Title: Improvements in and relating to hoists
IPC: B66B5/08
Filed: 1953-12-18
Abstract: 758,380. Builders' hoists; position indicators. BRITISH HOIST & CRANE CO., Ltd., and EVANS, P. N. March 18, 1955 [Dec. 18, 1953], No. 35289/53. Classes 78 (2) and 78 (3). A builder's platform hoist is provided with a platform position indicator which is located at a point above the lowest platform level and serves to indicate the level of the platform when it is at another point. The indicator comprises a stationary scale 22 secured adjacent the upper end of the hoist and a weighted movable member 32 provided with a pulley 33. A cable 21, which passes from an achor 34 around pulleys 33, 23, 24, 25 to one end of a control rope 15, is provided with an abutment 28 which co-operates with a sleeve 26 on the platform 11 as it nears its lowest position and so causes the member 32 to move along scale 22. A further abutment 27 on cable 21 co-operates with the sleeve 26 at the upper position of the cable so preventing overwinding by overriding the manual control effected by cable 15 and stopping the winch 10. In a modification, Figs. 3, 4 (not shown) the indicator is not associated with the overwind control and slack in the lower portion of cable 21 is taken up by passing this portion of the cable around a pulley on the lower side of member 32 and anchoring it to the scale. This embodiment also shows a further indicator at the lower end of the hoist. According to another modification (not shown) the indicator may include a warning bell. In a further modification (not shown) the indicator may comprise a spring drum provided with a pointer and having cable 21 passing around and secured to its periphery. Specifications 647,525, 652,920, 657,457 and 676,191 are referred to.

Title: Improvements in or relating to a process camera with automatic electrically controlled accurate focussing
IPC: G03B27/34
Filed: 1958-11-04
Abstract: 902,909. Photographic copying cameras. HOH & HAHNE HOHLUX G.m.b.H. Nov. 4, 1958 [Nov. 4, 1957], No. 35363/58. Class 98 (1). In a process camera wherein the camera back determining the image plane and the copy-holder determining the object plane are movable along the optical axis relatively to the objective, automatic focusing is effected by means of a bridge circuit including two impedances variable in magnitude in accordance with the movements of the camera back and copy-holder, respectively, the output of the unbalanced bridge controlling a drive for one of these two members to restore the balance of the bridge. As shown, a camera with a L-shaped light path has a resistor Ra operated by movement of the copyholder 8 in parallel with a resistor Rb operated by movement of the camera back 9 in one arm of a bridge of which the ratio arms are arranged to be equal, being provided by resistors B 1 , B 2  with a variable balancing resistor B, the fourth arm being formed by a resistor of magnitude appropriate to the focal length of the objective. The amplified out-of-balance output of the bridge detector arm drives a reversible motor 6 for moving the copy-holder 8 after the camera back has been set to a position corresponding to a chosen enlargement ratio, thus satisfying the lens equation 1/a+1/b=1/f. To accommodate the use of objectives of different focal lengths, the appropriate resistor such as R f1  or R f2  is placed in circuit in the fourth bridge arm under control of a switch 13 which may be mechanically or electrically coupled to the objective changing mechanism. Fixed resistors Va, Vb together with resistors Ea, Eb for adjusting the total resistance of the a and b parallel branches to suit the mechanical requirements are provided together with a variable resistor S in the copy-holder branch a to take account of the actual object plane occupied by the original on the copy-holder and a fixed resistor G in the branch a which may be shorted out by a switch 11 closed by movement of the copy-holder to a position closer to the objective than is normal for producing extreme enlargements. Trimmer resistors Ta, Tb, Tf, TG may be provided, resistors Ta, Tb being alternately brought into operation by switches 12 simultaneously with change of objective, switches 12 and 13 being operated together. In a modification, which is not described in detail, two non-adjacent arms of the bridge are made proportional to a - f and b - f while the other two arms are each made proportional to f, so satisfying the alternative lens equation (a-f) x (b-f) = f<SP>2</SP>.
