Patent GB-2292220-A (GB)
Title: Levelling aid
Inventor: YEO DENNIS GEORGE
IPC: G01C9/12
Filed: 1994-08-11
Abstract: The device comprises a first arm 1 linked to a second arm 2 about a pivot point 3. The second arm 2 carries a plumb weight 4 at one end and has a point 5 at the other end which can register with markings on a circular portion 6 of the first arm 1 as the two arms rotate relative to one another. In use, arm 1 is held against a wall so that the arm 2 hangs freely under gravity. The first arm 1 can then be rotated on the wall surface until the point 5 registers with one of the markings on the circular portion 6 so that, for example, a straight edge 7 on the arm 1 defines a horizontal line. This straight edge 7 is provided with ruler markings 8. If desired the arm 1 can then be rotated through 180 DEG  (about a locating point 9 of the pivot 3 which presses into the wall surface) so that an extension of the line drawn can be created on the symmetrically positioned straight edge 10. A described alternative (Figs. 3, 4) includes a rule with a slot and a scale to either side of the slot. A slide runs in the slot. At one end of the rule a vertical reference dial comprises a scale and plumb needle. <IMAGE>

Abstract: 946,454. Control of A.C. motors; retractive switches. E. J. SCHAEFER. Feb. 11, 1960, [Feb. 27, 1959], No. 4840/60. Headings H2B and H2J. [Also in Division F2] A clutch engaged to connect the shaft of a reversible electric motor to a driven shaft is controlled electrically by a hand-operated switch in a circuit also controlling the operation and direction of drive of the motor, the clutchengaging device and the switch being operated simultaneously. As shown, a circuit for the conjoint control of a reversible electric motor 25, Fig. 11, having field windings 131, 132, and of three positive clutches (see Division F2) in a hospital bed control mechanism, the clutches being selectively engaged by energization of three solenoids 79, comprises three hand-operated throw-over switches 138 closed one at a time and a similar reversing switch 144 always closed when a switch 138 is closed. The reversing switch 144 shorts a centrifugal switch 136, opened when the motor is driving, for instant reversal of the direction of motor drive, and is in series with a two-position switch 143 which senses the direction of motor drive. When the switch 144 is actuated to reverse the motor, current is immediately supplied through the switch 143 to the appropriate field winding 131, 132. Limit switches 118 are opened after a predetermined number of revolutions of an engaged clutch to disengage that clutch and switch off the motor 25. The manually operated switches 138 are mounted in a switchbox 26, Fig. 8, together with the reversing switch 144. The switches 138 each comprise fixed contacts 147, 148, Fig. 9, with a movable contact 154 therebetween of greater length, an axially slidable and rockable block 156 having ears 158, Fig. 8, selectively engaged with the extending ends of the movable contacts 154. The switch 144, of similar construction, has a central, movable contact at all times engaged with a lug 159, Fig. 9, on the control block 156. The control block 156 is fast upon a pin 157 held in three axial positions by a spring-biased bale detent 169 and biased by a leaf spring 172 to turn always to the central position shown in Fig. 9, when the movable contacts 154 of the switches are in their open positions. The pin 157 is fast with a Bowden cable 182 connected to a handle 181, Fig. 10, which can be mounted in a convenient position adjacent to the patient in the hospital bed. By axial movement of the handle 181, the pin 157 is slidden along to a position where the control block 156 is adjacent to one or other of the switches 138, so that the patient can select which of the shafts 22 ... 24 is to be actuated, for foot raising or head raising of the bed, &c., and then by turning the handle 181 in one direction or the other, can actuate the switch 144 to energize the driving electric motor 25 for rotation in one direction or the other according as to whether the bed head &c. is to be raised or lowered. The switchbox 26 is mounted in a position inaccessible to the patient and is provided with two override switches 146 which can be opened so as to prevent inadvertent actuation of the bed actuating mechanism.

Title: Method of Establishing a Direct Communication Path between Mobile Stations in a Cordless Telephone System
Inventor: LEE YONG-HO
IPC: H04B1/7156
Filed: 1996-03-29
Abstract: If a transmitter mobile station is within range of a base station, it detects sub-bands to check the presence of an available band and transmits a synchronization packet using an initial synchronizing frequency for direct communication if such an available band exists. If it is out of range, it selects a hopping pattern to cover the whole band and transmits the synchronization packet using the said initial synchronizing frequency. If a receiver mobile station is out of range of the base station, it detects the initial frequency for network communication and direct communication. Whether within or out of range of the base station, the receiver mobile station receives the synchronization packet, identifies the hopping frequency if appropriate and transmits a synchronization identifying packet in response. The transmitter mobile station receives the synchronization identifying packet and establishes a communication path with the receiver mobile station using the hopping pattern.

Title: Device for forming groups of articles in conveyor systems
Inventor: FRANCIONI RENZO
IPC: B65G47/08
Filed: 1997-07-02
Abstract: Groups, separated by periodic spaces and each containing n articles gathered together, are formed from a regular flow of articles (P). This result is achieved by means of a thrust element (11) which brings about the desired accumulation as a result of a forward acceleration performed on articles (P) in the direction of advance of the articles (P) once the articles (P) have been released from entrainment elements (9) on the conveyor (7). The acceleration is brought about by a drive unit (10) which drives the thrust element (11) constituted by a fork-like element. The fork-like element can perform a periodic rising movement unit it penetrates the flow of articles (P) followed by an active forward stroke of the element (11) causing movement of the articles (P) downstream until a group of articles has been gathered together. The preferred application is for automatic packaging of plants.
