Title: Apparatus for determining the angular axial relationship of the axes of vehicle wheels
Filed: 1947-07-17
Abstract: 635,925. Gauging alignment of vehicle wheels. FRIESTEDT, A. A. July 17, 1947, No. 19153. Convention date, April 24, 1940. [Class 106 (ii)] Apparatus for checking the angular relationship between a pair of axles, such as the wheel axles of a motor vehicle, comprises a base 9 (not shown), to be secured to a wheel 7 on the rear axle, an arm 11 adjustably mounted on the base and carrying a groove disc 10 to which is secured one end of a line or cord 13, a stand 14 carrying a pointer 20, and a second stand 15 over which the free weighted or spring- tensioned end of the cord is passed. There are also a pair of turntables 22 for the front wheels, and a measuring rod 24. In use, each front wheel is raised and rotated with the pointer 20 in contact with the periphery of the tyre, whereby a circular mark 27 is made on the tyre, the wheels then lowered on to the turntables, and transverse marks 28 then made on the tyres at the same height as the cord 13. The wheel 7 is raised so that it just frictionally engages the floor, and turned to bring the arm 11 into the dotted line position. The stand 14 is moved to position the pointer 20 so that it touches the cord 13 in the disc 10, the wheel rotated so that the arm 11 is in the full line position with the disc 10 at the same height as before, and the forward end of the cord adjusted so that the pointer 20 is just touching. The cord 13 thus extends perpendicular to the rear axle and is used as a basis for the adjustment of the front axle. The front wheels are rendered independently adjustable, and measurements made from the cord to the marks 27, 28 on the rear tyre. The rod 24, which is used to check the distances between the front wheels, has a brad 25 which.is pushed into the tyre 5 at the intersection of the marks 27, 28. The stand 15 may be pivotally mounted in a box 16 in which all the apparatus, except the rod 24, may be packed.

Title: Improvements in bituminous concrete pavements and processes for making the same
IPC: E01C23/06
Filed: 1918-11-21
Abstract: 141,769. Henderson, G. A. Nov. 21, 1918. Macadamized roads; cauldrons.-A bituminous composition prepared by the process set forth below and consisting of bitumen, dust, and fine aggregate such as stone or wood particles, is laid on a scarified macadam road or is moulded into paving- blocks. The mixing is effected in the apparatus shown in the Figure, such apparatus being hauled by a motor-driven bitumen-heating tank. The loosened road aggregate is heated in situ by oil burners d<1> and again scarified by centre tines b. Dust is removed by suction through flues f<2> which penetrate a bitumen-heating tank k and converge to the rear end of a drum l. The tank is heated by the waste heat from the burners. A suction fan C<1> ejects the burner gases and steam from the drum to the atmosphere, and the dust from the flues f<2> passes to a chamber f<3> where it is mixed with a predetermined quantity of other dust supplied from a hopper f<4>; the dust mixture then passes through the bitumen drum l, where it is intimately mixed with the bitumen sprayed by blades l<1>. The bitumen is further circulated by a pump o through pipes n, n<2> to the reverse side of the tank, and a portion of the bitumen is supplied by a hand' valve n<3> to a weighing-bucket n<4> mounted on a weigh beam n<5>, whence it is discharged into a pug mixer L. At the same time there is also discharged into the pug mixer from a weighing-bucket w<2> a quantity of clean, small stone or wood chips which have been partially dried so that they contain from 10 to 15 per cent of residual moisture: this smaller aggregate is led from a hopper w. Two sets of pug mixers and weighing-buckets are provided and act alternately to maintain a continuous supply to the drum l. The contents of the drum are forced by the blades l<1> through a gate valve l<4>, and are deposited either on the road or into moulds to be formed into blocks as described in Specification 8341/12, [Class 34 (ii), Drying systems &c.]. Bitumen is sprayed on the dustless road by nozzles g<1>, the surface is turned by tines a<8>, and then receives the contents from the drum. The road is finally rolled while still hot. The new materials may also be laid on a compact base or foundation in one or more layers, the base and each layer being painted with bitumen to ensure a bond. Power is taken from the rear axle S<2> to drive the shaft m and valves f<5>, l<4>.

Title: Pulse generating oscillator circuit
IPC: H03K3/57
Filed: 1969-04-16
Abstract: 1,255,744. Transistor oscillators; pulse generators. BENDIX CORP. 16 April, 1969 [24 April, 1968], No. 19324/69. Addition to 1,255,542. Headings H3P and H3T. [Also in Divisions F1 and H2] A pulse generator has the collector-emitter path of a transistor 11 in series with the primary 15 of a three-winding transformer 16 whose tertiary 37 is connected between the base of T11 and the collector of a transistor T24 connected across the supply, wherein the power input to the generator is maintained constant by the T24 base bias circuit including a Zener 32, a diode 33, a resistor 34 and a diode 31, there being also a diode 39 between T11 base and earth. Transistor 11 has a second transistor 11<SP>1</SP> in parallel with it, ahd the diode 39 protects their e-b junctions. The base bias circuit of T11 includes a starting resistor 26, and during oscillation the voltage across the tertiary winding causes base current for T11, 11<SP>1</SP> to be drawn through a resistor 27 and transistor 24. The resistor 27 is adjustable to set the desired current in T11, 11<SP>1</SP> and hence output power, and the degree of conductivity of T24 is varied by the supply voltage applied through the Zener diode 32 and the diode 33. The Zener voltage is chosen to equal the minimum supply voltage, and increase in the latter causes the base voltage of T24 to go more positive to reduce its current. The load circuit fed from diode 41 includes a tank capacitor 42 whose voltage when reaching a certain level causes a spark gap 43 to break down and discharge C42, thereby applying a pulse to an induction coil 45, and through a load-splitting transformer 44 to a second induction coil 45<SP>1</SP>. The coils supply spark gaps 46, 46<SP>1</SP> in an i.c. engine, and the coils have associated capacitors connected as shown. A pulse suppression filter 20, 21, 23 is connected in the supply line to the oscillator.

In an addressing machine in which printing plates are delivered from a magazine 3, Fig. 1, fed along two parallel downwardly elastically yieldable guide rails 6 to a collection magazine 4, the printing pad 17 is mounted on a vertically displaceable elastically yieldable printing ram 1. The ram 1 comprises two telescopically interfitting tubes 9 and 12, Fig. 2, with a compression spring 11 interposed between a flange 14 of the tube 12 and a flange 10 of tube 9. Tube 12 is closed at the lower end and supports the printing pad 17 on a projection 15. A plunger shaft 20 is adjustably situated in the drilling 23 of the tube 12 and has a screw cap 21 at the other end. A compression spring 26 stronger than spring 11 is interposed between the bottom of tube 12 and a flange 19 on the plunger 20. Interposed between the flange 19 and the end guide sleeve 13 of the tube 9 is an elastic annular element 18, for example of rubber, plastics material or nylon. The driving shaft 27 of the machine has a cam 28 for actuating the printing ram. A cam follower 32 operates through a lever 31, 30 on the screw cap 21 to depress the plunger 20 and therefore operate the ram through the compression springs 11 and 26. On the return stroke the elastic annular element 18 acts as a buffer or damper for the recoil of the stronger spring 26. Sheets of paper or the like are fed beneath the guide rails 6 in a direction perpendicular to the movement of the printing plates, by a feed roller 7 and a co-operating nip roller 135. The guide rails are mounted on vertical pivot pins at their ends with one of the rails having a slot to receive the pin adjacent a spring interconnecting the rails which biases them together. Tolerances in the widths of the printing plates are therefore compensated, and the rails are only deformable in the middle unsupported region immediately beneath the ram 1. The inking mechanism comprises an ink drum 38 and ink transfer rollers 68 and 69 which cooperate with an inking roller 70. The spindle 77 of the roller 70 is guided on the lower edges 86 of two guide plates 88 arranged either side of the printing ram 1. The reciprocating movement of the inking roller 70 beneath the pad 17 is provided by a cam 85 on the driving shaft 27 acting through levers 84, 80 and 78.

Abstract: 652,805. Measuring heat-quantities. SOC. ANON. DE COMMENTRY FOURCHAMBAULT & DECAZEVILLE. July 23, 1948, No. 19775. Convention date, Aug. 20, 1947. [Class 97 (iii)] In order to eliminate the density factor in determining the calorific value of a gaseous fuel flowing in a pipe C, a calorimeter M is arranged in front of a diaphragm D which introduces a predetermined pressure drop in the pipe C and in rear of a diaphragm d subjected to a pressure drop proportional to that produced in the main supply pipe C. As shown, the pressure drop over the second diaphragm d is made equal to that over the first diaphragm D by connecting the outlet pipe gh back into the supply pipe C on the downstream side of the diaphragm D in which case the calorific output of the supply gas is proportional to the difference in temperature between the inlet and outlet water of the calorimeter M. In order to ensure complete combustion, air is blown into the pipe El by means of a fan V through a diaphragm d<SP>1</SP> and pressure regulating chamber E which are so arranged that the air is supplied at the same pressure difference as the gas. Surplus air is blown into the gas supply pipe C through the pipe Ek. Alternatively, the diaphragm d and the inlet and outlet pipes may be arranged so as to subject the gas through the calorimeter to a known pressure drop. In this embodiment the upstream side of diaphragm d is connected into the main supply at e as before, but the outlet side of the calorimeter is vented to the atmosphere. The calorific content of the gas is then proportional to #H#T, where H is the differential pressure at the diaphragm D and is measured by a manometer and #T is the temperature difference of the inlet and outlet water of the calorimeter.
