Abstract: 970,871. Conveyance by air jets. BRITISH IRON & STEEL RESEARCH ASSOCIATION. Oct. 10, 1960 [Oct. 9, 1959], No. 34274/59. Heading B8B. [Also in Division B6] A method of supporting an article in spaced relation to a support surface which comprises forming a curtain of moving fluid directed from the surface to enclose a space between the surface and the article and to form and maintain within the space at least one cushion of pressurized fluid which tends to oppose a reduction in the spaced relation between the surface and the article. As shown, a strip 1 of material is guided in a serpentine path by fixed supports 2, each having a curved perforated surface facing the strip. Pressurized fluid, forced through the perforations, is trapped between the supports 2 and the strip such that the strip floats while being pulled by draw rollers 3. Alternatively, members 4 and 6, Fig. 2 (not shown), may replace the supports 2, Fig. 1, when the strip is being fed towards these members. The supports 2 may have orifices 7, Fig. 3, leading from a cavity 9 to supply the fluid curtain which maintains a fluid cushion within the spaces enclosed by the supports 2, strip 1 and fluid curtain. Further orifices 10, Fig. 4, augment the supply of fluid forming the cushion at a different, e.g. lower pressure. In other embodiments, Figs. 5a-5c (not shown), the orificesare formed by slits 11 and 12 which may be continuous or discontinuous. The orifices may be inclined towards the centre as shown in Fig. 6. As applied to a support table for sheets, the supporting jets may be turned on automatically by photo-electric means as the sheet passes over successive sections of the table.

Abstract: 487,156. Current and voltage measurements. GENERAL ELECTRIC CO., Ltd., and DUNHAM, C. R. Dec. 14, 1936, No. 34283. [Class 37] Apparatus for measuring the time integral of voltage, current or any other quantity that may be represented by a voltage, comprises (1) a linear electric amplifier, (2) a condenser adapted to be charged by the output current of the amplifier, (3) means to discharge the condenser when the potential across it reaches a predetermined value, the discharge ceasing when the voltage falls to a certain lower value and (4) a counting device to register the number of these discharges. The voltage whose time integral is to be measured, e.g. the voltage existing between an earthed supply conductor and a true earth, is applied at terminals A, B, between the cathode and grid of a pentode valve E working as an amplifier. A potentiometer K, L, connected across a D.C. supply at C, D, supplies the screen and control grid biassing voltages, and also supplies the control grid voltage of a gas-filled discharge device F connected in series with a current actuated counter H across a condenser G in the anode circuit of the amplifier. A high resistance N and condenser M prevent any high-frequency components in the input voltage from reaching the amplifier. The number of discharges in a given time is counted both with and without the input connected across A, B, from which data together with other known characteristics of the apparatus the time integral required may be calculated from a formula deduced in the Specification. Reference has been directed by the Comptroller to Specification 256,606, [Class 37].

Abstract: 1523079 Data transmission COMPAGNIE INDUSTRIELLE DES TELECOMMUNICATIONS CIT-ALCATEL SA 18 Aug 1976 (29 Aug 1975] 34357/76 Heading H4P In apparatus for producing an output wave which is phase modulated by input data and which is free from unwanted modulation products, the said wave is generated in the form of a sequence of digital values stored in a memory 4 arranged to define r groups of values obtained from a same given set of sinusoidal values multiplied by r predetermined coefficients k 1  to k r . A selection device 5 controls the read-out of the memory 4 at a frequency called the calculation frequency, the device 5 receiving, by way of a precoding assembly 1 and a delay line 2 r values of the modulation phase relating to r preceding calculating periods. The device 5 determines for each calculation period r data items respectively significant of the said r values and of the value for this period of the phase of a carrier signal derived from a source 6. The memory 4 delivers, in response to these r data items, r corresponding sinusoidal values and these are summed in an accumulator 7 to give the modulated wave in digital form. A digital-toanalogue converter 8 and a filter 9 convert the signal from accumulator 7 to an analogue signal M<SP>1</SP> suitable for applying to a telephone line, for example.

Title: Improvements in or relating to systems of subscription television
Inventor: LANCE THOMAS MARMADUKE CONSTAB
IPC: H04N7/167
Filed: 1956-11-09
Abstract: 842,101. Secret transmission. RANK CINTEL Ltd. Nov. 8, 1957 [Nov. 9, 1956], No. 34363/56. Drawings to Specification. Class 40 (4). [Also in Group XL (b)] In a television system, the vision signal is transmitted normally whilst the accompanying sound signal is rendered secret by a scrambling process, the nature of which is capable of alteration, and a control signal to permit privileged receivers to recover the sound signal is added to the signals in the vision channel. Preferably the mode of scrambling is changed at comparatively frequent intervals in an unpredictable manner. In one way of carrying out the invention, the sound signal is divided into three bands, each of which is arranged to be heterodyned by one of four oscillations which are selected by a control signal derived from the line-frequency synchronizing pulses. A corresponding set of four oscillations is provided at the receiver and to permit a reverse heterodyning process to be carried out the control signal is added to the vision signal preferably as modulation of a sub-carrier within the frequency range of the vision signal. The frequencies of the oscillations are advantageously chosen to be related to the line frequency or one of the carrier frequencies so that at the receiver they may be derived from the received signal and the need for receiver local oscillators avoided. In another way of carrying out the invention, the sound signal is divided into two bands, the upper band being transmitted unchanged whilst the lower band is modulated by one or the other of two oscillations for irregularly varying periods to yield beat frequency components having frequencies higher than those of the upper band.

Each trolley has wheels 56 and is connected with longitudinal lost motion through slots 46, Fig. 7 (not shown), with four bolts 41 on a base member 21 secured to the cables or rods. The base member has a pocket 27 to engage a projection 28 of the transport arm 29 which is pivoted at 53 to two guide rods 51 pivotal and slidable in slots 55 in the trolley frame by means of a pin 54. The arm 29 at its operative outer and has a roller 44 for engaging a car wheel rim and a projection 32 which can be latched below a spring-urged locking bar 33, as described with reference to Figs. 6 and 8 (not shown). The locking bar 33 is releasable by means of the plunger 31 of an electromagnet 30 when the latter is energized to place the plunger 31 in the path of a bell-crank 36 pivotally connected through a fork 35 with a stud 34 on the locking bar. When the cables or rods are operated to move the trolleys 5, 7 ... 17, 19 in the direction 38, the arm 29, e.g. of the trolley 5, will be raised when the associated plunger 31 is operated and a railway car will be moved a distance of 15 metres. At the same time the trolleys 6, 8 ... 18, 20 will move in the direction 39 and their arms 29 will be in the lowered inoperative positions. The motor 26 will then be reversed, in known manner, and the trolleys 5, 7 &c. will move in the direction 39 without effect on the moved car. However, the trolley 8 will then move the car another 15 metres. Trolleys of the rails 1 and 2 will thus alternately push the car along the track.

Filed: 1974-08-08
Abstract: 1471760 Calendar watches ETA AG EBAUCHES-FABRIK 8 Aug 1974 [9 Aug 1973] 34949/74 Heading G3T  In a calendar timepiece having tens and units indicators 10, 12 for the date and a further indicator for the day of the week, the units indicator 12 is driven from hour wheel 5 via a wheel 15 which is mounted coaxially with a wheel 22 for driving the tens indicator 10 from the units indicator, and parts 29, 30 for stepping drive of the day indicator are mounted coaxially with a calendar correction mechanism 25. In the watch shown, the wheel 15 is rotated once per day via an intermediate wheel 37 and carries a resilient finger 16 to engage teeth 17 of units ring 12. Two diametrically opposed teeth 21 on that ring can engage star wheel 22 to advance a star 9 carrying tens disc 10. The date digits are visible through a window 11 in dial 8. A single-toothed disc 6 is attached to the hour wheel 5 and intermittently advances wheel 30 which is coupled to wheel 29 driving a wheel and arbor 7. A hand on that arbor indicates the day and AM/PM.  The date may be set by pulling out stem 24 and turning the watch hands to and fro around midnight, since the finger 16 rides over teeth 17 when wheel 15 turns anti-clockwise. Alternatively the calendar correction mechanism 25 may be used, comprising a hub 27 pivoted on a screw 26 and fixed to a wheel 31. The wheels 29, 30 are frictionally coupled to the hub. If stem 24 is placed in a calendar correcting position and rotated to turn a rocking pinion 32 anti-clockwise, an upper toothing on the pinion drives the wheel 31 and thus the hub 27 and wheel 29 to change the day indication. Opposite rotation of the stem drives pinion 32 clockwise and into engagement with correction toothing 34 on the ring 12 to advance the date.
