Title: Method and apparatus for applying strips of material to a web
Inventor: OSHEFSKY DANIEL JAMES
IPC: B65H20/00
Filed: 1985-11-19
Abstract: A method and an apparatus in which continuous strips (16, 18) of a first material, e.g., elastic strips, are continuously supplied to flexible strip supports (32) in a supply zone (S) while the strip supports (32) are in a linear configuration. The strip support (32) are carried on respective transfer members (30) which are mounted on a rotatable support (34) so that individual transfer members (30) follow a closed (orbital) path upon rotation of the support (34). The continuous strips (16, 18) are cut into discrete strips adhered to respective flexible strip supports (32) whose configuration, and that of the discrete strips (16, 18) adhered thereto, is then changed to a desired curvilinear configuration. The transfer members (30) are then brought into transfer contact in a transfer zone (T) with a moving web (24a) of second material, which may comprise the backing sheet of a disposable diaper construction, and the curvilinear strips (16, 18) are transferred to the web (24a). Alternatively, or in addition, the individual transfer members (30) are supported on radially translatable supports (48) so that during rotation the orbital radius and thereby the linear velocity of individual transfer members (30) may be selectively varied between a first radius and consequent linear velocity in the supply zone (S) and a second radius and consequent linear velocity in the transfer zone (T). The individual transfer members (30) may also be pivoted to selectively orient the strips (16, 18) relative to the moving web (24a) in the transfer zone (T).

Title: Improvements in fishing rod rests
Inventor: PERCY MICHAEL GEORGE ERNEST
IPC: A01K97/10
Filed: 1986-01-20
Abstract: A rest for a fishing rod comprises an elongate tubular member (1) having a pointed member (2) at one end for planting the rest in the ground and a pair of arms (3, 4) at its other end for supporting a fishing rod. A fixed electrical contact (5) is secured by screws (7) to one arm (3) and a movable electrical contact (6) is secured by a screw (8) to the other arm (4), the movable contact (6) being urged into engagement with the fixed contact (5) by a spring (9). The contacts (5, 6) are connected by electric wires (15, 16) to a buzzer (17) and a dry cell (14) located in a casing (11) which is secured to the tubular member (1). When a fishing rod is laid between the arms (3, 4), it depresses the movement contact (6) so that contact with the fixed contact (5) is broken. If the rod is removed, the movable contact (6) will again be urged by the spring (9) into engagement with the fixed contact (5) to close the electric circuit and activate the buzzer (17). This will alert the owner of the fishing rod to unauthorised removal of the fishing rod from the rest and prevent theft of the rod. <IMAGE>

Patent GB-2181578-A (GB)
Title: Clock delay for microprocessor
Inventor: BIZJAK KARL MICHAEL
IPC: G06F1/08
Filed: 1986-06-04
Abstract: The present invention is for increasing the performance of a microprocessor CPU coupled on a bus to a plurality of data processing devices. The invention includes a finite state machine coupled between a clock generator and the CPU for generating the CPU clock and extending predetermined clock cycles (as at 4) for a predetermined fraction of a cycle. Logical operations in the CPU are held in await condition for the time the clock signal is extended. The induced delay of the predetermined clock signals occurs only during operations involving signal transmissions between a data processing device and the CPU over the bus. For internal CPU operations not involving bus access, the CPU is driven at its maximum permitted rate. Accordingly, the performance of the CPU is increased since the CPU need not be maintained for complete CPU clock cycles in a waiting state until the slower data processing device which it is accessing over the bus completes operation. <IMAGE>

Patent GB-2195843-A (GB)
Title: Energy transformation apparatus
Inventor: MORRIS NEIL
IPC: H05B41/392
Filed: 1986-09-29
Abstract: Apparatus for transforming electrical energy into another non-heat, non-kinetic energy form, comprises a high Q resonant circuit loop containing a static energy transformation device in the form of a chemical cell or a discharge lamp and a pulse generator for generating electrical pulses at a repetition rate corresponding to the fundamental resonant frequency of said loop. In a circuit for reactivating primary cells or recharging secondary cells, an integrated circuit timer 11 drives the resonant loop 18 via a transformer 17 the secondary winding of which forms the inductive elements of the loop. When a diode 19 is forward biased, the inherent capacitance of the cell 21 is the predominant capacitance of the loop 18 and determines the fundamental resonant frequency, whereas the capacitance of the diode 19 predominates, when it is reverse biased and the circuit 18 rings with a damped oscillation at a higher frequency. Adjustable elements 12, 13, 15 allow the frequency, mark/space ratio, and amplitude of the energising pulses to be altered. In an alternative charger, the transformer forms part of a blocking oscillator (Fig. 3). A discharge lamps drive circuit (Fig. 4) may also use a blocking oscillator, the resonant loop capacitance being determined by the capacitance of the lamp (61) before a plasma forms therein. The oscillator may receive a D.C. supply from an A.C. to D.C. converter having a phase controlled triac (42) for adjustment of the supply voltage. <IMAGE>

Patent GB-2183290-A (GB)
Title: Device for controlling the movement of a door
Inventor: EVANS DAVID HOWARD
IPC: E05F3/22
Filed: 1986-11-17
Abstract: The device, particularly for controlling the closing movement of a door (11, Fig. 6), comprises a linkage mechanism (45, 46, 47, 51) connected between the frame (10) and a door closer device (15) mounted on a backplate (13). Backplate-mounted means to retain the door open has a spring-biased arm (34, Fig. 2) movable downwards against spring (42) bias until a linkage part (51) on a catchplate (47) passes over, whereupon the arm rises so that a surface (38, Figs. 2 and 6) of the arm holds the linkage and door open. In manually shutting the door, the arm (34) is thrust down by the linkage part (51) so that the closer operates. To automatically shut the door, where fire is detected, an electromagnet is released to allow an arm (19) to pivot under spring bias and thus allow the spring-biased arm (34) to move axially and release the door. If the catch plate (47, Fig. 6) is free of the main arm (45) the door is free-swinging once it is moved to an open position. Accordingly simple fixing means (49, 50) are used so that conversion from a free-swinging door to a held open door or vice versa can easily be carried out. In the event of a fire however, the door is automatically closed by the released catchplate, regardless of whether it is in a free-swinging or held open state. <IMAGE>
