Abstract: 1,187,465. Automatic exchange systems. SOC. ITALIANA TELECOMUNICAZIONI SIEMENS S.p.A. 20 Oct., 1967 [20 Oct., 1966], No. 47797/67. Heading H4K. Circulating delay line stores L 1  to L 4  are time shared to provide registers for the detection and storage of dialled digits, the time slots being grouped and each such group constituting a register, the first time slot of which in parallel across the delay lines is used to obtain a certain count of consecutive loop conditions sampled for the line being served so as to signal loop made or broken without responding to transients, the second time slot being used as a counter to time the duration of a detected loop transition to distinguish inter-digital pauses, the third time slot being used to record call sequence state, and the remaining time slots of each register group being employed to store dialled digits. The lines being served are supervised over two leads multiplexed on to buses A and C, the C bus being used to detect idle and busy states while the dialled digits are taken off the A bus. The delay lines L 1  to L 4  circulate their data through adder/subtractor RC and can be read out to buffer register RU. A logic circuit RK receives the instantaneous condition of channels A and C together with the parallel outputs of the delay lines. The logic circuit RK controls the incrementing or decrementing of the storage compartments, each comprised by a time slot circulating in parallel round the delay lines, by a command signal C p  and a sign signal S. As and when necessary a storage compartment is cleared by a signal R in the appropriate time slot. If a loop break is adjudicated present a pulse is injected into delay line L 5  in the first time slot of the associated register time slot group and, by use of a single time slot delay R fs , a pulse is also injected into the second time slot of the group in L 5 . The presence of the pulse in the second time slot of L 5  activates the timer comprised by the corresponding storage compartment of delay lines L 1  to L 4 . When the loop is adjudicated closed the pulses in the first and second register group time slots of L 5  are cancelled and, depending on the count achieved by the timer, a digit store is incremented by one or a new digit store is taken into use for the next digit. The particular storage compartment of a register time slot group currently active in accumulating the impulses of a digit is marked by a pulse circulating in L 5  in the corresponding time slot. One group of time slots circulating in L 1  to L 4  is employed as a ten-stage counter to comprise a 24-hour clock for call timing. The logical functions necessary to order the data in the circulating stores are set out in Figs. 6 to 9, not shown.

Abstract: 1,093,439. Sawing. WILLIAM CROSLAND Ltd. Oct. 10, 1966 [Nov. 11, 1965], No. 47919/65. Heading B5L. A jig saw comprises a frame 21, Fig. 1, and a headstock 23 providing mountings for upper and lower clamps 70, 36 for a vertical saw blade 29, the clamps being disposed respectively above and below a cutting table 27, drive means for reciprocating the clamps whilst maintaining the saw blade under tension, and one of the clamps being automatic so as to grip its saw end upon engagement of the end with the clamp, the other clamp being biased towards a withdrawn or workpieceloading position wherein it holds the blade clear of the upper surface of the table when the saw is released from the automatic clamp. The automatic clamp may be the lower clamp 36 which is mounted on rods 34, 35 slidable in bearings in the frame and connected by a rod 38, Fig. 6, to an eccentric 39 beltdriven from a motor 22. Springs 43 extend between the frame 21 and a crosspiece 42 to urge the clamp to an upper position when the motor is not driven. The clamp consists of a block 49, Fig. 7, against which the blade 29 is pressed by a knurled roller 51 on a spring-urged lever 50. To disengage the clamp, a cam 57 can be rocked by a handle to engage a lever 55 on the pivot shaft 52 of the spring-urged lever 50, the roller 51 thus being moved away from the block 49. The movement of the cam is also effective to actuate a switch controlling the motor which is thereby switched off before release of the clamp. The blade extends through a square hole in the table, the hole supporting the back of the blade, and is secured to the upper clamp 20, Fig. 10A, at the end of a rod 72 slidable in a bearing 73 in the headstock 67 which is carried by a C- haped member 23 secured to the frame. The rod 72 is acted upon by a spring 76 which tensions the blade and acts to return the blade during reciprocation thereof. A further spring 83 acts to raise the support for the upper end of the spring when the blade is released from the lower clamp so that the lower end of the spring is clear of the table during positioning of a workpiece 107. The upper clamp 70 can be lowered by pivoting of levers 88 which have rollers for engaging the clamp which is lowered until the lower end of the blade engages the automatic clamp 36. A work steady 97 is urged by springs 99d downwardly against the workpiece and can be raised by rotation of a cam 99a abutting levers 94 connected to the steady. The steady has a pair of limbs 98 and a sighting arrangement comprising an apertured plate 100 can be lowered between the limbs. In another embodiment, the upper clamp is the automatic clamp and the lower clamp is biased to withdraw the blade clear of the table. The machine may have different sizes of headstock 23 for selective attachment to the frame.

Abstract: 1277750 Motor vehicles G JACHOT and F PERALES 2 Oct 1969 [2 Oct 1968] 48587/69 Heading B7H [Also in Division F2] A compressed air braking device for tilting cab motor vehicles has at least two reservoirs 1, 2 supplying compressed air to a dual braking circuit in which are interposed a pedal operated control valve 33 rigidly secured to, and disposed adjacent the tilting axis of the cab and controlling air supplied to a distributor 18 attached to the vehicle frame to effect normal and emergency braking of front and rear brake cylinders 14, 21 and give a progressive braking action. In normal braking operation when the driver depresses brake pedal 4 a plunger 102 in valve 33 is operated to act on a piston 99 through a compression spring 103 causing a first valve member 94 to disengage a seat 95 allowing air to pass from reservoir 1 into a chamber 97 through an inlet 38 and outlet 43 and to distributor inlet 45. The air pressure acts on a distributor piston 78, which through a spring 79, actuates a second piston 60 thereby unseating valve member 51 air then passing from reservoir 1, and by way of inlet 31 and outlet 24 to normal inlet 19 of rear brake cylinders 21. Air also passes through a channel 69 to depress pistons 63, 64 thereby unseating a valve member 52, air from reservoir 2 passing to the front brake cylinders via inlet 32 and outlet 17. If air pressure in reservoir 1 drops below a predetermined value the pressure in valve chamber 97 cannot balance the spring 103 the latter causing member 94 to unseat and bear on a spigot 122 of an intermediate piston 115 which unseats a second valve member 109 to allow air from reservoir 2 to enter a chamber 112 through an inlet 39 and pass via outlet 44 to an emergency inlet 46 of distributor 18. Air passes from the inlet 46 into a chamber 67 and acts upon two diaphragms 65 to separate pistons 63, 64 the latter moving downwardly to unseat valve member 52, air passing to the front brakes via inlet 32 and outlet 17, and also via a passage 73 past a flexible diaphragm valve member 53, a chamber 72 and an emergency outlet 28 to the emergency inlet 22 of rear brake cylinders 21. When the pedal 4 is released first valve member 94 closes and air in a chamber 81 of distributor 18 escapes to atmosphere through valve outlet 43, chamber 97, and duct 107 and orifice 105, and in chamber 67 through ports 46, 44, a chamber 112, an axial duct 117 orifices 118, chamber 119 and orifice 121. If both reservoir pressures fall below a predetermined value, the driver actuates a manually operated valve 5 to allow air to pass from a further reservoir 3, via conduits 29, 27 and valve 26 to inlet 22 to actuate the rear brakes only.
