Abstract: 439,920. Thermally-actuated valves. CASE, W. G., 66, The Ridgeway, Kenton, Middlesex. Dec. 27, 1934, No. 37100. Convention date, Dec. 28, 1933. [Class 135] [See also Groups XXXVIII, XII, and XIII] For regulating temperatures of thermic apparatus, such as the heating- apparatus of a building or refrigerating-apparatus, in accordance with external temperature conditions, the operation of the thermic apparatus is modified by a temperature sensitive device heated to a predetermined temperature and subjected to the external temperature. As shown the thermostatic apparatus subjected to the outside temperature comprises a thermostat A which is maintained at constant temperature under the action of a heating resistance B and an interrupter switch E<1> controlled by the thermostat through levers C. The heater circuit is interrupted continuously to maintain a constant temperature level, the amount of heat supplied depending upon external conditions. The heater H of a second thermostat G arranged to control the heating plant, is connected in series or parallel with the primary heater B and therefore is controlled in correspondence with the outside temperature and modifies the action of the heating system, e.g. by the control of the draught door of a boiler. In the arrangement shown, the thermostat G effects the control through a lever I which also is controlled by the thermostat F located in the boiler for effecting the normal regulation. A spring J may be provided on thermostat F in order to prevent damage to the expansible bellows of the thermostat due to mechanical shocks on the lever I. If the lever I is moved violently the collar F<3> is moved out of engagement with the nipple F<4> without imparting movement to the bellows. A similar arrangement may be provided in the thermostat G. The heaters B, H may be replaced by gas burners the supply to which is controlled by the thermostat A.

Title: A machine for perforating and combining several webs of paper or like sheet material
IPC: B31B170/20
Filed: 1963-09-24
Abstract: 1,057,676. Perforating bag tubes; perforating apparatus. A WINDMÍLLER, and M. GENNERICH, [trading as WINDMÍLLER & HÍLSCHER]. Sept. 24, 1963 [Sept. 24, 1962], Headings B4B and B5D. [Also in Division F2] A set of webs (7) ... (12) (Fig. 1, not shown) are perforated at (19), receive a transverse glue stripe at. (20), and are combined over a single roller (26). The lengths of web between the perforators (13) . . . (18) and the applicators differ, and the rotary perforators (13) ... (18) are driven through clutches which permit their phasing to be varied independently. In the embodiment described, each perforator shaft (27) (Fig. 3, not shown) is driven by a cone clutch (34) which can be disengaged from its driving gear (33), by releasing a nut (46), and may then be turned by a hand wheel (42) fitted with a pointer (44). The driving gears (33) are coupled by gears (36) (Fig. 2, not shown) so that they may all be driven from a single bevel input (29), (30) (Fig. 3). Each of the gears (36) may be slid axially, to disconnect the drive to the perforators above it, by a hand wheel (59) operating a lead screw (60). To alter the spacings between the perforations the speed of the webs may be altered without altering the mean speed of the perforators: the perforators are then caused to perform a non-uniform motion so that the perforating blade is travelling at the same speed as the web at the moment of perforation. This effect is provided by a slider crank mechanism (37), (35) and (50), (51) (Fig. 3) between the cone clutch (34) and the shaft (27): the cranks (48), (49) are carried by shafts (47) supported on rods (54), (55) so that they can all be moved simultaneously out of the normal position in which the shaft (47) is aligned with the shafts (39) and (27). The spacing of the perforations may be doubled in an alternative embodiment (Figs. 4 to 6, not shown) in which the shafts carrying the perforator knives are lifted from the web at each alternate revolution by a cam (66) driven at half the speed of the perforator shaft (27) through gearing (62), (69), (68).

Abstract: 1395936 Reactors SIEMENS AG 11 Aug 1972 [11 Aug 1971] 37664/72 Heading G6C In a nuclear reactor, the elongate fuel elements are mounted between upper and lower support grids with stressed resilient means arranged to be effective between one of the grids and the adjacent end of each fuel element so as to maintain the other end of each fuel element pressed against the other of the grids. Reactor coolant passes through the fuel elements in the direction from the one grid to the other. The spring pressure is thus assisted by the coolant flow, so that vertical oscillation of the fuel elements is avoided. In one particular embodiment (Fig. 7), force transmission is effected by springs 71 guided on pins 73, via a flange 75 on a central tube 76, the upper edge of which presses against the base of a fuel element 5. The pins 73 depend from a plate 6 provided with centring pins 9 establishing a connection between the lower grid plate 4 and the fuel element base. The tube 76 slides in a bore formed in the plate 6 and is additionally guided by a lower flange 77  formed with bores for the pins 73. The coolant flows upward through the tube 76 and the coolant throughflow can be varied either by selecting a tube of appropriate cross-section or by the installation in the tube of a throttle device.
