Title: Internal Brake for Cycle Hubs.
IPC: B62L5/04
Filed: 1917-06-30
Abstract: 107,598. Schweinfurter - Pracisions - Kugel - Lager - Werke Fichten & Sachs, (Assignees of Raeker, H. T.). Dec. 31, 1915, [Convention date]. Band; blocks acting on drums or hubs; actuated by running axle or wheel; cone; energy-absorbing elements.-Two forms of internal brake, particularly for cycle hubs, are described. According to one form, the brake is actuated by the rotary movement of the hub through a friction clutch controlled by the driver. In the second form, a braking-member engages the hub so as normally to rotate therewith and can be held stationary to produce a braking action. Fig. 1 shows one construction of the first form, in which the member 5 is adapted to be moved longitudinally to expand the brake sleeve 4 against the hub, by a member 6 which screws along a threaded part 24 of the fixed axle 20 when rotated by engagement with a clutch member 7 having a key conr,exion with the hub. The friction between the clutch members adds to the braking action. The clutch member 7 can be moved into and out of engagement with the member 6 by the slide 9 working in a slot in the axle and actuated by the rod 11 and manual or other connexion. The expanding member 5 is shown as having a ball bearing on the member 6. A spring 3 returns the parts 5, 6 to the release position. The brake sleeve 4 is held against rotation by engagement of a slot therein with a projection 23 on the expanding member 2. According to modifications, the screw thread 24 may be arranged between the members 5 and 6. The friction clutch may be arranged between the hub and a coupling member which is in permanent engagement with, but movable axially relatively to, the member 6. The brake-actuating member may rotate with the hub and the co-operating member be connected to the stationary axle by a friction clutch. The brake sleeve may be expanded by a roller lock. A laminated coupling may be used instead of the cone coupling. The second form of brake comprises a number of rings 31, 32, 33 of which one or more, according to the intensity of braking action required, can be locked against rotation by a slide 35 movable in a longitudinal slot in the axle 20 and in grooves in the rings. As shown in Figs. 3 and 4, the rings carry on their peripheries a number of spring members 36 which are adapted to engage projections 37 upon the hub so that normally the rings are rotated but when the rings are locked the projections slide over the springs. Fig. 5 shows the rings provided with spring-controlled sliding blocks 38 instead of the springs 36.

Title: Improvements in or relating to the Regulation of Internal Combustion Engines.
IPC: F02D15/00
Filed: 1919-04-15
Abstract: 125,970. Etablissements Ballot, (Assignees of Guillon, W.). Dec. 3, 1917, [Convention date]. Spray carburettors. -The compression in an engine is maintained constant at varying altitudes by drawing the air therefor from a reservoir L, such air being admitted by a valve K, the opening of which is resisted by a piston F subjected to the varying pressure of air drawn from the atmosphere and forced into a reservoir D by a compressor A. The reservoir L supplies air to a carburettor M, the float chamber 0 of which is closed to the atmosphere and is connected to the reservoir by a pipe N. A spring R tends to open the valve K. A calibrated hole E in the reservoir D serves to prevent the pressure therein from becoming too high. The hole E may be dispensed with, some of the compressed air being then permitted to return to the atmosphere by making the stem of the valve C of such a length that it is actuated by the piston, and by mechanically actuating the pump inlet valve B.

Title: Method of and device for controlling the flow of liquid in a closed pump circulation
IPC: F24D19/10
Filed: 1932-04-05
Abstract: 400,199. Moistening air. ROSSER & RUSSELL, Ltd., Romney House, Marsham Street, and NAYLOR, E. J., 59, St. John's Wood Court, both in London. April 5, 1932, No. 9789. [Class 55 (ii).] A method of controlling the flow of liquid in a closed pump circulation for air conditioning or humidifying, consists in thermostatically controlling an auxiliary flow of liquid, which in turn regulates the flow of one or more continuous streams of heating or cooling medium supplying the working circuit. A pump E draws water from a reservoir R and a second, cooled, reservoir R<1> through a mixing valve V and delivers it to an air washer O. A byepass K through a temperature controlled valve J and filter H connects the delivery side of the pump E to the mixing valve V. A leak L connects the byepass K with the suction side of the pump or the leak may be arranged through the valve J itself. If the temperature of the water flowing through pipe F falls the valve J opens to allow the pressure of the water on the delivery side of the pump to act through byepass K on the piston of the mixing valve V, the piston rising over ports to vary the proportions of hot and cool water through the pipes reaching the valve V while keeping the combined volume constant. In winter the connection. between the reservoir of warmed water and the mixing valve V may be warmed, the plant then serving for air humidifying.

IPC: H04N1/04
Filed: 1997-01-08
Abstract: PROBLEM TO BE SOLVED: To realize image reading where image quality and productivity are balanced by setting an appropriate scan mode in accordance with an output print size. SOLUTION: The scan mode corresponding to the print size is registered for the respective types of originals in a scan mode registration screen 18a. The mode is set among the originals registered by switching the display of the original of a display column DI. A display column D2 shows the boundary printing size of the scan mode for the respective originals and it is set by a keyboard 22a. Display columns D3 and D4 show the scan modes less/more than a boundary value, an arrow is clicked and a setting value is changed. A display column Dd5 shows a registration list by individual print sizes showing the scanning modes corresponding to the print sizes. When 'registration by individual sizes' keys are indicated, the print size is selected, the scanning mode corresponding to it is selected and 'registration' is instructed, the setting value is updated and registration terminates.  Thus, a relation between the print size and the scanning mode can arbitrarily be set in accordance with the original type.

Title: Deuterium discharge tube and optical analyzing device
Inventor: FUKUDA TAKESHI
IPC: H01J61/68
Filed: 1994-01-11
Abstract: PURPOSE:To enable the use of a discharge tube with the simple structure in both ultraviolet area and visible area by providing a visible light emitting body in a space opposite to the light ejecting direction among spaces surrounded by electrode encloses divided by a small hole. CONSTITUTION:A small hole 3 for turning down the discharge is provided in a partitioning wall between a visible light emitting body 10, which also works as a positive electrode, and a light transmitting window 5. Arc discharge is started by a lighting circuit, and the visible light emitting body 10 is made to glow to a high temperature by a power source 19. As a result, a strong ultraviolet ray is generated by the discharge light emission of the deuterium gas in the hole 3, and the visible light is emitted by the heat radiation of the coil-like body 10, and these are collected together and radiated forward from the light transmitting window 5 through the hole 3. Consequently, a light emitting spectrum in a wide wavelength area over from the ultraviolet area to the visible area can be obtained. Since the visible light emitting body 10 also works as a positive electrode, structure inside of the electrode enclose 4 is simple, and the ultraviolet ray and the visible light can be efficiently emitted from the window 5.
