Abstract: 202,804. Nunn, L. S., and Dixon, G. T. July 5, 1922. Guarding against unauthorized use.-Relates to apparatus in which a bolt adapted to engage the steering tube of a motor vehicle or bicycle and prevent operation thereof, is held in the locked or unlocked position by a series of code rings concentric with the bolt. The locking bolt works in a sleeve 9 having an integral part 1 which fits halfway round the steering column and is clamped thereon by a U-shaped band 2, the clamping nuts being hidden by a shield 7 which cannot be removed when the code rings are in position. The shield also covers a pin 14 which passes through a slot 12 in the bolt and allows movement thereof between the in and out limits. Lugs 11 on the bolt pass through a longitudinal slot 13 in the sleeve 9 and engage either inside or outside the interior flanges of code rings so as to lock the bolt in or out of engagement with the steering shaft 15. An additional ring 19 secured to the end of the sleeve 9 prevents longitudinal movement of the code rings.

Abstract: 185,079. Triumphatorwerk. Aug. 22, 1921, [Convention date]. Multiplying and dividing apparatus.-Relates to calculating-machines of the pin-wheel and cam-disc type having a laterally movable totalizing-counter carriage whereby calculations according to the four rules may be made, and particularly to key-operated escapement arrangements for affecting either unitary or unlimited movements of this carriage in either direction. Pivoted to the middle wall of the totalizing- ccunter carriage 1 is a double-armed lever having a finger 3 to engage slots 4 in the base-plate of the machine. The end 14 of this lever is engaged by a hook 23 on a second lever 12 pivoted on a third lever 18. This lever 18 turns upon a pivot 17 mounted on the carriage, and is provided with a step-by-step key 9. On depression of the step-by-step key 9, the end 14 is pulled down by the hook 23 so that the finger 3 is released from the slots 4, and the carriage may be moved to right or left through a distance of one space, whereupon the pawl 24 on lever 12 is tripped by one of a number of pins 27 upon the stationary base of the machine, so that the end 14 is released from the hook 23, thus allowing the finger 3 to engage in the next slot 4. When the step-by-step key 9 is released a spring 26 returns the hook 23 into engagement with the end 14. A free-movement key 5 is provided on the double-armed lever in order that the carriage may be moved through any distance to right or left.

Title: Brake operating mechanism for motor vehicles
IPC: B60T13/06
Filed: 1929-06-17
Abstract: 313,853. Eclipse Machine Co., (Assignees of Ragan, F. H.). June 16, 1928, [Convention date Applied by running axle or wheel. - Brake operating mechanism for effecting the application of the brakes of motor vehicles by a rotating part of the vehicle, comprises a nut member normally rotating with a screwed shaft which may be driven from the driving shaft of the vehicle and means for braking the nut member to cause it to travel axially, such movement in either direction applying the vehicle brakes. The screwed shaft 32, mounted in an extension 33 of the transmission casing 12 is driven by the gearing 30, 31 from the transmission shaft 29 connected to the drive shaft 13. A nut member 37 is carried by the shaft 32 and engages by a radial and thrust bearing 43 a thrust shaft 39 arranged to engage directly or by a lever 52 pivoted at 53 to the casing, a lever 47 pivoted to a fixed member 49. Rotation of the shaft 39 is prevented by the engagement of an arm 45 thereon with a fixed rod 46. The lever 47 is connected by a link 50 to an arm 51 secured to a rock shaft 17 connected by the members 20 - - 25 to the vehicle brakes. A pedal 55 freely mounted on the shaft 17 is connected by a link 56 and through a spring 61 to a cranked lever 58 engaging an arm 65 on a rock shaft 64 mounted in the casing. The shaft 64 carries a plate 66 in contact with a roller 67 on plate 68 mounted free to move longitudinally and laterally in the casing, and having secured thereto one end of a brake band 71 passing around the nut member 37, the other end of the band being fixed. When the pedal 55 is depressed, the band 71 is tightened on the nut member 37 by the connections 56 - - 68, thus causing axial movement of this member and the application of the brakes through the thrust shaft 39 and shaft 17. The lever 47 is moved by the direct engagement of the shaft 39 or through the lever 52 according to the direction of rotation of the shafts 32, 29, the brakes being thus applied irrespective of the direction of travel of the vehicle. The pressure applied to the brakes is dependent upon the pressure applied by the pedal 55 to the brake band 71. The pedal carries a roller for engagement with the lever 51 whereby the brakes may be applied by the direct effort of the operator if the power device fails, the spring 61 yielding to permit this.

Title: Improvements relating to monoazo dyestuffs derived from diphenyl ether and their use
Inventor: SCHMID OTTO
IPC: C09B29/30
Filed: 1958-06-12
Abstract: The invention comprises dyes of formula:-  <FORM:0878129/IV(c)/1> where D is a residue of a naphthylamine sulphonic acid coupled #s to the amino group, R is a tertiary sulphonamide group the nitrogen substituents of which together have at least 4 carbon atoms and the individual substituents have at most 7 carbon atoms, and A and B may contain substituents which no not dissociate in neutral water.  The dyes are made in conventional fashion from appropriate diphenyl ether diazo and D coupling components. Coupling is effected in an acidic medium.  Indicated substituents for A and B are alkyl, alkoxy and acylamino groups e.g. methyl, tert. amyl, butoxy, and acetyl-, benzoyl- and carbobutoxy-amino groups, and triazinylamino groups. Further substituents indicated for B are carboxylic and sulphonic acid amide groups derived from secondary amines, sulphonic acid aryl ester groups or alkyl or aryl sulphonyl groups.  The diazo component may also contain halogen atoms, e.g. bromine and trifluoromethyl. The N-substituents are generally saturated and may be acyclic or isocyclic or together with the N atom, and possibly other hetero atoms, may form a heterocyclic ring.  Preferred dyes are those containing sulphonic acid dialkylamide groups, especially when one of the alkyl residues is a cyclohexyl group and particularly dicyclohexylamide groups.  The N sulphonamide atom may be substituted with one saturated radical and one phenyl group e.g. sulphonic acid- N-ethyl- or -cyclohexyl-phenylamide groups. Preferably primary aminonaphthalene sulphonic acids are used as coupling components although the amino group may contain alkyl, aralkyl, cycloalkyl or phenyl substituents.  The coupling components may contain halogen, hydroxy or alkoxy substituents. Particularly preferred coupling components are 2-aminonaphthalene- and 2-amino- 8-naphtholsulphonic acids which are free from further substituents.  The dyes colour silk, wool and synthetic polypeptides in orange, red and blue shades. Examples are provided of the preparation of the dyes and their use in colouring processes.

Title: Improvements in high frequency electric signalling systems
IPC: H04B7/155
Filed: 1919-07-29
Abstract: 142,371. Western Electric Co., (Western Electric Co.). July 29, 1919. Wireless telegraphy and telephony.-In a method of repeating modulated high-frequency waves from one station to another, the modulated wave of frequency P + a, (where P is the carrier frequency and a the signal or speech frequency) received at the relay station is combined with locally generated oscillations of a different high frequency Q so as to change the carrier frequency to P Œ Q; the modulated energy of frquency P Œ Q + a transmitted from the repeating-station does not therefore affect the receiving aerial at that station, " singing " being thus prevented. In the system shown in Fig. 1, the energy received by the aerial 1 (tuned to the frequency P + a) and oscillations from generator 2 are combined by the modulator 3, the output circuit of which is connected through amplifiers 18, 21, tuned to one of the frequencies P + Q + a, to the transmitting-aerial 25. If the suppression of the unmodulated carrier wave at the transmitting-station is incomplete, beats of signal fre. quency a will be present in the modulator output circuit and can be heard in the telephone 13. The carrier frequency may be raised at one repeating-station and lowered at another. Specification 102,503 is referred to.

Title: Improvements in radiation gauge
IPC: G01N23/16
Filed: 1959-06-03
Abstract: 886,634. X-ray gauging systems. GENERAL ELECTRIC CO. June 3, 1959 [June 5, 1958], No. 18949/59. Class 40(3). The invention relates to X-ray apparatus for determining the density or thickness of a sample. According to the invention the intensity and penetrating quality of the X-rays in such apparatus is controlled by using a pair of detectors to measure the radiation intensity before and after the test sample and from these measurements to obtain a control signal for the source. Fig. 1 shows one layout of a gauging system in which radiation from an X-ray tube 12 is emitted as a beam 16 passing through a first intensity detector D1, a test sample of unknown thickness X and a further intensity detector D2. The beam continues through a thin fixed absorber of known small thickness F to a final detector D3. Considering first detectors Dl and D2 it is arranged that D1 is of less sensitivity than D2 by a factor K and the corresponding detector output currents I 1  and I 2  are applied with opposite signs to a summation circuit L1 whose ouput is applied as a control signal to a network C1 in the anode-cathode power supply of tube 12. The arrangement functions to maintain the beam intensity at D1 a fixed multiple of that at D2. The output of either detector (that of Dl as shown) may be amplified and applied to a meter G to indicate the thickness of the test sample The detectors D2 and D3 are preferably of identical sensitivity and their outputs are applied in opposition to a summation circuit L2 together with a fixed input I D  to give an output I 2 -(I 3 +I D ) which is applied to network C2 to regulate the intensity of the X-ray beam. It is explained with reference to Fig. 2 (not shown) that detector D1, provided that it is in the beam, need not be between the source and the sample and, likewise, the radiation passing through the fixed absorber to D3 may come direct from the source and not through D1, X and D2. In a simpler embodiment, Fig. 3 (not shown), the fixed absorber and detector D3 are not used and the control signal for network C2 is derived in dependance on the voltage drop across a fixed resistor in the anode circuit of the tube 12.

Abstract: 969,084. Bottling. GRAHAM-ENOCK MANUFACTURING CO. Ltd. May 7, 1963 [May 17, 1962], No. 19014/62. Heading B8T. Prewashed bottles are introduced at 2 to a stepwise moving endless conveyer 3 in a housing 1 and are subjected to a preliminary flushing with hot water at a zone 6 by nozzles 7 before passing to a sterilizing zone 8 where they are subjected to a series of steam fillings from nozzles 9. The latter may be in laterally disposed rows aligned with similarly disposed rows of bottles on the conveyer, and the arrangement is such that during each dwell of the conveyer the nozzles are raised by a framework 10 into engagement with the bottle mouths, whereupon valves are automatically opened and steam is supplied. Movement of the conveyer between each dwell carries the bottles a distance equal to that between adjacent nozzles. The condition of the steam may be varied at different stages, i.e. at stage 11 it may be wet and at stage 13 dry. From the sterilizing zone the bottles, whilst being retained in a sterile ambience, are allowed to drain whilst in an inverted position, and pass to a filling station 14 and then to a capping and scaling device 17 before being discharged at a position 4. The filling, capping and sealing operations take place during conveyer dwell periods. To maintain a sterile ambience, sterile air under pressure is introduced into an area 20 via a duct 21. The machine includes a hot water and steam con densate collection tank 23, and an opening 22 for an operator, normally closed by a door.
