IPC: B65B7/20
Filed: 1939-06-16
Abstract: 530,389. Packeting. ROSE, A. G., and ROSE BROS. (GAINSBOROUGH), Ltd. June 16, 1939, No. 17601. [Class 94 (i)] A method of producing filled and sealed cartons comprises feeding a carton, open at both ends, on to an endless conveyer which carries it past mechanism for closing and sealing one end, discharging the carton on to a filling platform, inverting and filling the carton, and then transferring the filled carton to another part of the conveyer which carries it through mechanism for sealing and closing the open end. An operator takes a collapsed carton from a stack 6, opens it into tubular form, and places it upright on a horizontal support 8 with the two outside flaps projecting past the edges of the support, the flaps at the top of the carton remaining open. The operator then pushes the carton 5 along the support 8 to a position where it is engaged by one of a series of pushers 11 attached to a chain conveyer 12. The pusher moves the carton through flap-folding and sealing mechanism 16 of known construction, and the carton with the top closed is deposited on a shoot 31 that discharges it on to the filling platform 33. An operator takes the carton and fills it, and then places it between side guides 37, 38 on a further travelling band 36 which carries it forward until it is stopped by one end of another side guide 41. The carton stops until it is moved by a plunger 43, operating in timed relation with the conveyer 12, into the path of a pusher 11. The carton is then moved by the pusher through further flap - folding and sealing mechanism 46, the closed carton finally being deposited between delivery bands 51, 52. The positions of the carton-supporting members and the band 36 are adjustable vertically to suit cartons of various heights and the side guides can be adjusted to suit cartons of various widths. The manual operations may be replaced by mechanism to make the entire operation automatic.

Title: Telegraphy system
IPC: H04L25/49
Filed: 1963-05-06
Abstract: 1,011,399. Data transmission; transistor pulse shaping circuits. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. May 6, 1963 [May 7, 1962], No. 17820/63. Headings H3T and H4P. In a telegraph system in which there is a large information content in a given bandwidth, binary input pulses to the transmitter are converted to a data pulse train to be transmitted, in which successive transmitted pulses have the same value if the corresponding input 1 bits are adjacent, and have the opposite value if the corresponding pulses are separated by one or more 0 bits. The 0 bits are transmitted as a like number of pulses of intermediate value. In a first embodiment, the transmitter, Fig. 1A, has an input E, Fig. 1B, at 6000 Bd. which is to be transmitted over a low-pass channel having a bandwidth of 3000 Bd. Odd and even pulse are separated, spI, spP, and stretched, elI, elP. An oscillator Os provides a sinusoidal signal OS at a frequency of one half the data bit rate and which is phase-shifted by + 45 degrees and - 45 degrees, d +, d- , raised in D.C. level, eaI, eaP, and gated with elI, elP in coincidence gates PI, PP. The resultant waveforms pI, PP are added to give adI which is fed to coincidence gates P<SP>1</SP>, P<SP>11</SP>. These gates are alternately open, under control of baI, baO from bi-stable circuit Ba which is fed by the original data E after being stretched, el, and differentiated, gI. The output of gate P<SP>11</SP>, p<SP>11</SP>, and the inverted output, ir, of gate, P<SP>1</SP>, are added to give ad2, this waveform being smoothed in Cr so that the resultant waveform cr can be transmitted over a 3000 Bd. channel. Circuit Cr is shown in Fig. 1C and comprises diodes Rd1, Rd2 working on the parabolic part of their range. At the receiver, Fig. 3 (not shown), the input signals are frequency doubled to provide a signal which is gated with clock pulses at bit frequency derived from the doubled signal. The output of the gate is at 6000 Bd. and is identical to the original data E. An arrangement for transmitting in a bandpass channel is described with reference to Fig. 2 (not shown) and the receiver with reference to Fig. 4 (not shown). The data signals are divided between odd and even channels as before and each channel includes means for deriving a quarter bit-rate signal which passes to a modulator, the modulators being fed with carriers phase displaced by 90 degrees. The modulated signals are added and transmitted. At the receiver the signals are separated to odd and even channels, frequency doubled, gated, and summed to reproduce the original data. Fig. 5A (not shown) illustrates a variation of the arrangement described above with reference to Figs. 1A, 1B.

Title: Improvements in or relating to the manufacture of cement
IPC: C04B7/44
Filed: 1924-07-28
Abstract: 243,410. Rigby, T. July 28, 1924. Rotary kilns.-The invention relates to cementmaking processes and apparatus of the kind wherein the slurry is dispersed in the upper part 'of the rotary kiln so that it is partly dried before coming into contact with the kiln wall. One feature of the invention consists in distributing the dispersed slurry over a considerable area of the kiln wall, by means of either a single spraying device or a number of spraying devices 7, 8 as shown in Fig. 1. The distribution is preferably controlled so that the slurry deposited nearest the end of the kiln undergoes the least drying. A second feature consists in placing the spraying apparatus outside the kiln, e.g. in a chamber 13 adjustable axially within an aperture in the back wall 5 of the kln head, as shown in Fig. 1. A third feature consists in providing an alternative feed pipe which can be inserted through an aperture 31 in the top of the kiln head when the sprays are out of action. According to a further feature of the invention the gases leaving the kiln are brought into contact with slurry, whereby the latter is concentrated before being dispersed in the kiln and also the gases are freed from particles of raw material which they may have carried out of the kiln. This may be effected either by dispersing slurry in the gases outside the kiln, or by filling the base of the kiln head with slurry, which is agitated by air blown through pipes 39, as shown in Fig. 4. Specification 199,056, [Class 22, Cements &c.], is referred to.

In the system shown, connections are set up between a calling point A and a called line A<1> belonging to the same group, over rotary line-switches C, C<1> of the no-normal type and a Strowger connector H, all operating in known manner. Each line-switch is provided with a fourth wiper 25 connected over a contact 19 and a lead 90 to a point in a battery B<1>. The leads 90 belonging to any one group of lines are all connected to the same point in the battery B', but the leads 91 belonging to any other group are all connected to a different point. Each connector H is provided with a discriminating relay 47, the circuit of which extends right through the connection from the lead 90 of the calling line to the corresponding lead of the called line. In the case of an attempted connection with a line in a different group, the circuit of the relay 47 is connected to different potentials at its two ends, and the relay energizes to close a contact 65 in a circuit for the busy relay 45, which responds to prevent the connection and to give a busy signal to the calling subscriber as in the case of ordinary busy calls. The additional battery B<1>, consisting of dry cells, is provided to prevent unequal loading of the main storage battery B, with which it may be connected in parallel thus lengthening the life of the dry cells. If there are only two groups of lines, the additional battery is unnecessary, and the leads 90. 91 may be connected to the main battery and earth leads respectively. If the total number of lines necessitates the use of group selectors, the extra conductor which leads to the discriminating relay at the connector is extended through the selector over contacts controlled by the switching relay of the selector and over a fourth wiper. The connector may be modified in known manner to permit connections to a main exchange.
