Title: Suspension means for vehicles
IPC: B62B9/18
Filed: 1945-05-30
Abstract: 592,772. Vehicle spring-suspensions. HUDLASS, L May 30, 1945, No. 13548. [Class 108 (ii)] Relates to spring-suspensions for baby or invalid carriages, ambulances &c. of the type in which each wheel is carried by an arm pivotally secured to.. the vehicle so that it can rock away. from its normal. substantially horizontal position against the action of spring means. According to the invention, the arm is formed with or is secured to a shaft having a threaded and rotatable engagement with a member fixed to the vehicle to provide the pivotal connection for the arm. As shown in Fig. 1, each wheel 10 of a baby-carriage is. mounted on a stub-axle 9 on a cranked extension 8 of a shaft 6 or 7, the inner end of which has a screwthread engagement with a plug 4, Fig. 2, fixed in a tubular member 3 forming one end of a rectangular frame 1 to which the body of the carriage is rigidly attached. Lugs 11 on the extensions 8 on each side of the carriage are connected by a spring 13. The frame 1 may be dispensed with and each tube 3 directly connected to the body by lugs, or, as shown in Fig. 5, by a flange 15 at one end and a collar 16 threadedly engaging the tube at the other end, each cranked arm in the latter case having an. extension 18 for connection to the spring. The spring 13 may be replaced by a pair of compression springs housed in a common tube and each acting between one end of the tube and a piston on a rod coupled'to the adjacent crank arm, or each crank arm may be connected, to piston-and-cylinder form of air cushion.

Title: Process for the manufacture of binders for use in the production of carbonaceous electrodes
IPC: C25C3/12
Filed: 1959-04-21
Abstract: Carbonaceous electrodes are prepared with the aid of a binder obtained by grinding pitch (or like carbonaceous material), having a softening point above 100 DEG  C., to a powder of such a degree of fineness that at least 70% of the powder consists of particles which pass through a 200 mesh Tyler screen.  The powdered pitch may be mixed with the dry components (coke, anthracite or graphite) of the electrode composition, preferably initially at room temperature, although heat may be applied during mixing after an initial cold-mixing.  In an example, pitch of 155 DEG  C. softening point is wet-ground in a ball mill until 70% of the pitch will pass through a 200 mesh Tyler screen.  Surplus water is removed by filtration, using a vacuum filter, and the paste is blended with petroleum coke.  After pre-heating the mixture at 90 DEG  C. for 24 hours and at 320 DEG  C. for 48 hours, the composition is baked at a temperature rising to 1000 DEG  C. in the course of 57 1/2 hours. The electrodes are suitable for use in metallurgical processes, such as the production of aluminium by electrolysis.

The rolls are driven through universal &c. joints from intergeared shafts mounted in a separate stationary driving box. A pit 6 is provided to receive scale &c. The motion of the ram 8, Fig. 5, is also applied to actuate through links 35, 34, a series of wheeled carriages 30 mounted on rails under the feed tables and parallel to the roll axes. These carriages are provided with uprights carrying guide bars 33 and operate in such a manner as to transfer the work laterally through a distance substantially equal to the space between the guide bars, at each reciprocation of the ram 8. The carriages are also provided with vertical plungers 40, Fig. 6, connected by bell-cranks 42 to horizontal bars 44 pivoted to a stationary part of the mill, the plungers rising at each reciprocation of the carriage so as to invert the work-bars.

Abstract: 812,514. Testing hardness of materials. ARTHUIS, A. R. April 30, 1957 [May 11, 1956], No. 13710/57. Class 106 (2). Apparatus for determining the surface hardness inside hollow cylindrical bodies comprises two instruments 1, 14 interconnected by flexible tubing, namely a penetrator carrier 1 which can be moved independently and an instrument for generating the hydraulic pressure required to produce the impression of the penetrator 3, and for hydropneumatically indicating the depth of penetration. The penetrator carrier, Figs. 1 and 2, consists of a cylinder 1 supported by a cradle 10, which may be replaced by others of differing sizes, the cylinder 1 having a piston 2 and indentor 3 sliding in a radial bore. The piston 2 acts on one end of a lever 8, the opposite end of which acts on a metallic bellows 6. The pressure generator and indicator is shown in Fig. 4. A plunger 15, actuated by a handle 17 acts on oil in a duct 18, communicating with a bore 5 in the cylinder 1 by means of a flexible tube 12. This duct 18 also communicates with the interior of a cylinder 20, in which the pressure of the oil acts on a plunger 19, which, together with a weight 21, forms the minor load for a Rockwell test. Further inward movement of the plunger 15 causes the plunger 19 to pick up a second weight 22 to form the total load for the test. A cylinder 23 contains liquid and the upper surface is in communication with the interior of the bellows 6 by means of a flexible tube 13, indication of the degree of compression of the bellows 6 being given by the level of liquid in a capillary tube 30. The cradle may be replaced by an arrangement of mechanical or hydraulic jacks.

Title: Improvements in or relating to waveform generating circuit arrangements

Abstract: 917,311. Triangular sine wave generating circuits. PHILIPS ELECTRICAL INDUSTRIES Ltd. April 23, 1959 [April 26, 1958], No. 13875/59. Class 40 (6). [Also in Group XXXVI] A waveform generating circuit for an output voltage which is a predetermined function of an input voltage comprises a limiting difference amplifier producing a constant output voltage whenever one of its input voltages exceeds the other in amplitude, receiving a first voltage on a first electrode and a second periodicallyvarying voltage on a second electrode; the first input varying, e.g. sinusoidally at a frequency considerably lower than the second input but having the same amplitude and the integrated output voltage of the limiting difference amplifier being an alternating voltage of e.g. triangular waveform. A voltage V 1  is applied to the grid of triode 3 (Fig. 1), and a periodic voltage V 2  of suitable waveform to the grid of triode 4 of a difference amplifier; both triodes having a common cathode resistor 7 and individual anode resistances 5, 6 producing current pulses, having duration equal to the time of excess of one voltage over the other and varying inversely as the time function of the periodic voltage, which are amplified at 8, limited at 9 and integrated at 10 for measurement at M as a desired function V u  = f inv (V 1 ) when V 2  varies as a function of time f(t). Voltage V 2  may be sinusoidal of maximum value V r  so that bT is the duration of a cycle, and t 0  the time of the first quarter cycle for which V 2  exceeds V 1 , the output voltage V 1  varies as arc sin - (Figs. 2 (a), (b)). If the V, amplitude of V 2  varies cyclically as an increasing exponential function of time the output voltage measurable at 11 varies as the log of input voltage. If V 2  is a saw-tooth voltage of constant frequency linear with time, the output voltage varies directly as the first input voltage. The latter may be alternating of frequency considerably lower than the periodic voltage V 2 , and if sinusoidal (Fig. 3 (b)) with a sinusoidal voltage (Fig. 3 (a)) of higher frequency at the remaining input, the output voltage is shown to vary triangularly at the period of the first input voltage (Fig. 3 (c)). A low-frequency sinusoidal waveform may be generated from a similar frequency triangular waveform (Fig. 5) by applying a sinusoidal voltage of e.g. 5,000 c.p.s. to an input of a limiting difference amplifier I followed by an integrator II as in Fig. 1, whose output is connected to a first input of comparison device III; the second input of which receives the output of a triangular waveform generator 31 controlled by a trigger device 34 connected to the first input of III. The outputs of III are connected to the inputs of a difference amplifier IV whose second output feeds a cathode follower amplifier V whose output develops a sinusoidal voltage at the frequency of the triangular waveform which is fed back to the other input of I.
