Title: Improvements in and relating to viewfinders
IPC: G02B23/14
Filed: 1958-01-31
Abstract: 881,752. View-finders. VOIGTLANDER A.G. Jan. 31, 1958 [Jan. 31, 1957], No. 3310/58. Classes 97(1) and 98(1). In an Albada type view finder the field bounding frame is provided on a curved surface so that it lies within the field angle of the finder beam and is illuminated by light coming mainly from the same part of the subject field as that into which the frame image is to be reflected. As shown in Fig. 1a, the finder comprises a plano-concave lens 1 and a plano-concave lens 8 with a transparent block 5 therebetween. The adjacent surfaces 4 and 6 of lens 1 and block 5 are separated by a small gap of low refractive index, for example air, so that these two surfaces act as a partly transparent concave mirror which images at infinity a reflecting field-bounding frame 11, the latter being cemented to the convex surface of lens 8. One or both of surfaces 4 and 6 may have deposited thereon reflecting coatings as of the interference type. The lens 8 may be replaced by a plane parallel plate 81 made up of two cemented lenses having the field-defining frame 11 at the curved cemented surface thereof. This plate, as shown in Fig. 3, may be separated from block 5, and so be movable perpendicularly to the view finder axis to compensate for parallax, preferably with the aid of a scale 16 in a recess 17 and a fixed pointer 18. This movable plate may be coupled as by a lever to the lens focusing mechanism of the camera or to the adjustable mirror of a range finder, the block 5, in the latter case, being split diagonally and provided with a partly transparent surface acting as the fixed mirror of the range finder (Fig. 5 not shown). Plane parallel plates carrying field defining frames of different sizes may be combined together into one body, so that any desired frame can be moved into the light path (Fig. 6 not shown). In a further form the field defining frame 11 is cemented between curved glass shells. Specification 881,751 is referred to.

Title: Automatic stepless variable speed hydraulic drive
Inventor: HANS KURT
IPC: F16H61/46
Filed: 1958-01-31
Abstract: 877,343. Hydraulic transmission systems. INSTITUT FUR FORDERTECHNIK DES MINISTERIUMS FUR SCHWERMESCHINENBAU. Jan. 31, 1958, No. 3334/58. Class 69 (2). The infinitely variable transmission ratio of an hydraulic transmission system 2, 3 is controlled by a piston 12 acted on by differential forces depending on the speed of the prime mover 1 and the resistance to motion. For starting, a lever 11 is set to position 11a (forward) or to 11b (for reverse drive). Acceleration of engine 1 then causes a governor 14 driven thereby to force piston 12 to the right whereon an engine driven pump 4 supplies liquid via lines 24, 25 and the piston valves 12, 10, to a servomotor 8 which shifts to the right or left to " start " engine driven pump 2 in the correct sense. Servomotor 8 is prevented from moving further by springs 9. The pump 2 and motor 3 are connected in a closed circuit so that back pressure in accordance with the resistance to motion encountered by the motor 3 builds up in one of lines 26, 27, and hence the pressure in one of lines 28, 29 forces pistons 13, 12 back to the position shown, so that servomotor 8 is held in its new position. If excessive resistance is encountered, the high pressure in line 28 or 29 forces piston 12 to the left, when the cylinder of servomotor 8 is exhausted and servomotor 8 returns to its initial central position. If extra speed is required, further acceleration of engine 1 forces piston 12 further to the right and more liquid is admitted to servomotor 8, forcing it further to the right, so that the eccentricity of pump 2 is further increased. In a modification, governor 14 is replaced by a piston supplied with pressure liquid by a pump driven by engine 1.

Projectors and projectiles. -In a toy gun adapted to shoot elastic bands 13, one end of each band engages a notch in the forward end of the barrel while the other end of each band passes over one of a series of lugs 7 projecting radially from a rotary member 6. A trigger 8 pivoted below the rotary member is provided with two stops A, B. One of the lugs 7 is normally pressed into engagement with the upper stop A by the action of the stretched bands. Pulling of the trigger permits the lug to rotate into contact with the stop B and releases the band engaging the topmost lug 7. The pressure of the lug against the stop B, due to the action of the remaining band or bands, returns the trigger to its original position and allows the next lug to engage the stop A. The gun is loaded by means of a loop-member 14 pivoted by slotted plates 15 on the axle 5 of the rotary member and normally held in the position shown in Figs. 2 and 6 by the engagement of its rearward end with a pin 17. The loading operation consists in looping a band over the topmost lug 7 and then rotating the rotary member by means of the loop-member 14, the operation being repeated for each band. During loading, the gun must be held with the barrel inclined downwardly to enable the trigger to operate.
