Filed: 1965-05-07
Abstract: 1,152,361. Stays for windows and doors. W. J. CAMPBELL. 4 Aug., 1966 [7 May, 1965], No. 19303/65. Heading E2F. A device for holding a hinged or pivoted window (or door) in different positions comprises an operating bar 1 carrying a guide 2 in which' the bar is slidable and first and' second brackets 3, 4 connected to one end of the bar 1 and to the guide 2 for attachment to the window frame and fixed frame respectively, the brackets being pivoted so as to permit opening and closing adjustment of the window by the bar, the bar and guide having faces or formations adapted to be brought into engagement upon axial rotational adjustment of the bar relative to the guide so as to lock the bar against sliding movement, and the bar being axially rotatably adjustable relative its end bracket and to the guide to effect locking and unlocking of the bar. As shown in Figures 1, 4 and 5, the bar 1 is elliptical in cross section and has a plurality of axially spaced zones 10, 11 of circular cross section of diameter equal to the minor diameter of the bar. The guide 2 has a circular bore 14 and an elliptical bore 13 forming a key. The ellipse of the bore 13 is slightly greater than the ellipse of the bar 1, so that the bar can slide in the guide 2 and, when a depression 12 is aligned with the key in the guide, axial rotation of the bar locks the bar in position. The bar and guide may be separable and the bracket 4 (Figs. 8 and 9, not shown) may be suitable for a window which pivots about a horizontal axis. In Fig. 10 (not shown), the guide is formed from two strips ofmetal 29 and 30; bent to a U-shape and fitted one within the other to provide a flange 29B and 30B and a passage corresponding to the bore 13 of Fig. 5.

Title: Implantable body tissue stimulating device having adjustable oper ating parameters
IPC: A61N1/372
Filed: 1972-04-26
Abstract: 1385954 Stimulators CORDIS CORP 26 April 1972 [10 May 1971] 19303/72 Heading A5B An implantable body tissue stimulator, such as a bladder phrenic nerve, carotid sinus or cardiac stimulator, comprises means for detecting pulse signals applied externally of the patient, a counter 43 interconnected with said detector for counting detected pulses, a stimulating pulse generator 11 having at least one adjustable pulse output parameter, and a decoder interconnected with the counter for controlling said parameter in dependence on the count held in the counter. A cardiac pacer has a pulse generator 11 comprising an output transistor Q3 driven by a relaxation oscillator Q1, Q2, the pulse repetition rate being controlled by resistor chain R4 to R8 and the output pulse current being adjustable by opening or closing a switch 17. A switching block 15 selectively shuts resistors R4 to R7 according to the state of counter 43 which also controls switch 17 to provide 16 pulse rates at each of two output currents. A magnetic read switch 21 senses external magnetic pulses and passes pulses to a pulse shaping one-shot multivibrator, comprising NOR gates 23, 25, which meshes bounce in switch 21. If the detector pulse rate is above a minimum determined by the time constant of R3, C2 an inverting gate 27 removes a reset signal from decade counter/decoder 31 which then counts the detected signals. After circuit 31 has counted six pulses it resets binary counter 43 and when circuit 31 reaches its seventh state it stops counting and counter 43 starts counting, the switches 15 and 17 staying in the state corresponding to the count in counter 43 when the external magnetic pulse brain stops.The count threshold of circuit 31 provides a high degree of noise immunity. Integrated circuit techniques may be used to form the components of the detector, counter and decoder as a plurality of integrated circuit clips or as one large clip. The binary counter 43 may be expanded to also control a pacer generator to operate in a synchronous or non- synchronous mode or in a standby or continuous mode. A semiconductor magnetic sensor may be used instead of switch 21, and instead of external magnetic pulses bursts of acoustic energy may be transmitted through body tissue or electromagnetic pulses, e.g. at 15-150 kH 2 , may be utilised. The control circuitry may also be used with a digitally tined cardiac pacer such as that described in Specification No. 1,267,493. Reference has been directed by the comptroller to Specification 1,331,967.

Title: Improvements in driving mechanism for sheet-feeding devices in duplicating and like machines
Inventor: FORD RONALD MAX
IPC: B41L39/06
Filed: 1950-08-04
Abstract: 719,052. Feeding sheets; rotary duplicators. FORD, Ltd., F. R., and-FORD, R. M. July 24, 1951 [Aug. 4, 1950], No. 19507/50. Classes 100 (1) and 100 (2). In a rotary duplicator having means for adjusting the starting time of the sheet-feed means relatively to the master cylinder, a roller 42 mounted adjustably on the end face of the master cylinder 11 is adapted to strike a face 41 on a toothed sector 37, pivoted at 38 on the machine frame, to oscillate the sector on every revolution of the cylinder. The sector drives a pinion 40 secured to a shaft 25, which drives a roller 20 through chain-and-sprocket and free-wheel gearing, as described in Specification 678,157. A feed roller 29, which may be a moistening roller, is driven by a pinion 48 meshing with a sector 49 also oscillated by the roller 42. The roller 20 feeds sheets from a pile 16 to the moistening roller 29 and co-operating roller 30, and these forward the sheet between the cylinder 11 and impression roller 36. The roller 42 is carried by a mounting 50, 51 which can be adjusted, about the shaft 56 of the cylinder 11, relatively to the clamped edge 13 of the master sheet, whereby the position of the leading edge of a sheet fed from the pile can be adjusted relatively to the master sheet. The mounting comprises two flat plates 50, 51, both pivoted about the shaft 56, joined together and held to the cylinder 11 by screws 53, 55 passing through slots in the plates. The plate 51 has an open-ended slot 57 fitting over a cam 58 mounted eccentrically on a shaft in the cylinder, and a notched drum secured to this shaft co-operates with a spring-pressed pawl whereby the cam can be adjusted. Rotation of the cam 58 thus adjusts the angular position of the mounting 50, 51 and the roller 42 relatively to the cylinder. A coarse adjustment of the roller 42 is effected by slackening the screw 55 and shifting' the plate 50 relatively to the plate 51.

Title: Improvements in and relating to light signals
IPC: G08B1/08
Filed: 1932-07-12
Abstract: 404,649. Lamp - failure alarms. BRITISH POWER'RAILWAY SIGNAL CO., Ltd., GLENN, S. L., and PIERCE, E. E., Windsor Works, Slough. July 12, 1932, No. 19720. [Class 118 (ii).] A lamp signal having a repeater relay or other device in series with the lamp has a dimming circuit comprising resistances arranged so that the current to the repeater relay or other device is substantially unaltered whether the lamp is on full or dim operation, so long as the lamp is intact. The dimming arrangement essentially comprises a series resistance causing a voltage drop to the lamp and a parallel resistance to allow a make-up current to flow. The Figure shows an arrangement for alternating current working. A manually, clock- or selenium-cellcontrolled relay 8 when energized lifts its contacts 9, 10 whereby the lamp 4 of a spectacle signal is dimmed by being connected in series with a resistance 12 over front contact 10 ; a shunt current flowing over front contact 9 and a resistance 13 brings the total current flowing through the local control winding 5 of the spectacle up to normal value. The resistances 12, 13 are provided by windings on a choke core 11 arranged in opposition and so giving no resultant flux. On failure of the lamp, when on dim working, the flux arising from winding 13 is no longer balanced so that this winding now has considerable impedance and the alternating current flowing through the local control winding 5 is thus reduced below the release value and causes the signal mechanism to move to the most restrictive signal aspect. On daylight full-power working the lamp 4 and local control winding 5 are in direct series over back contact 10 of the dimming relay 8. The choke impedance may be made resonant and the choke itself may actuate an indicator. An alternative arrangement suitable for direct or alternating current comprises, in place of the choke with opposing windings, independent resistances or impedances similarly arranged in shunt and series and as the reduction of current on lamp failure during dim operation would only be a fractional one since no inductive reaction is created by an unbalancing of the fluxes, this current is further reduced by inserting in series with the lamp a relay which on dropping its contacts opens a short-circuit shunt round a resistance in the feed line. Specification 404,653, [Group XI], is referred to.
