Abstract: 1409874 Erecting structures L P HAMBLIN and A S LANBURN 20 Dec 1972 [25 Sept 1971] 44801/71 Heading B8B [Also in Division F2] An extensible and retractable crane structure comprises two spaced sets of jointed main frame or strut members 10 interconnected by cross bracing tie members 11 and is arranged so that the tie members 11 automatically engage with the main frame members 10 on extension to form a rigid extended structure and automatically disengage on retraction so that the frame and tie members 10, 11 may be conveniently stored when not in use. As shown, the main frame members 10 of each set are jointed together via pivot pins 14 and freely pivotally carry, via pins 16, the cross tie members 11, the two spaced sets being coiled, when not in use, on storage drums 21 arranged each side of a pair of synchronously driven leadscrews 23. Rollers 15 on the main frame pivot pins 14 are guided via tracks 25 to the leadscrews 23 whereby the two sets of main frame members 10 are drawn off the drums 21 and vertically raised via the leadscrews, trunnions 17 on the free ends of the cross tie members 11 being guided by tracks 26 to automatically interlock in jaws 18 which are formed in the pivoted ends of the members 10 and which close over to lock on the trunnions 17 when the members 10 are vertically extended, such that continued operation will keep drawing the frames 10 and their ties 11 off the drums 21 and discharging the rigid locked structure from the top of the leadscrews 23. A member 19 (Fig. 7) is pivotally connected at the top end of the uppermost main frames 10 to prevent collapse of the upper end of the structure on extension. The frames 10 and ties 11 may be of steel tube (as shown) or formed from pressings (Figs. 5 and 6, not shown). In an alternative embodiment (Figs. 11 to 15, not shown) the tie members (31) are pivotally jointed at (36) in opposed pairs on each of the main frame members (30) of one set and are arranged to fold in a triangular form and engage via ball ends (37) at the triangular apex in similar ball-shaped jaws (38) formed in the other set of linked struts 28, the structure being extended and retracted by leadscrews as before. The main members (30) together with their pivoted tie members (31) may be coiled on the storage drum in an opened out, i.e. planar form as in Fig. 11 (not shown) or in a closed form, i.e. with the tie members (31) inwardly folded one over the other on the main members (30) as in Fig. 12 (not shown). In a further embodiment (Figs. 16 to 19, not shown) the two sets of main frame members (40) are separately stacked in two storage magazines (Fig. 16, not shown) and instead of each set being pivotally hinged together the main frame members (40) have hooked ends whereby as they are lifted out, one at a time, from each magazine during extension, the hooked ends are interengaged and locked by the tie members (41) as they are swung into position via guides (49), the main frames in the magazine being fed to the leadscrews via endless driving chains (50) having pegs (51) projecting between the frames.

Title: Pcm time division mutliplex exchange systems
IPC: H04Q11/04
Filed: 1973-09-26
Abstract: 1447522 Automatic exchange systems SIEMENS AG 26 Sept 1973 [28 Sept 1972] 44983/73 Heading H4K In a p.c.m., t.d.m. exchange system four wire incoming/outgoing highway pairs are formed into groups, each group Gn including a switch through units and having its own decentral control unit ESn as described in Specification 1,351,408. The groups are interconnected by Go and Return (relative to an originating group) intermediate highways and during the setting up or disestablishment of a connection the Return intermediate highway is used to signal the address of the called group and the address relative to the called group of the Return intermediate highway from the called group to the decentral control unit of the calling group. For a call originating in group G1 to a destination reached by group 15, a central control first determines a free path in known manner and then signals to the decentral control unit ES1 of group G1 via an operating field control over wire LZ1 all the information needed to set up the connection with the exception of the above mentioned addresses. The information includes the address of the Go intermediate highway to be used relative to group G1, the time slots to be used on this highway, the addresses of the pairs of highways of groups G1 and G15 to be interconnected together with the time slots thereon which are to be interconnected. The control unit ES1 can then establish a connection to the relevant time slot on the intermediate highway Za, interconnecting groups G1 and G15. An intermediate highway address register in group 15 is thereby activated to transmit the two missing addresses to the central unit ES1 over highway Zb during a special signalling time slot. Control unit ES1, now having the address of group G15, transmits all the information necessary to complete and hold the connection to control unit ES15 over a special order wire LV. A similar signalling operation takes place on disestablishment. The intermediate highways use a super multiplex cycle comprising 64 time slots, the 64th slot being used for signalling.

Title: Method and apparatus for measuring the thickness of objects
IPC: G01B15/02
Filed: 1974-10-17
Abstract: 1490076 Measuring thickness EXATEST MESSTECHNIK GmbH 17 Oct 1974 [19 Oct 1973]  45017/74 Heading G1A [Also in Division G4] The invention concerns means for interpreting pulses from a measuring device, whose number has an exponential relationship with the value to be measured: a counter 40 is pre-set to a value representing the limit of the measurement and is then altered by a number of unit increments depending upon how far the number of pulses departs from the number corresponding to the limit value. Pulses nx are applied to a gate 10 which is enabled for a period of 1 second; the pulses may be derived from a scintillator and photo-multiplier responding to gamma radiation passed through a sample whose thickness is to be determined from a radio-active source; or x-rays &c. may be used. The pulses released by gate 10 are counted at 14 and when a number of pulses, set at 24, and depending upon the maximum measurement, have been counted a comparator 20 releases a pulse which via an OR-gate 28 pre-sets a down counter 40 so that maximum measurement e.g. 100mm ... The pulses from gate 10 are divided at 18 by a value D dependent upon the unit of measurement and the result added to an accumulator 36. The pulse from comparator 20 also zeroizes a counter 16 and applies the current count in accumulator 36 to a comparator 38. Counter 16 then continues to count the pulses from gate 10 until it reaches that value applied to the comparator 38 when a further pulse leaves OR gate 28 to reset the counter 16 and transfer a new value from accumulator 36. Each pulse from OR gate 28 reduces the count in 40 by one unit e.g. 0.1mm. The number of pulses from gate 10 which have to be counted to produce the next pulse to counter 40 is thus reduced by 1/D at each step providing the exponential function. A modified arrangement Fig. 2 (not shown) has means for correcting for errors due to overlapping pulses from the photomultiplier; for compensating for the temperature and composition of the material being measured; and for interpolating a further decimal place in the measurement using the remainder pulses. In an alternative arrangement Fig. 3 (not shown) the counter 40 is pre-set to the minimum measurement and increased at each step.

Abstract: 1419440 Open end spinning ELITEX ZAVODY TEXTILNIHO STROJIRENSTVI GENERALNI REDITELSTVI 28 Sept 1973 [5 Oct 1972] 45416/73 Headings D1D and D1F Simultaneous piecing in all spinning units of an open end spinning machine is performed by a device comprising a contactless detector of the motion of withdrawing and winding rollers of the spinning units, the detector being connected to a counter which is provided with at least two adjustable count detectors. In Fig. 1, the withdrawal and winding rollers 6, 7 are geared together and are reversely driven following a signal generated by the attendant. The motion of the winding roller is detected by a notched wheel 13. After a predetermined length of yarn has been returned to the spinning chamber 12, counter 15 causes a signal to appear at the output of count detectors 18, 19 to disengage reversing clutch 5 and engage forward clutch and the engagement of fibre feed clutch 3. The count detector can be used to control a 2 stage braking of the winding rollers during stoppage of the machine to avoid yarn breakage. In Fig. 3 a separate counter (30) is used to time the interval between the commencement between starting the reverse motion of the withdrawal rollers and the starting of the fibre feed. During stoppage of the machine fibres continue to be fed into the spinning unit and the amount of yarn thus spun and withdrawn during a 2 stage breaking can be measured. In Fig. 4, the count detectors can be connected to different open end spinning machines. A tachodynamo can be mounted on rollers 6 and 7 to control braking separately from the 2 stage braking.
