Title: Improvements in or relating to phonographic record changers
IPC: G11B17/16
Filed: 1964-10-12
Abstract: 1,072,989. Spindle adaptors. V-M. CORPORATION. Oct. 12, 1964 [Nov. 22, 1963], No. 41571/64. Heading G5R. An adaptor spindle which permits a conventional record changer with small diameter spindle to accommodate large hole records comprises a housing 26 which is substantially rectangular in cross-section, record locating roller bearings 102, 104 which reduce friction between the housing and the record on the turntable 24 and a record support shelf 66 and record separator blade which are operated by the record change mechanism of the conventional player. The housing, which has an upper offset portion which assists in retaining the records horizontally on the shelf 66, slips over the small diameter spindle 22 and is retained in its vertical position by the seating of the upper end of the offset part 38 of the spindle against the base 64 of the adaptor sleeve 60. Actuation of the record change mechanism moves spindle 42 upwards so that actuator 46 is moved vertically and counter-clockwise and moves the separator outwardly against the action of spring 84 to separate the lowermost record from the remainder of the stack R. Movement of the separator actuates a toggle 90 which moves the shelf 66 inwardly against the action of spring 74 and the lowermost record drops on to the turntable. The springs return the separator and shelf to their original condition. The shelf can be cammed inwardly to remove records from the turntable. A second embodiment, Figs. 7-9 (not shown) describes an arrangement using three roller bearings. The centre portion of the turntable is recessed to accommodate the lower portion of the adaptor.

Title: Method and apparatus for the continuous production of wort as hopped wort
IPC: C12C7/16
Filed: 1961-11-23
Abstract: In the continuous production of wort, e.g. hopped wort, a continuously prepared mash is filled uninterruptedly between filter walls 2, 3 of a tower 1 and as the mash moves downwards the first wort is drawn off through the filter walls, and the resulting spent grains are sparged with water through the filter walls and <PICT:0942623/C3/1> are discharged at the lower end of the tower into a conveyer 9 covered by a perforated screen (not shown). The pressure, direction and succession of flow of the sparging liquor through the various chambers 11, 12 and 13 of the tower may be varied; the liquor may be repeatedly passed through spent grains at various levels until a desired concentration of liquor extract is reached. The spent grains discharged from the tower may be admixed with sparging water, mash or wort, and recycled. The tower may incorporate heating elements with temperature feelers, and restricted orifices and/or pressure booster pumps may be interposed between the chambers for controlling the pressure of liquor between them.  It is stated that the spent grains may be compacted or loosened by movement of the walls of the tower and of its discharge passage towards or apart from one another, employing inflatable seals in conjunction with hinged walls, and that the rate of movement of the mash and spent grains may be varied by varying the inclination of the walls of the tower or of the tower as a whole.  The thickness of the cake 8 of spent grains between the filter walls may, for example, amount to 15-40 centimetres.

Title: Electronic tracking control for vehicles with hydrostatic transmissions

Filed: 1976-10-22
Abstract: 1514101 Automatic speed control SUNDSTRAND CORP 22 Oct 1976 [3 Nov 1975] 43842/76 Heading G3R The wheels or tracks of a vehicle are driven, through a hydrostatic transmission, at the same speed to move the vehicle in a straight line, or at a pre-set differential speed; to move the vehicle along a curve. Pulses at a frequency dependent upon the speed of each wheel or track are phase compared to form a control for the hydrostatic transmission. In the embodiment, magnetic sensors MPU1, 2 provide signals at a frequency proportional to respective track speeds, which signals are converted to pulses, of one polarity only, that are phase compared at 326. Any speed error, on line 332 or 334 of the comparator according to which speed is higher, passes through inverters 336, 338 to a differential integrator 346 that forms a voltage dependent upon the difference and at a polarity indicating which speed is higher. Provided pre-set threholds are exceeded, the output of the differential integrator is used to turn on solenoid valves 82 or 84, according to the output polarity, thus allowing hydrostatic fluid to pass from a pump to a track drive motor, so as to drive the vehicle in a straight line. Alternatively, a bias from adjustable potentiometers 408 or 416 may be applied to the differential integrator to drive the vehicle along a curve. If any other turning operations are selected by the driver, the output of the differential integrator is reduced to zero by a contact of relay 396, which shorts feedback capacitor 348 on the amplifier 346. This inhibits the system which would otherwise try to correct the turning motion. When this turning mode is complete, relay 396 is turned on after a suitable time delay and automatic speedsteering control resumed. Other figures (not shown), give details of the hydrostatic transmission.
