Patent GB-660642-A (GB)
Abstract: 660,642. Calculating-apparatus, mechanical. NATIONAL CASH REGISTER CO. May 6, 1949 [July 17, 1948], No. 705/50. Divided out of 660,620. Drawings to Specification. Class 106 (i). The subject-matter of this Specification is identical with a part of that described in Specification 660,620, but the claims are for a reset counter associated with a line of totalizers. These totalizers are reset in a succession of operations and only the first is registered by the counter. The counter actuating pawl is held inoperative after a first actuation by the reset key, and is not released until the machine has operated with the reset key undepressed.

Title: Photoelectric profile follower
IPC: G01B11/00
Filed: 1978-11-23
Abstract: A photoelectric device follows the profile of a template and generates an electric output signal representative of the profile for controlling a profile copying machine. Head 4 for engaging and following the profile to be copied is mounted on arm 2 pivotally displaceable with respect to a datum axis running through the device's axis of symmetry. Light reflector 11 is carried on and displaceable with the arm to deflect light beam 10 from a zero position on a photosensitive element 6 which generates an electric output signal representative of such displacement. Light beam 8 is directed parallel to the axis and is deflected and directed along the axis by fixed prism system 9, 13 through which the reflected light beam 12 passes to photosensitive element 6 which is disposed on the axis. Transparent plates 15, 16 are angularly adjustable about mutually perpendicular axes to initially centre the reflected beam on the zero position of the photosensitive element. Further photosensitive device 24 provides a measure of the intensity thereof and can be used to control the light source 7. <IMAGE>

Title: Rotary positive-displacement fluid-machines
IPC: F04C15/00
Filed: 1978-12-06
Abstract: A meshing screw pump is provided with idler screws (2, 3) and a drive screw (4) for pumping fluid from a suction chamber (6) to a pressure chamber (7). A scavenging fluid circulates through a passage (22), a compensating tank (23), a line (24) and a chamber (16). A thrust-balancing piston (11) is provided between the pressure chamber (7) and the chamber (16). The balance piston (11) is encircled by a throttle gap (13) and an annular chamber (14). The latter is connected by a line (15) to the suction chamber (6); and thus fluid from the pressure chamber (7) rising in the throttle gap (13), rather than entering the chamber (16), returns to the suction chamber (6) via the annular chamber (14) and line (15) and moreover, the fluid being pumped, which may be hot oil, does not contact a seal (17). <IMAGE>

Title: Frost and temperature control system
IPC: G05D23/19
Filed: 1979-01-18
Abstract: A control apparatus for use with heat pumps, especially refrigeration systems to maintain a desired ambient temperature within an environment and a frost-free condition on an evaporator coil of the system. The control apparatus Figure 3 includes ambient temperature sensing circuits 160, 180 responsive to the temperature of a refrigerated chamber and evaporator coil respectively. The circuits 160, 180 each produce a "1" output when the chamber temperature is above a desired level and the evaporator coil temperature is below melting point level respectively. A frost sensor 150, which may be capacitive, produces a "0" output when frost build-up is excessive. A logic circuit 130 responds to these outputs to control relays 118, 120 whereby the defrosting means 116 and heat transferring cooling means 114 cannot be in an activated state at the same time. <IMAGE>

Title: Rolling Cutter Drill Bit
IPC: E21B10/22
Filed: 1979-01-26
Abstract: The present invention provides a rolling cutter bit having a plurality of rolling cutters 30 each rotatably mounted on a lug member 12 having a downwardly extending bearing journal 18. Each bearing journal 18 has a ball bearing race 22 formed therein for receiving a series of ball bearings 28 which also seat in a mating ball bearing race 32 formed in the rotatably mounted cutter 30. The ball bearings 28 are arranged to share the axial loading placed on the rolling cutter 30 and primarily lock the cutter 30 on the journal shaft 18. Each journal 18 is further provided with a unique large thrust surface 24 across the downward end of the bearing shaft 18 and generally perpendicular to the radial bearing surface 20. The large flat perpendicular thrust surface 24 eliminates the need for a standard pilot pin structure normally found in known rolling cutter bits. <IMAGE>

Title: Apparatus for the production of ozone
IPC: C01B13/11
Filed: 1979-02-12
Abstract: Apparatus for the production of ozone comprises a housing divided by partitions into a discharge chamber E and gas supply and gas removal chambers GZ and GA, which chambers communicate by apertures through the partitions (which in the embodiment shown also form two electrodes H1, H2, between which high voltage is applied by generator G), and a pump P for passing a gas to be treated through the discharge chamber. As a result of the arrangement of electrode partitions and the gas flows caused thereby, a thin boundary layer exists between the discharge arc and the surrounding gas, which provides more rapid cooling of the ozone than hitherto and therefore a higher ozone yield. <IMAGE>

Title: Clamping Cutting Tool Inserts
IPC: B23C5/22
Filed: 1979-08-24
Abstract: A holder or nest 30 for pin-type replaceable cutting inserts 15 having a circular aperture 16 centrally disposed therein, includes a pin 50 extending perpendicularly to the face of the holder, the pin being formed with a pair of opposed axially- extending portions 50, each of which comprise a segment of a circular cylinder having a periphery less than 180 DEG .
