Title: Improvements relating to apparatus for testing the dryness of hair
Inventor: BALL DENIS ARTHUR
IPC: A45D20/00
Filed: 1948-10-22
Abstract: 642,877. Determining physical qualities of materials. EUGENE, Ltd. Oct. 22, 1948, No. 27522. [Class 37] Apparatus for determining the degree of dryness of hair by measuring its resistance comprises two spaced electrodes 11, Fig. 1, forming a probe to be placed in the hair and connected in a circuit, Fig. 2, which indicates the resistance on a meter 16, or operates a warning device when the resistance reaches a predetermined value, or operates a relay 25 to open the heating circuit at a predetermined value of resistance. The resistance of the hair, together with resistances 19, 20 form a potentiometer for biassing the grid of valve 13 so that when the former is high the grid is approximately at cathode potential, causing the cathode current to be sufficiently large to energize relay 17, breaking one lead from the probe by contacts 22 and cutting off the main power supply by de-energizing relief relay 25 through contacts 24. A plurality of probes may be employed in parallel, and the meter 16 may be replaced by other forms of visual or audible indicators.

Title: Means for removing tiles from pallets
IPC: B28B13/06
Filed: 1935-10-05
Abstract: 461,293. Endless - chain conveyers. CARTER, G. H. Oct. 5, 1935, No. 27526. [Class 78 (i)] [Also in Group V] Tiles carried on a succession of pallets supported on a conveyer are removed from the pallets one by one by means of a reciprocating plunger arranged at right angles to the conveyer and on a level with the tiles. As the pallets pass before the plunger the latter moves forward and strikes the edge of the tile and dislodges it from its pallet. A device may be provided to slide the loosened tile completely from its pallet on to a second conveyer or platform. Fig. 1 shows a conveyer consisting of two endless belts 5 which carry pallets, each of which supports a tile 21 as shown in Fig. 2. The belts are driven from a shaft 6 which carries a cam 11 which causes a lever 13 to move the plunger 16 against the edge 21a of the adjacent tile and loosen it from its pallet. The plunger is returned by a spring 18. The loosened tile is removed to a platform 29 by a bar 28 carried by chains passing over cog wheels 24, 25 which are rotated from a shaft 22. In a modification, the plunger remains stationary, the pallet being given a transverse movement to force the edge of the tile against the plunger.

Title: Thermoelectric ice freezing apparatus
IPC: F25C5/08
Filed: 1965-06-29
Abstract: 1,069,587. Thermoelectric apparatus. T. M. ELFVING.- June 29, 1965 [Feb. 12, 1965], No. 27579/65. Heading H1K [Also in Division F4] A thermoelectric ice freezer comprises a plurality of thermoelectric elements connected by conductive bridges and means for continuously circulating water over the cold bridges to form ice thereon and for reversing the current so that the ice partially melts and ice blocks fall into a lower contains. In Fig. In thermoelectric elements 17, 18 are mounted so that metal tubes 22 bridgp the cold junctions and metal tubes 21 bridge the hot junctions; metallic portions of the tubes are separated by insulating portion 23. Water is sprayed into tubes 22 from pipe 40 to form ice, the unfrozen water flowing, into reservoir 14 whence it is recirculated by pump 15. When sufficient ice is formed, a switch is operated to reverse the direction of current to the thermoelectric elements so that heat at the cold junction partially melts the ice blocks, allowing them to fall into ice reservoir 16 after deflection by screen 43. In a modification, ice is formed by spraying water upwards into inverted cups which form the cold junction bridge pieces. In another example, ice is formed on one surface of flat discs; the other surface being connected to the thermoelectric elements; two assemblies of such discs may be mounted opposite each other so that solid ice pellets form between each pair of discs.

Oct. 6, 1931, No. 27689. [Class 108 (ii).] The rear wheels of a six-wheeled vehicle are mounted on axles 1, 5 offset from the centres of suspension springs 2, 6, the adjacent ends of which are interconnected by shackles 19, 20, link 17, and bell-crank levers 11, 12, each articulated on the vehicle frame within the length of the springs 2, 6 respectively.

Title: Map indicating device
IPC: G09B29/06
Filed: 1965-06-30
Abstract: 1,056,623. Indicating-apparatus. TELDIX LUFTFAHRT - AUSRUSTUNGS G.m.b.H. June 30, 1965 [July 2, 1964], No.27712/65. Heading G1J. Apparatus for indicating the position of a craft on a map of its operational zone comprises a number of alternative overlapping sections of the map which can appear in a visible map field and a series of equally spaced indicator marks driven across an indicating field contained in the visible map field and is characterized in that the width of the indicating field is greater than the distance between adjacent marks and a masking plate geared to their drive allows only one mark to be visible at a time. A translucent roll map may be formed by dividing a map of the zone divided by grid lines into widths "t", forming overlapping sections by adding a piece each side of a grid width and joining adjacent sections end to end to form a roll 21. To indicate the position of a craft the roll is turned to bring the appropriate part of the appropriate section into line with equispaced holes 33 at distance "t" apart in an endless opaque band 22 driven by a motor 27 in accordance with a co-ordinate derived from a navigational computer corresponding to the position of the craft. Red light emerging from a slit 32 in the covering of a neon lamp 31 passes through a slot 36 in the mask 35 arranged to allow one light spot 34 to be visible to mark the craft position on the map. To allow the mark 34 to move over a grid line into an overlap piece, the mask 35 is driven with the band 22 by the motor 27 through gear train 47 48, 49 and arm 55. The arm 55 engages the left or right side of a wing disc 41 at the moment the mark 34 crosses the right or left grid line. The disc 41 drives the mask 35 through shaft 39, sector 38 and rack 37 until a wing 44, 43 on the disc 41 actuates a micro switch 57, 56 to energize an electromagnet 52 which moves the arm 55 axially to disengage it from the disc so that a spring 46 can return the disc and mask its initial position. The micro switches also control a drive to the roll 21 to bring the appropriate adjacent section of the map into viewing position whilst an adjacent mark 33 is unmasked and indicates the position of the craft. In another embodiment Fig. 5 (not shown) the indicating spot is the point of intersection of transverse slits equispaced along two opaque bands moved at right angles to one another over the section of the map for the time being in the visible map field in accordance with co-ordinates derived from the computer according to the crafts position.

Abstract: 510,121. Toy electric railways ; remote control. VOELK, E. Sept. 27, 1938, No. 28103. Convention date, Aug. 5. [Class 132 (iii)] [Also in Group XXXVII] A vehicle for toy electric railways is controlled from a distance by current impulses by means of a switch magnet which sets the switch mechanism, and in which a switch magnet is employed which responds only to a voltage higher than the running voltage of the motor of the vehicle, and has means for breaking the motor circuit of the vehicle while. the higher voltage is acting on the switch magnet. Current is fed to the motor o, p from the rail collectors q, r through contacts on a switch drum, corresponding spring contacts v, v<1>, v<2>, v<3> and contacts d, e maintained closed to prevent interruption of the current to the motor by the action of a blocking lever m on the armature b. Application of a high voltage current energizes the coil a to attract the end h of the lever m to release the armature b which is then attracted and causes the nose piece f of the lever n to rotate the ratchet g, which rotates the switch drum x, one quarter of a revolution at a time to bring the contacts and spring contacts together in turn.
