Title: Traverse winding of strip
Inventor: SANNOHE TAKESHI
IPC: B65H54/02
Filed: 1990-10-02
Abstract: A narrow strip having a width W is wound on a bobbin at an angle theta  to the rotational axis of the bobbin and at a pitch P, while the bobbin and the strip are being relatively traversed over axial stroke S. Considering that, for the number n = 2S/P = the number of bobbin rotations per reciprocating traverse of the bobbin or strip, where A is the integral part and B is the decimal part of n, then the winding is carried out, in the case when P<2W/sin theta , while controlling at least any one of P, S, and (P - W/sin theta ) so that (1 - W/Psin theta ) < B < W/P sin  theta . Thus, a narrow strip can be soundly wound on a bobbin while avoiding any collapse or other disorder in winding or any damage of the strip by adjusting the value of B that depends upon the values of P and S. <IMAGE>

IPC: E04G21/32
Filed: 1991-04-29
Abstract: A safety guard-rail apparatus, primarily but not essentially for a building structure has particular application for the roofing of building structures.

Patent GB-2251325-A (GB)
Title: Circuit for controlling the output of a sense amplifier
Inventor: LEE JEONG-WOO
IPC: G11C11/407
Filed: 1991-06-07
Abstract: Outputs of sense amplifier 600 are delivered to data latch circuit 700 via pass transistors 650, 660 which are switched by control circuit 610 responsive to the outputs 601, 602 of the sense amplifier. Until the read operation is completed (ie when lines 601, 602 have substantially different voltage levels) sense amplifier output detector 670 causes control signal generator 680, which also receives an ATD signal at terminal 604, to generate a control signal allowing the pass transistors to open and enabling the sense amplifier. When however completion of the read operation is detected the state of the control signal is switched, regardless of the state of the ATD signal to inhibit the sense amplifier and block the pass transistors. This prevents noise on the I/O pad from affecting the sense amplifier and reduces power consumption in it. <IMAGE>

Title: Testing wire rope for cross section variations and other flaws
Inventor: VAN DER WALT NICOLAAS TJAART
IPC: G01N27/82
Filed: 1991-11-01
Abstract: A wire rope is tested for defects by magnetically saturating the rope at two locations (b, f) in one sense and at an intermediate location (d) in an opposite sense, and detecting the output of a magnetic flex sensor located at one of the three locations. A sensing coil 32 at any of those locations detects cross sectional area variations in the rope. Two sensing coils (38, 40; Fig. 14) positioned respectively between each pair of adjacent locations detect contact pattern variations in the rope. Broken wires are detected by two coils (54, 56; Fig. 18) located respectively on opposing sides of the intermediate location and spaced apart by a distance which equals the radius of the coils. The output signal of the coil or coils may be integrated. <IMAGE>

When the touch plate is touched, body capacitance shows the output capacitance of the oscillator, reducing its output, to zero. Capacitor CA discharges and the output of inverter 14 goes high switching triac 21 and load 20 on. The apparatus may be used on a hair dryer, curling tongs or electrically powered hair brush with the sensor plate on the handle thereof. <IMAGE>

Title: Device for moving long articles vertically in parallel
Inventor: MORI CHUZO
IPC: B26D1/20
Filed: 1993-06-16
Abstract: A device for allowing vertical movement of an elongate member, with respect to a base member, while maintaining its parallelism with the base member. An elongate member 9 has supports 10 attached to either end. These supports have edges which cooperate with the sloped ends (151, 152, 161, 162 figs. 1 & 2) of two actuation levers 15 and 16. If one end support is pushed down onto edge (162, fig. 1) then lever 16 moves in the direction of edge (161 fig. 1) which itself engages a slot (105, fig. 1) to pull its support 10 down. At the same time lever 15 is moved in the opposite direction under similar action (fig. 2). This combined action ensures that the bar 9 remains parallel to the base. Bar 9 is biased in a raised position by springs (12, figs. 1 & 2) acting on supports 10. The device may be employed in a paper cutting device (fig. 4) where a cutting means 8 is slidable along a vertically movable guide rail 9. <IMAGE>

Title: A remote target detection system
Inventor: BLOOMFIELD JOHN W
IPC: G01S15/42
Filed: 1993-11-23
Abstract: Ultrasonic energy is emitted within a detection envelope from a single transducer (36) and echoes of targets therein are received during scanning displacement of the transducer through a predetermined sweep angle from a zero position on a platform, against the centering bias of springs through which pulse signal current is conducted to and from the transducer. An electromagnetic scanner drive (56) imparts oscillatory motion to the transducer by magnetic generation of displacing forces varied in accordance with its loading, at the zero position of the transducer and at limit positions defined by stop means, detected by a position sensor to maintain a constant scanning sweep angle in timed relation to pulsing of the transducer through a transmit-receive circuit under preprogrammed computer control. Relatively abrupt changes in transducer motion may also be detected. <IMAGE>
