Title: Improvements in thermo-electric devices
IPC: H01L35/32
Filed: 1963-03-05
Abstract: 1,025,687. Semi-conductor devices. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. March 5, 1963 [March 8, 1962], No. 8731/63. Heading H1K. In a Peltier device comprising semi-conductor bodies 1 of bismuth telluride, alternately of P-type and N-type conductivity, and joined in series by soldered copper current bridges 2, copper sheets 5 and 6 are secured to, but electrically insulated from, the current bridges, by an adhesive layer 8 having embedded therein spacing means 9 which determine and keep constant the distance between the bridges and the sheets. The adhesive layer may be a thermally hardening substance of the ethoxyline resin type, which is substantially not plastically deformable by short duration mechanical forces. Alternatively the layer may be plastically deformable at the operational temperature of the device, or may react elastically to rapid mechanical stresses and plastically to slow mechanical stresses. The spacing means must be electrically insulating and may comprise glass pellets or rods, a perforated foil, Fig. 2 (not shown), an interwoven tissue of glass fibre, Fig. 3 (not shown), or a plurality of parallel glass filaments held taut by rods at each end, Fig. 4 (not shown). Where the volume of the spacing means is a substantial proportion of the volume of the adhesive layer, the physical properties, e.g. thermal - conductivity, of the adhesive layer may be largely determined by choice of the spacing means. The expansion coefficients of the adhesive and spacing means substance should be the same, at least over the operating temperature range of the device.

Abstract: 539,756. Operating belt-forks. HAZLEWOOD & DENT, Ltd., and HAZLEWOOD, G. W. May 20, 1940, No. 8918. [Classes 80 (ii) and 80 (iii)] The operating gear is locked in extreme positions and the locking effect is increased by any tendency of the belt to creep from one pulley to another. The belt fork 2 is mounted on a fixed bar 3 to which are also secured two collars 4, 5 each having a detent 6 the detents being reversely directed. Between these collars a catch 7, which may be loaded by a light spring, is mounted so as to slide along the bar 3 and have slight vertical movement relative thereto, and also to rock about a stud 8 connected by a rod 10 to a rockable stud 11 on the fork 2. The catch has reversed hooks 9 adapted for positive engagement by the detents 6. The detent collars 4, 5 are mounted on a plate 13 to which the actuating lever 12 is pivoted at 16. This lever moves under considerable resistance and, at its upper end, is apertured to form inclined faces 17, 18 adapted to be engaged by the substantially semicircular underside of a lug 19 on the catch 7. In the position shown in Fig. 1, any attempt to move the fork to the right by creep of the belt, would cause the lug 19 to ride up the face 18 and tip the hook 9 into tighter engagement with the collar 4. The lug 19 and catch 7 are lifted by movement of lever 12 to disengage the hooks and detents.

Title: Improvements in addressing machines
IPC: B41L47/18
Filed: 1928-03-26
Abstract: 314,363. Marks, E. C. R., (Spiegel, May, Stern Co.). March 26, 1928. Addressing-machines. - In ejector mechanism for addressing machines of the type in which cards, stencils. plates, or the like are fed along an horizontal guideway, means are provided adapted to engage one face of a card &c. and positively move it out of the plane of the guideway. The cards &c. are fed by an endless chain 2, Fig. 1, along a guide formed by rails 7, 8 to an aperture 10 over a shoot 25, Fig. 3, leading to a passage 24. The rail 7 is recessed on its underside to receive a flexible spring-pressed strip 11 bevelled on its upper forward face which serves as a support for one edge of the cards &c. as they are fed forward. The other edge of the card is supported over the aperture by a member 30 journaled on an eccentric 27 secured to a shaft 18 non-rotatably mounted in bearings on the machine frame. The member 30 is normally held by a spring 31 against an adjustable stop 34 so that its upper edge forms an extension of the rail 8. When the card &c. lies on the strip 11 and member 30, the chain 2 being stationary, an ejector 15, whihc is normally somewhat raised to permit the passage of the card &c., is actuated to swing on the shaft 18. As it swings, it causes the retraction of the strip 11 and grips the card &c., between itself and the member 30, thus carrying the card from the horizontal position to a vertical one in the passage 24. Owing to the mounting of the member 30 on the eccentric 27, it is retracted during the swinging movement so that the card &c. is released. The cards &c. are stacked against a follower 38 slidable on rails in the passages 24, and are held when the ejector 15 is retracted by spring- pressed abutments 40 which are arranged to be retracted by the presence of the card &c. when pushed forward by the ejector. At the end of the passage 24 a runway 42 and guides 45 direct the cards &c. into a tray 43 provided with a slidable follower 47. The inner end of the tray is supported on a shoulder 50 to which it is directed by a bracket 48 having flanges to retain the tray and a curved bottom for enabling the tray to be slid into position past the runway 42.
