Abstract: 252,035. Imray, O. Y., (International Motor Co.). Dec. 8, 1924. Universal joints.-In shaft couplings of the kind in which rubber or like non-metallic yielding material is interposed between cooperating vanes or the like, on inner and outer cylindrical members secured respectively to the shaft portions, blocks of rubber or the like of subtsantial size are interposed under initial compression and are so secured that portions thereof are unrestricted whereby flow of the yielding material may take place when the two shaft portions are not in axial alignment. Specification 106,062 is referred to. In the form shown, similar couplings are fitted at each end of a section b of propeller shoft supported in anti-friction bearings d carried by hangers e secured to transverse frame members e<1> of a motor chassis. Rubber blocks f are arranged under compression between vanes k<1> extending inwardly from an outer annulus k secured by bolts i to a spider b<1> on the shaft b, and outwardly extending vanes h<1> on an annulus h secured by bolts g to a flange a<1> on a splined hub a carried by the other shaft section. The blocks f are confined on one side by seatings k<2>, h<2> formed integrally with the annuli and on the other side by the flange a<1> and a ring l bolted to the outer annulus k. The shaft section b may extend within the annulus h and carry a self aligning ball bearing m disposed at the centre about which the relative angular movement of the shaft sections takes place.

Title: Process for making improved industrial gum
IPC: C12P19/06
Filed: 1963-07-25
Abstract: A water-soluble gum is made by adding a micro-organism of genus Xanthomonas to an aqueous culture medium containing farinaceous nutrient material containing buffer salts and having a C/P (carbohydrate/protein) ratio of 7/1 to 15/1 , initially adjusting the pH to 7-8.5, mechanically agitating and aerating the mixture, and effecting fermentation of the culture medium at 21-35 DEG  C., to produce a solution of the gum after fermentation in a viscosity range of 4,000-12,000 centipoises measured at 28 DEG C. and 30 R.P.M. in a final pH range of 5 to 7.  Specified nutrients are sorghum, soy, corn, barley and oat flours.  The culture medium may also contain an antifoam agent, a buffer and added organic nitrogen, e.g. soy flour, meat extract, amino acids and casein.

Filed: 1961-08-17
Abstract: 962,740. Gearing elements; cams. HOOVER Ltd. Aug. 16, 1962 [Aug. 17, 1961], No. 29752/61. Headings F2D, F2K and F2Q. A cam mechanism for actuating a cam follower in the form of a pivoted arm 41 carrying a roller 40 comprises a disc 28 driven by a reversible rotary shaft and carrying a dog 33 pivotally mounted on a pin 30 so as to be rocked by its engagement with the cam follower roller 40 between two positions, in each of which it presents to the cam follower a gradually rising leading face and a steeply falling trailing face. The disc 28 is secured to the end face of a wormwheel 25 which has a cut out keyhole-shaped portion 29 forming abutment surfaces 37 for the dog 33. For driving a timing disc 11 for the programme of a dish washer, the arm 41 carries a spring-pressed pawl 46 which engages the toothed periphery of the disc 11 and is urged in an anti-clockwise driving direction by a spring 43. For either direction of rotation of the disc 28, the engagement of the dog 33 with the roller 40 causes the pawl 46 to move back one tooth of the disc 11 and thence, under the influence of spring 43, to index the timing disc 11 forward one step, the pawl 46 then abutting a stop 60. A spring stop 49 prevents backrunning of the disc 11. The cam disc 28 is driven from a reversible electric motor 10 through two trains of worm and worm-wheel gearing 16, 18, 20 and 25. The trains are simi. lar and the teeth of each worm-wheel extend parallel to its axis so that the axis of a fixed shaft 26, on which the worm-wheel 25 rotates, is parallel to the motor shaft 15 which carries the worm 16.

Title: Warning system for vehicle drivers during long drive
IPC: G07C5/00
Filed: 1976-07-19
Abstract: 1531062 Electronic timed alarms NISSAN MOTOR CO Ltd 19 July 1976 [18 July 1975]  29936/76 Heading G3T In a warning system for a vehicle driver, elapsed time since the start of the vehicle is electrically measured by an integration circuit. A warning signal is generated when the elapsed time reaches a limit. The rate of integration or the time limit is changed according to a clock which distinguishes day and night periods. As shown in Fig. 1, a voltage source 3 is connected to an integrator 2 by a switch 4 which is closed by the driver when a vehicle is started. The steadily increasing voltage output from the integrator 2 is fed to one or other of a pair of comparators 5, 6. When a corresponding reference voltage level V 1  or V 2  is reached, a signal is supplied through an OR gate 8 to actuate an alarm 9. A clock 1 operates a switch 7 according to the time of day such that one of the comparators 5, 6 is used during daytime and the other comparator is used at night. The reference voltages V 1 , V 2  are chosen so that the time taken to reach the limit and operate the alarm is shorter during the night. Other embodiments, some using binary counters and digital comparators, are described with reference to Figs. 2-8 (not shown). The switch 7 may be operated by reed contacts closed by a magnetic element rotating with an hour drum on a digital timepiece, Figs. 9, 10 (not shown).
