heat exchange with the first.

Title: Paper Security Validation Apparatus.
IPC: G07D7/00
Filed: 1967-02-17
Abstract: 1,179,279. Photo-electric currency authentication. TRANSMARINE CORP. Feb.17, 1967 [Feb. 24, 1966], No. 7755/67. Heading G1A. In an apparatus for authentication of paper securities having parallel equally spaced straight lines and comprising means to receive and hold a security in a substantially flat position and move it into and in a testing area, a reticle having equally spaced parallel lines corresponding in number per unit of length to those expected on the security, disposed close to and parallel with lines on the security to create moira fringes when the security is moved in the test area, and means to pass light through the portion having parallel lines to a photocell, a counter provides a validation signal when a predetermined minimum number of light-dark areas are monitored in response to movement of the security through a predetermined distance relative to the reticle. The invention is described with reference to dollar bills in a change machine in which the testing is initiated by a micro-switch operated by the leading edge of the note during insertion. The lamp is run below its rated voltage to increase the infrared, and the reticle in front of the photo-cell which is screened apart from a small aperture may have parallel lines in the direction of insertion or at right angles thereto, the note being moved at right angles to the direction of insertion after reaching the test area in the former case. The note may be further validated by the amplitude of the signal resulting from the lightdark contrast and a relid test may initiate a general inspection of the note by a single source on one side and a plurality of detectors on the other. Four light-dark pulses produced at the bottom of apertures by a small movement may be sufficient, and may be counted on a pair of flipflops, after amplification and shaping. A satisfactory note is taken into the machine by a pair of motor driven rollers and the change pay out is initiated. Two areas may be tested by two reticle devices.

Abstract: 1,181,075. Moving band filter. P. G. KALMAN. 21 Feb., 1967, No. 8122/67. Heading B1D. [Also in Divisions B4 and B5] A movable filtering ribbon 1, of woven stainless steel or Nichrome (T.M.) extends directly or obliquely across passage 16, which carries molten rubber or plastics from the screw to the die of an extruder, some of the rubber/plastics being maintained in a solid or plastic state in ribbon entry and exit slots 14, 15 extending through ports 3, 4 which have electric/hot fluid heaters 6, 7, 10, 11 and coolant passages 8, 9, 12, 13 whereby their temperatures are controlled. Ribbon 1 is moved intermittently or continuously across the passage, impurities being removed as a coating 22 on the ribbon. For intermittent movement, ports 3, 4 are normally cooled to keep the plugs of material in slots 14, 15 solid, and periodically, under control of a timer or pressure switch, either ports 3, 4 are heated or electricity is passed through ribbon 1 itself to melt the plugs. The pressure in passage 16 then extrudes material and ribbon from slot 15 by virtue of its larger crosssection. Alternatively, ports 3, 4 are held at intermediate temperature, material extrudes through both and the ribbon advances continuously (0.42 inch per hour). Ribbon movement may be effected or assisted by a pneumatic ram-operated toggle device on the exit side (Fig. 11, not shown) and retarded by braked rollers on the entry side (Fig. 12, not shown). Instead of or in addition to controlling movement by temperature, the exit slots may be variable in width or partly obturated by grubscrews (Figs. 7, 8, 9, not shown). The exit port may comprise several individually cooled/heated sections (Fig. 4, not shown), and its slot 15 may be tapered, parallel sided or curved (Fig. 10, not shown). In Fig. 13 (not shown), some molten plastics from passage 16 is bled through passages (75, 76) to act on the solid plug in an outer, widened part of the exit slot. In Fig. 5 (not shown), the exit port comprises alternate metal fins and ceramic spacers, for cooling by natural or forced convection. Where it crosses passage 16, ribbon 1 is backed by a disc 17, formed as a grating by two sets of slots cut into opposite faces and intersecting. Ribbon 1 may be an endless band, cleaned by melting or solvent action.
