Abstract: A television camera tube comprising in an evacuated envelope (1) an electron gun (6) to generate an electron beam which during operation of the tube is focused to form a spot on a photosensitive target (3), on which target a potential distribution is formed by projecting an optical image on it, which target, by scanning with an electron beam, provides signals corresponding to the said optical image, which scanning takes places in a line deflection direction and a frame deflection direction. When according to the invention the spot has an elongate shape, which shape is determined by a line at the edge of the spot which interconnects points having the same current density and of which     where k is the ratio between the lengths of the long and short axes of the spot and the long axis of the spot divides the acute angle between the line deflection direction and the frame deflection direction in such manner that     where β is the angle between the long axis and the frame deflection direction, a television camera tube is obtained the modulation depth of which is larger than in comparable tubes having a circular spot and the modulation depth of which is moreover less and substantially symmetrically dependent on the orientation of the usual test pattern for the modulation depth.

Abstract: A method is described of operating heat-exchanger apparatus comprising a plurality of heat exchanger units which are connected together in series for countercurrent flow of respectively a first heat exchanging medium which contains fluidizable particulate material and a second heat-exchanging medium. Each said unit comprises at least one vertical tubular duct in which said first heat-exchanging medium flows upwardly with said particulate material in a fluidized state and a compartment through which said second heat exchanging medium passes and through which said duct extends. The particulate material acting to remove deposits formed on the tube inside walls by the first medium. In order to achieve cleaning of the tubes in cases where a high rate of deposit occurs, flow of said second medium through each of the compartments is intermittently interrupted for a period of time, while flow through at least one other of said compartments is maintained. Thus the cleaning effect of the particles is increased in the tubes of the compartment for this period of time.

Abstract: A process for preparing polycarbonate type nonionic surfactant compositions comprising monohydroxy alcohols capped with polycarbonate groups. The surfactant compositions comprise aliphatic, nonaromatic cycloaliphatic or aromatic alcohols which have been capped with block polycarbonate groups formed by the reaction of the alcohols with ethylene carbonate in the presence of an alkali metal salt catalyst. The surfactant properties are varied by first reacting the alcohols with ethylene oxide to form a block polyether group cap on the alcohols before the reaction with ethylene carbonate or by further reacting the polycarbonate capped alcohols with ethylene oxide to form a terminal polyether block group. The surfactants are formed by reacting 2-20 moles ethylene carbonate and 3-50 moles ethylene oxide per mole of the alcohols.

Abstract: The disclosure relates to a stacker tyer for stacking newspapers received in a shingled stream from a printing press. A single centrally located stacker mechanism is flanked by a pair of compensators and outside compensators are a pair of tyers. Stacks are built in the stacker and moved laterally first to a compensator and then to a tying mechanism. Outside the tying mechanism are located a pair of delivery mechanisms which deliver the tied stack for further processing. The stacker is able to form either short stacks (bundles) or tall stacks (logs). In the case of bundles, the bundles may be either compensated or uncompensated: compensated logs are net built. The tvers are able to tie either a single strap around the midline of a stack or a pair of parallel straps offset to opposite sides of the midline of a stack using a single tie head. Moreover, the tyers are able to tie eitner bundles or logs. A shuttle mechanism is used to move the completed stacks from the stacker to one or the other of the compensators and from there to the adjacent tyer. A double-throw crank having a pair of connecting rods which are selectively connectible to the shuttle moves the stacks in. the above mentioned manner. The shuttle mechanism supports the leading and trailing edges of each stack as it is moved, and the back side and bottom of each stack is supported by fixed bottom supports and back supoports. Therefore, the back, two sides and bottom of each stack are supported during movement, and the stacks do not require realignment upon arrival at either the compensator sections or the tying stations.

Abstract: The invention is based on an integratable transistor amplifier circuit corresponding to the prior art and represented in Figure 1 of this application. According to the present invention, it is the aim to develop such a circuit in such a manner that it forms a low-impedance output stage which can be driven with voltages up to approximately UB- 2UBE and which only requires a low quiescent current in comparison with the known amplifier circuits of this type. For this purpose, the signal input in the low-frequency amplifier according to the invention is connected to the base connection of two mutually complementary transistors, the emitter connections of which are supplied by one constant current source each. The collector electrodes of these two transistors are jointly connected to the signal output of the amplifier. At the amplifier output, the emitters of two other mutually complementary transistors are also connected, the collectors of which are connected to the associated supply terminal and the base connections of which are connected to the emitter connections of the two first-mentioned transistors, in such a manner that the two transistors in each case connected to one another in the last- mentioned manner are also complementary to one another. <IMAGE>

Abstract: In a total power radiometer an amplitude modulated noise signal is injected into the radiation signal before it is mixed down to an IF frequency in a mixer (12). After the IF signal has been amplified and detected it is applied to an input of a d.c. amplifier (20) to which stabilization of channel gain and d.c. drift are applied. The gain of the amplifier (20) is stabilized by modifying the amplitude of its feedback signal using a gain control signal which is derived from the 10 kHz modulated noise signal present in the output of the amplifier (20). In the case of stabilizing the d.c. drift, the input signal to the d.c. amplifier (20) from the IF detector (18) is interrupted whilst the d.c. offset error is sampled by a capacitor which is connected to a comparator, the charge on the comparator, is compared with a reference voltage and the output is applied to an input of the amplifier (20) to correct the drift.
