IPC: B60L11/00
Filed: 1924-07-28
Abstract: 222,448. M³ller, E. W. Sept. 26, 1923, [Convention date]. Boosting; regulation; systems of charging and discharging galvanic batteries.-The invention relates to electric traction systems in which storage batteries are carried upon the vehicles are charged either at stations when the vehicles are inoperative, or from a supply line during operation, they are also charged during braking by using the motors on the recovery principle. The system comprises a series motor c, battery band booter m mounted upon the vehicle, and a supply Ene a. During regenerative braking, the machine c acting as a generator is excited by the battery, the excitation being regulated by a rheostat d controlled by a servo-motor e. When the, speed has dropped to such a value that the regenerative braking is ineffective, a centrifugal governor d brings into action a hydraulic brake f. A small pump i also controlled by the governor and operated by the vehicle serves to charge the brake.. The battery can be charged while the motor c is running by a booster m driven by a shunt motor l, and having its exc tation varied by a rheostat n also controlled by :he servo-motor e. The Specification as open to inspection under Sect. 91 (3) (a) describes the invention with reference to a drawing differing from that occurring in the Specification as accepted. This subject-matter does not appear in the Specification as accepted.

Filed: 1970-04-15
Abstract: 1313422 Amylose HAYASHIBARA CO 15 April 1970 [15 April 1969] 18043/70 Heading C3U In a process for the production of low M.W. amylose by the hydrolysis of starch with α-1,6- glucosidase, starch slurry is liquefied at a temperature in the range of from 85 to 170 C. and the liquefied starch is rapidly cooled to a temperature in the range of from 50 to 60 C. and treated with an α-1,6-glucosidase in this temperature range to reduce the viscosity of the starch solution and to prevent retrogradation of amylose during subsequent hydrolysis of the starch with α-1,6-glucosidase. After treatment at a temperature within the indicated range, the resulting solution of reduced viscosity is cooled to a temperature of 40-50 C. at which the hydrolysis of the starch with α-1,6-glucosidase is completed. Additional enzyme may be added to the starch while at this temperature. Altogether, two or more α-1,6-glucosidases having different enzymatic actions and temperature affinities may be used. The starch may be liquefied by simple heating of the slurry to a temperature of 130-170 C. to a dextrose equivalent of 0À5-3 or by heating the slurry to a temperature of 85-100 C. in the presence of α-amylase. The final product after recovery and drying is typically a non-hygroscopic crystalline powder consisting of substantially pure amylose having a degree of polymerization of from 20 to 30.

Title: Electrostatic information storage
IPC: G11C11/23
Filed: 1955-06-28
Abstract: 796,347. Electric digital-data-storage apparatus. INTERNATIONAL BUSINESS MACHINES CORPORATION. June 28, 1955 [July 1, 1954], No. 18624/55. Class 106 (1). [Also in Group XL (a)] In a method of storing information in the form of electric charges on a dielectric target, the electron beam inspecting, reading and laying down the charge in an elemental area is first unblanked as a sharply focused beam and defocused whilst still impinging in the area before being blanked. The focus-defocus pulse generator 101 is connected to the electron lens of the storage tube 110. Blanking pulses from generator 106 are fed by gating means 104 to the control electrode G1, the dash pulses only being permitted when a positive signal is received from the signal plate 111 of the tube. A dash deflection generator 102 is connected in parallel with the horizontal deflection portion of voltage generator 100. Sample or strobe pulses are fed to gating means 104, which also receives information and read/write control. A modification of the circuit is described (Fig. 1, not shown). It will be seen from the diagrammatic explanation of Fig. 3, that when the beam impinges on a "dot" or positively charged area A, a negative signal D30 is released, the beam is focused for part of period t 0 -t 1 , and then defocused, thereby restoring the positive charge of the area. When a " dash " or negatively charged area B is impacted by the unblanked beam, a positive signal D31 is generated and a further dash-pulse D2a is gated to unblank the focused beam for a further period D21a, the dash deflection pulse simultaneously deflecting the beam so as to irradiate the immediately adjacent areas. The secondary electrons liberated at these areas pass to the original positively-charged elemental area and render it relatively negative, thus restoring the " dash " condition of the area. Specification 657,591 is referred to.

Abstract: 1,082,005. Automatic train control. SIEMENS A.G. May 4, 1965 [May 4, 1964], No. 18830/65. Heading B7N. In a railway signalling system in which information is transmitted to a train via conductor loops L, defining track zones 1, 2, which are energized from coded current transmitters (not shown), the conductor loop of zone 1 is terminated by a circuit including relay R which has a contact R1 in series with an impedance Z1 which with impedance Z2 forms the terminal impedance of the conductor loop of zone 2. Should coded current in loop 1 fail when a train is stopped at the junction of the two loops, relay R releases and opens the circuit to impedance Z1 whereby the current in the part of loop between the two impedances drops to zero and pick-up by the train of signals in the loop associated with section 2 is prevented.

Abstract: 590,365. Photo-electric control of machine tools. RICKENHAM, A. Nov. 15, 1943, No. 18959. [Class 40 (iii)] [Also in Groups XXII and XXIII] In a lathe or grinding machine in which a workpiece is machined to a given diameter in a number of successive working strokes (see Group XXII), the cutting tool at the beginning of a traverse passes a feeler gauge in contact with the work. The consequent movement of the feeler causes the rotation of a slotted disc 51, thus interrupting a beam of light passing from a source 54 to a photo-electric cell 53<1>, both of which are carried by a rotary arm 53. This causes the actuation of a presetting device determining the amount of infeed of the tool for the next traverse, the arm 53 being rotated with the movement of the presetting means until the light agains falls on the cell 53<1>.
