Title: Improvements in or relating to Digit Storage and Transmission Means.
Inventor: RHODES JOHN GEORGE LAYCOCK
IPC: H04Q3/42
Filed: 1968-01-02
Abstract: 1,195,141. Impulse transmitters. TELEPHONE MFG. CO. Ltd. 20 Dec., 1968 [2 Jan., 1968], No. 282/68. Heading H4K. [Also in Division G4] The invention relates to a means controlling writing in and reading from a digital data memory and is particularly for use in telephone systems to provide dialling pulses having a predetermined gap between signals indicative of a particular digit and a larger predetermined gap between consecutive digits. Removal of a telephone handset causes resetting of all circuits via delay DC and reset circuit RS and a key pressed on the handset causes a decimal to binary coded decimal converter to produce a signal applied to AND gate SAG (Fig. 1, not shown) enabled whenever a key is pressed to set flip-flop MC1 to overcome discrepancies that may otherwise be produced by contact bounce. The flip-flop supplies a signal to AND gate ISC enabled by a single pulse recirculating in a 16- stage shift register ISG. A pulse from DSC enables AND gate AG2 and inhibits AND gate AG1 via inverter I1 to cause the circulating pulse to be delayed by one stage. The pulse from ISC also enables AND gates IAG1-IAG4 to supply the B.C.D. number to recirculating memories BSL-4. A 16-stage shift register OSG contains a pulse initially recirculating in synchronism with the pulse in ISG but due to the extra delay provided by BD1 is now one stage ahead of the pulse in ISG. Coincidence of the pulse in OSG, absence of the pulse in ISG and a signal indicating that a counter CTR-O enables AND gate OSC to supply a signal I3 causing the pulse in OSG to be delayed one stage by BD2 and causing readout of the signal from memories BS1-BS4 via AND gates OAG1- OAG4 and preventing regeneration via AND gates CAG1-CAG4 and storage of the number in the counter CTR. A clock pulse generator CG produces pulses of frequency 30 KHz which are divided by scale of ten counters DC1-DC3 to produce pulses of 30 per second. These are passed by AND gate AG7, divided by 3 and then used to count down the counter CTR to produce a series of pulses at the rate of 10 per second equal in number to the number stored in the counter. The OSC signal causing readout of the data from memories BS1-BS4 also sets flip-flop BC2 to enable AND gate AG6 to apply a 30 Hz signal to unit PD causing division by 24. The OSC signal also sets flip-flop BC3 which is reset by the divided signal causing a gap of 0À8 seconds between consecutive digits read out before AND gate AG7 can be enabled. The units are preferably Field Effect Transistor integrated chip circuits to enable the units and push buttons to replace a conventional rotary dial telephone. A flip-flop BC1 controls an electromagnetic relay ONR to simulate the off normal function of a rotary dial, the flip-flop being reset by AND gate AG5 only when all the digits applied by the push buttons have been transmitted.

Title: Purification of gas mixtures
Inventor: SCHUFTAN PAUL MAURICE
IPC: C01C3/00
Filed: 1963-01-04
Abstract: Two types of contaminants are removed from a gas prior to cooling by passing the gas at constant pressure through one of a first pair of adsorbers to remove one type of contaminant and then through one of a second pair of adsorbers containing zeolitic molecular sieves to remove the other type of contaminant, both pairs of beds being arranged to operate in alternate cycles of purification and reactivation, whilst the contaminants are of the type which would settle out in the solid phase in the subsequent cooling step.  The first type of contaminant is defined as having a high melting point and low vapour pressure and liable to condense in the solid state at -70  DEG C. or above, e.g. H2O and C6H6, whilst the second type of contaminant has a lower melting point and higher vapour pressure and is liable to condense at below -70  DEG C., e.g. CO2 and C2H2. The treatment of air containing H2O and CO2 and coke oven gas containing C6H6 and C2H2, is mentioned.  The adsorbers may operate at below ambient temperature but above -30  DEG C., both adsorbers preferably at the same temperature.  The adsorbent for the first pair of beds may be silica gel, activated alumina or "Sorbeads" (Registered Trade Mark).  The two pairs of beds are preferably operated so that their purification and reactivation periods are the same.  Each pair of beds may be reactivated using separate contaminant-free gas streams of the first pair of beds may be reactivated using the hot gas stream which has initially reactivated through the second pair of beds.

Title: Improvements in or relating to brakes for tractor trailer combinations
IPC: B60T7/20
Filed: 1924-01-08
Abstract: 209,438. Winn, S. B. Jan. 8, 1923, [Convention date]. Brakes, arrangement of; interlocking and guarding against wrong movements. - Relates to a compound vehicle in which the front end of a two-wheeled trailer is supported from the rear of a tractor. The coupling connection is of the ball and socket type and is such that when the ball is lowered, the tractor can be driven away from the trailer, but the ball cannot be lowered until brakes have been applied to the trailer wheels. These brakes can also be applied manually from the tractor or the trailer or can be applied automatically when the trailer pushes the tractor. Fig 3 shows the front end of the trailer and the rear end of the tractor when only partly engaged, the auxiliary supporting wheels 22 being in operation. Fig. 5 shows a corresponding plan to a larger scale. Brakes on the trailer wheels are operated by a link 15 from a transverse shaft 51 on the front end of the trailer. The brakes are applied directly by a hand lever 54 on the trailer or by a hand lever on the tractor, the braking effort being then transmitted through a link 117, a cranked member 112 carried by shafts 113, 114 on the tractor, the vertical arm 108 of a bell-crank lever 107, 108 carried by the longitudinally slidable coupling member 76, a vertical pin 106 passing though the king pin 79 on the tractor, and the arm 57 of a ratchet sector 56 pivoted on the brake operating shaft 51. The ball coupling member 84 is prevented from moving downwardly by a stop 102 unless the trailer brakes have been applied. The stop is moved clear of the ball by a link 101 connecting it to a bell-crank-lever 99 having a shoe 109 which engages the crank 91. The crank 91 is, however, prevented from turning by means of an arm 122, shown also in Fig. 2, fixed on the shaft 92, unless the stop 120 carried on the spindle 113 has been moved clear of the end of the arm 122 by rotation of the spindle 113 to apply the brake. The brake is also applied automatically as the tractor and trailer move apart by means of a roller 59 on the ratchet sector 56 riding up the incline 60 on the rod 37 as the rod moves forwardly relatively to the trailer to lower the wheels 22. When the trailer pushes the tractor, the coupling members move forwardly against the springs 77, 78 and the trailer brakes are applied by engagement of the lever arm 108 with the crank 112.
