Title: Improvements relating to the determination of unbalance of vehicle wheels
Inventor: BEISSBARTH HERMANN HERBERT
IPC: G01M1/22
Filed: 1959-06-12
Abstract: 927,356. Testing dynamic balance. O.BEISSBARTH, [trading as OSMEND BEISSBARTH MASCHINENBAU]. June 12, 1959, No. 20145/59. Class 106 (2). Apparatus for determining the extent and direction of unbalance of a vehicle wheel 1, in which the wheel is secured coaxially to a spindle 2 and the spindle is supported for oscillatory movement about an axis 3 transverse to its own axis and is spring-biased towards a mean position, comprises a rotatable indicator 5 driven in synchronism with the spindle 2, a light source 8 adapted to illuminate the indicator 5 intermittently, the timing of the illumination being controlled by means 7 responsive to oscillation of the spindle 2, and a feeler 9 displaced in use to an extent proportionate to the maximum amplitude of the system and co-operating with a scale 10. In use, the wheel 1 is driven by a roller engaging its periphery so that its period of revolution is less than the natural period of resonance of the system. A U-shaped follower 6 spans the spindle 2 and has a contact 7 which makes and breaks contact with the spindle 2 on oscillation of the spindle. A discharge lamp 8 is connected in the circuit of contact 7 and flashes momentarily when the contacts 7 are broken, thus illuminating one section only of the disc 5, and this section gives an indication of the angular position of the imbalance of the wheel. The wheel is then allowed to slow down, the follower 6 being removed from its position spanning the spindle, and as the wheel passes into resonance with the oscillatory system, the maximum amplitude of oscillation is noted from the position of a pointer 9 co-operating with a scale 10. This gives a measure of the amount of unbalance of the wheel. In an alternative embodiment, Fig. 2 (not shown), the contact 7 is on an arm spring-urged into contact with the spindle 2, the lamp 8 is carried by an arm oscillating in unison with the movement of the spindle and the disc 5 is opaque with transparent markings, which are viewed from the side opposite to the lamp.

Gears 40, 41 integral with the countershaft 20 mesh with a gear 38 rigidly secured to the intermediate shaft 16 and a gear 42 which is rotatably mounted on the output shaft 13 and is lockable thereto by a dog clutch 43 or a synchromesh device 44. The clutch 43 alternatively connects the intermediate shaft 16 to the output shaft 13, Fig. 1. Selector forks 49-51 are actuated manually from a shaft 54 and arm 55 to control clutches 32, 33, 36, and clutch 43 is controlled by a selector fork 53 on a selector rod 47 actuated by a compressed air ram 56. A power take-off shaft 58 is connectable to the layshaft 18 by means of a manually controlled clutch 61. Operation.-To obtain any of the eight forward speeds, one of clutches 32, 33 is operated to cause the intermediate shaft 16 to rotate at one of four different speeds, and clutch 43 is operated to cause the output shaft 13 to be rotated at the same speed as or at a different speed from the shaft 16. To obtain either of the reverse speeds, the clutch 36 is operated to cause the countershaft 20 to rotate in the same direction as the input shaft 11 and the intermediate shaft 16 to rotate in the opposite direction. Clutch 43 is operated to cause the output shaft to rotate at a speed which is the same as or different from that of the shaft 16. The dualrange gears may be chosen so as to provide an overdrive.

Title: Photoelectric detector device
IPC: G01B11/00
Filed: 1974-05-10
Abstract: 1465791 Detecting position photo-electrically NIPPON KOGAKU KK 10 May 1974 [10 May 1973] 20821/74 Heading G1A Apparatus for detecting whether a mark lies within or outside a predetermined range comprises: two light modulating means; means for forming an image of the mark in the vicinity of each modulating means; means for producing relative oscillation between the modulating means and the image or images over a range at least equal in length to the predetermined range; and means responsive to the light outputs from the modulating means for producing a signal representing the position of the mark. The light modulating means preferably comprise slits in an opaque plate, or one slit and one opaque mark in a translucent plate, disposed at positions corresponding to the images of the mark when at respective ends of the predetermined range. The output signal is preferably of one polarity when the mark lies within the predetermined range and of opposite polarity when outside. In one embodiment, Fig. 3, an image of a mark 12 is split by a half-reflecting mirror 17 and focused on two slit plates 14, 18. An oscillator 21 drives a scanning means 16 which causes the images to oscillate over a distance at least equal to the predetermined range and to illuminate both slits cyclically when the mark is at the mid-point of the range. Photo-cells 15, 19 behind the slit plates 14, 18 produce alternating signals which when combined in a differential amplifier 20 and synchronously rectified at 22, produce in a display 23 an output current which is positive when the mark lies within the predetermined range and negative when outside. Fig. 4(a) illustrates the components 24, 25 of rectified current attributable to the respective individual detector signals, and Fig. 4(b) the combined output 26 resulting from subtracting 25 from 24. Alternatively Figs. 6, 7 (not shown) a single translucent plate (37) having a slit (34) and an opaque mark (35), is used with a common detector (15) to produce the desired signal. A scanning device, Fig. 5, comprises a glass block 29 in the path of the light, set in a rotatable moving- coil element 30 driven by the oscillator 21. Other light-modulating means include: a single plate with a pair of slits; a single translucent plate with a pair of opaque marks; and pairs of plates having similar marks or slits and being driven to oscillate in opposed senses. Where the modulated light signals are themselves of opposite polarity a single common photo-cell may be used. Signal subtraction, where required, may be effected at the photo-cell outputs in a differential amplifier; or by demodulating them separately by reference signals of opposed phases; or by demodulating them independently and comparing the rectified signals in a differential amplifier.
