Filed: 1982-02-22
Abstract: Containers (19) (made of, for example, metal, glass, 
plastic or fiber) are sterilized in a steriiizer (21) of packaging 
apparatus having a helical or spiral conveyor belt (36) within 
an insulated casing, (31) through which air above atmos­
pheric pressure at up to about 500 °F (260 °C) is circulated 
by means of a heater (46) and blower (47), in a recirculation 
path. The containers then travel along a straight-line 
encased conveyor (22) where sterile air above atmospheric 
pressure prevents ingress of non-sterile ambient air. During 
part of the path through the straight-line conveyor, the 
containers are driven by a helix (71) which forces the con­
tainers into close proximity. Pre-sterilized, preferably 
cooled, product is delivered into the containers preferably 
through a curtain, slit-type filler (111). The speed of the 
containers is timed so that the desired product volume is 
delivered into the containers. Thereafter, filled containers 
are accepted by a container closing machine (24). Container 
lids (18) or covers are sterilized in a section of the apparatus 
where lids are moved along a conveyor and sterile air which 
has been heated is forced by a blower (161) into the lid 
sterilizer section. The lids then travel up a tunnel at greater 
than atmospheric pressure, where they are cooled and de­
livered to the closing machine. The closing machine applies 
the sterile lids to the containers at greater than atmospheric 
pressure.

Abstract: Information concerning the path of an adhesive-applying 
nozzle (28) and/or a lasting roller (176) relative to a three-di­
mensional shoe bottom surface is obtained using a flat insole 
in combination with a grid of flexible transparent material. The 
grid has a datum (10), a centre line (12); [representing a linear 
path of a tool carrier (26)] and a plurality of transverse lines 
(14), the spacing between each pair of adjacent transverse 
lines representing unit time. The transverse lines adjacent to 
the datum are more closely spaced than those beyond, the prin­
cipal component of movement of the tool (as opposed to the 
tool carrier) in relation to the shoe bottom, at the datum (i.e. 
the toe end), being widthwise rather than iengthwise. Heel 
height information may also be supplied to the computer, 
which is programmed to modify the digitised information ac­
cordingly for the region from the ball region to the heel (which 
constitutes some 60% to 65% of the overall shoe length). The 
information may also be modified according to the particular 
arrangement of the nozzle and roller supports.
Patent EP-0098146-A3 (EP)
IPC: E06B9/36
Filed: 1983-06-28
Abstract: A vertical blind system comprises a rail (1) having two 
outer channels (7) and a centre channel (8). The rail ends are 
closed by pulley blocks (15). An endless draw cord (2) runs 
along channels (7) round one pulley (16) and out through the 
opposite pulley block to form a loop (20). Vertical blinds (5) 
are suspended from small discs (3) that extend across the rail 
(1) into the outer channels (7) and rest on both runs of the 
draw cord (2). Frictional contact between the cords (2) and 
discs (3) is increased by a weight carried by each blind (5) 
and by serrating the under surface (30) of the discs (3). A 
master slider (25) linked to one end of disc (3) extends across 
the rail (1) and is non-slidably attached to one run of the draw 
cord (2). The disc (3) are preferably linked by flat strips (14) 
and are attached thereto by a pivot pin (19) for rotation about 
a vertical axis. Each strip (14) contains a lengthwise slot (26) 
which is engaged by a cranked T-element (30) of an adjacent 
strip for movement along the slot (26). To draw back the 
blinds the master slider (25) under the action of draw cord (2) 
causes the discs (3) to move successively into contact 
causing the blinds (5) to gather at one side of the window, 
the strips (14) sliding one beneath the other. To move the 
blinds (5) in the reverse direction the master slider (25) pulls 
its attached disc (3), successive discs (3) being pulled by 
linking strips (14) when the T-element (30) of one strip (14) 
reaches the end of the slot (26) with which it is engaged. 
Rotation of the discs is achieved by pulling the appropriate 
side of loop (20) of draw cord (2), the frictional engagement 
between the disc and the draw cords causing the discs (3) 
and associated blinds (5) to rotate.

IPC: H04M19/08
Filed: 1984-02-03
Abstract: An inductance simmulation circuit for connection be­
tween data handling apparatus, such as a modem, and a 
transmission line (3) includes an inductance simulation cir­
cuit (12) for providing a low d.c. resistance to allow circula­
tion of a line holding current, whilst presenting a high a.c. 
shunt impedance to the audio data tones on the line. The 
simulation circuit (12) comprises two transistors (13, 14) 
connected as a high gain amplifier across an input resistor 
(22) in the modem/line coupling circuit (1-24). The audio 
tones are fed to the input of the amplifier via a capacitor (18) 
and the amplifier applies amplified tone signals across the 
input resistor to augment the tones thereacross. The con­
ductive transistors also act as a low resistance connected 
across the input resistor for the passage of the line holding 
current. The simulation circuit acts, in effect, as an induc­
tance, withouth the use of inductive components. The input 
resistor is effectively connected, in series with two zener 
diodes (9, 10), across the line, and the series circuit receives 
the line voltage and produces therefrom positive and nega­
tive power supplies (7, 11) for energising the entire modem. 
No further power supply is necessary. The coupling circuit 
also includes a rectifier bridge (4), or a relay with change­
over contacts, for ensuring that the current flow in the series 
circuit (9, 10, 22) is of the correct polarity, irrespective of the 
polarity of the line voltage. Data signals are fed into and out 
of the modem via optocouplers (49, 95) so that dangerous 
voltages cannot reach the modem and thence the line. The 
modem may be constructed as an integrated circuit on a 
single chip with relatively few discrete components.
