Patent GB-450307-A (GB)
Abstract: 450,307. Calculating-apparatus. EUROPA SCHREIBMASCHINEN AKT.- GES., and TOBIAS, W., 13, Mainzerhofplatz, Erfurt, Germany. Oct. 12, 1934, No. 29297. [Class 106 (i)] In a machine having a master actuating wheel mounted on a laterally movable carriage for selecting the denominations of the totalizer, the carriage supports a number of coupling members which connect together the transfer pinions to the left of the master wheel and align the numeral drums of the totalizer and effect the transfer by engaging the wheel of next higher denomination when driven by a transfer tooth on the transfer pinion operated by the master wheel. As shown in Figs. 1 to 3, the master wheel 1 gears with a transfer pinion 2 which actuates the corresponding numeral drum 3 through an intermediate pinion 4. Each transfer pinion 2 has integral therewith a transfer tooth 2a that co-operates with a pinion 5 broad enough to engage the teeth of the next higher transfer pinion. The master wheel 1 and the pinions 5 move together as they are supported in arms 7, 8 of a sliding carriage 6. The pinions 5 are held aligned by engagement of two of the teeth with a raised rim on the numeral drums and those to the left of the highest numeral drum are maintained in position by a stationary aligning bar 10. As the master wheel is moved to the -left an aligning bar 9 on the carriage engages the teeth of the transfer pinions 2 to the right of the master wheel to maintain their alignment. Each numeral drum is formed with a notch 3a, which at transfer, is engaged by a tooth of a pinion 5 at the moment that the transfer tooth 2a commences to drive the pinion 5.

Title: Fluid pressure regulators
IPC: F16K17/08
Filed: 1969-09-12
Abstract: 1,272,468. Valves. SIEMENS A.G. 12 Sept., 1969 [13 Sept., 1968], No. 45215/69. Heading F2V. In a fluid pressure regulator which has a supply line 9, 10, 11 terminating in a nozzle 12, flow to an outlet 15 is controlled by a hinged plate 19, the hinge being constituted by a portion of the plate which is of reduced thickness and which is disposed adjacent the plate anchorage point 16. In the fully-closed state of the valve, both the topmost face of the plate 19 and the periphery of nozzle 12 lie in the same plane C-D, thus providing a leak-proof closure of the flow path. The nozzle is disposed within, and opens into an inlet/outlet chamber 38 which under normal operation of the valve is in communication with a bellows B defining a further chamber 39. The topmost end 30 of the bellows B is subjected to the adjustable force of a spring 31 and has depending therefrom a spindle 2, with a portion of the spindle being disposed within chamber 39 and a portion being disposed, with clearance, within a passage 6 affording the communication between the two chambers. Formed at the free end of the spindle 2 is a projection 17 which, to a variable degree, is disposed within a port 18 formed in the plate 19 and which can engage a bi-metallic strip 37 secured in spaced relationship to the plate 19. In operation, a reduction in pressure within chamber 39 results in the spindle moving downwardly and hence in plate 19 being displaced from the terminal end of nozzle 12 so increasing the degree of communication between the inlet leading to, and the outlet leading from chamber 38. In the event of the valve being subjected to a temperature increase and hence the spring 31 becoming softened, the bi-metallic strip bends towards the plate 19 and so, in conjunction with the spindle terminal portion 17, acts as a compensator which nullifies any changes in the characteristics of spring 31 and so also ensures proper positioning of the plate 19 under varying pressure conditions.

The tag terminal (Fig. 5, not printed) is of planar configuration and is barbed along each edge to ensure retention at a push fit within a socket 20. Each bore 19 and adjacent socket 20 is formed in a boss 14, 16, 17, 18 projecting at each corner from the outer face of the flange, beyond a bounding peripheral wall 13 thereof. When moulded integrally with a tubular bobbin core, an end portion 15 of the core projects from the outer face of the flange to the extent of the wall 13, and is surrounded by a shoulder 42 which functions as a ring gate during moulding, and from which the moulding material is outwardly distributed along projecting rib formations 41 of the flange. The bores 19 each open into a recess 34, 36, 37, 38 in the inner face of the flange, and a guide channel 35 for a wire extends in the inner flange face tangentially from the tubular core into one of the recesses 34. The walls 32 of the recesses define rounded edges around which the wires pass to avoid sharp bending and severing contact of the wires with the sharp edge around the outlets of the bores 19, which are defined during moulding by core pins carried by a moulding die. The bobbin may be moulded with a circular flange at its other end, which is slightly concave on its exterior face and with a tapering inner face to facilitate mould opening. The flanged bobbin is moulded within a three part die comprising one part defining the outer face of the flange having the sockets and bores, and which is separable longitudinally of the tubular core, and a pair of dies which define the remainder of the bobbin and which are separable longitudinally of the channel 35.
