Filed: 1964-11-02
Abstract: 1,065,743. Change-speed control. CHRYSLER CORPORATION. Nov. 2, 1964 [Aug. 25, 1964], No. 44568/64. Heading F2D. In a four forward and one reverse manually controlled countershaft gear, an interlock between a lever 132, pivoted at 136 and actuating a reverse-idler shift-yoke (129), and a lever 96, pivoted at 98 and actuating a first-second speed shift-yoke (90), comprises complementary arcuate segments 184, 186 formed on the respective levers, which obstruct movement of the first-second speed lever 96 from neutral towards an operative setting when the reverse lever 132 is moved towards reverse setting. A further interlock between the 1-2 shift-lever 96 and a 3-4 shift-lever 86 comprises a drift-pin 112 between two balls 126 in a stationary cage between segmental portions of the shift-levers, the balls being also outwardly spring-loaded to engage notches 118 in the segmental portions to locate the shift levers in set positions. A spring-loaded ball-detent 160 similarly locates the reverse shift-lever 180. The three shiftlevers are externally linked to a manual lever 151. The change-speed gear, Fig. 1 (not shown), is of the conventional type in which the 3-4 lever 86 operates a synchromeshed double clutch, and the 1-2 lever 96 a clutch which is similar but carries external gear-teeth for meshing a slidable reverse idler operated by the reverse lever 132.

Abstract: 1,104,867. Rotary-piston internal combustion engines. DAIMLER-BENZ A. G. Oct. 6, 1966 [Oct. 13, 1965], No.44703/66. Heading F1F. A rotary-piston I. C. engine of the kind comprising a three or more-sided piston mounted on an eccentric of a shaft and which on rotation slides by its corners along a multi-arcuate inner surface of the peripheral wall of its housing, as shown a three-sided piston and a bi-arcuate epitrochoidal inner surface, includes in each piston side 13, Fig. 2, a recess 14 of substantially rectangular planform and having a steadily increasing depth over a portion 17 extending from a point adjacent one piston corner 15 to a determined point and a constant depth over a portion 18 extending from the determined point to a point adjacent the next adjacent piston corner 16 with the portion 17 of triangular cross-section and the portion 18 of trapezoidal cross-section having a base which gradually lengthens from zero at the point where the portions 17, 18 meet. The shape of the piston recess is said to produce turbulence in the air for combustion or of the fuel-air mixture to assist in the preparation of the mixture for efficient combustion. Also, at the end of the compression phase, it brings the two portions of the working chamber separated by a zone of the housing inner surface nearer to the engine axis into communication with each other and in the short space of time of maximum pressure achieves the completest possible combustion coupled with low fuel consumption and high power output. The recess may be located in the engine side with either portion 17 or portion 18 being the leading portion in relation to piston rotation.

Title: Improvements relating to single-lens reflex cameras
IPC: G03B19/12
Filed: 1965-10-22
Abstract: 1,097,580. Single lens reflex cameras. I.S. BATJUTA and D.P. SIDOROVA. Oct. 22, 1965, No. 44770/65. Heading G2A. A device co-ordinating the movement of the viewing mirror 6 and the release of the shutter in a single lens reflex camera comprises a first operating lever 12 which, when a shutter release button 14 is pressed, is rotated to uncouple a lever 10 from a link lever 3. The latter rotates under the action of a driving drum 2 thus pivoting the mirror 6 to the dotted line position, the mirror being pivoted at 7 to the lever 3 about an axis parallel to a second axis on which the mirror is hingedly attached to the camera casing by means of an intermediate pivot 8. Rotation of the link lever 3 also rotates, through a detent 24 and an arm 21, a lever 19, an arm 22 of which is urged against a shutter actuating member 25 and an arm 20 of which disengages a stop lever 17 from an axially movable shaft 15 of the first operating lever 12, which shaft and lever are then shifted out of the path of the shutter release button. Closing the shutter causes a member 26 to press the arm 22, thus disengaging the arm 21 from the detent 24 and allowing the mirror 6 to return to its initial position. A plunger (27) Fig. 2 (not shown) is used to return the shaft 15 to its initial position. It is stated that the above described device permits the use of a lens of short focal length, and permits a reduction in the dimensions of the mirror.

Title: Linear hydraulic motor
IPC: F16J1/09
Filed: 1969-09-15
Abstract: 1284774 Pistons PHILIPPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 15 Sept 1969 [18 Sept 1968] 45396/69 Heading F2T In liquid actuated piston 8 having a pistonrod 9, a seal is provided between the piston and a cylinder 1 by means of two grooves 11, 13 and a spool valve, comprising discs 25, 26, 27, which is continuously adjustable to maintain the pressure of the liquid in the groove 11 equal to that acting on the face 10 of the piston. Liquid, e.g. oil, is supplied to a chamber A through a port 4 and to a chamber B through a port 5 and passages 6, 7. The pressures in these chambers, in equilibrium, are in the ratio of the areas of the end faces 10, 12 of the piston 8, and areas of the end faces of the discs 25, 27 have an equal ratio. Hence the spool valve is in equilibrium and a pressure equal to that in the chamber B acts on the disc 27, a pressure equal to that in the chamber A will exist in a chamber 18 surrounding the end face of the disc 25. Thus the pressure in the groove 11 will be equal to that in the chamber A, through the passage 33, providing a seal preventing liquid leaking along the piston from the chamber A. Shallow chambers 33 are provided around the piston 8 and each of these communicates with the chamber B via a passage 34 having a throttle 35. If the pressure in the bearing chambers 33 decreases for any reason, the pressure in the groove 11 will also decrease due to leakage, however the spool valve will then move to the left reducing an opening between a slot 32 in the disc 26 communicating the groove 13 with a passage 24 leading to atmospheric pressure via a chamber 23, a chamber 30, an aperture 20, and a duct 21. Consequently, the pressure in the groove 13 is increased leading to a corresponding increase in the pressures of chambers 13 and the groove 11. This method of sealing means the piston can move with a uniform speed, and hence be used with lathes, milling and grinding machines.

Abstract: 1520368 Character reading system ELETTRONICA SAN GIORGIO ELSAG SPA 3 Nov 1976 [3 Nov 1975] 45796/76 Heading G4R [Also in Division H4] Signals I(x, y) representing the radiant intensity or brightness of a reading area A1 at points P(x, y) are produced e.g. using an optical system and a line of photo diodes. The signals are fed to an analogue processor where the signals are integrated and supplied both to a peak detector and an analogue to digital converter. The signal from the peak detector represents the reference voltage and is proportional to the maximum illumination around the scanned point. The converter produces a digital signal representing the contrast at point P(x, y), S(x, y) = where I(x, y) is the brightness at point P(x, y) and I B  is the brightness of the surrounding region. The contrast is emphasized using a field function which performs an adaptive filtering operation. The function #(#, h) at point P<SP>1</SP>(x+#, y+h) is defined as:- where K1, K3 are constants, K2 depends on background noise, mes A1 is the size of reading area A1 and mes A<SP>1</SP>2 is the size of the area A2 enclosing the points in zones A2 around the reading area A1 and localized at the four vertices of the zone A1 which have A field response R(x, y) at point P(x, y) is calculated over areas A1, A2, A3 R(x, y) = ##S(x, y) #(x+#, y+h)d# dh+K 4  where K 4  is a constant. Since the converter output u(x, y) is proportional to the contrast #(x, y) = K1S(x, y). Since the photocells are sampled so that discrete values are obtained the integrations are formed by summing and the field response becomes, after the defined values of #(#, h) are substituted. Only signals for which v(x, y)#K2 are used and these signals are counted to derive the size of area A<SP>1</SP>2. The values of R(x, y) are examined and binary values of the signals are obtained using the criteria
