Title: Improvements in or relating to record cards and methods of making them
IPC: G06K19/02
Filed: 1961-06-16
Abstract: 958,946. Picture mounts. EASTMAN KODAK CO. June 16, 1961 [June 20, 1960], No. 21781/61. Heading A4X. [Also in Division G4] A record card 10 is provided with a series of unconnected slits 12, 13 to define a removable core 14, and a thin sheet or strips of adhesive material is or are secured to the marginal portions of the card surrounding the core to overlie the slits 12, 13 and at least part of the core. In use, the core is removed to provide an aperture into which an insert such as a film or photographic print can be placed and retained by said adhesive material. The adhesive material comprises a sheet 18 of cellulose acetate coated with a thermosetting or pressure-sensitive adhesive. In the latter case, the core is separated from the adhesive material by a layer of wax or "Teflon" (Registered Trade Mark) applied to the core. Preferably, the sheet 18 is blanked out at its centre to form a rectangular frame 17. Alternatively, strips of adhesive material are secured along each edge of the card adjoining the core to overlie part of the core and form the frame. The bridge portions 15, 16 connecting the core to the card are cut, broken, or punched out, to disconnect the core from the card. To facilitate breaking of the bridge portions, they are scored along lines 27 on one or both sides of the card and may be tapered as shown in Fig. 7, whereby a rectangular aperture is obtained when the core is removed. Alternatively, the bridge portions taper towards the core and the score lines are positioned in line with the inner edges of the slits, whereby the bridge portions remain projecting into the aperture when the core is removed, to engage corresponding notches in the film edge and locate said film in position. Data relating to the film to be secured to the record card is entered on the case in the form of punched apertures 30, 31, which are covered by small pieces of a pressure-sensitive adhesive material 32, 33 prior to removal of the core from the card. Specification 615,577 is referred to.

A washer 7 of non-conducting material is clamped between a plate 4 and the plate 5. To one of the plates 5 is screwed an attachment 8 which is detachably connected to driving gear so that the body 1 may be rotated during electrodeposition of the metallic sheath thereon. The attachment is coated with varnish, wax or like material to prevent metal being deposited thereon. The lower end of the body 1 is preferably covered by a cap 9 of non-conducting material screwed on the plate 5. Specification 561,312 is referred to.

Abstract: 1,065,788. Testing physical qualities of materials. V. PERLIK and B. VODRAZKA. May 24, 1965, No. 21959/65. Heading G1S. A method of evaluating the relative abrasive qualities of samples of abrasive material includes rubbing each of the samples 35 of abrasive material against one end of a test piece 16 and measuring the amount of the test piece ground off by each sample. The apparatus comprises a housing 1 on which is erected a column 25 surrounded by a rotatable sleeve 27 having a horizontally extending arm supporting a cylindrical guide 15. The guide contains a tube 26 in which a testing rod 16 is slidably arranged. The abrasive material to be tested is fixed on to a circular plate 10 by a ring 11 and the testing rod 16 inserted in the  tube 26, the weight thereof being adjusted by a balance weight 20. A shifting rod 17 carrying a scale 36 Fig. 6 (not shown) is placed in position with the lower end of the rod 17 abutting the top end of the testing rod 16. Above the shifting rod 17 is a vessel 22 connected by a tube 24 to a container 23 filled with water.

Continuous-discharge apparatus with stationary containers.-Relates to high-speed machines for beating or thrashing liquids, preferably in the presence of air, and more particularly for thrashing mixtures of cocoa liquor, sugar, and other ingredients in the manufacture of chocolate fondants. The machine is of the type comprising a stator and a high-speed rotor with blades, pins, or projections working in the clearance-space between the stator and rotor. According to the invention, the surfaces of the stator and rotor that bound the clearance-space are surfaces of revolution of any shape other than a plane horizontal surface with or without a cylindrical or conical surface at its periphery. The surfaces may be conical, spherical, or dome-shaped, or formed by the revolution of a quadrant or similar curve about an axis substantially tangential to the same at a point approximately at one of its ends. Fig. 1 shows a conical rotor 4 with pins 22 mounted on a vertical shaft 3 within a conical stator 10 surmounted by a feed-hopper 12. The wall 10 is hollow to serve as a heating-jacket.

[Also in Division H3] A switching circuit, responsive to touch, comprises a switch 28 composed of a pair of complementary transistors 30, 31 with the base of each connected to the collector of the other, an A.C. power supply 20, 23 coupled to the emitters of the transistors, an input circuit connected between the base and emitter of one transistor (31) to supply a switching signal through a capacitor 27, and a bias circuit including a capacitor 35 and a resistor 34 connected in series between the base and emitter of the one transistor. A reverse bias for switch 28 is stored on bias circuit 34, 35, the charge being maintained through the zener breakdown of transistor 30 on the half cycles of the A.C. supply when line 18 is positive. A relaxation oscillator, comprising a neon lamp 10, capacitor 16 and resistors 21, 14, 15, 17 oscillates at a frequency (e.g. 2-4 Kc/s) much greater than that of the A.C. supply, the oscillations being normally of sufficient magnitude, after amplifier stage 24, to render switch 28 conductive when line 18 is negative. However, should antenna 12 be touched, e.g. by the human hand, the magnitude of the oscillations is so reduced that switch 28 is not rendered conductive, and current is diverted through relay 38 to close contact 41. Current flow through relay 38 during positive half cycles at line 18 is prevented by diode 37, but when antenna 12 is touched, and thus switch 28 is maintained non- conductive, relay 38 is maintained energized during positive half cycles by the charge stored on capacitor 40.
