Title: Fluid proportioning device
Inventor: VOGELMANN ERNST
IPC: G05D11/00
Filed: 1969-05-13
Abstract: 1,214,237. Mixing flowing fluids proportionally. E. VOGELMANN [trading as CILLICHEMIE ERNST VOGELMANN], 13 May, 1969 [17 May, 1968], No. 24280/69. Heading B1C. In apparatus for proportionately adding a solution to a liquid flowing in a conduit 1, the pressure-difference across a restriction 2 causes part of the flow to be by-passed through a conduit 4 into a bellows 7 the apertured base 8 of which rests on solute 9. The solution returns to conduit 1 through throttle valve 10, chamber 30, opening 26, and conduit 5, the pressuredifference across the restriction being applied also to diaphragm 14 which by means of pin 15 opens check valve 11 so long as there is flow in the conduit 1. If valve 28 be closed to stop flow in conduit 1, valve 11 also closes, to prevent outflow of additive caused by casual pressure fluctuations in conduit 1, especially if there be air in the tank 3. In a modification, (see Fig. 2, not shown) pressure in the conduit 4 is transmitted to diaphragm 14 through a dashpot device, comprising a second diaphragm (19) and a chamber (186) thereunder communicating with a chamber (17) above diaphragm 14 by means of an aperture (20); the two chambers are filled with a viscous liquid so that a time lag dependant on the viscosity is imposed on the operation of pin 15, whereby large but brief pressure fluctuations in conduit 1 fail to open valve 11. An additional relief valve (21) in the conduit 4 may be provided. The restriction 2 may consist of an annular element 2a, Fig. 3, and a disk 22 attached thereto by a resilient tab 31; at low velocity the fluid flows only through the annular space 32 whereby an effective pressure difference is maintained.

Wheels. - A vehicle wheel hub shell for attachment to a rim by wire spokes is formed in two parts, a barrel part 7 and flange part 8 which are subsequently united by ordinary welding, the barrel blank being cut and cupped from strip metal 34, Fig. 4, the cup being then elongated in the dies and then bulged out to shape 11, Fig. 7, by internal fluid pressure 12. A punch 44, Fig. 7, also shears the bottom of the cup but not quite through, so that the pressure oil is retained until poured out, after which severance is made. The hub flange is sheared from strip 47, Fig. 8, and shaped and the centre is punched out as shown. The edge of the centre hole is machined to prevent cracking when subsequently flanged as in Fig. 9, in which dies form an outer annular rib 24 with spaced elongated bosses 22, radial ribs 21<1> and circular depressions 25. The blank is then restruck in dies, Fig. 10, the bottom of the circular depressions &c. punched out by punch 57 and the outer edge of the blank &c. trimmed off by shearing. The two blanks are then welded, the weld being machined off and the whole hub is restruck in dies, Fig. 11. The hub is then clamped in a lathe, Fig. 12, where the external weld marks are removed, the internal ring face 16 is turned up and the hole in the hub is also turned up. A punch 63, with work holder 62, locating pilots 65, Fig. 13, and with indexing mechanism, forms the spoke holes in the outer flange, countersinking them from the inner side to form spoke seats 23 in the arcuate walls of the bosses 22 in the annulus 20.

Filed: 1927-09-19
Abstract: 302,636. Callow, A. M. Sept. 19, 1927. Metals, depositing; moulds; preparing surfaces. -A metal panel having an inlaid design of non- metallic material is made by securing the inlaid devices to a temporary backing by an adhesive applied around the edges only, so that the devices are in contact with the backing over substantially the whole of their surface, then applying an electrically conductive coating to the edges, and finally depositing metal electrolytically on to the exposed part of the backing and over the edges of the inlays. The inlaid devices remain integral with the deposited metal layer on removal of the latter from the backing. The are locked by a slight " creeping " of the deposit over the edge. The edges of the inlays are preferably undercut so that they cannot be displaced through the front of the panel. When the inlays are large and of shrinkable material such as celluloid they are provided with short pins secured in holes drilled in the edges. These are covered with conductive material and are enveloped in the subsequent metal deposit. The foundation plate may be of silver-plated copper or other material covered with lead. Acetone or amyl acetate may be used as adhesive for the celluloid inlays.

Abstract: 999,434. Analysis of radio-active substances. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. July 9, 1962, [July 7, 1961], No. 24693/61. Drawings to Specification. Heading G1A. [Also in Division H3] Apparatus for measuring the proportion of an ingredient in a mixture comprises means for generating electric pulses with a recurrence rate dependent on the amount of the ingredient and further pulses with a recurrence rate dependent on the amount of the remaining material in the mixture and applying the first pulses to a counter counting down from a maximum count. The counting is stopped when the two counters show equal values and the proportion can then be derived. Thus if the maximum count is 1, 000 the amount of the ingredient in a 1, 000 units of the mixture is indicated. In determining the amount of U 235  in a mixture of U 235  and U 238 , α particles from the mixture are allowed to fall on a semi-conductor junction to which reverse bias is applied. Pulse height analysis of the resulting pulse train enables pulses due to 4.18 Mev particles from U 238  to be sorted from those due to higher energy particles from U 235 . The separated pulse trains are applied to counters in the manner referred above and upon co-incidence of count, detected by a co-incidence of circuit, a gate is closed preventing the flow of further pulses. The count may be recorded. The quantities may not give rise to pulses themselves in which case they are used to control the recurrence frequencies of pulse generators each as oscillators followed by squaring and differentating circuits.

Filed: 1972-05-26
Abstract: 1359783 Toothed gearing MOTOROLA Inc 26 May 1972 [28 June 1971] 25000/72 Heading  F2Q [Also in Division H3] In a radio receiver including automatic tuning a first gear 66, Fig. 5, is mounted on a rotatable drive shaft 36 which is connected to tuning apparatus 32 (Fig. 2, not shown), a second gear 68 is provided for coupling a drive motor 86, Fig. 3, to the first gear 66 and linking apparatus 92, 104, Fig. 4, is movable from a first position to a second position in response to actuation of a solenoid 124 to place the first and second gears 66, 68 in meshing engagement so as to couple the drive motor 86 to the drive shaft 36 for altering the frequency setting of the radio receiver. A manual tuning knob 20 is coupled by a gear 56 to a third gear 40 which is mounted on the drive shaft 36 and the linking apparatus 104, 48 decouples the third gear 40 from the drive shaft 36 to prevent rotation of the manual tuning knob on operation of the solenoid 124 during automatic tuning of the radio. To start automatic or search tuning a bar (30, Fig. 1, not shown) is pressed, this actuates a trigger circuit (133, Fig. 6, not shown) and a relay (138) which energizes the solenoid 124, the motor 86 and a coil 83. The coil 83 causes a pawl 82 to engage a gear-wheel 85 so that the motor 86 is coupled to a drive shaft 70. The actuation of solenoid 124 causes clockwise movement of a plate 104 about a pivot 114. This moves declutching bar 48 to the left so as to disengage clutch 60, 62 to decouple the manual tuning knob 20 from the tuning drive shaft 36. Also when the solenoid 124 is actuated lever 96 is moved in an anticlockwise direction to move the gear-wheel 68 into mesh with a crown wheel 66 which is coupled to the tuning shaft for driving the core type tuning carriage assembly (32) from the motor driven shaft 70. When a new frequency setting is reached the relay (138) is de-energized by the trigger circuit (133) so as to de-energize the solenoid 124 and pawl solenoid 83. Disengagement of the pawl 82 with the gear-wheel 85 stops the drive from the motor to the shaft 70 and dropping out of the solenoid 124 re-engages the clutch 60, 62 so as to couple the manual tuning knob 20 via a universal coupling 52 and gears 56, 40 and the clutch 60, 62 to the tuning shaft 36. During motor drive tuning a cam 130 actuates a switch 132 at the ends of the tuning range so as to reverse the motor. The radio also has a tuning dial (26), an indicator (24) five push buttons (18) for preselected frequency settings and an AM-FM band switch (28).
