Title: Interrupted zip lock closure providing pressure relief for microwaveable reusable pouches or sachets
Inventor: OLSON CARL
IPC: A44B19/10
Filed: 2008-03-25
Abstract: An interrupted zip lock reclosure facility for reusable microwaveable flexible pouches or sachets to enable the venting of pressure during microwave cooking. The interruptions may be created by not welding the zip lock to the body of the pouch or sachet at one or more points along its length or they may be created by physical gaps in the zip lock at one or more points along its length. The interruptions allow sufficient steam pressure to escape from the pouch or sachet during the cooking process to ensure the zip lock does not burst open while preferably still retaining sufficient steam pressure inside the pouch or sachet to enable significant steam cooking of the contents and also providing anti-splash and accidental spillage protection.

Filed: 2009-02-09
Abstract: A power supply and control apparatus for an environmental conditioning system comprises a relay R1, a semiconductor switch Q1, an AC load and a DC load, where the relay and semiconductor switch are arranged in series between an AC mains supply and the AC load, and where the DC load is control electronics including a plurality of capacitors C1. The capacitors are arranged such that one of the capacitors continues to supply stored energy even if another capacitor fails. The capacitors are charged using the load current and the stored energy used to run the control electronics. As the charge is used the capacitor is recharged as and when required. The MOSFET Q1 is used as a switch, forcing the load current to charge the capacitors, power stealing (fig. 1(a)), and then to bypass the capacitors and supply the AC load (fig. 1(b)). The AC load is an environmental conditioning load and may be at least one of a lighting load, a heating load and an air conditioning load. The control electronics may be arranged to detect shorting of one or more of the capacitors and operate the relay accordingly, or to sense the load current and operate the relay if it exceeds a predetermined threshold.

Abstract: 745,924. Hydraulic machines. ATELIERS, G.S.P. GUILLEMIN SERGOT PEGARD. April 13, 1953 [Dec. 31, 1952], No. 10002/53. Class 69 (2). A hydraulic control device for imparting intermittent displacements to a movable member comprises a transmitter M comprising a cylinder-block 3 having a single-acting piston 4 operated by a cam 6 and returned by a spring 5, and connected to a receiver unit consisting of a cylinder having a piston 22 integral with a rack 32 meshing with a pinion 33 integral with the outer component 34 of a free-wheel, the inner component being integral with a bevel pinion 35 transmitting movement to a shaft 42 through a sliding reversing clutch 41. The shaft 42 threadedly engages a table T. The stroke of the piston 22 is limited by means of an adjustable stop 25. Liquid displaced by the piston 4 after the piston 22 has stopped acts on a differential piston 13-14 which forces a by-pass valve 11 to open. The valve 11 is closed at the commencement of a cycle by a cam 9. The transmitter may be by-passed by a hand-controlled valve 16. In a modification a second piston-rack engages the receiver pinion and towards the end of the receiver piston stroke the second piston-rack enters a cylinder displacing liquid through a tapered slot in the piston to damp the movement. The return stroke of the receiver piston is limited by an adjustable stop with which the second piston-rack engages. The valves of the transmitter unit are replaced by a spring-pressed ball relief valve and a handcontrolled by-pass ball valve.

Title: Improvements in or relating to radio receiving sets
IPC: G04C23/00
Filed: 1937-04-08
Abstract: 487,977. Electric control systems. STEVENS, A. H. (Smiley, J. B.) April 8, 1937, No. 10034. [Class 40 (i)] The invention relates to a method of tuning a receiver to predetermined stations at and for predetermined times. The operating spindle 12 of the tuning element of the receiver is connected through a clutch assembly A to a shaft 33 which is rotated or oscillated by the rack-and-pinion 35, 36, operated through gearing and a pin-and-slot mechanism 32 by an electric motor 23, energized from the supply mains Z through switch contacts 52 operated by solenoid 70 in control circuit D ; contacts 74 are simultaneously operated to open the loudspeaker circuit during tuning by the selective control device. The circuit D, which controls the operation of motor 23, includes a timing device 21 comprising an electric clock, the hour hand 65 of which carries a flexible contact 66 engaging a number of contacts on an insulating ring 59 at the clock-face periphery. These contacts are 48 in number to cover each 15-minute interval over 12 hours and each contact is connected over leads 63 to a corresponding jack on a panel 58 ; the jacks 71 are arranged in 12 vertical rows of four, one row for each hour, each horizontal row representing the quarterhours. The station selector device comprises a conducting disc 80 rotating with the shaft 33 and having a flush insulating radial segment 81. A stationary disc 82, associated with disc 80, has a number of spring-loaded contact balls arranged round 180‹ of its periphery in a band corresponding in depth to the length of the strip 81 and making contact with disc 80. The number of these balls corresponds to the number of scale divisions on the receiver condenser tuning scale and each ball is separately connected over lead 88 to one of a series of jacks 89. Connections between the jacks 89 and jacks 71 is effected by plug conductors ; thus, if a station, tuned in at numeral 71 on the tuning scale, is required to be heard at 7.30 p.m. one plug of the conductor is inserted into jack 71 and the other plug in the third jack of row 7. The control circuit D, supplied from the secondary of transformer 69, is then energized at 7.30 p.m. at contact 66, solenoid 70 closes contact 52 and motor 23 rotates shafts 12 and 33 until the spring ball on disc 82 connected to jack 71 reaches the insulating segment 81 ; control circuit D is then broken and the receiver continues to work on the station so selected until circuit D is again completed. Jacks may be multipled as at 95 to provide for one station being tuned in several times during the 12-hour period. Remote control may be effected by switch 107 in parallel with switch 52. The control circuit D may be switched on or off by a switch 102 operated by the push-pull rod 44 which engages or disengages the clutch 37, and the set may be switched on or off by the solenoid-operated arm 111 actuated on plugging into the ON or OFF jacks in panel 58.
