Title: Frame for a garden umbrella
IPC: A45B17/00
Filed: 1971-10-14
Abstract: 1357870 Garden umbrellas BREMSHEY A G 14 Oct 1971 31822/73 Divided out of 1357014 Heading A4P A garden umbrella is operable by operating a remote control lever 23', Fig. 3, to draw a carrier 12, carrying a crown 11, telescopically into a shaft 2 until the movement is limited by a stop 38, the displacement of the crown carrier during opening and closing being substantially equal to the separation D in the axial direction of the shaft with the umbrella open of the pivot 13' of each spoke 9, 15 to the crown from the pivot 5' of the corresponding strut 4 to a member 39 fixed relative to the shaft 2, and the component z of the displacement in the axial direction of the shaft of the pivots 10 between the spokes and struts 4 during opening or closing being substantially half the distance y between corresponding pivots 10 and 13'. A hinge part 26' of a stirrup-shaped lever 23' is coupled by a flexible tension element 27 to carrier 12, the part 26' being displaced vertically during opening or closing by a distance greater than y but smaller than the length of each strut 4, and y does not exceed about a third of the total length of each spoke. Lever 23' moves through a dead-centre position during opening so that no mechanism is required to retain the umbrella open, and after passing back through the deadcentre position subsequent closure is effected automatically due to the weight of the outer part of the cover. The shaft 2 comprises sections 2', 2" pivoted together at 51 so that the upper section 2" carrying the cover support assembly can be arranged at an angle to section 2', a slidable sleeve 48 being used to maintain sections 2', 2" in alignment when required. The tension element 27 passes through guide channels in a base member 42, in sleeve 48, in member 39 and in stop 38. By use of a wire-in-sleeve type connection the guide channel in the sleeve 48 may be eliminated, Fig. 11 (not shown). Outer spoke parts 15 may be removably engaged in channels 63, Fig. 13, in inner parts 9 by cross-slitting inner ball-shaped ends 73 of parts 15, springs 64 urging the parts 15 into tip member 66 stitched through holes 68 to the cover 67, loops 69 or disengagable press-studs further securing the cover 67 to spoke parts 15.

Title: Error detection and correction in data transmission
IPC: H04L1/16
Filed: 1974-07-18
Abstract: 1448178 Data transmission; error correction STANDARD TELEPHONES & CABLES Ltd 18 July 1974 31844/74 Addition to 1428050 Heading H4P In an automatic retransmission error correction duplex data transmission system as disclosed in the parent Specification 1,428,050 in which blocks to be transmitted are numbered in a cyclic serial sequence, which numbers may or may not be transmitted, with parity bits included in each block for error detection, the sequence character is added modulo-2 to all or preselected groups of parity bits of all, or some of the blocks in order to indicate, at the receiving end, non-alignment of counters defining the sequence characters. Where mod-2 addition is performed on some only of the blocks, condition of non-alignment is distinguished from transmission error as disagreement is registered only to the some blocks. The some blocks may be every nth block and preferably n is odd, e.g. n=3 in a particular embodiment. Fig. 1 shows one embodiment of a modification which may be made to a transmitter as disclosed in the parent Specification 1,428,050. When a block awaiting transmission is one to be modified, gate G3 is enabled when a group of four parity bits is approaching exclusive-OR gate A1, in which a sequence number stored in register SR1 is added mod-2, and thence passing through gate G2 to line. At the receiver, Fig. 2, parity bits generated from the incoming stream in decoder D are added to received parity bits in mod-2 adder A3 and if correspondence is registered gate G7 is enabled allowing contents of register RDS to pass to a utilizing device. Parity bits corresponding to those in which a sequence number is added are similarly treated hence sequence counter SCR counts correctly received and accepted data blocks the result being placed in a shift register SR2. When these particular parity bits are about to leave decoder D, gate G6 is enabled thus the sequence number and parity bits are added mod-2 in A2 the reuslt being applied to A3 at the same time as the modified parity bits are received from the remote station. As transmission error alters parity, an error indication will be given and similarly if transmitting and receiving counters fall out of step, the modified parity bits presented to A3 differ: this also gives an error signal (which may be different) hence adding sequence numbers to some blocks enables distinguishment between the types of error.

Title: Improvements in or relating to money boxes or like containers
IPC: A45C1/12
Filed: 1933-11-15
Abstract: 407,649. Savings' boxes. CARDIA, G., 74, Piazza S. Benedetto, Cagliari, Italy. Nov. 15, 1933, No. 31909. Convention date, Nov. 15, 1932. [Class 18.] A savings' box for money, &c., which cannot be opened until it is full comprises at least one articulated element f adapted to be deflected when pushed against a fixed element, such as the last coin q, to disengage the means securing the cover of the box. The element f forms one limb of a bifurcated slide e which moves between a fixed guide g and a pivoted lever h, the latter being pressed inwards by the upper end of a latch l, pivoted in the cover of the box and acted on by a spring r. If the box is full, the last coin q constitutes a fixed obstacle which, when the slide e is pushed in, forces the element f and lever h outwards and so causes the latch l to turn on its pivot and disengage its lower, hooked end from a projection m on the upper edge of the box. The cover can then be turned about its opposite edge where hooks t on the cover engage recesses u on the box. Both limbs of the slide may be pivoted, and the elements t, u replaced by latching means l, m ; or an articulated parallelogram, &c. may replace the elements e, f. The hooks t may be formed like band springs. A coin is inserted through an aperture masked by a hood i, and it rests in a channel o until pushed by the slide down a curved shoot into the box proper, the lower end of the shoot being provided with a door which closes automatically under the action of a spring or gravity. The box is made of sheet metal, &c., and the cover may be applied to any face thereof.

Title: Improvements in or relating to receivers for centralised remote-control installations
IPC: H02J13/00
Filed: 1953-11-18
Abstract: 728,729. Snap-action switches. COMPAGNIE POUR LA FABRICATION DES COMPTEURS ET MATERIEL D'USINES A GAZ. Nov. 18, 1953 [Dec. 17, 1952], No. 31987/53. Class 38 (5) [Also in Group XXXVIII] In apparatus for signalling over power lines by means of pulsed AF signals wherein the first pulse causes a synchronous motor to complete one revolution and the position of the second pulse in this revolution selects the required control, the second pulse causes the energization of a solenoid which moves a switch-actuating lever axially along the motor shaft to engage momentarily one of a series of switches located round the shaft. As shown, Fig. 1, an AF impulse sent over power lines A, B energizes a tuned selector S to produce vibration of a blade 3 followed by rotation of a cam 4 to close contacts 5a, 5b. A synchronous motor 7 is thereby energized via contacts 6, 20 to drive a shaft 9 via gearing 8 whereupon a cam 10 closes the motor holding circuit at contacts 6, 21 for one complete revolution of shaft 9. This shaft also carries a movable, switch-actuating finger 22, Figs. 1 and 2, attached to a spring-loaded armature 11. Receipt of the second AF impulse while shaft 9 is rotating causes energization of a coil 23 via contacts 5a, 5b, whereupon armature 11 and iron sleeve 15 are attracted to fixed iron sleeve 12, and the finger 22 is brought into the plane of the operating levers of a series of switches 24, to operate a particular switch as determined by the interval between the two pulses. Switch construction (Fig. 3). Two deformable, resilient blades 30, 31 attached at one end to a pivot 35 and a fixed rod 34 respectively, carry a moving contact 32 at the common ends. Attached to the pivot 35 is a plate 36 carrying contact levers 25, 25<SP>1</SP>. As shown, contact 32 is touching a fixed contact 35. When contact lever 25' is operated by finger 22, the blades 30, 31 move to the chain line positions, and contact 32 moves to the open position against stop 37. Simultaneously, contact lever 25' moves out of the path of finger 22, and contact lever 25 moves into it, so that subsequent operation by finger 22 on contact lever 25 will cause the switch to revert to its previous condition with contacts 32, 33 making.

A substation with a loud-speaker 38 arranged to serve also as a microphone has two separate amplifiers for amplifying speech in the two directions of communication, the amplifier for the incoming speech having at least its last stage 30, 31 operating as a class B amplifier, and a voice-operated relay 37 normally energized to connect the loud-speaker/microphone 38 to the input of the outgoing speech amplifier 25; incoming speech signals cause a rise in the potential difference across a load impedance (Fig. 3, not shown) in the last stage of the incoming speech amplifier, cutting off a normally conducting transistor 61 so that relay 37 is released and connects loud-speaker 38 to the output of the incoming speech amplifier 28, 30, 31. A delay circuit comprising a capacitor 65 prevents re-operation of relay 37 between syllables of incoming speech. An auxiliary microphone 70 and attenuator 71 give weak signals, permitting break-in even during incoming speech. A manual break-in key may be provided, as well as a key to prevent the loud-speaker's being used as a microphone, thereby avoiding eavesdropping. Extra paging loud-speakers, which cannot be used as microphones, may be added, together with their own amplifier (Fig. 4, not shown). Specification 853,671 is referred to.
