Title: Improvements in or relating to multi-channel carrier telecommunication systems
IPC: H04M3/32
Filed: 1956-02-06
Abstract: 821,842. Two-way transmission. SIEMENS & HALSKE A.G. Feb. 6, 1956 [Feb. 5, 1955], No. 3631/56. Class 40 (4). In a multichannel carrier system in which the channels are arranged in a number of groups, to each of which a pilot is allocated, failure of a pilot frequency results in the channels of the associated group being marked engaged provided that the fault does not affect only the channel over which that pulse frequency is transmitted, or is not in the equipment provided for the reception of the pilot frequency. Failure to receive the pilot signal in pilot receiver PE5 causes a marking device SP-UE3 to send a pulse to terminating unit TF-UE1 and over one of the channels of group KG1 to the; terminating unit TF-UE6 and marking device SP-UE8 at the distant end. Reception of the pulse in the marking device initiates a similar return testing pulse through group KG4-KG2 to the marking device SP-UE3, the reception of which indicates that only the pilot channel is faulty and prevents the channels of the group being marked engaged by the terminating unit. When the channels are marked engaged by the device SP-UE3 the pilot transmitter PS4 is suppressed to cause the other ends also to be marked. The marking may be cancelled automatically when a faulty pilot is restored. The return marking may alternatively be transmitted by a change of pilot level which may be periodic, and in the latter case, marking relays are arranged to distinguish between a periodic change and a protracted change. Periodic keying of the carrier for such return signalling is prevented from affecting automatic gain control apparatus. Duplicate pilot supply equipment is preferred and arrangements for testing the pilot receiver in the event of pilot failure comprise applying a locally generated current of approximately pilot frequency which may be a harmonic of mains frequency or generated by feedback in the receiver when the pilot fails. A two pilot system may be marked faulty only when both have failed.

Title: Improvements in and relating to door-closing and -checking devices and the like
IPC: E05F3/16
Filed: 1924-02-12
Abstract: 220,564. Smith, H. Feb. 12, 1924. Operating and controlling doors by springs and checks. - A door provided with a closing spring is checked by a brake device that comprises a brake shoe adapted to be drawn into frictional engagement with the brake surface by a wedge-like action as the door closes. In the arrangement shown, a drum 3 connected to the operating lever 1 has a brake surface 3a that is engaged by a spring- pressed shoe 8 to form the door check. During the opening movement of the door against the action of the closing spring the surface 3<a> slides over the wedge, which tends to be displaced against the action of the spring 6<a>. As the door closes, this spring forces the wedge between the abutment 9 and the drum, the action of the brake surface tending to increase the brake action. By means of the adjustment members 10, 6<b> the door may close in the desired manner. The brake surface may be eccentrically arranged in order that the check action decreases as the door nears its fully-closed position. Instead of employing a slidable wedge as the brake device, an eccentric or cam mounted to have a rotary movement on a spindle may be used. In this modification, the brake device is drawn between the brake-surface and the abutment 9 by a wedgelike action as the door closes. In addition to the usual door-closing spring, the device may be provided with a second coil spring which acts as a door check. Specification 220,528 is referred to.

Title: A process for the production of ice cream
IPC: A23G9/36
Filed: 1922-02-09
Abstract: 189,026. Maynard, L. H. P. Feb. 9, 1922. Ice-creams and like preparations.-In icecream manufacture, lactic acid bacteria are added to condensed milk to produce an acid fermentation, a separate mixture of a material rich in butter fat, for example fresh cream or cream made from butter, with sugar and an alkali such as lime, is made, and the treated milk and cream are mixed to form the ice-cream body. The milk is first pasteurized at 165‹ F., then cooled and the bacteria added. For slow fermentation a temperature of 32‹ F. may be used, and for rapid fermentation a temperature of 90‹ F. During fermentation a part of the milk sugar is changed into lactic acid. The treated milk is repasteurized and cooled. The cream is first homogenized and a portion of the necessary sugar is added; this sugar is dissolved without tending to crystallize the milk sugar. The mixture of the treated milk and cream is emulsified and aged by adding enzymes such as pepsin, rennet, or the like. The remaining sugar and flavour are added to the final mixture. the sugar being in finely divided form and held in suspension in the mass, the milk sugar being thus prevented from crystallising.

Title: Improvements in or relating to the welding of metal sheathed electric cables
Inventor: PAGE SIDNEY
IPC: B23K9/007
Filed: 1966-01-28
Abstract: 1,105,376. Arc welding systems. BRITISH INSULATED CALLENDER'S CABLES Ltd. 27 Jan., 1967 [28 Jan., 1966], No. 3906/66. Heading H2H. [Also in Division B3] In sealing an end of a metal sheathed mineral insulated cable by arc ; welding, a high frequency initiated timer-controlled D.C. preheating step is followed by a D.C. welding step and the timer is set in operations by the striking of the preheat arc. The seal is effected by melting the end of the sheath or by welding a cap to the end of the sheath. Actuation of a switch S1A, S1B connects a high frequency unit across the electrode E and the sheath W and energizes welding relay RC. When the preheat arc strikes, relay R responds to the arc current to set the preheat timer TA. At the end of the preheat period, timer TA sets the weld timer T and energizes relay B to shunt a resistance RX2 to increase the arc current. At the end of the welding period, timer T releases the welding relay RC. If the arc fails during the preheat period relay R falls back to reset the preheat timer TA.

Title: Improvements in or relating to character identifying apparatus
IPC: G06K9/64
Filed: 1962-02-01
Abstract: 937,147. Automatic character reading. INTERNATIONAL BUSINESS MACHINES CORPORATION. Feb. 1, 1962 [Feb. 16, 1961], No. 3955/62. Class 106 (1). In character recognition apparatus the character is scanned to produce a pattern of binary signals which are stored in a matrix of storage elements 104, Fig. 1, as shown in Fig. 2 (D, E, F), and also in a similar matrix in a register 105 in which the pattern is stored with an initial shift with respect to the pattern in register 104, both patterns then being shifted through the registers in step and logical units 107, 108, 109, 110, 111 respond to particular combinations of signals and deliver signals to counters 127-131. The process is repeated for three initial positions indicated by R1, C0, Fig. 2 (G, H, I); R1, C1 (J. K, L); and R3, C0 (M, N, O). R1, C0 indicates that the reference pattern in register B is displaced with respect to the pattern in register A by one row (downwards) and by no columns. C1 indicates a displacement by one column to the right. The initial shift is made by stepping pulses on line 125 from a control circuit 101. The rows of the matrices are connected in series so that it requires eight pulses to step the pattern to R1, C0. The counter 120 receiving the pulses gives a signal on lead 7 when eight have been counted. This opens gate 122 to pass a pulse via Or gate 121 to the control unit to stop the stepping. A signal also opens one of three gates in each of units 137-141. Both patterns are then circulated by sixtyfour shift pulses produced by " rollaround " counter 106 started by the signal from Or gate 121. At each step the logical circuits 107- 111 respond respectively to the following combinations: AB, i.e. a " 1 " in the A register and a " 0 " in the B; AB, i.e. " 1's " in both; Av, B, i.e. a " 1 " in either; #A#B, i.e. a " 0 " in both and #Av #B,.i.e. a " 0 " in either register. At the end of the circulation the values in counters 127-131 are gated to the appropriate count registers 151, 154, 157 and 163 and the pattern in register B is shifted a further position to R 1, C 7. Gate 123 then responds to enable gates in units 137-141 to transfer the counts to registers 152, 155, 158 and 164. The B register pattern is then stepped on until counter 120 gives an output on the 23 lead. The pattern is then in position R3, C0 and the process repeats. At the end of the three operations the values in the registers 151-165 are gated to recognition circuitry. This is constructed on the expectation that for each character each of the fifteen counts made will lie in a particular range. Appropriate register outputs are tested to determine whether the values therein lie within these ranges or outside them. The corresponding signals are combined in gating networks to mark one of a number of output leads representing the character sensed. If more than one lead is energized the character is rejected.
