Title: Self-steering vehicles
IPC: G05D1/02
Filed: 1971-04-26
Abstract: 1342633 Floor cleaning machines ROBERT BOSCH GmbH 26 April 1971 [25 April 1970] 11346/71 Heading A4F [Also in Divisions  B7 and H4] An automatically controlled sweeper 13 includes a detector device 16 for detecting an obstacle in the path of the sweeper and a control device which, in dependence upon the position of an obstacle in the path of the sweeper as detected by the detector device, effects at least one change in the direction of travel of the  sweeper to avoid the obstacle. As described an automatic sweeping machine has a rotating brush 78, and wheels 48 driven by an electric motor 47, one pair of wheels 48 being steered by a steering device 50. The sweeper 13 has a bank of sensors in the form of electro-mechanical limit switches 36 to 45 along its front end, a sensor 49 at its back end, and sensors 53 and 77 at its sides. The sensors feed signals to a control device 46 which controls the motor 47 and the steering  device 50. In use the sweeper starts at point 14 and moves in a straight line until it reaches the opposite boundary at 15. The motor 47 is then reversed, and the sweeper moves back to point 14 where it is steered sideways by steering device 50 until it reaches point 17, separated from the original path by the width of the sweeper. This is repeated so that the sweeper covers the whole of the floor area. If an obstacle e. g. 11 is encountered the motor 47 is reversed and the sweeper returns to the boundary. If all the sensors 36 to 45 have been actuated by the obstacle the sweeper moves transversely by the width of the sweeper. Otherwise the sweeper is moved transversely by an amount corresponding to the width of the obstacle as detected by the sensors 36 to 45. The sweeper then moves forwardly until it passes the obstacle (detected by sensor 53) and then moves transversely behind the obstacle as shown in Fig.1. In a modification (not shown) the sensors may be in the form of optical, acoustic or magnetic transmitters and receivers. When the obstacles are in the form of depressions the boundaries of the depressions are defined by wires carrying alternating currents and the sensors are in the form of coils.

Classes 120(2) and 142(2) [Also in Groups VIII, XVI and XXIX] 8 A worm shaft 31 driving a take-up shaft 12 is itself driven by the excess of the oil drag between a member 40 on the shaft and a constantly rotating clutch member 47 over that between the member 40 and a stationary brake member 42, the parts 40, 47, 42 being immersed in oil. The member 42 is initially located at a predetermined distance from the member 47 by a screw 36. Thereafter, increase in take-up tension will increase the tendency of the worm gear 25 to shift the worm shaft 31 axially against the action of a spring 72 and so to move the member 40 away from the clutch member towards the brake member to reduce the nett driving torque and reduction of the tension will allow the Spring to return the shaft. The initial pressure of spring 72 may be adjusted by a screw 75 bearing a graduated thimble 77.

Title: Process for the manufacture of n-substituted formylhippuric esters
IPC: C07C233/45
Filed: 1945-05-05
Abstract: N-Substituted a -formylglycine esters of the general formula <FORM:0592461/IV/1> or the tautomeric form <FORM:0592461/IV/2> wherein R and R1 represent alkyl or aralkyl radicals and R2 an alkyl or aryl radical, provided that when R1 is an alkyl radical R2 must be an aryl radical or a straight chain alkyl radical of 1-4 carbon atoms, are manufactured by treating an ester of the general formula R2CO.NR1.CH2.COOR with an alkyl formate in the presence of an alkali metal alkoxide, and acidifying the product. The reaction is conveniently effected in absolute alcohol, in a dry inert solvent such as ether or benzene, or in a mixture of alcohol and dry inert solvent.  The esters used as starting materials may be made by treating an ethereal solution of the corresponding N-alkyl- or N-aralkyl-glycine ester with the appropriate acid chloride in the presence of an acid-binding substance, or by treating the hydrochloride of the N-alkyl- or N-aralkyl-glycine ester with the appropriate acid anhydride in the presence of the sodium salt of the corresponding acid.  In examples: (1) sarcosine ethyl ester hydrochloride is treated in suspension in ether with benzoyl chloride in the presence of sodium carbonate, and the resulting ethyl N-methyl-hippurate is stirred with ethyl formate and a solution of potassium in alcohol and ether, yielding ethyl N-methyl-a -formylhippurate; (2) ethyl N-benzylhippurate is similarly prepared from ethyl benzylaminoacetate and is similarly converted to ethyl N - benzyl - a  - formylhippuric ester; (3) sarcosine ethyl ester hydrochloride is warmed with acetic anhydride and sodium acetate, and the resulting N-acetylsarcosine ethyl ester is treated with ethyl formate as in (1) to produce a  - formyl - N - acetylsarcosine ethyl ester; (4) the benzoyl chloride in (2) is replaced by caproyl chloride, yielding a -formyl-N-caproyl-N-benzylglycine ethyl ester. Sodium methoxide is also specified as a condensing agent.

Abstract: 1298411 Seaming non-metallic sheet material BONDIT CORP 11 March 1970 [12 March 1969] 11599/70 B5K  In apparatus for joining sheet material 1a, 1b by interfeeding a dry filamentary adhesive 8 between the materials in the areas thereof to be joined and applying heat and pressure to effect joining, the heating energy being applied to the adhesive 8 being dependent upon the rate of travel of the material 1a, 1b so that the temperature of the adhesive is substantially constant. As shown, overlapping or superimposed sheets 1a, 1b with a dry monofilament thermoplastic adhesive 8 therebetween pass between rolls 2a, 2b, electrodes 3, 4 and rolls 5a, 5b and are rewound on a reel 6. Belts 13, 14, preferably coated with polytetrafluoroethylene, pass around the rolls 2a, 5a and 2b, 5b, respectively. The electrode 3 is grounded and the electrode 4 is connected to a RF generator 10. The electrodes 3, 4 compress the sheets 1a, 1b the adhesive 8 and the belts 13, 14 with a force determined by a gap control 9. The speed of the sheets 1a 1b is determined by a motor 20 whose shaft 21 is connected to the reel 6 and, also, if desired, to the rollers 5a, 5b. The speed of the motor 20 is controlled by a controller 22 which may comprise an autotransfer whose voltage output is determined by the position of a linkage 23 connected to a foot pedal 24. The linkage 23 is connected to a controller 25 which applies the input power to the generator 10. Thus, the position of the pedal 24 determines both the speed of the motor 20 and the output power of the controller 25 so that as the motor speed increases or decreases the heating energy applied to the adhesive 8 increases or decreases to prevent under-heating or over-heating, respectively, thereof. The controller 25 is described in detail, Fig. 2 (not shown).
