Title: Compound steering transmission systems for fully tracked vehicles
IPC: F16D67/02
Filed: 1975-03-03
Abstract: 1489317 Differential gears; variable-speed gears ZAHNRADFABRIK RENK AG 3 March 1975 [15 March 1974] 8754/75 Heading F2D [Also in Division B7] In a transmission system for tracked vehicles in which sprockets 6, 6<SP>1</SP> are driven by an engine 1 through a torque converter 2, gearing (including reverse gear) 3, and respective differentials 4, 4<SP>1</SP>, and in which steering is effected by drive superimposed on the differentials by a shaft 30 connected through planetary trains 35, 36, 37, 38 a steplessly variable drive, e.g. an hydraulic pump-motor combination, 11, 12, and gearing 10, with a primary shaft 7 and/or a secondary shaft 8, steering control means is provided which sequentially controls the steplessly variable drive and brakes 32, 33, 34 governing the planetary trains 35 ... 38. Fig. 6 shows the steering control means positioned for straight running, a linearly movable member 40, or alternatively a rotary member, being positioned centrally by a steering wheel 39 so that a cam 42 positions a valve 44 to apply the brake 32, a cam 43 is clear of valves 45, 46 so that the brakes 33, 34 are released, and a cam 41 sets the pump 11 for zero displacement. In this condition, because both the ring gear 28 and the sun 26 of the train 38 are held stationary by the brake 32 and the motor 12, respectively, the shaft 30, on which the planetary carrier 29 is mounted, remains stationary. Displacement of the member 40 from its centre position adjusts the pump progressively to its maximum displacement in either sense to cause rotation of the shaft 30 in response to rotation of the sun 26 by the motor, whereafter further displacement of the member 40 causes application of one of the brakes 33, 34 by the cam 43 and release of the brake 32 so that rotation in an appropriate sense is imparted through the gearing 10 to the carrier 22 of the train 37 where it is compounded with the rotation of a sun 23 on the shaft of the motor 12 to increase the speed of rotation of the shaft 30 as, in response to continued displacement of the member 40, the pump is adjusted by the cam 41 back through zero displacement to its maximum displacement in the opposite sense. Also described are means (not shown) for reducing the quantity of fuel supplied by an injection pump to the engine 1 in response to either excessive pressure in the circuit of the pump-motor combination 11, 12 or excessive speed of the shaft 30. (For Figure 1 see next page.)

Title: Framing in data handling apparatus
IPC: H04J3/04
Filed: 1975-03-05
Abstract: 1488939 Multiplex frame synchronization WESTERN ELECTRIC CO Inc 5 March 1975 [11 March 1974] 9076/75 Heading H4M In a system for maintaining frame synchronization in an ultra high speed time division multiplex communication system in which data frames are separated by interleaved framing bits in a predetermined framing pattern, prior art problems caused by the need for high speed logic are reduced. The high speed digital bit stream multiplex input is unconditionally (or non synchronously) divided at 211 into two bit streams which are applied to a separator 210 which conditionally divides each applied bit stream into four lower speed bit streams in accordance with phased control pulses from a divider 214. These pulses are arranged to correspond with the multiplex format, in which the frame contains 196 bits commencing with SS bits representing stuffing information, 96 channel bits from the six channels interleaved in turn, PP bits representing parity and a further 96 channel bits. Phased control pulses # 1 -# 3  correspond with channels, while # 4 , at much lower frequency, correspond with synchronizing (stuffing and parity) bits. Of the eight bit streams produced by the separator, six are fed to a switch 217 which has six outputs each corresponding to one multiplex channel. The other two bit streams which should represent synchronizing information are fed to a framing detector 215. This inspects the received streams and if the framing pattern is not detected, applies signals to repetitively shift the phase position of the pulses from the divider 214 and thus the division process of the separator 210 until the framing pattern is detected. Depending on which of its inputs provides the framing pattern, the framing detector 215 controls the mode of the switch 217 such that each multiplex channel is supplied to the proper output. A gating logic circuit 216 receives as inputs in second mode the pulses from the sixth flip-flop 231 in the separator 210, pulses from the synchronizing flip-flop 232 and the # 4  divider pulses. In the second mode, most channel 1 bits appear on the output of 231 but some appear on 232 and these must also be routed to the channel output 01 of the demultiplexer. Some framing bits appear on 231 and these must be routed to the framing detector. The framing detector detects either the sync. pattern in the output from 219 or 221-these patterns may differ. The detector has to be able to respond to any of N patterns, N being the unconditional division ratio, since it is not known whether the unconditional divider will initially pick up odd or even channels at 219, 221. The Specification indicates that the procedure may be adapted to any system where an initial unconstrained division by N is performed and where there are Q multiplex channels.

Title: Improvements in the treatment of tars
IPC: C10C3/02
Filed: 1932-03-30
Abstract: Tar is treated to prevent oxidation, and render it more suitable for use in road making by adding nitrogenous bases and polymerized triglycerides, with or without asphaltic hydrocarbons, and heating the mixture to above 400 DEG  F. until the desired viscoscity has been attained.  Suitable additions are organic bases, bone tar, fatty acid pitch, or vulcanized marine oil, or a mixture of native asphalt and triglycerides.  A current of air may be passed through the mixture during the heat treatment.  Acrolein is produced, and forms condensation products with the tar acids.  In an example 2,500 gallons of crude tar were heated in a closed vessel with 3 1/2 per cent fatty acid pitch, and 1 1/2 per cent bone oil, comprising 10 per cent nitrogenous bases, 50 per cent triglycerides, and 40 per cent hydrocarbons.  The treatment lasted 36 hours, the temperature reaching 450 DEG  F., and 400 cubic feet of air per 2,000 gallons of tar were passed over the surface of the mixture which resulted in the formation of a plastic pitch.  The Specification as open to inspection under Sect. 91 refers also to the use of tar products. This subject-matter does not appear in the Specification as accepted.
