Title: Conveyor cut-off gate
IPC: G01G13/16
Filed: 1978-08-01
Abstract: A cut-off gate for controlling flow of a loose product, such as potato chips, comprises a blade member 36 located between the discharge end of a conveyor 14 and weighing hopper 20. The blade is mounted on a reciprocating carriage 38 for movement to control flow of the product from the conveyor to the hopper in response to signals generated by the weighing scale. The gate effectively catches the product in flight, thereby reducing give-away. During each cycle, a wiper 70 maintained in abutment with the blade member removes any build up of product from the gate, and seals around the feeding conveyor to prevent product spillage. An air jet 74 discharges each weighted charge of the product through a gate hopper outlet 30 for packaging. <IMAGE>

Title: Improvements relating to incontinence pads
IPC: A61F13/15
Filed: 1979-03-28
Abstract: An incontinence pad has a permeable membrane (8) covering an absorbent filling. The membrane is perforated in such a way that it has a one-way property, allowing liquid easy access to the filling, but severely restricting reverse flow. The membrane, of plastics sheet (1), is laid on an apertured base and punctured by blunt angled blades (4), which stretch the plastics material into the apertures (3) before penetrating. This leaves flaps (5,6) which form one-way valves at each aperture (7) in the sheet. <IMAGE>

Patent GB-2026617-A (GB)
Title: Storage and Adjustment of Hydraulic Pressure
IPC: F15B1/08
Filed: 1979-07-27
Abstract: Hydraulic operating fluid and compressed gas are contained in a storage vessel 1. The pressure of the gas acts on the hydraulic fluid to drive the fluid to an external device operated thereby. The apparatus makes it possible to alter the gas pressure. A second vessel 14 contains a gas volume communicating with the gas in vessel 1, and a fluid. The fluid quantity in vessel 14 can be increased by pump 24 pumping in more fluid from reservoir 25, or reduced by exhausting fluid via valve 26 and duct 27. The fluid can never be completely drained from vessel 14, and thus a fixed gas volume is trapped in the two vessels, and the pressure of this gas will be increased by pumping more fluid into vessel 14, or reduced by exhausting fluid. <IMAGE>

Filed: 1979-08-31
Abstract: The storage life of isophorone, as measured by the time taken to develop an acidity of >/=0.0% w/w as acetic acid and/or a colour of >/=60 Hazen units is extended by the addition of antioxidants of the type polyhydroxybenzene or alkyl substituted mono- or polyhydroxybenzene, or derivatives thereof. The preferred antioxidant is 2,6-di-tert-butyl-4-methyl phenol (BHT) in an amount in the range 50 to 1000 ppm. Further improvement can be achieved by storing the isophorone/antioxidant composition in the dark or in an oxygen-free atmosphere.

Patent GB-2041545-A (GB)
Title: Constant voltage insulation resistance tester
IPC: G01R27/02
Filed: 1979-11-07
Abstract: Sufficient voltage Vx for measuring insulation resistance Rx, even when Rx is small and current Ix is large, is obtained from a rectifier circuit D1, D2 for boosting and rectifying the output of a battery-supplied oscillator OSC receiving a voltage feedback to vary its mark-space ratio, depending on voltages Ef and Ez1, such that the voltage drop across R4 due to Ix does not exceed a predetermined value. Alternatively, when this voltage drop exceeds this predetermined value, diode D3 conducts and there is simultaneous voltage feedback and current feedback. Thus, a short-circuit between E and L causes Vx to drop automatically to prevent power loss by an increase in Ix. A moving coil meter M receives current IM bearing a non-linear relationship with Ix due to three series circuits each including a semiconductor switch D4, Q or D5 and resistor R11, R13 or R15 which sequentially start to operate as Ix rises, providing a polygonal approximation to a logarithmic response. Switches S1 and S2 enable the unwanted presence of an external high voltage to be detected and continuity of the test conductor to be verified through buzzer Bz. <IMAGE>

Title: Multi-step mesa
IPC: H01L21/308
Filed: 1980-02-19
Abstract: Multi-step mesa walls are formed by pretreating one or more selected portions 262, 252 of the semiconductor material which is to be removed by etching to form the mesa to change the average removal rate of the pretreated material in the subsequent etching step; protecting by a mask 245 portions 244 etc. of the semiconductor material's surface while leaving unprotected those portions, including non-pretreated portions 272, of the surface which are to be removed to form the plateaus of the mesa wall; and exposing the semiconductor wafer to a single etching process which removes the pretreated material at different rates than it removes the non-pretreated material. Thus single etch and single masking steps may give plural depths of etch. The pre-treatment may be a doping step (N+) which is used to simultaneously provide contact areas elsewhere on the chip. <IMAGE>
