Title: Improvements in or relating to devices for use in controlling the speed during braking of vehicles, particularly, although not essentially, railway vehicles
IPC: F16D66/00
Filed: 1936-03-12
Abstract: 477,021. Brakes ; train-control apparatus. VEREINIGTE EISENBAHN-SIGNALWERKE GES. March 12, 1936, No. 7512. Void. Convention date, March 23, 1935. [Class 103 (i)] [Also in Groups XIX and XXX] In a device for use in controlling the speed of railway and other vehicles during braking, which includes a cam-actuated member operable during braking to afford a comparison between the actual speed and a prescribed progressively decreasing limiting speed, the transmission ratio between the cam and the member is adjustable for different initial speeds and the initial setting of the cam may also be adjustable according to the distance in which the vehicle is to be brought to rest. Fig. 1 shows speed variation curves to be followed for bringing the vehicle to rest in the distance y, o from different initial speeds measured along the axis y, x. A cam 8 moves a pointer 5 through a lever 10 pivoted at 11 and a rack 7 geared to the spindle of the pointer which traverses the scale 4 of a tachometer having a pointer 3 which indicates the actual vehicle speed. The cam 8 is coupled to an axle of the vehicle at the commencement of the braking operation and its form is such that the pointer 5 indicates the speed to be observed, corresponding to one or other of the curves shown in Fig. 1. Instead of the pointer 5, a contact may be provided which is actuated to apply the brakes when the actual speed exceeds the prescribed speed. For selecting the particular curve according to the initial speed, the pivot 11 is displaceable to vary the arms of the lever, in a guide which is parallel to arrow 13 the direction of which is such that while the initial position of the pointer 5 is altered by displacing the pivot, the pointer reaches the scale division O at the end of the travel of the cam irrespective of the position of the pivot. It may also be necessary to adjust the drive for different distances in which the vehicle is to be brought to rest and for this purpose the initial angular position of the cam on its driving spindle is rendered adjustable as shown in Fig. 3. The cam is secured to a spindle 16 which passes through the driving spindle 15 and is coupled to it by a claw coupling 14 normally held engaged by a spring 17. Depression of a knob 18 couples it to the spindle 16 and disengages the coupling 14 and by then turning the knob the angular setting of the cam may be varied. The adjustment is indicated by a scale and pointer 20, 21 secured respectively to the spindles 15, 16. The device instead of being operative for a particular distance of vehicle travel may be operative over a given time interval.

Title: Improvements in or relating to radio receiving circuit arrangements
IPC: H03G3/30
Filed: 1959-03-05
Abstract: 844,043. Radio receiving circuits; transistor receiving circuits. PHILIPS ELECTRICAL INDUSTRIES Ltd. March 5, 1959 [March 8, 1958], No. 7689/59. Classes 40(5) and 40(6). A radio receiver comprises a transistor frequency-changer 1 coupled by I.F. transformer 5 to transistor I.F. amplifier 2, which also functions as the local oscillator, the collector and emitter being back-coupled via circuit 3 tuned to the local oscillator frequency. A gain control voltage is applied to the base of transistor 2 from terminal 7, which produces an amplified voltage across resistor 8 in the collector circuit. This is used to vary the impedance of a diode 4, acting as a non-linear resistor, over which the local oscillator voltage is applied to the emitter circuit 9 of the frequency-changer 1, and so enhances the variation in gain. The arrangement may also be used with thermionic valves, in which case the diode 4 is replaced by a non- linear resistor of the ceramic type.

Filed: 1943-05-21
Abstract: 566,518. Moulding artificial teeth. HALLIWELL, F. May 21, 1943, No. 8090. [Class 87 (ii)] [Also in Group VI] An artificial tooth which resembles a natural tooth is made by first moulding a portion D, Figs. 5 and 6, which has ridges and indentations on its surface, and then moulding on the portion D, in the same mould but using a different die, a second portion E, of translucent material of a lighter colour than the portion D, the darker under-layer D being visible in the finished tooth to a greater or less degree, depending upon the depth to which it is submerged in the lighter material. Faults or discolorations are thereby simulated. The incisal edge e may be made wholly of the translucent material. The teeth may be moulded twelve at a time by using three mould blocks A, B, C ; first the portions D are press-moulded between the blocks A and B, then the block B is removed, leaving the portions D in the block A, and finally the portions E are press-moulded between the blocks A and C (the mould recesses in the block C being larger than those in the block A). In a modified method, Figs. 7, 8, 9 (not shown), the teeth are injection-moulded in three blocks similar to those shown, the injection channel in the block C being of greater diameter than the injection channel in the block B.

A system for controlling the mixing of two gaseous or liquid streams A, B to produce a mixed stream C of predetermined quality comprises, a meter 2 sensing a property of the stream C, a controller 3 which compares the signal from meter 2 with a set value and provides an output which is fed to multiplier 4 which in turn provides an output representative of the product of the output of controller 3 and that of a flowmeter 1 sensing the flow rate of stream C, and a ratio controller 5 which compares the ratio of signals from a flowmeter 6 and the multiplier 4 with a set value and controls the flow of stream A and/or B. The sensed property of stream C might be viscosity, temperature, octane number, vapour pressure or flash point. It is shown that the gain of the system is independent of the flow rates. If the flow rate of one of the streams A, B is considerably, larger than the other, then flowmeter 1 may be replaced by a meter sensing the larger flow, whilst controller 5 receives a signal from a flow meter in the other stream. A function generator (9) can be installed between meter 2 and controller 3. One or both of the streams A, B may be a mixed stream produced as above or by other methods.
