IPC: B28B1/48
Filed: 1928-02-09
Abstract: 307,182. Coulter, W., and Burslem Productions, Ltd. Feb. 9, 1928. Stationary-mould machines; pressing-dies.- Perforated cup-shaped articles of pottery, e.g. coffee strainers, are formed by pressing- mechanism involving a. series of pins &c. slidably associated with the male die and actuated by link mechanism co-operating with a stop on the female die which advances the pins relatively to the associated die during the actual pressing operation. As shown, the male die a is furnished with pins a<3> attached to a head a<4> which is connected by a link a<6> to a lever a<7> having its end a<8> normally depressed by a spring a'. The female die b is fixed and is fitted with a loose bottom b<1> apertured at b<3> in alignment with the pins and adapted to be raised' by rods b<2> to eject the moulded article. In operation, the die a is raised as shown and the mould is charged with clay dust. Upon descent of the die a to shape the article, the pins a<3> are advanced through the material by a stop b<4> on the die b engaging the end a<8> of the lever a'. In place of the spring a<9>, the lever a' may extend beyond the rod a<6> and be furnished with a cushioning-device adapted to engage the top of the die b. According to the Provisional Specification, the pins may be associated with the bottom die and be actuated bv the descent of the upper die.

Title: A device for connecting mechanically parts of the electrical installation for a motor vehicle
IPC: B60R16/00
Filed: 1953-02-13
Abstract: 720,705. Switching systems. BARRIONUEVO, A. R. Feb. 13, 1953, No. 4086/53. Drawings to Specification. Class 38 (4). [Also in Group XXXVII] To avoid the necessity of unduly long conductors in the electrical installation of a motor vehicle, consequent upon the use of a single multiple-position dashboard switch, the switch is subdivided into two units, one of which is retained adjacent the dashboard and the other located in the forward region of the car, the two units being ganged together for common control by a single actuator on the dashboard and the switching of each individual circuit being effected at that unit which is nearer to the circuit. Thus, the head-lamps may be switched from the forward unit, whilst a tell-tale dashboard lamp operating in conjunction with the head-lamps may be switched by the dashboard unit-as may also be the rear lamp. The dashboard unit may also carry contacts for controlling the engine starter motor, these contacts being brought into engagement by axial movement of the switch actuator. The ganging of the two units may be rods provided with universal couplings.

A thermostatic mixing valve for mixing water and steam has a regulating chamber 10 with a bore which tapers oppositely from each end to its central region and contains a complementary shaped valve head 15 of smaller dimensions so as to provide two axially-spaced ring-like passage-ways between the head and the bore to which communicate ducts forming fluid inlets and outlets, the head being supported freely in and in coaxial aligned relation with the bore to reduce frictional restraint to movement imparted to the head by thermal means, e.g. the bi-metal coils 44, 45 in the mixing chamber 13 to vary the area of the passage-ways simultaneously and differentially, one of the tapered portions of the valve head mating with its associated tapering bore to effect a complete closure of the passage-way in an extreme position of the valve. The head screws on a high pitch thread 42 on a spindle 38 which can be moved axially by means of the screwed ends 53 engaging a setting handle 16, 55, splines 40 preventing rotation of the spindle. The coil 44 is secured through a sleeve 46 to the splines and the coil 45 secured through a sleeve 47 and pins 49 to the valve head, so that rotation of the valve moves it axially to control the flow of steam from the inlet 21 through the passageway 30 and of water from the inlet 23 to the passageways 31 and 28.

Filed: 1966-02-03
Abstract: <PICT:1088013/C6-C7/1> <PICT:1088013/C6-C7/2> An electrolytic grinding wheel comprises at least two different grinding sections, one of which is electrically conductive and the other of which is electrically non-conductive or insulated.  As shown, for side-grinding a workpiece 6 to which an electrolytic solution 9 is supplied, conducting sections 1, 1' are mounted one each side of a non-conducting section 2 on a shaft 3 made of conducting material. With this apparatus, electrolytic rough grinding can be followed by mechanical finish grinding by breaking the electrical circuit with a switch 4.  The grinding wheel may be assembled on a metal support 15 and constructed of diamond layers 12, 12' mounted on metal spacers 16, 16' and a diamond layer 14 mounted on plastic spacers 13.  Fig. 5 (not shown), illustrates diamond layers (12, 12', 13) assembled concentrically on a metal cup-shaped support of a face-grinder.  Fig. 6 (not shown), illustrates a side-grinding wheel in which non-conducting sections (2, 2') are mounted one each side of a conducting section (1) on a shaft (3) to avoid the electrolysis effect on the edge of the workpiece (6).  In this embodiment, plastic spacers (13, 13') Fig. 7 (not shown) are provided with projections for locking purposes. The abrasive substance may be in a plastic matrix in the non-conductive section but when a metal matrix is used the sections must be insulated from one another with for example plastic inserts, 20, Fig. 8 (not shown).  The grinding sections may be in the form of strip-segments mounted either longitudinally, Fig. 9 (not shown), or helically, Fig. 10 (not shown) around a cylindrical support; alternatively, the segments may be mounted radially on a face-grinder, Figs. 11, 11a (not shown).  The non-conducting or insulated sections may have a higher concentration of abrasive substances, a larger grain size or a grinding area larger than that of the conducting or insulated sections; alternatively, diamonds may be employed in the non-conducting or insulated sections and corundum in the conducting sections.
