Title: Improvements in or relating to photographic roll film cameras
IPC: G01F3/22
Filed: 1936-07-17
Abstract: 463,769. Photographic cameras. ZEISS IKON AKT.-GES. July 17, 1936, No. 19930. Convention date, July 17, 1935. [Class 98 (i)] The shutter-winding means of a camera is coupled with the film advancing means and a restraining deviceprevents a change in the direction of movement of the actuating member for said means until said member has completed its movement of operation. The actuating member 1 is mounted on a ring 2 coaxially with the objective, and carries raised teeth 3 which engages a spring pressed pawl 4. The member 1 drives a rack connected through gear wheels with the film driving roller and a projection 11 on the ring 2 moves the pull lever 12 to wind up the shutter. The pawl 3 can tilt over at the untoothed portion of the ring 2, but cannot tilt when in engagement with the teeth. The movement of the member 1 must therefore be completed before the pawl 4 is free to allow return movement.

Title: Method of calking
IPC: C08L11/00
Filed: 1965-05-12
Abstract: Caulking is carried out by premixing 10 parts of polychloroprene having a molecular weight of from 2000 to 18,000 with 10 to 20 parts of a non-volatile primary plasticizer, then admixing from 1.2 to 2 parts of a poly-functional amine selected from the group consisting of piperazine and amines having the formula NH2-C2H4-(NHC2H4)n -NH2, where n is 0 to 4 with the premix, immediately applying this to an area to be caulked and curing at 40 DEG  to 100 DEG  F. for 10 to 30 minutes, thus gelling the admixture.  The premix may have added to it, with the amine 0.2 to 2 parts lead dioxide and up to 2 parts of zinc oxide while the polychloroprene may contain under 5% of interpolymerized sulphur and from 0.3 to 0.6% of incorporated tetra-alkyl thiuram disulphide and the premix may contain a polyepoxide resin, e.g. the reaction product of a polyhydric phenol and epichlorohydrin.  Specified amines include tetraethylene pentamine while the plasticizer may be n - butyl oleate, dioctyl phthalate or chlorinated biphenyl.

Title: Fluid supply systems

Filed: 1960-06-07
Abstract: 911,190. Hydraulic apparatus. DOWTY ROTOL Ltd. Aug. 22, 1961 [June 7, 1960], No. 19969/60. Class 69 (2). [Also in Group XXXIII] A fluid supply system comprises a fluid supply source 11, a device 22 which is disposed between the source and a mechanism to be actuated and has an outlet 29 connected by a spring-urged valve 30 to an exhaust 33, and a cut-off valve 37, whereby when the pressure developed by the source is below a predetermined level the valves are open to permit substantially all the fluid from the source to pass to the exhaust and when the pressure reaches the predetermined level the valves are operated to close the exhaust and direct substantially all the fluid to the mechanism to be actuated. The system may be incorporated in an aircraft and the source 11 consist of a pump having first and second stages 14, 15 driven by a shaft 13 connected to a ram air turbine 12 which, together with the pump, can be extended into the airstream from a stowed position. The first stage 14 consists of a gear pump which draws fluid from a reservoir 16 and pumps it at low pressure through a passage 17 and offloading valve 18 to the second stage 15 consisting of a radial piston pump which delivers fluid at high pressure through a passage 21, and relief valve 19 to the device 22. When the pump and turbine are initially extended into the air stream and the pressure in the passage 21 from the pump is low, the pressure in a passage 34 is insufficient to move a piston 35 connected to the cut-off valve 37 against a spring 38 and the exhaust passage 33 remains open thus permitting the pressure from the passage 21 to act inside a spool 23 to lift the spring-urged valve 30 from the outlet 29 so that substantially all the fluid from the pump passes through the exhaust 33. When the pressure in the passage 21 from the pump reaches the predetermined value, the pressure differential across an orifice 24 in the spool causes the pressure in passage 34 to move the piston 35 and cut-off valve 37 to close the exhaust 33 which, in turn, causes the valve 30 to close the outlet 29 and substantially all the fluid to pass through orifices 25, 26 to a line 27 connected to an accumulator 28 and the mechanisms to be actuated.

Title: Improvements in or relating to telegraph systems
IPC: H04L25/04
Filed: 1960-06-08
Abstract: 881,205. Code telegraphy. SIEMENS & HALSKE A.G. June 8, 1960 [June 9, 1959], No. 20131/60. Class 40(3). A start-stop telegraph system comprises apparatus for producing correctly shaped pulses corresponding to received pulses and may may be used with a code containing n or n + 1 elements. Each received pulse is scanned at its theoretical centre, and the scanning means is disabled at the end of a predetermined number of pulse intervals after receipt of a start pulse if the last pulse received before that time has stop polarity but is allowed to operate for one further pulse interval if the last pulse received before that time has start polarity. On the arrival of a start pulse at E the bistable stage St1 assumes its Z state, this stage switching to the Z or T state according to the polarity of the received signals. The initial switching to the Z state opens AND gate K2 which allows a pulse of a pulse train T2 to switch a ring counter US to its one state, in which state it allows counters Zl and Z2 to count clock pulses from the pulse trains T1 and T2. Pulses T1 and T2 are 180 degrees out of phase and for a telegraphy speed of 50 bands pulses T1 occur at 10, 30, 50, . . . m.secs. after the beginning of the start signal, i.e. at the theoretical centres of the received pulses. Counter Z1 gives at one ouput pulses at 10, 30, 50, . . . m.sec to AND gate K4 and to scanning gates K6, K7 so that a second bistable unit St2 assumes a Z or T state in accordance with the polarity of the received signal at these instants, the correctly shaped signals appearing at A, At its second output Z1 gives pulses at 20, 40, 60, . . . m.secs which pass through OR gate M1 to be counted by Z2. This counter has a capacity of n + 3, at which count it sends a pulse to switch ring counter US to its zero state which prevents Zl and Z2 from counting. During the (n + 1)th period of 20 m.sec after the end of the start pulse it is arranged that gate K5 delivers a pulse to AND gate K4. If therefore at the centre of this interval unit St1 is in its T state-indicative of a pulse of stop polarity-all three inputs of gate K4 are energised, and it passes a pulse through OR gate M1 to counter Z2. Hence the counters are switched off at the end of the (n + 1)th interval after the end of the start pulse. The last received signal is either the stop pulse of an n element signal or the last element of an n + 1 element signal. If the signal is of an n + 1 element code the unit St2 will not have to be changed to a T state since the last received signal has stop polarity. However, if, at the centre of the (n + 1)th interval, the received signal has start polarity then there is definitely an n + 1 element signal present. In this case K4 does not give a pulse during this period and Z2 does not deliver a pulse to the ring counter until the end of n + 2 intervals after the end of the start pulse.
