Title: Improvements in or relating to canopies for vehicle windows and the like
IPC: B60J3/00
Filed: 1929-08-31
Abstract: 328,891. Magid, H. M. Aug. 31, 1929. Anti-dazzle screens.-An adjustable shield or visor designed for readv attachment to or detachment from vehicle windscreens or windows of various widths comprises a holder adapted to be secured frictionally to and to extend across the frame of the window &c., the side members of the holder being provided with inwardly facing grooves or channels, the ends of which nearer to the window &c. frame are open so that a sheet or shield of suitable dimensions mav be slid into place in the channels. In the construction shown in Fig. 2 (left hand side) and Fig. 5, the channels to receive the shield 11 are formed in a pair of brackets 12, one of which is mounted at each side of the vehicle by the engagement of an integral wedge-shaped projection 14 with the upper end of the groove 15 of the frame 16 for a sliding window. The brackets are combined integrally with transverse telescopic rods 17, 19 associated with an operating-nut 18, whereby the two brackets 12 may be forced apart to engage the projections 14 with the grooves 15 and thus mount the shield at any desired height and inclination. The sheet 11 is preferably made of corrugated flexible material which may be readily cut to the required size suitable to the width apart of the brackets 12. In a modification, Fig. 2 (right hand side) and Fig. 6, the channel members 20 are provided with rubber or like pads 21 for gripping the inside edges of the frame 22 and also with laterally and upwardly extending flanges 24, which are adapted to engage between a groove in the frame and a rubber or like lining 25 receiving the glass 26. In another modification the channel members are furnished with hook-shaped projections arranged to embrace the outer edges of a wind-screen frame and to grip the same when the operating- nut 18 is rotated so as to draw the channel members towards each other.

Title: Automatic load-dependent y-delta change-over system for electric induction motors
IPC: H02P1/32
Filed: 1954-09-14
Abstract: 754,066. Control of A.C. motors. LICENCIA TALALMANYOKAT ERTEKESITO VALLALAT. Sept. 14, 1954 [Sept. 15, 1953], No. 26685/54. Class 38(3) An induction motor M is changed to the delta or star-connection when the load is increasing or decreasing by means of a change-over switch 2 which is actuated by a relay 4 of the watt-metric type. As shown, the single winding of the control relay is energized both in accordance with a phase current of the motor and in response to the voltage between two phases of the supply, the resultant energization being proportional to the wattful current of the motor. The relay 4 is of the time-delay type, and its armature may have an extension carrying adjustable abutments for effecting the switching operations of the relay, the arrangement being such that the change from star to delta-connection is made at a higher current-value than the change from delta to star. In addition, the relay 4 may be provided with a dash-pot. A two-pole switch 5 disables the relay 4 and enables the motor to be operated permanently in delta.

Title: Storage batteries
IPC: H01M50/489
Filed: 1973-06-05
Abstract: 1415958 Storage batteries YUASA BATTERY CO Ltd 5 June 1973 [12 July 1972] 26859/73 Heading H1B A microporous sheet material may be made by adding ethanol to a THF solution of P.V.C., depositing the mixture on a non-woven fabric of polyester or polypropylene, and drying out. The material may be used alone, or heat sealed or otherwise adhered to an acrylic or styrenic bound glass mat or to a porous synthetic resin plate or a non-woven fabric, or used with a synthetic resin net. The material is folded over a plate of a lead acid battery and heat-sealed along one or more edges to form an envelope separator largely impervious to antimony. The backing materials may be chosen to space the separator from the plate to allow escape of gas or the microporous sheet material may have integral ribbing for this purpose. Slits are provided in the material before or after application to the plate to allow displaced active material to drop out of the bottom of the separator-the material is left intact in the region of the plate legs. The apparatus shown forms the envelope separators about the plates 3. Separator sheet 8 is drawn from supply roller 14 by a claw 16 and during a stationary interval is formed with slits by blade 17. When the sheet has moved on, plate 3 is pushed into the separator from a carriage 18 while the sheet end is held by claw 16<SP>1</SP>. The sheet is cut by blades 20 and the enveloped plate drawn between conveyers 22, 23 which are halted to allow use of the heatsealing tool 24 before being retracted to eject the enveloped plate on to a carriage 25 where a suitable plate stack (e.g. of plates alternately of opposite polarity) is built up. Claw 16<SP>1</SP> reaches up for the free end of the sheet material 8 to continue the process.

As described this frequency is half the clock rate and the clock rate is produced by a phase locked loop system comprising oscillator 28, frequency dividers 30, 32, 36 and phase comparator 44. The frequency of the generator 24 is adjusted to a frequency appropriate to the received data rate by a selector 26 which also controls as switch 34 which connects appropriate dividers between the oscillator 28 and the phase comparator 44 to bring the signal E12 to half the clock frequency. A further frequency divider 38 is also provided so that the system provides outputs at the clock frequency, half the clock frequency, and one quarter the clock frequency. Details of the circuits of the various units are given, Figs. 2-7 (not shown).

Abstract: 1,236,094. Chromatographic columns. ABCOR Inc. 6 June, 1968 [7 June, 1967], No. 26985/68. Headings B1L and B1X. The uniformity of flow of fluid sample streams in gas or liquid chromatographic columns is improved by dividing the stationary phase in the column by means of at least one partition element having one or more flow passages for the fluid stream therein, and having ridges or grooves on the face on which the stream impinges. As shown in Fig. 3, a and c represent elements with a central fluid passageway and with radial and helical ridges respectively. Such elements with only one passageway are used in combination with distributing elements such as sintered plates. Elements b, d, e and h have a plurality of passageways, the ridges in b and d extending radially from the passageways themselves, while in e the ridges form a grid and in h extend radially from the centre of the element. Elements f and g are of sintered metal with ridges of grid and radial configuration respectively. In Fig. 4a (not shown), an annular element (46) of triangular cross-section, apex towards the centre, is employed between two elements as illustrated in Fig. 3b. Reference has been directed by the Comptroller to Specification 1,075,920.

Abstract: 151,622. Bobst et fils, Soc. Anon., J. March 29, 1919, [Convention date]. Closing envelopes.-A machine for closing sachets or envelopes comprises a pair of coacting endless bands 3, 13 adapted to convey the envelopes 10 in an inclined position along a supporting-bar 22 and successively to a pair of creasing- disks 27, 27', Fig. 5, which form a crease to facilitate folding down the closing-flap of the envelopes, a curved bar which folds over the flap 11 to the position shown in Fig. 7 so that it can be glued by a roller 38, a second curved bar which completely folds down the flap, a pair of rollers 48, Fig. 10, which press down the glued flap, and to a shoot 54, Fig. 11, leading to a stacking-box 55. The bearing 30 of the shaft 28<1> of the creasing-disk 27<1> is pivoted to the fixed bearing 31 of the co-acting disk, a spring 32 tending to press the disks together. The shaft 28 of the disk 27 is rotated by bevel-gearing from the driving-shaft 8, and the shaft 28<1> is rotated by :gearing 29. The flap-closing rollers 48 are mounted similarly to the creasing-disks. An adjustable roller 45, Fig. 7, presses the flaps on to the glueing-roller, which dips into a tank 35 heated by a burner 36. As the closed envelopes fall into the box 55 they are stacked by a pusher 64 reciprocated by a lever 61 and a cam 58. Spring blades 77 carry at their free ends serrated checks which prevent return movement of the closed envelopes. An escapement finger 57 is operated by a projection 71 on the pusher 64 to time the fall of the envelopes.
