Title: Liquid heater
IPC: F24H1/12
Filed: 1974-07-31
Abstract: 1484191 Liquid heating devices THERMO ELECTRON CORP 2 July 1975 [31 July 1974] 33810/74 Heading F4A A liquid heating device 12 (in particular a central heating water heater) comprises inner and outer walls 14, 16 defining a passage 18 for liquid to be heated, a source of hot gas 44 directed into the space defined by the inner wall, and a series of baffles 60, 62, 64, 66 through which the hot gases must pass in turn and which are arranged to direct the gases substantially normally toward the wall; the inner wall being the sole means of separation between the hot gases and the liquid to be heated and may be provided with heat exchanging fins in the passage 18. Fig. 1 shows a water heater housing three devices 12 connected in parallel. Water is passed down each passage 18 from inlet 28 to outlet 26 and vanes 92 give it a helical motion. Blowers 46 supply combustion air under pressure to burners 48 and a temperature sensor turns on the burners when the water temperature falls below a predetermined value. Each of the baffles is top-hat shaped with perforations 82 and all are secured to a rod 86. When the hot gases are passing over the baffles they expand to fit tightly on the wall 14 and when cool can be withdrawn on the rod 86. A layer of insulation 68 is placed about each outer tube 16.

Title: Improvements in web feeding mechanisms for tabulating and like machines
Inventor: TAPERELL GEOFFREY LESLIE
Filed: 1958-10-23
Abstract: 887,324. Typewriters &c. SMITH & SON (ALACRA) Ltd., W. H. Oct. 23, 1959 [Oct. 23, 1958], No. 33921/58. Class 100(4) A web-feeding mechanism for use in, or as an attachment for, a tabulating or like typewriting machine, comprises a web-feed drive, an escapement mechanism operable to restrain rotation of the web-feeding mechanism to single line-space movements in response to signals from the tabulator or line machine, such restraint being releaseable to effect a long feed, and a program member for stopping the web after a predetermined continuous long feed. A top web 22 is fed by pin wheels 32, 33 on shaft 30 and a condensed record web 21 is fed by pin wheels 35, 36 on a shaft 34. The shafts are geared together and either one or the other is driven by a constantly running motor. As shown the shaft 34 is driven by gear 46 from gear 45 on a shaft 44 secured to the driven side of a jamming ball or roller type clutch, the driving side of the clutch being operated from the motor by gear 41. The drive to the shaft 34 to stop feeding, is controlled by three ratchet wheels and associated solenoids SOL1, SOL2, and SOL3, and pawls 60, 61, and 68 respectively. The teeth of the ratchets engaged by pawls 60, 61 are staggered so that when the solenoids are alternately energized a line-by-line escapement feed is permitted. To effect a long feed a long feed signal is received direct from the tabulating machine, or a notch 78 in the program tape 73, Fig. 8, causes operation of a switch lever 79. This operates both escapement solenoids SOLl and SOL2 so that the clutch engages continuously until the driven side of the clutch is stopped by the engagement of the pawl 68 with the third ratchet 59 through a predetermined opening 76 in the program tape 73. Pawl 68 is released next time either SOLI or SOL2 is energized. In a modification a notch equivalent to notch 76 operates a second switch lever to stop feeding of web.

Filed: 1931-12-08
Abstract: 390,571. Cables. WILLIAMS, A. W., Redhill, Arnold, Nottinghamshire. Dec. 8, 1931, No. 34067. [Class 36.] In a cable of the trailing type comprising a plurality of metal-sheathed power cores and an earth conductor, the power cores are disposed, with their sheaths in contact, to one side or substantially to one side of a line drawn through the centre of the cable, the earth conductor being disposed on the other side of this line at the maximum practicable distance from the power cores. In the construction shown, insulated power cores 15 having metal sheaths 16 are laid spirally with an insulated earth conductor 11 around a rubber centre 10. The power cores lie to one side of a diameter of the cable with their sheaths in contact and are spaced from the earth conductor 11 by the centre 10 and also by rubber pads 18. To ensure continuous contact between the metal sheaths 16, bare earth conductors 20 are disposed in the outer interstices between the power cores and are adapted to contact with the sheaths of adjacent cores. The cable thus formed is wrapped with insulating tape 21 and enclosed within a vulcanized rubber sheath 22 which may be reinforced with a helically applied cord 23. The sheaths 16 of the power cores are preferably formed by winding tapes, consisting of woven or plaited metal strands, over the insulated cores.

Lathes; copying and reproducing mechanism. -A copying mechanism of the type described in Specification 147,978 is provided with a cross slide actuated by a roller engaging the templet and mounted on the oscillating copying-lever which is mounted on a shaft carrying a slide connected by lever mechanism to the tool lever arm. The bed 1 carries a slide 3 longitudinally traversed by a spindle 2 and provided wich guideways supporting cross slides 6, 7 carrying respectively the copying lever and the tool arm. The main spindle 16 carries a work-supporting face plate 67 and a square templet 15, the latter being fitted with projecting studs 17. The corners of the studs and the templet are concentricallv rounded off. The slide 6 carries a bearing 11 having a lateral arm 12 provided with a bolt on which is mounted a roller 14 spring pressed against the templet. The copying lever 19 pressed against the studs 17 is mounted on a shaft 22 journaled in bearings 11, 23 on the slide 6 and carrying a member 24 having a slide 27. The latter carries fulcrum pins connected by rods 29, 30 to a double-armed lever 32 rigidly mounted on a shaft 40 journaled in bearings in the slide 7. The shaft 40 is provided with a guide for the adjustable tool slide 44 carrying a tool 47 and the slides 6, 7 are connected by a lever 48 pivoted on a pin 57 adjustable by means of a hand-operated spindle 60 to vary the scale of the reproduction. In operation the tool slide 7 is first adjusted by means of screws 56 so that the ratio of the distances of the axis of the shaft 40 and the axis of rotation of the lever 19 from the work axis, is equal to the linear scale of reproduction. The screws 56 are then tightened and the tool holder 43 gradually advanced until the work is finished. The tool 47 may be replaced by a rotary tool for performing milling or grinding operations while for boring the tool 47 is mounted parallel to the machine spindle. Specification 195,765 also is referred to.

Title: Improvements relating to shutter mechanism for photographic cameras
IPC: G03B9/14
Filed: 1931-12-14
Abstract: 386,104. Photographic shutters. BARNWELL, A. E. and BARNWELL, E., Westerly, Barnt Green, Worcestershire. Dec. 14, 1931, No. 34546. [Class 98 (i).] In shutter mechanism of the kind comprising a pair of spring-controlled pivoted d blades d, Fig. 2, which are moved in opposite directions by a pin g to uncover the aperture, the pin g is carried by a yielding extension h of a swing- ing bar connected to the free ends of two substantially parallel pivoted links k. The blades pivot about pins at their lower ends on a back-plate b<1>, Fig. 7, and are formed with opposed inclined faces between which the pin operates. The pin extends through a slot in a plate b, on which the links k are pivoted at k<1>, k<1>, and is formed with an inclined face so that it rides over the faces f when moving upwards but forces them apart during its descent. The links k are controlled by a spring r and are actuated by a hand-lever m. The latter has a lug o, Fig. 9, which co-operates with and lifts a lug p on the bar j during the first part of the movement of the lever m, and disengages therefrom to effect a rapid movement of the blades when the lever is fully depressed. The time of exposure can be varied by altering the tension in the spring r by means of a lever s. As shown, this spring is arranged on a peg x and rests with one arm on the upper link k and with the other arm in a hook y of the lever s. For " bulb " exposures, the lever s is moved into its extreme anticlockwise position and in this position depresses a spring-controlled pivoted member u to bring a lug v on this member into the path of the lug p on the bar j. The lugs engage only during the downward stroke of the bar j and are so disposed that the bar is arrested when the shutter blades are fully extended. During the first part of the movement of the lever m, a cam surface w thereon moves the bar j bodily away from the plate b and thus allows the lug p to ride over the lug v. Disengagement of the lugs p, v is effected when the lever m is released and the surface w is again brought into engagement with the bar j.
