Title: Improvements in brake actuating systems including anti-skid control units
IPC: B60T8/42
Filed: 1966-05-13
Abstract: 1,108,123. Anti-skid braking system; warning devices. GRAUBREMSE G.m.b.H., and TELDIXLUFTFAHRT AUSRUSTUNGS G.m.b.H. 13 May, 1966 [14 May, 1965], No. 21311/66. Headings F2E and F2F. An hydraulic braking system comprising an anti-skid brake control unit 1 having a fluid supply pipe 4 connected to a brake operating cylinder 5a, 5b and a normally closed exhaust pipe 3, the control unit interrupting the supply pipe to the cylinder and for opening the exhaust pipe in the event of the wheels locking, is characterized by further means which inactivate the operation of the anti-skid device before the pressure generating member 19 reaches the limit of its travel. The further means may comprise a reservoir 26 having a movable wall 27 and connected to the exhaust pipe 3 and through a non-return valve to the supply line 2. The maximum volume of the reservoir is less than the maximum volume of output of the master cylinder; hence before the master cylinder reaches the limit of its travel the reservoir wall 27 will have reached position 27a and no further exhausting of cylinder contents through pipe 3 can be achieved by the control unit when operated by the skid sensor 13. The reservoir can be of a bellows form. In a modification (Fig. 1, not shown), the master cylinder pedal is arranged to open the electrical circuit between unit 1 and sensor 13 when the pedal nears the end of its travel. In a further modification, where an air operated brake servo is provided with a lever indicating the position of the piston, the contact may be associated therewith. Warning devices.-Switch means and warning devices (not shown) may be provided to inform the driver that the master cylinder has reached its limiting position.

Title: Improvements in or relating to dyestuff intermediates; amino-nitrobenzene-sulphonic acid fluorides
Filed: 1953-12-21
Abstract: The invention comprises compounds of formula <FORM:0764309/IV(b)/1> wherein X is a hydrogen or halogen atom or a lower alkyl, lower alkoxy, trifluoromethyl or nitro group (lower denotes having not more than four carbon atoms).  The compounds may be prepared by reacting in aqueous medium the corresponding sulphonic acid chlorides with salts of hydrofluoric acid.  The sulphonic acid chlorides are prepared by reacting the corresponding acid with for example phosphorus oxychloride.  The reaction is advantageously carried out in aqueous medium at elevated temperatures, such as 100 DEG  C., using an alkali metal fluoride or an acid salt or complex compound thereof.  When X is hydrogen, the resultant 1-amino-4-nitrobenzene-2-sulphonic acid fluoride may be treated with a halogenating agent.  The compounds are used as dyestuff intermediates.  In examples: (1) a 1-amino-4-nitrobenzene-2 -sulphonic acid chloride having in the 6-position a hydrogen or chlorine atom or a methyl, methoxy, trifluoromethyl or nitro group is reacted with sodium fluoride; (2) 1 - amino - 4 - nitrobenzene - 2 - sulphonic acid fluoride is mixed with hydrochloric acid, a solution of sodium chlorate is added and on dilution with water 1-amino-4-nitro-6-chloro-benzene-2 -sulphonic acid fluoride is precipitated.  1 - Amino - 4 - nitro - 6 - methylbenzene - 2 - sulphonic acid. This compound is prepared by treating 1-amino-4-nitro-6-methylbenzene at 120 DEG  C. in tetrachloroethane with chlorosulphonic acid.  1 - Amino-4-nitro-6-trifluoromethylbenzene-2-sulphonic acid.  This compound is prepared by reacting 1 - chloro - 4 - nitro - 6 - trifluoromethyl - benzene at 60 DEG  C. with oleum and treating the resultant 1 - chloro - 4 - nitro - 6 - trifluoromethyl - benzene -2-sulphonic acid at about 130 DEG  C. under pressure with ammonia.

IPC: G01N29/024
Filed: 1970-05-04
Abstract: 1291181 Sound velocity measurement; ultrasonic couplings NUSONICS Inc 4 May 1970 [27 Feb 1970] 21354/70 Headings H4D and H4J Apparatus for measuring the velocity of sound in a fluid having at least one acoustic transducer and at least one reflector immersed in the fluid such that the sound path between  transmission and reception is invariant wherein, the frequency of the transmitted pulses is varied such that the echo pulse is received a predetermined time before the transmission pulse. Ultrasonic transmissions from ceramic transducer 24 are triggered by pulses from a divide-by-eight circuit 32 driven by oscillator 28. The reflected pulse is detected and compared in amplitude with a reference V r1 . The error voltage is used to adjust the transmitted pulse amplitude which is measured to determine the attenuation in the fluid. The position of the received pulse is compared to the position of the transmitted pulse in logic 50 and an "advance" or "retard" signal is produced on lines 52, 54. These produce a signal from detector 56 which is compared with reference Vr 2 . The error voltage is used to increase or decrease the oscillator 28 frequency until the received pulse is positioned at a predetermined point in the transmitter pulse period. Counter 60 records the frequency of the oscillator which is proportional to the velocity of sound in the fluid. Detector 38 and threshold circuit 48 are both gated by signals from logic 42 in order to avoid detecting the transmitted pulses. The "advance" or "retard" signal is monitored by detector 62 which is connected to indicator 64 which lights a lamp indicating thestate of the apparatus. The probe 24 is constructed with a transducer and reflector on a mounting, the coefficients of expansion of the materials involved being chosen such that the sound path length is constant with change in temperature. The system may be used for measuring properties of flowing or static liquids and may use two transducers instead of one.

Abstract: 1,021,635. Unstacking plate-type press filters. SOC. ANON. DES FONDERIES ET ATELIERS L. CHOQUENET. May 25, 1964 [May 31, 1963], No. 21460/64. Heading BID. An unstacking apparatus for a stack of filter plates comprises linked, pivotal dogs 22 and 23 connected rigidly via crabs 10 to chains 3 on either side of the stack which engage catches 9 on the plates and move them one by one from the remaining stack. On either side of the stack each dog 22 is caused to be retracted on encounter with a catch 9 when chain moves in direction of arrow F 1  while the dog 23 is extended and bears against the other side of the catch (Fig. 2), so causing the chain to halt. The chain is then moved in direction F 2  and in response to a spring 31 mounted on the pivot 16 of dog 22 the dog 23 moves into abutment with a square boss and moves the catch on the front plate in the direction away from the stack The cycle is then repeated to remove the next plate. The innermost turn of each spring 31 is retained in a slot 28, Fig. 4 (not shown), in the pivot head 16 while the outermost turn of the spring is anchored about a peg 34 welded into dog 22. Each crab consists of two side members 14 and 15 and the pivot is provided with a stub 32 which engages a slot 33 formed in the side member 14.

Title: Improvements in vehicle detecting arrangements suitable for use in traffic control systems
Inventor: RANGE ALAN LESLIE
IPC: G08G1/02
Filed: 1949-08-18
Abstract: 673,862. Road signals for controlling traffic. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd. Aug. 10, 1950. [Aug. 18, 1949] No. 21472/49. Class 118 (ii). A unidirectional traffic detector circuit includes two sets of contacts closed in succession in response to the passage of a vehicle over the detector, the contacts first closed by a vehicle proceeding in the right direction completing a circuit for the detecting relay in series with a capacitor and the contacts first closed by a vehicle proceeding in the opposite direction completing a low resistance shunt round the relay. With this arrangement, if the latter contacts are closed first the relay is not operated, and if the circuit for the relay is maintained closed, as the result of a fault say, only momentary operation of the relay is produced. The Fig. shows the circuit employed in a system the general arrangement of which is similar to that described in Specification 541,658. Contacts ARC, AFC are associated . with the phase A detector and close in succession on the passage of a vehicle. Relay AR is the detector relay, operating from the charging current in capacitor QA when AFC closes and locking over its lower winding. The subsequent closure of contact ARC shunts the relay with a low resistance RA2 but it remains held over its lower winding. The arrangement is unidirectional, since if ARC closes first condenser QA is charged rapidly via RA2 and the relay is not operated by the subsequent closure of AFC. Relay AP (not shown) is operated when the cam shaft reaches the vehicle extension position after a demand has been put in by the road relay and remains operated until the same position is reached after the phase in question receives right of way. Relay AS (not shown) operates during the green and subsequent amber period. Upon a vehicle closing contact AFC relay AR operates and locks, contacts not shown putting in a call to transfer right of way when the demands of. other phases allow. Upon right of way being transferred, relays AP and AS operate, relay AR is released and detector contacts AFC, ARC are transferred to detector relay EX which is connected in a circuit similar to that of relay AR but without a locking winding. The relay accordingly operates at each operation of the detector and secures repeated extension of the right of way period up to a maximum value. If a fault occurs such that AFC and ARC are closed permanently, relay AR operates normally to obtain right of way but when the detector contacts are transferred, relay EX operates once only so that one extension period only is provided. Contacts AFC, ARC may be pneumatically operated from a tread member provided with two longitudinal cavities of the type shown in Specification 512,836, [Group XXXVII].
