In a laser pulse-echo distance measuring system the laser transmits two pulses and the distance measurement is made utilizing the counted time interval between the second transmitted laser pulse and the echo pulse later than the received first echo by an interval equal to that between the two pulses transmitted. In an embodiment a counter 5 is started and stopped by bi-stable circuit 13 triggered by the first and second laser pulses, the decoded counter output energizing an AND gate 9 connected to the stop input of measurement counter 10. The output of bi-stable circuit 13 connected to the stop input of counter 5, starts counter 10. The effect of interference is thereby reduced. Two receiver photo-multiplier tubes 41, 42 may be used to reduce receiver noise. In another embodiment, where the interval between the laser pulses is relatively long, counter 5 comprises several decades, Fig. 2 (not shown).

Title: Lenses
IPC: G03B9/02
Filed: 1976-12-16
Abstract: 1525319 Interchangeable lens systems FRANKE & HEIDECKE GmbH 16 Dec 1976 [17 Dec 1975] 52515/76 Heading G2A An interchangeable lens system has a lens tube 1 within which a lens mount 6 is axially displaceable, the lens tube itself also being axially displaceable from the Fig. 1 position, which is the picture-taking position, into the Fig. 2 position, in which the system is uncoupled from the camera and may be detached therefrom. The Fig. 1 position is shown in more detail in Fig. 3. The lens mount 6 carries the lenses 7, and focusing is effected by a sleeve 9 which has a threading engagement with both mount 6 and tube 1. Thus rotating sleeve 9 by means of its knurled ring 10 imparts an axial focusing movement to mount 6. Lens tube 1 can slide axailly in a bayonet ring 3 which can engage with a bayonet joint 4 on the camera. The blades of the iris diaphragm 8 are driven by a drive ring 13, 13' from a positioning ring 14, driven in turn from a diaphragm-setting ring 20, 19. Rings 20 and 14 are coupled by a lever 21 which is pivoted on ring 20, and is spring-urged upwards into the coupling position shown in Fig. 3 only when the lens tube 1 is in the Fig. 3 (picture-taking) position. When lens tube 1 is pushed into the camera (Fig. 2 position), lever 21, which passes through a slot 23, is pushed down into the broken line position. Thus rings 20 and 14 are no longer coupled together. Lever 21 now locks ring 20 and bayonet ring 3 together, so that rotating ring 20 by means of its grip portion 19 disengages the bayonet ring 3, and hence the whole lens system, from the camera. When the lens system, or another one, is re-mounted on the camera by engaging the two bayonet fittings, tube 1 is pulled out so that the position of Figs. 1 and 3 is reached again.

The container comprises a wire mesh base 11, sides 17 and sides 16 which extend above the level of the tops of sides 17. The sides 17 are hinged to the base by the hinges shown in Fig. 3 which are formed of sheet metal and stiffen the corners of the base. Members 25 extending from sides 17 are bent at 26 to provide hinge pins which extend between the plates 22, 23 to hold the side erect until the side is manually raised, when the gap 28 in plate 22 and the bend 29 permit the side to be pivoted inwardly or outwardly about its hinge pins. A similar hinge arrangement 21, 31, 32 for side 16 has no bend 29 and the side pivots inwardly only. Springs 33 connect the sides to the wire and exert an over-centre action when the sides are pivoted. Extensions 41 of the taller sides 16 engage with parts 42 on the base of a similar container when erected containers are stacked. When containers are in stacked configuration the shorter sides 17 can be hinged outwardly to permit access to the contents. The base is provided with parts 43 which engage with parts 42 of an upper container when collapsed containers, with the sides folded inwards, are stacked. Instead of the wire mesh shown the sides may be filled in with sheet plastics material and the bottom surface of base 11 may be reinforced by diagonal metal strips. The base may be constructed of sheet metal or covered with plastics material.

IPC: C06F1/20
Abstract: 536,072. Packeting match books. RAHE, S. E. Dec. 13, 1939, No. 32113. [Class 94 (i)] Relates to machines for making match books and consists in providing a machine with means for delivering a number of match books in a closely-associated series, means for gripping each book of the series individually, means for spreading the grippers laterally to space the books apart, and means for discharging the books into as many stacks as there are books in the series. The discharging-device reverses the position of successive books as they are fed to a stack and arranges all the books in a stack to face one direction. The books 20, Figs. 1 and 5, are delivered from the making-machine to a conveyer 21 on which they are held by clips 22, the conveyer moving step-by-step to bring a series of books into position for transfer. The projecting ends of the books are gripped by a set of jaws 42, and the jaws are then moved horizontally by a reciprocating carriage 55, and are also swung through a right angle by a shaft 41 which is journalled at its ends in the carriage 55. This movement brings the series of match books above the stacking mechanism, as shown in Fig. 6, and during this movement the grippers are separated in an horizontal direction. For this purpose, each gripper support, which is splined on the shaft 41, is connected to a lazy tongs 67, and the horizontal movement of the carriage 55 causes the lazy tongs to be expanded by cams 72 oscillating about vertical pivots 73. When the jaws arrive in the position shown in Fig. 6, they open and drop the books into receptacles 92, a hinged plate 113 guiding the books into the receptacle. Each receptacle 92, Fig. 8, has two contiguous fixed sides 94 and a pivoted side 106, and is pivoted at its centre on a pin 109. All the receptacles of the series are connected by links to a bar 98 which is reciprocated periodically to turn the receptacles through a right angle about the pin 109 between the delivery of successive match books. After each receptacle has received a book and has been rotated, plungers 134, Fig. 6, pass through openings 136 in the back of the receptacle and move the book broadside into a runway 137, Fig. 1, against a movable stop 138 to form a stack ready to be boxed. The turning of the receptacle through a right angle reverses successive books in a stack end for end.
